Q:Why do filters become muddy when filters are used in fish tanks?
To build an ecological filtration system in the tank, the ecological filter effectively, the decomposition of organic matter, not only water, solid waste water filtering and removing, become very clear, stable water quality, but also can effectively reduce the occurrence of fish diseases.
Q:The filter directly connected to the water pipe, the filtered water can also be drunk
Distillation and other suitable processing methods, sealed in the container, and does not contain any additives, colorless and transparent, can be directly consumed. Space water sold in the market and distilled water are pure water.
Q:What is a vacuum filter?
General principles of filter selection:1 、 import and export pass:In principle, the inlet and outlet path of the filter shall not be smaller than the inlet diameter of the matched pump, which is in conformity with the caliber of the inlet pipe2. Nominal pressure:Determine the pressure level of the filter in accordance with the maximum pressure that may occur in the filter line3, the choice of mesh hole:The main consideration is to intercept the impurity particle size, according to the medium flow process requirements. Various sizes of wire mesh can intercept size, check the list "filter specifications"4 filter material:The material of the filter is generally chosen to be the same as that of the connecting process pipe. For different service conditions, the filter of cast iron, carbon steel, low alloy steel or stainless steel can be considered5, filter resistance loss calculationWater filter, under normal rated flow rate, the pressure loss is 0.52 ~ 1.2kpa
Q:What are the hazards of drinking water filters?
Are you talking about the prefilter in the water manager?With the kind of Ppmian, 6-8 months to replace the core, waste your time and money, but it is inside the rust and sediment barrier,
Q:Reasons for increasing water quality of water purifier in household filter
The process is as follows: no filtered water - the first stage filtration of a water purifier through a household filter to remove large particulate contaminants - - second levels of filtration to remove particulate contaminants
Q:Is the mineral water purified from the purifier pure mineral water?
Mineral water is mineral. Pure water is distilled water, that is pure water
Q:Why is the water filter in the bucket more and more slow?
Well, that's normal. Let's get to know his features and materials first.1, in general, the filtering water purifier has the advantages of simple structure, with Ppmian, activated carbon filter, its ability is limited, can only be used for coarse filtration using ordinary water purifier, 3+2 water purifier filter water heating to boil drinking the best. Known as ordinary water purifier (the industry name: 3+1 water purifier, 3+2 water purifier).
Q:How do you make the filter in the simplest way?
Put the materials in order and pour the water slowlyThe filtered water is caught in a container and sterilized as drinking water
Q:Is the filtered water of pure water filter not nutritious?
The minerals are still there, but the RO reverse osmosis filter comes out with pure water, which contains nothing.
Q:Does air purifier use tap water or mineral water?
The air purifier doesn't need water. What kind of air purifier did you buy?! Will it be just a humidifier?
