Rinse quartz sand filter forward and backward

Principle of Operation

The operation of continuous filter can be divided into two relatively independent and simultaneous processes: raw water filtration and filter material cleaning and regeneration. The two are completed in different positions of the same filter, the former power depends on the high position difference or pump lift, while the latter is completed by compressed air.

Quartz sand filter is the use of one or several filter media, normal temperature operation, acid and alkali resistance, oxidation, pH range is 2-13. The system is equipped with perfect protection device and monitoring instrument, and has backwash function, dirt and other pollutants are quickly washed away, less water consumption, according to user requirements can be set automatic function. Under certain pressure, make the stock solution through the medium contact flocculation, adsorption, interception, remove impurities, so as to achieve the purpose of filtration. Its internal packing is generally: quartz sand, anthracite, granular porous ceramics, manganese sand, etc., the user can choose to use according to the actual situation. The filtration accuracy is between 0.005 and 0.01m, which can effectively remove colloidal particles and macromolecular organic matter.

Activated carbon filter is mainly used for adsorption of free chlorine in water (adsorption power up to 99%), and has a high removal rate of organic matter and chroma. It is a pretreatment equipment for the process of making pure water by softening and desalting system. Filter media for activated carbon. The main material of the equipment is carbon steel anticorrosion, glass steel and stainless steel.

Function of product

Quartz sand filter is a filter filter material using quartz sand as a filler. It helps to remove impurities from the water. It also has the advantages of small filtration resistance, large specific surface area, strong acid and alkaline resistance, good pollution resistance, etc. The unique advantage of quartz sand filter is to realize the adaptive operation of the filter by optimizing the design of the filter material and filter. The filter material has a strong adaptability to the concentration of raw water, operating conditions, pre-disposal process, etc., that is, the filter bed automatically forms a dense state on the filter when filtering. It is beneficial to ensure the water quality under various operating conditions, and the filter material is fully dispersed when backwashing, and the cleaning effect is good. Sand filter can effectively remove suspended matter in water, and on the water colloid, iron, organic matter, pesticides, manganese, bacteria, viruses and other pollutants have an obvious removal effect. It has the advantages of fast filtration speed, high filtration accuracy and large sewage interception capacity. Mainly used in power, electronics, beverage, tap water, petroleum, chemical, metallurgy, textile, paper, food, swimming pool, municipal engineering and other process water, domestic water, recycling water and waste water depth disposal field.

Product Features

1, compact structure: the equipment set coagulation reaction, filtration, continuous cleaning in one. Simplified water treatment process, small footprint, simple structure, flexible installation and operation. The energy consumption and labor management cost of multiple links of raw water treatment process are reduced, and the difficulty of operation is reduced.

2. The coagulation reaction effect is obvious: the coagulation reaction mechanism and sedimentation mechanism can effectively remove the suspended matter and colloidal matter in the water, which is conducive to further lose the turbidity of the effluent in the sand filter area.

3, continuous self-cleaning filter: filter medium automatic cycle, continuous cleaning, no need to stop for backwashing.

4. Reduce the suspended matter (SS) content of raw water: with the micro-flocculation device, all kinds of industrial water, urban domestic sewage and industrial water with **SS≤mg/L as the reuse water, the removal rate is not less than 90%, to achieve the perfect filtration effect.

5, selected material, long service life.
