WATER FILTRATION PLANTS

PRE & POST WATER FILTRATION

With certain water parameters, an essential aspect of effective contaminant removal is pre-treatment of the raw water before reaching the primary system. This is true whether the application is for potable water, commercial, industrial, or environmental. Without a proper understanding of the water chemistry and parameters that affect system performance, whether it is a media or membrane system, high operational costs or non-performance will result.

Pre-treatment can be simple mechanical filtration for suspended solids, coagulation or dispersant chemical addition, chlorine or other oxidation chemical addition or removal, and/or removal of organics or other contaminants that can foul or otherwise diminish system performance and require costly operation and maintenance.

Depending on the application, such as for potable water, the treated effluent may require pH correction or disinfection prior to the distribution. Ad Edge offers a variety of post-treatment system modules for chlorination, pH adjustment and others which may be desirable to achieve final water quality.

Sand filtration is frequently used and very robust method to remove suspended solids from water. The filtration medium consists of a multiple layer of sand with a variety in size and specific gravity. Sand filters can be supplied in different sizes and materials both hand operated or fully automatically.


Raw water pump is used for generating necessary operating pressure in the pressure sand filter. Raw water is passed through CHEMTRONICS Multigrade Sand Filter at a pressure of 3.5 kg / cm2 to reduce the suspended solids present in the raw water.

The filter will effectively remove up to 30 – 50 micron of the suspended solids to less then 5 ppm. The filter will have to be washed with raw water for 20 to 30 minutes daily. To filter the partials below 30 – 50 micron cartridge filter is used.

Applications for sand filtration :


• Preparation of cooling water
• Treatment of waste water
• Production of drinking water
• Filtration in swimming pools
• Pre filtration for membrane systems
• Filtration of gray or surface water

• Swimming pool water

IRON REMOVAL PLANTWe are the largest manufacturer of Iron Removal Plants, reputed in Private, Govt. and various Industrial sectors at an amazingly low cost iron removal plants chennai. Hope you know that: Iron present in ground water is responsible for imparting a reddish colour to the water. An abnormal accumulation of iron content in parenchyma organs can cause diseases like hemochromatosis and other such gastrointestinal diseases. Moreover, iron contaminated water acquires a metallic taste and is harmful to drink iron removal plants Coimbatore.You should come to us because:Our specially designed Iron Removal Plants (IRP)s can remove metals and chemical contamination up to 12PPM. Our Iron Removal Plants are provided with highly adsorptive filters to trap even the last trace of iron content in water and thereby rendering clean and healthy water.

Ultrafiltration (UF) is a type of membrane filtration in which hydrostatic pressure forces a liquid against a semipermeable membrane. A semipermeable membrane is a thin layer of material capable of separating substances when a driving force is applied across the membrane. Once considered a viable technology only for desalination, membrane processes are increasingly employed for removal of bacteria and other microorganisms, particulate material, and natural organic material, which can impart color, tastes, and odors to the water and react with disinfectants to form disinfection byproducts (DBP). As advancements are made in membrane production and module design, capital and operating costs continue to decline.Ultrafiltration uses hollow fibers of membrane material and the feed water flows either inside the shell, or in the lumen of the fibers. Suspended solids and solutes of high molecular weight are retained, while water and low molecular weight solutes pass through the membrane. This separation process is used in industry and research for purifying and concentrating macromolecular (103 - 106 Da) solutions, especially protein solutions. Ultrafiltration is not fundamentally different from reverse osmosis, microfiltration or nanofiltration, except in terms of the size of the molecules it retains. When strategically combined with other purification technologies in a complete water system, UF is ideal for the removal of colloids, proteins, bacteria, pyrogens, proteins, and macromolecules larger than the membrane pore size from water. The primary removal mechanism is size exclusion, though surface chemistry of the particles or the membrane may affect the purification efficiency. UF can be used as pretreatment for reverse osmosis systems or as a final filtration stage for deionized water.The primary advantages of low-pressure UF membrane processes compared with conventional clarification and disinfection (post chlorination) processes are:No need for chemicals (coagulants, flocculates, disinfectants, pH adjustment);Size-exclusion filtration as opposed to media depth filtration;Good and constant quality of the treated water in terms of particle and microbial removal;Process and plant compactness; andSimple automation.  Brand/make:GE / HYDRANAUTICS / DOWModel/Type:ULTRA PRESSURIZED FILTRATIONInstallation Service:Yes

ACTIVATED CARBON FILTERACTIVATED CARBON FILTER Media Filters contain several types of media and gravel under bedding. Multi-media filtration is a proven design concept; the coarse media layers in the top of the tank trap large particles, and successively smaller particles are trapped in the finer layers of media deeper in the bed The result is a highly efficient filtering since removal takes place throughout the entire bed. Multi-Media depth filters typically remove particles 5-15 microns in size or larger. All media included in our filters are carefully selected according to particle size, so the media retains its stratification during backwash and rinse. Automatic backwashing system removes the trapped contaminants within the filter bed and washes them down the drain.#TypesSpecification1Available Flow Rates750/1000/1500/2000/3000 Litres/Hour2MakeFRP (fibre-reinforced polymer)3ValveMultiport valve, Make: GF-ABS4Flow ModeDown Flow5Filtration Stages4 layes (Graded Quartz Sand, FIne white sand, Activated Carbon granules- IV 950gms, Pebbles)6SystemSemi-automatic / Fully Automatic
