Product Features:

Quartz sand filtration is one of the effective means to remove suspended solids in water, and it is an important unit in advanced sewage treatment, sewage reuse and water supply treatment. Its function is to further remove the flocculated pollutants in the water. It achieves the purpose of water purification through the interception, sedimentation and adsorption of the filter material.

Scope of application:

1. Used in industrial water, domestic water and municipal water supply systems that require effluent turbidity ≤5mg/L to meet drinking water quality standards;

2. Removal of suspended solids and solids in industrial sewage;

3. It can be used as pretreatment equipment in ion exchange softening and desalination systems (reverse osmosis), coarse filtration equipment for industrial water supply that does not require high water quality; and used in swimming pool circulating treatment systems, cooling circulating water purification systems, etc. .

Features:

1. Unique multi-filter chamber structure can realize online backwashing (filtering, draining and backwashing at the same time).

2. Carbon steel or glass fiber reinforced plastic can be selected according to the water pressure of the system.

working principle:

The quartz sand filter uses quartz sand as the filter medium. The filter material has the remarkable advantages of high strength, long life, large processing flow, stable and reliable effluent quality. The function of quartz sand is mainly to remove suspended solids, colloids, sand, and rust in water. The water pump is used to pressurize, so that the raw water passes through the filter medium to remove suspended solids in the water, so as to achieve the purpose of filtration.
