The pressure filter available in Standard plant range are two basic types, in terms of the filter media. Filter is available with either graded sand as the media. Depending on individual merits, either one or a combination of can be used for a particular water.
The pressure filter comprises of a FRP pressure vessel containing the media, provided externally with a valve and piping to direct and control flow of water during treatment and for cleaning. The media is supported by layers of crushed silex of specific size.
The vessel is provided with inlet and outlet strainers for distribution / uniform collection. This strainer will ensure even distribution across the surface of the filter bed, to control and measure flow during normal and cleaning operations, flow indicators are provided at optional cost. Pressure gauges is provided at the inlet to measure inlet pressure.
The pressure filter with sand as media uses sand of two, different, carefully selected sizes mixed intimately together. Unlike conventional sand filter using a single grade of sand, this special media permits flow velocities nearly three times those used in conventional filter. This filter is called Multigrade Filter.
The activated carbon filter is used to de-chlorinate raw water has been chlorinated and also same times for removal of organic impurities. Depending on the suspended matter content in the water to be filtered, it can be used either by itself or following a sand filter.
Pressure Sand Filters System
Pressure Sand Filter used in waste water treatment plant remove non ionic impurities like clay, turbidity, dust, particles, heavy metals suspended solid matter etc. from water & wastewater. In pressure sand filter generally quartz sand is used for filtration supporting with gravels &pebbles ideal for sediment turbidity, sand, clay etc.
Our simple but well-engineered media based filter acclaims stringent design, High performance , less pressure drop across the bed, longevity, optimum utilization of surface area ensure us to gain more and more clients' satisfaction..
Working Principle
In a Pressure Sand Filter, water is passed through multi layers of filter media consisting graded sand, pebbles and gravels layers. The contaminants in the water are captured in the media bed and filtered water passes into the discharge manifold at the bottom of the tanks. The next and last step is backwashing, a process of effectively removal of captured contaminants from the media bed. After back-washing the filter is rinsed with raw water and after the required quality of water is achieved the filter is put back into service.

For the purpose of a proper removal of these substances from water and to obtain the requested quality of output water it is necessary to propose a suitable filtration process. The actual filtration through pressure filters is complemented with aeration, clarification, coagulation, static mixers, disinfection. The kind of the filtration medium used is very important as well.
Multi Grade Sand Filter
The Multigrade Sand Filter is a depth filter that makes use of coarse and fine media mixed together in a fixed proportion. This arrangement produces a filter bed with adequate pore dimensions for retaining both large and small suspended particles. Multigrade sand filter is highly recommended for the removal of suspended solids & un-dissolved impurities like dust particles & heavy metals etc. doing so it reduces turbidity. Pressure Sand Filter is an ideal solution for the systems with high sediment, silt, sand, and turbidity. Our Sand filters are well established in media filtration technology. The sand filters are specially designed to take care of the range of suspended impurities. Chemtronics filtration series multigrade sand filter include vessel complete with piping & valves sand media and gravel support bed.

- • Filtration in Tertiary waste water treatment.
- • Pharmaceutical Production processes.
Activated Carbon Filters
Activated carbon filters are generally employed in the process of removing organic compounds and/or extracting free chlorine from water, thereby making the water suitable for discharge or use in manufacturing processes. Eliminating organics in potable water, such as humic and fulvic acid, prevents chlorine in the water from chemically reacting with the acids and forming trihalomethanes, a class of known carcinogens.
Activated Carbon (AC) filtration, as with any water treatment method, is not capable of removing every possible type of contaminant. For example, sodium, microbes, fluoride, and nitrates cannot be removed with AC filtration. Water softening also cannot be achieved with AC filters. In addition, heavy metals, such as lead, can only be removed with a very specific kind of activated carbon water treatment, which is typically used only in residential point-of-use filters.
Uses and Application
We are manufacturers, suppliers of Activated Carbon Filter. The benefits of using this filter include the ability to filter out a wide range of contaminants and the fact that they can be reused over time. They are also used in industries such as steel, paper, petroleum refining, and chemical manufacturing for a variety of applications such as air purification, water treatment, air filtration, and industrial processes.
