Mechanical filter related products is introduced

Quartz sand filter, activated carbon filter, many media filters, manganese sand filter collectively known as mechanical filter, mainly through the filler to make mechanical filter, made of carbon steel and stainless steel material, mechanical filter often and dosing system, activated carbon filter, bag filter, precision filter, is the earliest environmental cleaning, sewage depth processing, one of the most common. Quartz sand filter is the most effective means of removal of suspended solids in water, sewage water supply, wastewater recycling and processing is important in the unit, its role is to further remove have flocculating pollutants in water, it through the interception of filter material, settlement and adsorption, achieve the goal of the water. A, mechanical filter characteristics:

the device has simple structure, convenient operation and maintenance, and can realize automatic control, high filtration efficiency, small resistance, processing flow, fewer back flush. Widely used in pure water, food, drinking water, mineral water and electronics, printing and dyeing, paper making, chemical industry, water quality of pretreatment and filtering after secondary treatment of industrial wastewater. Also used for water reuse system filtering, the depth of the swimming pool circulating water treatment system. For suspended solids in the industrial waste water also has a good removal efficiency.

this is a steel pressure filter, such equipment can remove the suspended matter in raw water, mechanical impurity, residual chlorine and chromaticity, according to the filter material, mechanical filter are divided into single, double, three layers of filter material and fine sand filter; Quartz sand filter for single-layer commonly quartz sand, particle size of 0. 8 to 1. 2 mm filter layer height, usually 1. 0 to 1. 2m。 According to the structure is divided into a single stream, shuangliu, vertical and horizontal; According to the requirements of inner surface corrosion to divided into type line with rubber and rubber lining.

2, mechanical filter, debugging and installation

1, at the time of loading of quartz sand, the tightness of the filter cap, must be carefully checked to ensure that every fastening and correct rear can fill in quartz sand filter cap;

2, pressure filter based on the concrete construction, should press filter supporting feet reserved hole hole position, and after the foundation to meet the design strength for lifting and connecting pipe assembly of the filter.

3, filters run early, should according to the local water quality situation gradually grope for operating experience, to identify the varieties and dosage of coagulant, backwash drainage gate valve opening and so on.

4, during the running of the filter, the water turbidity shall not be higher than the design index, and backwash according to design requirements, otherwise it will cause operation cycle of the shortened or filter layer a mud ball, serious when affect water quality.

5, direct filtration, the coagulant should be prepared with a certain concentration, and dosing prior to the mechanical filter. Such as activated carbon filter and bag filter, precision filter commonly placed in the front of it.

6, flush steps:

a. Wash: shut down into the water pump inflow gate, open the drain valve, according to the design requirements of washing strength and flushing time back flush.

b。 Resume: the closed drainage gate, open the inlet valve and bleed valve, launch into the water pump, air in the filter, ruled out entirely, and then close the discharge valve, filter that is back to normal operation.

7, when a few pressure filters run in parallel, the in and out of the water pipe shall be installed to control the valve.

our company is specialized in producing all kinds of mechanical filter manufacturers, affordable, welcomed the purchase.
