    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.

  • 17.membrane-bio-reactors

    The membrane bioreactor (MBR) is the combination of a membrane process like micro filtration or Ultra Filtration with a suspended growth bioreactor, and is now widely used for municipal and industrial waste water treatment with plants. The derived effluent is of high quality enough to be discharged to coastal, surface or brackish waterways or to be reclaimed for urban irrigation. Other advantages include small footprint, easy retrofit and upgrade of old wastewater treatment plants.

    Sewage treatment plants (STP) are waster water treatment plant using domestic waste instead of industrial. Domestic wastegenerated in Malls,Hospitals,Hotels, community centers,High Rise Buliding are not suppose to be let down the drain without confoomity to the statuary norms by environment regulation body.

    Many develop countries have Commen Effluent Treatment Plants (CETP’S) or Centralized Municipal Sewage Treatment Plant (CMSTP).But in many develop countries these are decentralized at client’s promises.We design,build and installs STP’S of different capabilities and different technologies.We are pioneenir in extended aerators technology and,We have  even recycled the treated waters for gardenings and makeup water for cooling tower.
    With our expertise in extended aerotion technology we deliver to our client various solutions,We have built STP’S with capabilities ranging from 25m3/day (Modular)) up to 1000m3/day.
