Which is the best filter for pure water machine:
There are many types of filter elements. The effect is not the same. The filter element is divided into foreign and domestic points from the place of origin. Generally speaking, the technology of foreign brands is relatively mature, the history is relatively long, and the quality and technology are relatively reliable. Domestically, large companies and joint venture brands are relatively reliable in quality and technology. Filters are most important to look at the structure and hierarchy. Generally speaking, only the price of PP cotton, carbon core and ceramic core is relatively low, and the filtering effect is also general. Only large impurities and different colors are filtered out. Some not only have the first two kinds of filter layers, but also their own technology, such as KDF alloy filter material, multi-pleated filter technology, etc. This filter filter effect is good, basically it is a relatively high-end product on the market. The level of the filter is now a selling point for many water purifiers. Some level 3 filters, some level 5 filters, and even level 7 filters. No matter if you are level 5 or level 7, in addition to KDF alloy filter material, multi-pleated filter technology, ultrafiltration membrane, etc., just add a few layers of core, PP cotton, pre-filter.
Water purifier filter standard configuration is 1, 5 micron 10 inch PPF, 2, 10 inch UDF (granular activated carbon) 3, 10 inch CTO (precision activated carbon) 4, RO (reverse osmosis) membrane 5, rear coconut shell activated carbon, market The retail price is 20 yuan / support; 30 yuan / support; 30 yuan / support; 300 yuan / support, 50 yuan / support. PPF has no technical content, quality is similar, the quality of activated carbon is Xifeng of Gansu and Hako of Xiamen The quality of coconut shell carbon in Germany and Malaysia is good.
The drainage pump is often used for urban waterlogging, rural and forest fires to prevent and deal with emergencies. It supplies water to the fire site through pressure pipelines or fire monitors, and can also be used for drainage when large-scale flooding occurs.
When there is a considerable distance between the ponding point and the drainage site, the supplementary pipe can be used to extend to 1000m to realize long-distance drainage. When there is water, it can replace the fire truck and be used as the pump station. Equipped with hydraulic bit, it can extinguish peat fire and also can use fire monitor.
