Situation Analysis

Water is an invaluable resource used in every manufacturing facilityaround the world. It is the one resource that most people may take forgranted, but which plays an essential role in general industry.

Water is utilized in many ways:It is used as a key ingredient of many different products from pizza sauce towindshield cleaner, and in some styles of spray booths,it is used to trap theover spray from the spray gun.It is even used to wash down work areas to make them look nice and clean.

No matter how water is used in a manufacturing or processing plant, itbecomes contaminated in some fashion.

It may be contaminated with chemicals or waste or even by high heat.

But either way, it is not as pure as it was when it came in.

In all situations it must be treated before it can be re-introduced back into themunicipal water system.

Situation Analysis

The Waste Water Treatment Industry is growing worldwide due toincreased awareness, and enforcement of regulations that put stringentcontrols over how hazardous waste is dealt with.

In most areas of the industrial world, manufacturers must find a way toensure that the water they use within their manufacturing site leaves in thesame, if not better, condition than they received it.

Manufacturing facilities do have options in how they deal with theirhazardous waste:

They can collect their hazardous and non-hazardous waste and ship it to anindependent wastewater processing plant.They can build a wastewater treatment plant within their facility.

• Although probably not a preferred alternative, it is the correct decision from a financialperspective. Independent processing facilities charge for their services and themanufacturer still needs to collect the contaminated materials

Application Basics

The waste water treatment plant separatesThe non-fluid and fluid particlesTreats the fluids to eliminate any hazardous elements

Collects the dissolved particles before re-introducing the now clean water backto the environment and disposing the solids waste.

Application Basics

Generic Waste Water Treatment Plant

Most companies will route their contaminated water/oil into a separatetreatment area from their contaminated water/chemical wastes.

Application Basics

Oil – Water Separation:When the waste stream contains oil, it must be separated prior to treating thewater.

The oil / water mixtures can come from various areas in the plant, but typicallythe main generator of this mixture is the machine tool area.The oil / water mixture is either pumped to a central area for separation, or itwill be done locally in the machine tool area.

Most companies will separate the oil / water mixtures local to the machine tool.

The oil / water mixture contains a combination of tramp oils, machiningtool coolant, and water.

Many companies capture the machine coolants and oils for re-cycling.Oil, being lighter than water, will float to the surface of the water over time.

An oil-water separator is used to skim the oil from the surface. The oil-waterseparators come in two different designs:

• Belt Design

• Oil Skimmers

Application Basics

Belt Design: Typically used at the machine tool areaThe tramp oil / coolant/ water mixture settles in a reservoir that will vary in size.The reservoirs are generally located next to the machine tool.

A belt, typically made of polypropylene, is placed into the reservoir and justbelow the surface.

• As the belt slowly moves, it captures the tramp oil and conveys it away from thereservoir. As the oil makes its’ way up the belt it comes in contact with a scrapperwhich captures the tramp oil.

• The belt maybe on a timer, but it usually works continuously.

• The collection container can be large, dependent on the size of the machine tool.

• In the case of a larger container, a pump may be used to empty the container

Another derivation of the belt design is the use of a turning disc / wheel.• The disc / wheel sits perpendicular to the reservoir, with its lower half sitting in the

tramp oil / coolant/ water mixture.

• As the disc / wheel turns it captures the tramp oil which is collecting on the surface.

• A scrapper is used to deflect the tramp oil from the disc / wheel and into a collectioncontainer. The container is more similar to a tray than a pail.

Application Basics

Oil Skimmers: Typically used in a central collection site.The tramp oil / coolant/ water mixture is collected in a central holding tank.These tanks vary in volume and size. No matter what they look like, they workthe same.As the tramp oil starts to separate, it floats to the surface of the tank. It isimportant that the tank remains static.The longer the tank remains motionless, the thicker the level of oil will be on thesurface.

• A pump is used to remove the floating oil. Typically the collection hose / pipe will bepositioned just below the surface, but within the level of the stratified oil.

