Quartz sand filter
(1) Equipment Introduction
Quartz sand filter, also known as shallow medium filter, is an efficient filtration device that uses quartz sand as a filtering medium to filter water with high turbidity through a certain thickness of granular or non granular quartz sand under a certain pressure. It effectively intercepts and removes suspended solids, organic matter, colloidal particles, microorganisms, chlorine, odors, and some heavy metal ions in the water, achieving the effect of reducing water turbidity and purifying water quality.

(3) Structural principle
The working process of a filter can be divided into three stages: filtration, backwashing, and forward washing. Filtration is when raw water enters the filter through the inlet pipe, and the upper water filter evenly distributes the water on the upper part of the filter layer. The filtered purified water flows out through the outlet pipe. As the filtration progresses, more and more pollutants are intercepted in the filter layer, and the head loss also increases. In order to ensure the quality of the effluent water, the filter layer must be cleaned. During backwashing, water enters the lower part of the filter, and the lower water filter evenly distributes the water on the lower part of the filter. The pressurized water slowly lifts the filter layer. At this time, the filter material particles rub and collide with each other, so that the filter material is washed clean. The backwashed sewage is discharged from the sewage pipe. After backwashing, the filter material needs to be washed forward. The sewage is discharged from the sewage pipe, and after washing, the filter enters the next cycle of filtration. Regeneration can be achieved through regular backwashing, and the operation, backwashing, forward washing, and operation of the filter are completed by opening and closing the relevant gates.
(4) Working principle
1、 The operation of high-efficiency continuous filters can be divided into two relatively independent yet simultaneous processes: raw water filtration and filter material cleaning and regeneration. The two are completed at different positions within the same filter, with the former relying on high differential or pump lift for power, while the latter is accomplished through compressed air.
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, with a pH range of 2-13. The system is equipped with complete protection devices and monitoring instruments, and has a backwash function. Mud 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 passed through the medium for coagulation, adsorption, and retention 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 filtration accuracy is below 150 mesh, which can effectively remove colloidal particles and high molecular organic matter, and is used to remove suspended solids in water.
Activated carbon filters are mainly used to adsorb free chlorine in water and have high removal rates for organic matter and color. 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.
