Is the water purifier more waste?
3, PP cotton: basic does not produce waste water, only interception of large particle impurities, as with coarse filter;4, activated carbon: only adsorption, generally do not use as a single filter materials, can be used as the last level of direct drinking water, improve the taste
2, ultrafiltration membrane: membrane pore size of 0.02 microns, basically no waste water, only to retain organic macromolecules, viruses, bacteria and impurities
Depends on what type of purifier you're using1, reverse osmosis: membrane pore size is nanoscale, allowing only water molecules through, the basic 70% is wastewater
