2, activated carbon is adopted to be the purifier of filtration medium: the heterochromatic and peculiar smell in water can be eliminated, but other objectionable impuritiess such as the bacterium in water can not be removed, also very poor to the removal effect of silt, iron rust.
3, adopt reverse osmosis to be the pure water device of filtration medium: to remove useful and objectionable impurities in water completely, output be pure water.And needing pressurization to power up, the utilization ratio of water is low (waste water is many, pure water is few, generally will waste the tap water of about 50%).Purification cost is high, and flow is little, only solves Drinking Water Problem.
4, soft water filtration unit: generally adopt regeneration sodium form resin to be filtration medium, the calcium in replaceable water, magnesium ion, only plays softening, reduction water hardness effect, can not purify, remove the various noxious pollutants in water.
5, tubbiness purifier: be contained in the tubbiness purifier on water dispenser, generally adopt the filtration mediums such as activated carbon, pottery, mineralization ball, filtering accuracy is not high, be the filter type retained completely, cleaning inconvenience, easily forms secondary pollution, water production rate is little, and just location solution is drunk water problem.
6, ultra-filtration membrane is adopted to be the purifier of filtration medium: the aperture of ultra-filtration membrane is 50-500nm, can effectively remove the objectionable impuritiess such as silt in water, iron rust, suspended substance, colloid, bacterium, larger molecular organics, and retain the mineral trace element useful to human body.But small molecular organic compounds and heavy metal can not be leached, have certain defect.
7, mixed-media filter: according to the functional characteristics of different filtration medium, adopts the combination of multiple technologies, to reach wider water conditioning scope, effectively removes the various objectionable impuritiess in water comprehensively.But desirable water purification quality can be reached, determine its membrane module, if ultra-filtration membrane, have certain defect.If reverse osmosis membrane, then " pure have a surplus, under-nutrition " can not long-term drinking, needs electricity consumption simultaneously, wastes energy, uneconomical.
