[High school chemistry] filtration is one of the operation methods for separating solution and solid insoluble matter. The sediment needs to be washed if necessary. Add a small amount of distilled water to the filter No idea what the availability is, it should be soluble impurities. 'Availability' should be soluble, and 'soluble impurities' are other substances that can be dissolved in water and attached to precipitation. For example, filter calcium carbonate precipitation and calcium hydroxide solution, and wash out calcium hydroxide attached to the surface of calcium carbonate after filtration. at this time, calcium hydroxide is a 'soluble impurity '. If you don't understand, it should be a typo. it is an impurity soluble in water. after washing, it can be dissolved in water and separated from sediment. It's obviously a typo, soluble impurity! The title is wrong. it is soluble impurities.

Fully automatic self-cleaning filter for fully automatic filter The fully automatic self-cleaning filter is a precision equipment that directly intercepts impurities in the water by using the filter screen to purify the water quality and protect other equipment of the system. The water enters the self-cleaning filter body from the inlet, due to the intelligent (PLC, PAC) design, the system can automatically identify the impurity deposition degree and automatically discharge the sewage valve signal. The automatic self-cleaning filter overcomes many shortcomings such as small amount of pollution, easy to be blocked by dirt, disassembly and cleaning of the filter part and inability to monitor the filter status, it has the function of filtering raw water and automatically cleaning the filter element for automatic sewage discharge, and the system provides uninterrupted water supply when cleaning the sewage discharge, which can monitor the working state of the filter and has a high degree of automation.
