Overview of Multi-media Filters

A multi-media filter is a process that uses one or several filtering media to pass water with high turbidity through a certain thickness of granular or non-granular materials under a certain pressure, effectively removing suspended impurities and clarifying the water. Commonly used filter materials include quartz sand, anthracite, manganese sand, etc. It is mainly used for water treatment to remove turbidity, soften water, and as a pre-treatment for pure water, etc. The turbidity of the effluent can reach3Below degrees. Multi-media filters are commonly used pretreatment devices for deep water purification, and different filter materials can be added according to process requirements.

Quartz sand filtration function

The quartz sand filter is a type of filter that uses quartz sand as the filter material. It is beneficial for removing impurities from water. It also has the advantages of low filtration resistance, large specific surface area, strong acid and alkali resistance, and good anti-pollution performance. The advantage of quartz sand filters lies in the fact that by optimizing the design of filter materials and filters, the self-adaptive operation of the filter is achieved. The filter materials have strong self-adaptability to the concentration of raw water, operating conditions, and pretreatment processes, that is, during filtration, the filter bed automatically forms a state of being looser at the top and denser at the bottom. It is conducive to ensuring the effluent quality under various operating conditions. During backwashing, the filter material is fully dispersed, resulting in a good cleaning effect. Sand filters can effectively remove suspended solids from water and have a significant effect on removing colloids, iron, organic matter, manganese, viruses and other pollutants in water. It also has the advantages of fast filtration speed, high filtration accuracy and large dirt-holding capacity. It is mainly used in various fields such as power, electronics, beverages, tap water, petroleum, chemical engineering, metallurgy, textile, papermaking, swimming pools, municipal engineering, etc., for the advanced treatment of process water, domestic water, circulating water and wastewater.

Features of quartz sand filters

The quartz sand filter equipment features a simple structure, automatic operation control, large processing flow, few backwashing times, high filtration efficiency, low resistance, and convenient operation and maintenance. This product can be divided into manual type and fully automatic type. The manual type mainly controls the operation, forward washing and backwashing of the filter through the adjustment of valves;The fully automatic type controls the operation of the filter, forward washing, backwashing and other states through an automatic head. The tank material can be divided into fiberglass reinforced plastic tank, carbon steel tank and stainless steel tank, and can also be made according to the user's requirements.
