PRE-ENGINEERED PLANTS - PRO SYSTEMS

3


Compact, pre-engineered systems PRO-30, PRO-80 and PRO-100 are designed for the purification of the well water, whereas the main task is iron and manganese removal. Additional units for the water purification such as UV sterilization and activated carbon filters can be added to the system if the analysis proves it necessary. The capacity of PRO-30 is 30 m3/h and is sufficient for the 4,800 inhabitants settlement, the capacity of PRO-80 is 80 m3/h and is sufficient for the 12,800 inhabitants settlement. Whereas, the capacity of PRO-100 is 100 m3/h. It is sufficient for the 16,000 inhabitants settlement (according to European standard, consumption is 150 L per inhabitant).

PRO-30, PRO-80 and PRO-100 systems design is compact and fits inner dimensions of ISO container of 12 m (40 ft.), which makes those systems easier for transport. During transporting, units for chemical dosing, potassium permanganate and calcium-hypochlorite are mounted on an operational platform.

Intake water requirements:

Ph value: 7 – 8 Turbidity: maximum 5 NTU Total hardness: < 200 mg/l calculated in CaCO3 Organic material: maximum 2 mg/l Iron: maximum 1.50 mg/l Manganese: maximum 0.30 mg/l

PRO SYSTEM can be built in two basic versions: manual and full automatic operation. In systems with manual operation, all process valves are hand operated by operator, which is necessary to perform periodical filter backwashing. Full automatic operation for PRO-30, PRO-80 and PRO-100 relay on pneumatic operated valves and system can be operator free, just periodical check for consumption chemicals on alarm calls.

FILTERS SYSTEMS

4


Filtration is a crucial process in water treatment systems. Filtration units are of different designs and purposes. They are used in all parts of water systems for filtration of unprocessed water and water in the final procedure of refining. Sand filters and filter cartridges are used to remove suspended and colloid particles from unprocessed water.

SAND FILTERS: Fast sand filters or filters under pressure are used to separate all suspended material and particles of 30 – 60 μm, or so-called mechanical impurities. Filtration under pressure can be performed in one or more parallel filters. The construction of filters consists of vertical or horizontal steel vessel, cylindrical in shape with shallow bottoms, suitable supports and handles, and all the necessary connections as well. Working pressure in the filter, depending on the type of installation, can range from optimal 2 bars up to maximum 10 bars.

Upon the request of the client, we make filters made of carbon (S235JRG2) or stainless (AISI 304, 316) steel. Carbon steel is sandblasted from inside and outside (using 2.5) and protected with a multi-layer epoxy covers (inner cover of 300 μm is allowed in food industry). Outer layer’s minimum thickness is 200 μm, a client can choose paints according to RAL. Inside the filter can be rubberized in acid-resistant “EBONIT” rubber E-10.10 thickness 4 mm with vulcanization in autoclave, and after this protection the filter can be used in installations for ozone disinfection and processes when the filing is regenerated by acids. Depending on the capacity, we produce filters in various dimensions.

Filters can be installed separately

or in series

5


Piping system can be made of steel (with epoxy protection or rubberized), PVC or various inox alloys.

MULTIMEDIA FILTERS: These filters are used to remove various materials in smaller concentrations in the same device. Besides removing suspended and colloidal particles; iron, manganese, etc. can also be removed by multimedia filters. Multimedia filters are not different in construction from the standard ones.

ACTIVATED CARBON FILTER: The good quality, activated carbon filter material applied, removes free chlorine and organic matters present in water, while water is flowing through the activated carbon filter bed. Impurities retained on the filter bed can be removed by backwash, the filter material loosened, and the charge be used further on.

Operating pressure min/max.: 3/8 bar

IRON AND MANGANESE REMOVAL FILTER: A high iron and manganese content causes discoloration of water. The transparent color of clean water turns reddish, but sediments may also be formed on the surfaces in contact with air. The equipment we offer prevents these adverse effects. For this undertaking, we use catalytic filter material, which can convert dissolved iron and manganese ions to substances insoluble in water. These compounds are easy to filter out from water. The precipitated flocks can be removed by means of backwash cycle.

