Basics of Chemical

Treatment

Chemical treatment is still an essential component in many water and wastewater

treatment schemes. The general purposes of the chemical treatment are: removal of

suspended solids (turbidity) from the water; pH adjustment; removal dissolved

material in the water; improve water quality.

The Basic of Chemical Treatment that

Filter Innovations Inc. provides, is:

- pH adjustments and control

- Coagulation / Flocculation

- Precipitation

- Clarification

Basics of Chemical

Treatment

When to use a Chemical Treatment System

- To meet the local water discharge requirements, and save the customer

money in sewer charges or water removal charges

- To provide a quality of water required for the process

- Recovery of valuable product

- Remember: the smaller the particle the longer it takes to settle

0.0001mm diameter particles take 4 months to settle 10

What can be done using a chemical Treatment Systems

- Removal of suspended solids from the water (Turbidity)

- pH adjustment

- Remove dissolved material in the water

- Improve water quality

- Remove?????

pH Adjustment

pH is a measure of the activity of hydrogen ions (H+) in solution and,therefore, its acidity or alkalinity

Coagulation

Coagulants neutralize the repulsive electrical charges (typicallynegative) surrounding particles allowing them to stick togethercreating clumps or flocs.

Flocculation

Flocculants facilitate the agglomeration or aggregation of thecoagulated particles to form larger floccules.

Chemical Testing

Easy performed by Filter Innovations to optimise and determine theright mixture of pH Adjustments, Coagulants and Flocculantchemicals to ensure

a trouble free system.

Requirements:

pRepresentative sample of water to be treated,

5 gallons minimum for testing

pWater lab test report

pWater quality discharge requirements

pFlow rate in final system

pOperetor involvement requirements

Clarifying the Wastewater

Once the water has been effectively pH Adjusted, Coagulated andFlocked the resulting sludge and clean water must be separated tofinish the process.

Slant Plate Clarifier (Lamalla)

pUtilizing gravity to separate solids in wastewater is the mostenergy efficient

pSlant plate is used to decrease the distance a particle has to fall

before it hits a surfacepThe flow rate of the clarifier is based on the particle density,surface area, fall rate, loading and temperature.

DAF Dissolved oxygen

Aeration Flotator

Membrane Biological Reactor (MBR) vs.

Conventional Activated Sludge TreatmentIn certain cases when sludge is less dense than

water, or neutrally buoyant, Dissolved AirFlotation (DAF) is used in Chemical TreatmentSystem.

p DAF utilizes billions of micro bubbles that attachthemselves to the flock and rise to the surface.These bubbles are known as whitewater.

p DAF unit requires a mechanical skimmer toremove floating sludge.

p Although, DAF unit needs more power to runcomparing with gravity settling clarifier, it isefficient when used in the right environment.


14/28


Particulate Removal Filters


Conventional Activated Sludge TreatmentpWhen sludge after coagulation/flocculation treatment is not desired and consists of the very

sensitive flocks, Filter Innovation offers following products as bag filters, self indexing filter, cartridgefilters or filter press, which support higher filtration requirements.

pAfter sludge/water separation, if further polishing is required, water is pumped into the vessels with

specialty media and/or activated carbon.

MBR BASICS

MBR Filtration Principle Out-In

Membrane pore

size 50 m

MBR - Wastewater Treatment


17/28


MBR System Elements

Laser-welded Plate-and-Frame Membrane

Plates is a key element of the membrane filter.

Membrane Module is a complete unit

consisting of membrane plates, supportframe, feed inlet retentate, and outlet

permeate ports.



18/28



Depending on applications MBR can be

presented by different kinds of aggregates

Whole membrane filtration system includes:Membrane filters (membrane & support frame)

Permeate withdrawal system

Air scouring blower system

Permeate & mixed liquor recirculation pumps

Membrane cleaning system

Programmable logic controllers (PLCs)

Membrane filters are submerged into the treated water. The filtrate is drawn through and out of

the filters by the slightly negative pressure of only 0.1 bar (0.47 psig)

KEY BENEFITS OF MBR

HIGH WATER QUALITY Effluent is disinfected and particle free

RAW WASTEWATER AERATION TANK EFFLUENT WATER

BOD < 5 mg/L

TSS < 1 mg/L

Turbidity < 1 N.T.U.

Total bacteria removal

99.99% virus removal
