Water filtration for industrial water, wastewater and water recyling processes

 


 

Sand Filter (SF)

Sand filtration is frequently used and very robust method to remove suspended solids from water. The filtration medium consists of a multiple layer of high silica 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. A special application of a sand filter is the removal of iron in surface and ground or well water. An iron removal installation consists of a aeration to oxidise and precipitate the iron and manganese, followed by removal of the precipitated particles with the sand filter. During service Water enters from the top, travels through the filtering media & goes out from the bottom. The suspended solids in the water get trapped in the filter & we get clean clear water at the outlet. This accumulated dirt (suspended solids) needs to be removed otherwise the filter will get choked & will result in less treatment flow, damage to the filter, damage to the pump, etc. The cleaning operation of the filter is called Backwash. This backwash operation needs to done once the differential pressure across the filter reaches 0.8 kg/cm2 or 24 hours of service cycle whichever is earlier. 

FRP Body with Multi-port valve Filtration Systems:Flow range - 1 m3/hour to 16 m3/hour. Carbon steel (Epoxy-coated) Body with C.I. valves Filtration Systems:Flow range - 7 m3/hour to 250 m3/hour.

     

Duel Media Filter (DMF)

During service Water enters from the top, travels through the filtering media & goes out from the bottom. The suspended solids in the water get trapped in the filter & we get clean clear water at the outlet.

This backwash operation needs to done once the differential pressure across the filter reaches 0.8 kg/cm2 or 24 hours of service cycle whichever is earlier. FRP Body with Multi-port valve Dual Media Filtration Systems:Flow range - 1 m3/hour to 16 m3/hour. Carbon steel (Epoxy-coated) Body with C.I. valves Dual Media Filtration Systems:Flow range - 7 m3/hour to 250 m3/hour.

Activated Carbon Filter 

 

Ancient civilizations knew the benefites of charred coal for improving the quality of drinking water. Today also we rely on the same principle and being used in numerous applications, is activated carbon.

Activated carbon (AC) filtration is most effective in removing organic contaminants from water. Organic substances are composed of two basic elements, carbon and hydrogen. Because organic chemicals are often responsible for taste, odor, and color problems, AC filtration can generally be used to improve aesthetically objectional water. AC filtration will also remove chlorine. AC filtration is recognized by the Water Quality Association as an acceptable method to maintain certain drinking water contaminants within the limits

Activated carbon applications

Drinking water treatment
  • decolourisation of sugar and sweeteners
  • gold recovery
  • production of pharmaceuticals and fine chemicals
  • catalytic processes
  • off gas treatment of waste incinerators
  • automotive vapour filters
  • colour/odour correction in wines and fruit juices, etc.
