What is the difference between a filter water dispenser and a filter faucet? Which one is better? The filter faucet is actually a very small filter. To be honest, this thing is really useless, but it's just good-looking. don't look at the advertisements of those merchants.However, household water purifiers are really useful when they arrive, and water purifiers are divided into two categories.One is the ultra-filtration (UF) machine and the other is the reverse osmosis (RO) machine. The filtration accuracy of the UF membrane is 0.01-0.1 microns, which can only remove sediment, rust, most bacterial viruses and salt in water. The filtration accuracy of the reverse osmosis membrane is 0.1nm level. in addition to filtering the above substances, the salt in the water, various yin and yang ions can be removed. Obviously, the water quality of the RO machine is better than that of the UF machine. for a simple example, UF produces water equivalent to Nongfu mountain spring, and RO produces water equivalent to Yibao.
Introduction to homemade fish tank filters There is a good filtration device in the fish tank,Only by keeping good fish and changing less water.First, the filtering methods mainly include physical filtration, biological filtration, chemical filtration, etc.Two, there are many types of filters in the form of filters,For example, air lift biochemical cotton filter, bucket external filter, top filter of aquarium, fish tank filter with shape, etc.1. air lift biochemical cotton filter sucks biochemical cotton into the upper air pump or water pump without bottom connection,The flow of gas in the water drives the flow of water to circulate in biochemical cotton.The residual bait, biological excrement and other organic substances in the water can be absorbed on the surface of the sponge.Advantages of gas lift biochemical cotton filter: simple structure, low unit price,Use it directly in the fish tank water.Disadvantages: the filtering principle is simple and the effect is poor,Clean bi
