Product Details:

These filters are the most popular method for removal of turbidity from water. The Pressure Sand Filter consists of a multiple layer of sand with a variety in size and specific gravity. These Filters are designed to remove turbidity and suspended particles present in the feed water with minimum pressure drop. These Filters are custom designed to suit the process requirement. These filters are offered in Mild Steel, FRP or SS construction with face piping and associated Valves.

Construction

The Pressure sand filter consists of a pressure vessel either vertical or horizontal, with a set of frontal pipe work and valves, graded silica quartz sand supported by layers of graded under bed consisting of pebbles and gravels, a top distributor to distribute the incoming water uniformly throughout the cross section of the filter, and an under drain system to uniformly collect the filtered water.

Process

Raw water flows down wards through the filter bed and as the suspended matter, which is treated by addition of a coagulant like alum or poly electrolyte, is retained on the sand surface and between the sand grains immediately below the surface. There is steady rise in the loss of head over a period of time and the flow reduces once the pressure drop across the filter is excessive.

The filter is then taken out of service and cleaning of the filter media is effected by flow reversal also called as backwash. To assist in cleaning the bed, the backwash operation is sometimes preceded by air scouring by way of agitation through the under drain system. The air scouring agitates the sand with a scrubbing action, which loosens the intercepted particles. The filter is now ready to be put back into service.

Product Details:

This Ultraviolet (UV) technology is a non-chemical water and wastewater treatment system that offers utilities and industrial facilities a safe and proven alternative to chemicals for the effective treatment of bacteria, microorganisms, and viruses or chemical decomposition in fresh water, brackish water, or seawater.

All HOD UV systems feature proprietary medium pressure (MP) UV lamps that provide a broad germicidal spectrum of polychromatic UV light (200-320 nm). MP lamps effectively inactivate and prevent the recovery of a wide range of bacteria, microorganisms and viruses  and hope will help fulfill your Ultra-Pure water requirements.

Advantages:

1.  Cost effective in CAPAX & OPEX

2.  Tailor made solution

3.  Min Electrical consumption

4.  Min and easy maintenance -no “shut down” time

5.  The system adjust itself as per water conditions (flow, UVT).

6.  Min. area of installation

A sand-anthracite filter or dual media filter/multi-media filter is primarily used for the removal of turbidity and suspended solids as low as 10-20 microns. Dual media filters provide very efficient particle removal under the conditions of high filtration rate.

A Dual/Multi Media Filter is used to reduce the level of suspended solids (turbidity) in incoming feed water.

Water in a dual media filter passes through media with moderately smaller pores. Anthracite exudes out the largest molecules. Next layer removes particles with the help of adhesion and straining combination feature of sand and garnet. Filters do not block as fast as they do in a single filtration process. It is basically due to multiple depths or filters in dual media filter process.

A back washing technique is used in dual media filters that helps maintaining unit efficiency.

Dual filters are more efficient than the normal sand media filters in attracting large amount of particles present in water. This happens because of the many filter layers with different levels of pores.

Another difference noted when compared with the sand media filters is that dual media filters last longer. This is because of the complete utilization of the dual media filter bed. Some more benefits are mentioned below:

 

• Removes turbidity and TSS effectively
• High quality output
• Hand holes and two elliptical manholes
• High dirt removal capacity
• Filtration rate is high
• Easy operation
• Easy to maintain
• Easy to install
• Low installation cost
• Reliable and efficient
• Low energy requirement
• Minimal start-up time
• Loss of pressure is less
• Cost effective

Activated Carbon Filter are designed to remove free chlorine, organic matter, odour and Colour present in the raw water and waste water.

Due to its high degree of micro porosity, activated carbons provide a huge surface area. Activated carbon filter operates through adsorption. Adsorption is directly related to the surface area of the media. This great surface area furnishes a huge adsorption area for organic as well as chlorine molecules to attach themselves.
