How much is a fresh water purifier? The water purifier is also called water purifier and water filter. The core technology of the water purifier is the filter membrane in the filter element device. The main technology of the water purifier comes from the UF membrane and RO reverse osmosis membrane, it is a small water treatment equipment for deep purification of water quality according to the requirements of water use. Generally speaking, the water purifier refers to a small filter used as a household.The water purifier can be divided into many kinds according to different purification principles and processes. Among them, RO reverse osmosis technology has the highest filtration accuracy (filtration accuracy is 0.0001 microns), since the pore diameter of the reverse osmosis membrane is only one in 100,000 of the diameter of the hair wire, only water molecules and dissolved oxygen are allowed to pass through, all the impurities contained in the water, such as pesticides, bacteria, viruses, heavy metals and o
What is the role of the filter used to raise goldfish? The water in the fish tank will be contaminated by fish feces, food residues, aquatic leaves.In people's imagination, the suspended matter visible in the water is filtered out,The purpose of keeping the water clear and transparent has been achieved,In fact, this is only the primary function of filtering,We usually call it mechanical filtration.The modern ornamental fish tank filtration should have mechanical filtration at the same time,It also has the function of biological filtration,Physical filtering is also needed sometimes.One of the most important is biological filtration.The so-called biological filtration,It is through bacteria attached to the filter material,Decompose or convert harmful substances dissolved in water into harmless substances.Physical filtration is to use the unique adsorption function of some materials to make water purification.Physical filtering is used for a short time under special circumstances,For example, in order to remov
