Boiler water filter boiler water is there any need to add a filter, if there is First of all, it depends on what kind of boiler you are,Low pressure boiler,Medium pressure boiler,High-pressure boiler or critical boiler,And is it tap water or softened water that supplies water to the boiler?A slightly more stringent boiler,Generally, it is softened water after treatment,The process is filter first-class reverse osmosis of quartz sand filter activated carbon filter softening device.Can prevent scaling of boiler.Shenzhen pure water No. 1 Water treatment for your answer.
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
In raw water or wastewater treatment, AFF asymmetric fiber filter is used as an efficient and fast filtration equipment. What are the features of backwashing and what are the principles? The DECEAD asymmetric Fiber Fast filter adopts the asymmetric fiber bundle material as the filter material,Both the advantages of particle filter material and fiber filter material.When backwashing,Due to the poor proportion of core and fiber,The tail fibers spread and swing with the backwashing flow,Have a strong traction,The collision between the filter materials also aggravated the mechanical force of the fiber in the water,Make it easy for solid particles attached to the surface of the fiber to fall off,Thus improving the washing degree of the filter material,At the same time, the filter material has the backwashing function of the particle filter material.
