Features:
1. Filter tank is made of carbon steel with five layers' coating, so is absolutely corrosion free and weather resistant
2. With selected north American natural silica sand as filtering media, excellent for trapping suspended solid in circulation water
3. With specially designed backwash counting device
4. Control valves are connected to actuators directly, so no linkages are required, which eliminate all the problems caused by traditional linkage type control method.
5. With schedule 80 heavy duty PVC under-drain, strong and durable
Capacity range:
Available in 16 standard models with capacities from 3, 406 to 228, 487 liters

Applicable for:
Cooling tower systems, wastewater discharge, well water treatment, foods & beverage plants applications
Benefits:
1. Jr filter helps prevent cooling system fouling that results in emergency maintenance and downtime, and therefore maintains system's constant operation.
2. Jr filter enhances the effectiveness of water treatment program, and relatively reduces chemical-dosing cost
3. Jr filter reduces the buildup of deposits in cooling system, which maintains system efficiency and results in lower energy consumption
4. Jr filter eliminates the accumulation of scale and solid contaminates in cooling system, and so that minimizes the needs for cleanouts and maintenance with the function of evaporation, maximum volume of air contact with maximum surface area of water and the purpose to cool water is achieved. However, in the process of cooling the water, two effects appear:

1. Because of evaporation, the density of dissolved solid and density of electrolyte in water become higher and higher. That will cause scale formation and corrosion. In order to make up the evaporated water, the water fed in unavoidably brings contaminants as well.

2. A big volume of air is drafted into the cooling tower during operation. These air also bring dust, leaves, insect bodies^etc. These airborne contaminants are scrubbed by water and stay in the system water. It pollutes the circulation system such as cooling tower, pipe line and heat exchanger.
These two effects consist of four major water treatment problems those should be solved in the cooling tower circulation system:
Airborne contaminants biological fouling corrosion scale formation

Jr sand filter is a chemical free equipment so it won't cause secondary public nuisance. It perfectly matches the new trend of environmental protection. In the meantime, it solves those four major problems mentioned above.