• Although some water/ coolant may be pumped, it is the intention to only pump the oil.The pump operates on a timed schedule to allow the tramp oil to float to the surfaceduring the interim.

When a pump can be used, it is generally a double diaphragm pump.• Although a centrifugal pump is typically used to pump the machine tool coolant, it is

not a good alternative for pumping that material with oil in it as well.

• The centrifugal motion will emulsify the mixture and slow the time for separation.

Application Basics

Ion Exchange:Dependent on the manufacturing process that created on the waste stream,there will be a variety of contaminates that need to be removed or neutralized.

Some of these contaminants are metals, such as cadmium, copper, nickel, andchromium.Utilizing an ion exchange process, these materials are changed into non-toxicmetals that can be put back into the water system.

The basic ion exchange system consists of two ion exchange columns locatedinside of each of the two regenerative tanks and inter-connecting piping.

Pumps are used to feed the columns and to inject the acid and causticresins after the regeneration process.

Diaphragm pumps are used for the high capacity transfer from one tank toanother.

Application Basics

Chemical Treatment:Cyanide must also be removed from the wastewater.Cyanide is rendered harmless by treating the water with chemicals.

• The step is to raise the pH level of the solution to 11, by adding an alkali. Sodiumhydroxide is typically used.

• The next step is to add chlorine, typically sodium hypochlorite.

• This changes the cyanide into a cyanate. Additional chemicals are added that turn thecyanate into carbon dioxide, which is harmless.

Dependent upon the size of the water treatment systems and the subsequentvolume of the wastewater stream, the system will either be incremental dosingor continuous flow.

• The amount of chemical dosed is calculated in gallons per hour.• Continuous flow means the chemicals need to be injected over time rather than at

one time.

Application BasicsChemical Treatment

Metering pumps are used for dosing of the sodium hydroxide and chlorine intothe holding tanks.

Typically these are mechanically operated diaphragm pumps that have fineresolution and with a very high accuracy.

• Metering pumps have the ability to run at very low flow rates for continuous metering(for example _ gallon per hour.)

• The usage of remote actuated air operated diaphragm pumps is becoming moreprevalent.

Application Basics

Chemical TreatmentDouble diaphragm pumps do not have the accuracy of a metering pump, but inmany cases the end user doesn’t require a tight accuracy.

The main determining factor is the volume output, which may be lower than theminimum output of a diaphragm pump.

• Quarter inch pumps are generally used for their smaller volume per cycle. Kynar isthe material of construction for sodium hypochlorite and polypropylene for the sodiumhydroxide.

• Pumps are also used for adjusting the pH in the tanks. Maintaining a consistent pH isimportant to produce the right amount of flocculation once the polymers are added.The pH is monitored by sensors, which turn on the appropriate pump to lower or raisethe pH.

Application Basics

Polymer Feed:After all of the oils, cyanides and metals have been removed or neutralizedfrom the wastewater, there will be leftover particulate floating in the solution.

Polymers are added to the wastewater to concentrate the solids. Thewastewater particulate will start to flocculate prior to going into the clarifier.

• The pumping system for the polymer feed is the same as the chemical feed.Dependent on the tank size, the flow of wastewater stream, and the subsequentamount of polymer required, the size of the pumps will vary. Quarter and half inchpumps are generally used.

No pump is required to transfer the wastewater to the clarifier tank since theclarifier tank is generally lower than the holding tank. This allows for a naturalflow of treated wastewater constantly flowing to the clarifier.

Application Basics

Clarifier:The clarifier is a tank with a series of parallel plates. These plates are called a“lamella plate pack.”

The treated wastewater flows around and over the plates. As the flocculentcome in contact with the plates they are captured momentarily. The flocculent,having lost its’ momentum slowly settles to the bottom of the tank where itcollects as a sludge.

As the treated water works its way through the plates, it gradually becomes freeof any solids. The water exiting the clarifier goes into a final holding tank.

