Automatic Backwash Quartz Sand Filter for Cooling Tower System
Automatic Backwash Bypass Sand Filter is consisted of a filtration system and a control system. Filtration system generally consists of the filter unit, three automatic valves, import and export pipeline, sewage pipeline. The filter unit includes a filter medium. Control system usually consists of PLC timing controller, differential pressure controller, and electromagnetic three-way valve.
Automatic Backwash Bypass Sand Filter is a high efficiency filter, It can effectively remove the suspended substance, microorganisms, and other fine particles in water. Ultimately achieve to reduce water turbidity, purify water quality.
Used in the treatment process, mainly for turbidity water treatment, reverse osmosis, and pretreatment preparation of ion exchange softening desalination system
Also used for sediment removal of surface water and underground water. Inlet turbidity less than 20 degrees, the outlet turbidity up to 3 degrees below.
It can be widely used in electronic power, petrochemical, metallurgy electroplating, paper textiles, pharmaceuticals dialysis, food and beverages, drinking water, factories and enterprises water, swimming pool. It also can meet the needs of liquid filtration in various industries
Advantages:
Multi-media carbon/sand filter tank in water treatment
A) High filtration efficiency.
B) Low resistance, high capacity, high sewage interception capability, long service life.
C) High cleanness of filter and no pollution of filtering media.
D) Anti acid-base.
E) High strength, high temperature resistant, no deformation.
F) Low purchasing cost and operation cost, easy to clean and replace filter cartridge.
G) Easy operating & maintenance
Working principle:
The filter is separated by filtration principle to the successful development of separation equipment, oil filter - special walnut shell filter media, walnut shell large specific surface area, strong adsorption, the characteristics of the large amount of sewage interception, removal of oil and suspended solids. The device has both automatic and manual control mode. Filter, the water flow from top to bottom, the water distributor, the filter layer, catchment, the filtering is done. Stirrer flip filter backwash water bottom-up, the filter thoroughly clean renewable.
