Filtration

Nass Tech provides design & construction of different types of filtration systems with material of construction poly glass, epoxy coated steel or stainless steel, with manual or automatic control.

Filtration systems can be used as separated solution or as a part of pretreatment of reverse osmosis (RO) systems.

Design of Filtration system depends on chemical analysis of raw water.

 

 

  • Multimedia Filter

Multimedia filter is the most common filtration system used to remove suspended solids & turbidity.

Multimedia filter contain fine sand which is coupled with course gravel support bed, also anthracite can be used in the presence of silt in water.

    • Activated Carbon Filter

    Activated carbon media is recommended for the removal of unpleasant tastes, odor, COD, free chlorine and organic matters by the mean of adsorption mechanism.

  • Birm Filter

Birm media is an efficient and economical media for reduction of dissolved iron from water supplies if present in low concentrations with using of oxidizing agent prior to filter instead of regeneration chemicals.

 

 

  • Green Sand Filters

Green sand media is capable of reduction iron, manganese and hydrogen sulfide from water by the action of oxidation and filtration, media is regenerated by strong oxidizing agent as Potassium Permanganate or Chlorine.

 

  • Self Cleaning Filters

Self cleaning filters operates online as water passes through the filter, the dirt particles are collected on the screen, this causes a drop in pressure, when pressure drop reaches certain value, the cleaning cycle is initiated and the vacuum screen cleaner aggressively suctions the dirt from inside of the screen and flushes it out to the drain, the back wash process is done in few seconds without interruption of main flow.

Body material is available as stainless steel, GRP or PVC.

Self cleaning filter has advantages from multimedia filter with smaller area & better quality of filtration.

 

  • Ultra Filtration

Ultra filtration provides macro-molecular separation up to 0.1 micron for suspended solids, colloids, proteins, microbiological contaminants and large organic molecules.

UF plants are built from hollow fiber membranes in UPVC housings

 

  • All systems are available as a container solution for cost reduction and to e ready for operation.
