Treatment of high concentration starch wastewater with automatic filter


With the development of starch industry technology, the process of treating starch wastewater has also made great progress in water saving. One kind of water treatment equipment called automatic filter has attracted extensive attention.

The full-automatic filter is a precision equipment that uses the filter screen to directly intercept impurities in the water, remove suspended solids and particles in the water, reduce turbidity, purify water quality and reduce the generation of system dirt, bacteria, algae and rust, so as to purify water quality and protect the normal operation of other equipment in the system. Water enters the full-automatic filter body from the water inlet. Due to the intelligent (PLC, PAC) design, The system can automatically identify the degree of impurity deposition and send a signal to the blowdown valve for automatic blowdown.

Full automatic filter, operation and control, full-automatic filter and automatic sewage discharge without external energy. During backwashing, there is continuous flow, and the cleaning and filtration cycle can be adjusted. The cleaning and filtration time is 10-60 / s by default, and the water loss from cleaning and filtration accounts for only 0.001% – 0.002% of the filtered water; The filtration accuracy can reach 2-200 microns; The working pressure can reach 0.15-1.00mpa; Single set flow: 4-600m / h. It can be installed vertically, horizontally, and inversely in any direction and position. It can be used for water filtration in industry, agriculture, municipal power, electronics, medicine, food, printing and dyeing, construction, iron and steel, metallurgy, papermaking and other industries.

The actual operation results show that it is feasible to use the automatic filter water treatment process to treat high concentration starch wastewater, and the effluent quality can meet the national standard.
