Diatomite filtration is a kind of coating filter with diatomite coating as filter layer. It mainly uses mechanical screening to treat water containing micro suspended solids. The core part of the filter is composed of filter screen, support net and outer frame. Each filter element is a tube with a hole as the skeleton, and the outer surface is wrapped with wires and coated with diatomite coating. The filter element is fixed on the clapboard, and the upper and lower parts of the diaphragm are raw water chamber and clean water chamber. The whole filtration cycle is divided into three steps: membrane laying, filtration and backwashing. The thickness of the filter membrane is generally 2-3mm, and the particle size of diatomite is 1-10 μ M. After filtration, water or compressed air or both are often used for backwashing. The advantages of the filtration are good treatment effect, small flushing water (less than 1% of the production water), and small floor area (less than 10% of the common sand filter area)
