Q:Working principle and structure performance of horizontal vacuum filter
The slurry is arranged horizontally on the filter medium, and the solid and liquid separation is realized by utilizing the gravity of the slurry and the suction of the vacuum negative pressure. The continuous horizontal vacuum belt filter can be applied to the materials under various concentration conditions. The utility model can automatically and continuously complete the technical operations of filtering, filtering cake washing, slag unloading, filter cloth regeneration, etc., and the mother liquor can be collected in a sectional way with the washing liquid of the filter cake.
Q:How do you make your own cigarette filter? The kind of water. You have the best picture

Q:The filter directly connected to the water pipe, the filtered water can also be drunk
Such as organic pollutants, inorganic salts, any additives and all kinds of impurities, is to meet the drinking water hygiene standards for water as raw water. Through electrodialysis, ion exchange and reverse osmosis
Q:Water purifier bottom leakage is what is the reason?
Two is the upper rubber ring deformation, there is a gap. Causing slow seepage
Q:Press the water purifier in the kitchen to get the water boiled. Why is it white?

When will the domestic brands turn over and be the masters?"At present speaking, foreign brand competitiveness will be stronger, after two or three years, domestic brands will come up.". Because foreign brands rely on its technical forces, as well as its brand advantages. Three years later, domestic brands still have advantages." Zhang told reporters.
Q:Why can't the filter of fish tank effectively filter water quality?
No culture of nitrifying bacteria filters can only help you filter large amounts of debrisNitrifying bacteria are substances that help break down waterNitrifying cultures require ceramic rings, or glass rings (placed in a filter, and cotton filters below)The incubation period was 7-21 daysWhen you feed, after a period of time, the water is clear, it shows that the success of culture, the shorter the time, the more bacteriaNitrifying bacteria will die in the absence of oxygen. When the filter cotton or biochemical cotton is replaced, the nitrifying bacteria living in it will disappearNitrifying bacteria generally live in ceramic rings and or glass rings
Q:What's the difference between a backwash filter and a self-cleaning filter? What about the two?
These are two different conceptsBackwashing means washing the filter against a near saturated filter in the opposite direction of the normal flow
Q:Can the drinking water filters sold in the market achieve the purpose of filtration?
4, reverse osmosis: filter pore size of 0.0001-0.001 microns, typical applications such as reverse osmosis membrane, can filter out ions, basically only water molecules through, but need energy consumption, waste water more;The drinking fountains sold on the market are generally ultra - filtration machines, reverse osmosis machines, ceramic machines, each with its own characteristics, can be purchased according to their own needs:1, the whole house water purification: it is recommended to buy ultra filter machine, low cost, no energy consumption, long service life, purification capacity, after the activated carbon, you can drink straight;2, straight drink: it is recommended to use reverse osmosis machine, but the need for electricity pressure, waste water accounted for 7.
