Product Description

Multilayer Sand Filter solids &turbidity Removal water treatment

Multi GradeFilter is used for removal of suspended solids &turbidity from Water & Wastewater. Our unique design of Multi Grade Sandfilter ensures the maximum utilization of the surface area, lesser pressure drop across the filter bed and effective removal of the impurities even under the conditions of high filtration rate compare to pressure sand filter & dual media filter. 

 

Working Principle:
Raw water is passed through the Multi grade media filter,contains anthracite at a top layer of media followed by fine & Coarse Garnet and quartz sand supported by pebbles and gravels. Multi grades of media and layers provide extra ordinary dirt holding capacity at various level of total media depth and produce unparalleled filter water quality.
During the filtration cycle the largest particles are strained out by the anthracite, coarse and fine sand, Coarse & fine garnet though a combination of adhesion and straining.  Since the particles in the water are filtered out at various depths in a multimedia filter, the filter does not clog as quickly as if all of the particles were all caught by the top layer.  



Benefits:
Efficient Turbidity and TSS Removal
High filtration rate
Filtration efficiency is up to 2.0 ppm suspended particles
Easy operation & maintenance
Wide range in material of construction
Economical way of production & design
Low Energy requirement
Can accommodate seasonal fluctuations in flow rate
Long filter cycles between backwashing with minimum loss of pressure. 
Application
Water treatment plant
Feed water of RO plant
Post treatment of wastewater treatment plant
Pretreatment of ion exchange based plant
Iron removal &Fluoride removal
Cooling tower water treatment plant.
Fountain, Water bodies and swimming pool
Rain water harvesting.
Gardening & washing application
River& lake water treatment.

 
 Most frequently used filtration fillings:
Fine gravel: 1-20mm
Silica sand of various roughness: 0.4-2.5mm
Active charcoal: is used for absorption of chlorine and other mineral substances
Anthracite: is used in two-layer or multi-layer filtration of drinking water in connection with sand - the addition of anthracite guarantees a longer filter lifetime, it facilitates a larger filtration through-flow and reduces sand contamination


The filtration bed can be formed by one layer or more layers of various filtration materials. Filtration sand lifetime during a proper washing of filters oscillates around 8 years on a standard basis.

Filters are controlled manually [with ball valves / shut-off valves] or automatically. In the case of an automatic filter control process, membrane or hydraulic or pneumatic valves are used.


The entire automatic process of filtration and back washing of filters is controlled by a central control unit. The control unit makes it possible to set filter washing on the basis of time, pressure difference or filtered water quantity.
 
Filters are washed, on a standard basis with raw water or with treated water from reservoirs.
 
Filters are fitted with a filtration inter-bottom with jets. The jets are made of the ABS material and make it possible to wash with water or both water and air. In the case of the filling height not exceeding 1500 mm, the water flushing process is fully sufficient.
 
Pressure filters are made of carbon steel with a protective anticorrosion coating with epoxy resin in the RAL 5010 [gentian blue] or 5012 [light blue] colour shade. The coating meets the conditions of hygienic harmlessness for contacts with drinking water.
