carbon activated media filter for solid-liquid separation water treatment plant

Quartz sand filter(or Activated carbon filter)

Description:

Quartz sand filter is environmental protection field, deep treatment of sewage in qing dynasty the earliest, the most common application. Quartz sand filter to remove the water is the most effective means of suspended solids, is deep treatment of wastewater, sewage reuse and water treatment in the important unit, its effect is will the water has flocculation pollutants further removes it through the filter material, the interception and adsorption effect settlement and, to the purpose of water purification.
Quartz sand filter using quartz sand as the filter medium. The filter material has high strength, long life, water treatment, outlet water quality is stable and reliable, quartz sand the obvious advantages of the main functions are suspended in the water to remove, colloid, sediment, rust. The pump pressure, make the raw water through the filter medium, remove the suspended in the water, so as to achieve the purpose of the filtration.

working principle:

 1.By the entrance into the water, the first after thick mesh filter out larger particles, and then reach fine mesh impurities. In the filtering process, fine mesh gradually accumulated dirt and impurities in water, forming filtering impurities layer, because impurities accumulated in fine of filter layer, so in fine mesh medial side of internal and external form one differential pressure.
When filter pressure differential achieve default value, will begin to automatic cleaning process, during which no depletion, water supplies, clean room cleaning valves open and absorbing unclean device for internal pressure dropped substantially, suction filter canister and dirt by the pressure difference and suction pipe tube and rinsing room dirt between produced by suction nozzle, forming a suck a suction decontamination process. Meanwhile, electric motor drive sucked unclean tube along the axial do spiral movement. Suck unclean device axial movement and the combination of rotation movement within the entire mesh surface completely clean. The whole flushing process just tens of seconds. Drain valve closes in cleaning end. Filter began to prepare for the next flush cycle.

2. Processed by the water, the water enters the water entry in stainless steel mesh impurities deposition, the resulting differential pressure. Through the differential pressure switch monitoring in shuikou differential pressure changes, when the pressure difference control device to set value, to our hydraulic control valves, drive motor signals, cause the following actions: motor driving brushes spin, cleaning, and at the same time to filter for drainage, the control valve opened the cleaning process just continued dozens of seconds, when cleaning, shut off the valve end, motor stop, the system restore to its initial condition, began to enter the next filtration process.
Equipment installation, debugging by technicians, setting filtering time and cleaning conversion time, processed by the water enters the water entry, a filter began to work normally, when they reach the preset cleaning time, electric control device for hydraulic control valves, drive motor signals, cause the following actions: motor driving brushes spin, cleaning, and at the same time to filter for drainage, the control valve opened the cleaning process just continued dozens of seconds, when cleaning, shut off the valve end, motor stop, the system restore to its initial condition, began to enter the next filtration process.

Features:
simple structure, convenient operation and maintenance, operation can achieve automatic control, filtration efficiency high, small resistance, processing flow, fewer recoil. Widely used in pure water, food beverage water, mineral water and electronic, printing, dyeing, papermaking, chemical industry the pretreatment of the water quality and industrial sewage 2 level process after filter. Also used in water reuse system, swimming pool seawater treatment system depth filtration. for the industrial waste material also has good effect to remove. this kind of equipment is steel pressure type filter, can remove the raw material, the mechanical impurities and residual chlorine and chromaticity, press filter material, different mechanical filter are divided into single, double, three layer filter material and fine sand filter; Quartz sand filter material generally as a single layer quartz sand, particle size of 0.8 ~ 1.2 mm, filter height is 0.9 ~ 1.2 m usually. According to the structure and divided into the single flow, double river, vertical, horizontal; According to the inside surface corrosion request, and divided into line with rubber type and the rubber lining type.