• A pH monitoring system checks the pH level in the last tank and activates theappropriate pump to lower or raise the pH prior to exiting the treatment area.

• The treated water is either returned to municipal sewer system or in some cases maybe used again in the manufacturing process.

Application Basics

Clarifier:Metering pumps are used to supply the chemicals for the final pH adjustment.These pumps are similar to the pumps used in the previous steps.

• Mechanically actuated diaphragm or remotely actuated air operated diaphragmpumps are used.

The clarifier tank has a bottom outlet. A pump will pull the settled particles fromthe bottom of the tank and transfer the sludge to a filter press or some other de-watering device

Application Basics

De-wateringFilter presses are the most common means of de-watering the sludge comingfrom the clarifier.

• A filter press is made up of several vertical plates fitted with a filter cloth betweeneach plate.

• When the filter press is closed the plates become closely fitted together. The sludgeis pumped into the plates, with the solids collecting in the cloth filter and the waterflowing through.

There are two basic filter press designs.• Uses the sludge supply pump output pressure to pack out the sludge and produce a

dry cake.

• Uses a secondary hydraulic pressure device to do a final compaction. This pumptakes over after the sludge supply pump has stalled.

In either design, once the filter press is opened, the resultant solid cake ofsludge falls into a collection bin located under the filter press.

Application Basics

There are typically five stages in the de-watering process. Each stage isrun at a different working pump pressure:

Stage One 20psi pressure for 20 minutes

Stage Two 40psi pressure for 20 minutesStage Three 60psi pressure for 20 minutesStage Four 95psi pressure for 20 minutes

Stage Five Opening of the Filter press to drop the dry cake takes 30minutes

De-watering is a constant process.Operators need to maximize the time the pump runs to create a dry cake.The operator only opens the filter press once the pumps stop. If the pump stallsbefore producing a dry cake, the operator will either let the filter press gothrough its cycle again or accept the wetter cake.Disposal cost for wet cake is higher than a dry cake. Running the filter pressthrough an additional cycle slows the water treatment system. In many casesthe end user may need two filter presses to keep the processing running.

Application Basics

De-wateringDiaphragm pumps are commonly used as the transfer pump for the sludgefrom the clarifier to the filter press.

As the sludge builds up in the filters, the resultant back-pressure slows downthe diaphragm pump, and eventually stops it.The ability of the diaphragm pump to operate at higher back-pressure is a greatadvantage to the operator.

• Cast / ductile iron pumps are typically used in this application.

Pumping SolutionsAir operated pumps are inherently explosion proof.

Many of the materials pumped have a low flash point, which requires specialcare

Adding an optional explosion proof electric motor onto a centrifugal or gearpumps greatly increase the cost of these pumps. There is no price premium withan air operated pump

Air operated pumps stall against pressure.Air operated pumps operate when air is applied and stop when the fluid line isshut off. It does not consume energy while it sits idle.

Electric driven pumps require a relief valve or by pass line to operate in a similarfashion. Although the pump is not pumping, the motor still may be on

Double diaphragm pumps are simple to understand and relatively low costDiaphragm pumps are easy to repair and less expensiveGear pumps requires a higher technical expertise for service and thewear items are more expensive to replace

Pumping Solutions

Large passages enable double diaphragm pumps to pump highly filledmaterials without short term significant wear

Other pump technologies are not as forgiving as a diaphragm pump. Significantwear will occur in gear pumps

Double diaphragm pumps have no packings or mechanical sealsDiaphragm pumps can run dry without any harm to the pump

Electric gear pumps’ life is severely reduced if they run dry for any amount oftime

Graco Solutions

Graco’s Husky Diaphragm Pump solutions have additional features andtechnical benefits that improve the reliability and performance over thecurrent diaphragm pumps used in the applications described.

One common center section and the same air valve used in all 1”, 1 _” and2” pumps:

Reduced number of spare parts needed to service a greater number of pumpsizes

Maintenance personnel become more familiar with the products fasterCompetitive manufacturers have multiple designs that may not be available inall sizes of pumpsCommon center section and air valve on the _” and _” pumps.

