The quartz sand filter tank used in chemical plants utilizes the refined quartz sand filter material filled in the tank, which is mainly used for water treatment to remove turbidity, soften water, electrodialysis, reverse osmosis pre-treatment, and can also be used for surface water, groundwater, and other aspects. It can effectively remove suspended solids, organic matter, colloids, sediment, etc. from water.

OneWorking principle of quartz sand filter tank for chemical plants

Quartz sand filter is a filter that uses one or several filtering media, operates at room temperature, is resistant to acid and alkali, and oxidizes,PHThe scope of application is2-13The system is equipped with complete protection devices and monitoring instruments, and has a backwash function. Dirt and other pollutants are quickly washed away, with low water consumption. The fully automatic function can be set according to user requirements. Under a certain pressure, the original liquid is subjected to coagulation, adsorption, and retention through the medium to remove impurities, thereby achieving the purpose of filtration. The fillers inside are generally quartz sand, anthracite, granular porous ceramics, manganese sand, etc. Users can choose to use them according to their actual situation. Its filtering accuracy is0.005-0.01mBetween them, it can effectively remove colloidal particles and high molecular organic matter.

Mainly used to remove suspended solids in water. This device, in conjunction with other water treatment equipment, is widely used in various water treatment projects such as water purification, circulating water purification, and sewage treatment.

Filters are mainly used to adsorb free chlorine in water(Adsorption force reaches99%)It also has a high removal rate for organic matter and chromaticity. It is a pretreatment equipment for the pure water production process of softening and desalination systems. The filter material is activated carbon. The main materials of the equipment are anti-corrosion carbon steel, fiberglass, stainless steel, etc.

TwoApplicable conditions for quartz sand filter tanks used in chemical plants

Quartz sand filter is suitable for requiring filtered water turbidity ≤3milligram/Upgrade water supply facilities for industrial, rural, urban, and residential areas. The double-layer filter material filter is used for direct filtration, and the influent turbidity is often maintained at60milligram/Under the condition of adding coagulant before filtration, if the concentration is below the required level. When used for sedimentation filtration, the influent turbidity is ≤15milligram/Raise. Single layer filter material filter is only suitable for inlet turbidity ≥15milligram/Filter the sediment water. The filter has a simple structure and is easy to operate. When the suspended solids content in the raw water is less than30～50mg/LWhen used, it can be used for ion exchange softening(Or desalination)Pre treatment equipment for the process.

ThreeThe role of quartz sand filtration tank in chemical plants

Quartz sand filter is a pressure filter that uses refined quartz sand filter material filled in the filter. When the incoming water flows through the filter layer from top to bottom, suspended solids and viscous particles in the water are removed, thereby reducing the turbidity of the water.

Mainly used for pre-treatment of turbidity removal, softened water, electrodialysis, reverse osmosis, and can also be used for surface water, groundwater, and other aspects. It can effectively remove suspended solids, organic matter, colloids, sediment, etc. from water.

Quartz sand filters can be widely used in electronic power, petrochemical, metallurgical electroplating, papermaking and textile, pharmaceutical dialysis, food and beverage, drinking water, factory and enterprise water, swimming pools, etc. Can meet the liquid filtration needs of various industries.

FourInstallation and operation of quartz sand filters for chemical plants

　　1When filling quartz sand, it is necessary to carefully check the tightness of the filter caps to ensure that each cap is securely fastened before filling quartz sand.

　　2When constructing on the concrete foundation of the pressure filter, holes should be reserved according to the position of the filter foot holes, and the filter should be lifted and connected to the pipe assembly after the foundation reaches the design strength.

　　3During the initial operation of the filter, the operating experience should be gradually explored based on the local water quality situation to determine the type and dosage of coagulant, as well as the opening degree of the drainage gate valve during backwashing.

　　4During the operation of the filter, the turbidity of the incoming water must not exceed the design specifications, and backwashing must be carried out according to the design requirements. Otherwise, it may shorten the operating cycle or form mud balls in the filter layer, which can seriously affect the quality of the effluent.

　　5When directly filtering, the coagulant should be prepared at a certain concentration and added before the pump.

　　6When quartz sand filters are operated in parallel in chemical plants, gate valves should be installed on both the inlet and outlet pipes.