6


According to filter material, MV Engineering GmbH & Co.KG offers two kinds of iron and manganese removal filters:

Greensand Plus Pyrolusite

MICROFILTRATION (PRE-FILTER): This process is used most often to block the penetration of mechanical and suspended particles to the surface of RO membrane. Cartridges with the porosity of 25, 10 or 5 µm are made as PP string wound or ,elt blown. Depending on the capacity, it may be conducted with one or more cartridges with a suitable length (10”, 20”, 30” and 40”). Depending on cleaning requirements, filter cartridges are periodically replaced with the new ones.

SOFTENER SYSTEMS: Softening is very often necessary in order to remove calcium and magnesium salts from raw water. The most common way is the use of a strong action ion exchange resin, which is regenerated with diluted commercial rock salt. We can offer a complete production program for water softening, starting from small capacities for household purposes to heavy duty industrial softeners. The operation of each installation could be manual or automatic. The regeneration could be time or quantity controlled. The filter vessel could be either GRP, carbon steel polyethylene coated or carbon steel epoxy painted. Filter vessel from stainless steel is available on request.

Duplex volume controlled water softener: The device is of continuous operation, so it is capable of providing soft water during regeneration, too. Therefore is suggested in the case of

8


fluctuating water withdrawal. The device starts regeneration cycle depending on water quantity having passed through, it means the system is volume controlled. (Regeneration starts automatically after the exhaustion of the resin column).

INDUSTRIAL WATER SOFTENERS : Completely automatic modular water softeners that can be installed in configurations of up to four units, capable of operating under every possible mode. Main features are: Electronic control for optimal operating cycle management, Counter-current regenerating for reducing salt and water consumption to a minimum, all operating parameters adjustable on-site by means of a user-friendly interactive programming system Up to 60 m³ /h in the four-unit configuration, "Peak Flow" patent for adjusting the number of units in operation depending on the flow when compensating wide variations in flow-rate (hotel applications, batch operations).

MEMBRANE FILTRATION SYSTEMS

9


In the water treatment, membrane filtration is the technique with lowest operation costs used to remove particles and salts in the water. For this area, MV Engineering GmbH & Co.KG offers multiple and high quality systems. Membrane filtration is a physical procedure for particle separation by means of semi-permeable membranes. There are 4 types of technologies, depending on the size of the particles/ molecules that are to be removed

Microfiltration Ultrafiltration Nano filtration Reverse osmosis

From these technologies, MV Engineering GmbH & Co.KG is specialized in plants for Ultrafiltration and Reverse osmosis. Our specialists with their detailed branch knowledge have not only the capacity to design the optimal plant for the particular application but also to provide the complete water treatment solutions.

The following overview shows the limits to the technologies:

ULTRA FILTRATION SYSTEMS

10


Due significant price reduction of UF module in last few years ultra filtration systems gain in popularity in water treatment plants as well as secure pretreatment for RO units.

Ultra filtration can work with raw (borehole) water, and still manage to filter 0,01 micron. Raw water must be free of Iron and manganesse (under MCL for drinking water).

Main characteristics of UF are bacteria and virus rejection (advantage to classic sand filtration), producing clear 0,1 NTU water (turbidity), low working pressure (1.5 - 2,5 bar).

Advantage over conventional systems are that this process can replace complete pretreatment (coagulation, flocculation and sedimentation) including filtration in one step, on much smaller foot print and to achieve better quality of of the water at the end.

REVERSE OSMOSIS SYSTEMS

11


Reverse Osmosis is the reversal of the natural osmosis process. This process is used to desalinate aqueous solutions. Using suitable high-performance membranes it is possible to remove more than 99% of all salts from an aqueous solution. Reversible osmosis (RO) uses semi-permeable membranes (permeates). Reversible osmosis is used in systems where a high quality of purified water is necessary to be obtained (pharmacy, electro-technology, chemo-dialysis, etc.) or e.g. when seawater is processed in order to produce potable water. In recent times, RO systems are widely used in purifying water from wells due to a more common contamination of ground and underground waters. The material membranes are made of mostly influences the quality of the water purified in the process of reversible osmosis. Breaking and clogging of permeates cause water contamination.

