The Multigrade Filter or Pressurised Sand Filter is a depth filter that makes use of graded sand media of various sizes 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 filter is highly recommended for the removal of suspended solids & un-dissolved impurities like dust particles & heavy metals etc. up to 50 micron.
Our sand filters are specially designed to take care of the range of suspended impurities.
Multigrade Filter is comprises of MS /SS / FRP Pressure Vessel, Frontal piping wok with manual / Automatic multi-port valve butterfly valve / conventional valves for easy operation and control. Available from 1,000 Litres per hour to 5,00,000 Litres per hour.
