  • 1.Clarifier

    Clarifiers are used to remove suspended solids from raw water. Conventional clarifiers are circular in structure and require higher residence time and lesser velocity. This is an ideal choice for process industries with larger water requirement. Lamella type clarifiers are relatively new generation one which requires much lesser space because they can operate at higher velocity due to increased surface area. Lamella clarifier can be plate type or tube settler type. All the above range of clarifiers and are custom designed.

  • 10.cooling-water-treatment-chemicals-

    Common problem in cooling tower are three types Corrotion of metal surfaces could lead to contamination of fluids and has to avoided in heat exchanges condensers. Scaling – reduces the rate of heat transfering heat,exchanges heat or condenser considerably Biofouling will reduces cooling Capacity while fungal decay destroys structural integrity. The NACSO series prevents algae , fungal , and bacterial growth. Nasco offer a range of all the above products and are available in custom design cooling water treatment programs. Following are few of ours standard products.