Advantages:

The process is continual (24/7) The process is isothermal, there are no phase changes of the fluid which is treated It has an extreme selectivity for certain elements, compounds and solutions Energy balance is very satisfactory especially in comparison with distillation procedure It is environmentally-friendly Maintenance costs are low The construction of the device is modular which enables expanding of the facilities

In RO module (membrane), the process is conducted so that water under pressure is brought onto the membrane, which lets out molecules of water and a small percentage of salt, while blocking dissolved salts. RO systems require a pretreatment that is determined depending on the quality of unprocessed water.

PUMP STATIONS

Booster pumps are designed to smooth out water pressure in areas where the flows are highly variable. This type of pumps is essential in water management systems and is used in a wide range of public and private settings. The booster pump itself is installed at the connection point between the water supply pipe and the primary building.The vast majority of booster pumps are installed in rural properties. Indoor plumbing works within a very simple, closed loop. The water is provided to the property from a main water management system. When a tap is turned on, vacuum pressure is created, pulling the water up along with the air. When the tap is turned off, the system is closed.In installations where the water flows are inconsistent, additional time is required to create sufficient pressure to pull the water up to the tap. This can result in excess pressure on pipes and connecting joints. When the water finally flows, it may include excess air, causing it to flow unevenly.There are two types of booster pumps: single stage and multiple stages. A single stage pump is attached to the end of the water supply pipe and can be repaired without affecting any other water delivery pipes. The entire process to install a single stage pump takes between three to five days, depending on the location and overall condition of the water pipes.

With an eye on the growing market for various types of pumps for different Industrial applications, has developed a wide range of Rugged, Reliable and Efficient Pumps for different applications. The range is continuously growing with additions to the product portfolio at regular intervals. Industrial Pumps from find applications not only in handling water but different types of fluids in Paper, Process and Pulp industries, Paint, Dyes and Chemical Industries, Mining and Metal Manufacturing Industries, Food & Beverage Industries, Textile industries, Power Industry, Machine Tool Industry apart from General Water supply. All the products can be customized to suit specific application and requirement and is backed by a dedicated State-of-the-Art Greenfield factory. All pumps are tested in a highly sophisticated PLC-SCADA based Test Bed complying with international standards.

DOSING SYSTEMS IN COOPERATION WITH ProMinent®

By the use of dosing systems, the dosing task becomes increasingly easier. Pre-mounted complete solutions made by MV Engineering GmbH & Co.KG are immediately available and ready for the use in important applications of dosage. Sensor technology, controllers and metering pumps form a unit with the necessary tanks and are ready for operation without installation work.

OZONE PLANTS IN COOPERATION WITH ProMinent®

Ozone has an extraordinarily large efficiency on killing microbes. Applied correctly, it has a very quick and efficient effect on almost all known bacteria, viruses and other microorganisms. Moreover, Ozone degrades to Oxygen and does not leave any by-products. Thus, it is a highly efficient and environmentally friendly mean of water

disinfection, as well as for removing Iron or Manganese traces from potable water.

UV SYSTEMS IN COOPERATION WITH ProMinent®

Ultraviolet (UV) water sterilization is based on a high sensitivity of microorganisms (bacteria, viruses, algae and their spores) to UV radiation with the wavelength of 254 nm. If it is used with sufficient intensity, UV light can ensure an excellent sterilization of water as it affects the DNA of microorganisms. This bio-structural disorder results in the incapability to reproduce which makes microorganisms harmless. With UV Plants, it is possible to have reliable and chemical-free water treatment for disinfection purposes and degradation of unwanted components. Easy installation, low maintenance and a variety of types, result in most economical projects for multiple

applications.

15


CHLORINE DIOXIDE IN WATER TREATMENT IN COOPERATION WITH ProMinent®

Chlorine dioxide is an extremely reactive gas, which – because of its instability – cannot be stored, and must only be produced in the required quantities in special plants on the site where it is to be used. Chlorine dioxide offers a number of advantages for water disinfection compared with chlorine, the disinfectant mainly used.

ELECTROLYSIS SYSTEMS IN COOPERATION WITH ProMinent®

Electrolysis is an economically sensible and technically perfected alternative to the dosing of sodium hypochlorite or other disinfectants. Chlorine, hydrogen and sodium hydroxide can be generated on site from harmless sodium chloride. The chlorine generated can either be dosed directly into the water as hypochlorous acid (HOCl) or temporarily stored with the sodium hydroxide generated as sodium hypochlorite (NaOCl).