Same air valve technology used in _” to 3” pumps

Graco SolutionsAll of the air valve parts can be externally serviced without taking the entirepump apart:

In all 1”, 1 _” 2”, and 3” pumps, the air valve parts can be easily accessed bytaking off six screws from the air valve cover.

On the _” and _” pumps the air valve parts are accessed by unscrewing the airvalve cap.Competitive diaphragm pumps need to be completely taken apart to access theair valve and actuator pins.

Documented flow rates that are not affected by type of diaphragm usedAn end-user will purchase pumps based on specific applications requirements,among them is the preferred flow rate. Flow rate is influenced by the viscosity ofthe material pumped, the airflow speed through the pump, and stroke length ofthe pump.Wilden, Yamada, and Versa-Matic, change the stroke of their pump when theyuse PTFE diaphragms. This reduces their flow maximum flow rate by 20– 25%compared to their other elastomers.

Graco Solutions

Documented flow rates that are not affected by the installation of an airmuffler

Wilden, Warren-Rupp, Aro, and Versa-Matic do not include a muffler on their 2”and 3” pumps.

Installation of the muffler will slow the pump speed. Their documented flowrates need to be reduced by 20% to reflect actual performance.All Graco diaphragm pumps are shipped with a muffler and are not de-rated fora specific diaphragm material

Bolted Pumps in all materials for 1” and larger sizes:Pumps that are bolted together are easily assembled

Wilden 3” pumps that use PTFE diaphragms require the use of a hydraulicpress to push fluid end and center housing together requireClamps used in 1” and larger pumps will lose their clamping integrity afterrepeated dis-assembly. In many cases after just three pump repairs, theclamps need to be replaced

Graco Solutions

Longest warranty period among any diaphragm pump manufacturerFive- (5) year warranty period for diaphragm pump fluid endsFifteen- (15) year warranty on the center sections:

Longer warranty period is a good indicator of manufacturers confidence intheir product design and manufacturing quality

No diaphragm pump manufacturer has a comparable warranty period

Wilden, Warren-Rupp, Versamatic, all have one (1) year warranty periodsAro has a five (5) year warranty period

Selecting the right pumping solutionSelection of the correct pump size for a specific end user

Utilize the Husky DPS (Diaphragm Pump Selection) Software. The software isincluded in the Process Equipment catalog.

To select the right pump, the following application criteria needs to be inputted:The fluid flow and working pressure required for the application

• Maximum pressure of a diaphragm pump is at zero flow

• Maximum flow of a diaphragm pump is at zero pressure

• Any fluid pressures and flow rate inside of those extremes will reduce both

Viscosity of the fluid• Diaphragm pump performance curves are based on water.

• A viscosity greater than water will reduce the maximum flow capacity

Distance between the supply container and the pump, and the head pressure• Diaphragm pump performance curves are based on a positive inlet pressure

• Anything less than a positive inlet pressure will reduce the maximum flow

Husky DPS automatically calculates the affects of pressure, flow, andviscosity and head pressure and selects the pump sizes that will work.

Selecting the right pumping solution

The Husky DPS will listall of the options forthe wetted ends of thepump that arecompatible with thefluids being pumped.

All of the materials listed will all work, but some materials are more accepted than others.Unless the pH level of the fluid directs otherwise, aluminum is the most common material for the wetted ends, andis used for both solvent and water based materials.This matrix should be used to determine the best solution from an economic viewpoint.

The Husky DPS lists all of the materials that will work with the fluidspumped.

As a general rule:Polypropylene wetted ends: the xxx-911 combination will always work

• Use the xxx-966 combination for lower cost alternative with less acidic fluids

Stainless Steel wetted ends: the xxx-336 is good for higher viscosity fluids• Use the xxx-666 combinations as a lower cost alternative with lower viscosity
