Mechanical filters are also called pressure filters. It is an important part of the pre-processing and water purification system for pure water preparation. Made of steel rubber or stainless steel, it is divided into natural quartz sand filter, multi-media filter, activated carbon filter and manganese sand filter according to different filter media. It can be divided into single-flow filter according to the water inlet method. Double-flow filter, according to the actual situation can be used in conjunction can also be used alone. The single-flow mechanical filter has a simple pipe and runs smoothly. The filtration flow rate is generally 4-50 m/n, and the operation cycle is generally 8 hours. The two-flow type mechanical filter is provided with a water inlet device at the upper and lower ends and a water outlet device at the middle portion. Its advantages are large amount of filtered water, high decontamination capacity and long operating cycle, generally 20 hours. The disadvantages are that the pipeline system is more complex and the operation is not stable, and it is difficult to flush and refuel.

Mechanical filtration is widely used in water treatment processes. It is mainly used for water treatment to remove turbidity, reverse osmosis, and ion exchange softening and desalinization system pre-treatment, and can also be used for surface water and groundwater removal of sediment. The influent turbidity requirement is less than 20 degrees, and the effluent turbidity can reach 3 degrees or less.

Mechanical filter, which feeds raw water into a mechanical filter equipped with quartz sand at all levels, using quartz sand interception capacity, can effectively remove large particles suspended in water and colloids, etc., so that the turbidity of the water is less than 1mg/l, to ensure the normal operation of subsequent processing.

The raw water is fed with a flocculating agent in the pipeline. The flocculating agent undergoes ion hydrolysis and polymerization in the water. The colloidal particles in the water strongly adsorb various products of hydrolysis and aggregation, so that the surface charge and diffusion thickness of the particles are simultaneously reduced, and thus the particles are mutually exclusive. Can reduce, close to each other and agglomerate. When the polymer produced by hydrolysis is adsorbed by two or more colloids, bridges are formed between the particles to form a larger floc, and when the mechanical filter is passed, the sand filter is retained. .
