How about the front filter of the elevation lq1-10a? 1. the front filter is of course useful. Because the worse the water quality, the greater the role of the front filter. Because the role of the front filter is the preliminary filtration of the whole house water, mainly the filtration of sediment, rust, and large particles in the pipe network. At present, the phenomenon of secondary pollution of tap water pipes is relatively serious. tap water will have a lot of impurities in our home through the water pipes. filtering out these impurities can avoid damage to the human body and skin, it can also protect the water purifier, water heater, shower, faucet and other facilities in the home.2. the front filter is the first coarse filtration equipment for the whole house water, which can filter the sediment, rust and large particles in the tap water. The front filter is generally installed at the front end of the pipeline, so it is named after the word 'front'; and 'filtering' refers to the basic principle of suc
What is the main role of security filters? Manufacturing multi-media filter in liaojingPrinciple and process flow of fluorine removal filterFluorine-containing water passes through the active alumina adsorption filtration layer with large specific surface area. Fluorine removal filter at pH 5 ~ Under the condition of 6, the fluorine ion in the water is removed by adsorption to form a hard-to-dissolve fluoride. the reaction is as follows: r2so 4 + 2F-= R2F2 + SO 2-, after the adsorption fails, regeneration with aluminum sulfate solution to restore its adsorption capacity. The ratio of its dosage to fluorine removal is 60: 1, the regeneration concentration is 1%-2%, and the operation is 3 ~ After 4 months of cleaning with a concentration of 3.5% HCL solution, it can be washed with fluorine removal water after cleaning. The time is 8 ~ 10 min. when the pH value of raw water is greater than 7, it is generally adjusted with carbon dioxide gas.It is mainly used after multi-media pretreatment and filtration, befo
