According to above data, the reverse osmosis membrane usage period is 3 years, and then the wastewater discharge of every water purification machine is 2.58 tons/month, and on average need expend tap water every year is 30 tons, 90 tons/3 years.
Below two types of situation " tap water " quantity discharged can't estimate:
1. if water purification machine used in winter, particularly northern user is because the relation at the end falls in water temperature; With the new clothes water purification machine is example, and the reverse osmosis membrane pure water amount of producing will drop to 5～10%, even lower; So, a large amount of tap water is not parked in from the waste water mouth and enters water drain.
2. machinery breakdown produces; As: when HPP no-voltage fault, high-voltage switch gear fault, water purification machine principal fault; Machine loses automatic protection functions, a large amount of tap water that continuous non-normal working brings takes place not shut down enter water drain unawares, must close water intaking valve immediately after user's discovery and just stop; These all situation comprehensive, it is immeasurable making user's's " tap water " waste.
Therefore, existing reverse osmosis water purification machine is a kind of immature, as to have major defect product that designs, and if things go on like this will receive the restriction of government administration section and eliminating of market.
Example: drink and eat (direct-drinking water, cook water such as food) every day by a people and, on average need emit " the dense water " of about 12～18L every day, then can drain in every month 0.36～0.5 ton, will slattern 4.3～5 tons of tap water the whole year with 3 liters of calculating.If there is 30% people to use in the city of one 1,000 ten thousand population, then will waste about 1300 ten thousand steres of tap water every year, be equivalent to the storage capacity water storage of a medium-sized reservoir, startling such wastage be! And one of country that China's Freshwater resources that to be United Nations generally acknowledge lack is all over the world, deficient more like countries and regions fresh water data such as the Middle East.
These " dense water " owing to can not get reasonably using becoming " waste water ", and the suggestion of reverse osmosis water purification machine manufacturer to get up these wastewater collections as washing, flush the toilet, water flowers etc. be unpractical.Simultaneously; Manufacturer painstakingly conceals the wastewater discharge of reverse osmosis water purification machine in sales process; Make the human consumer lose right to know; Most human consumer is that tap water pours off from water drain in vain under the situation of consciousness not, causes the significant wastage of tap water, and this obviously is that the energy-saving and emission-reduction of being advocated with country, water-saving theory are disagreed.
What China utility model patent ZL201020544206.8, ZL201020280703.1, ZL201020544210.4 adopted is that dense water returns Technology; What China utility model patent ZL201020544206.8, ZL201020280703.1 adopted is that the dense water of double pump formula returns technological principle, and promptly a HPP, a dense water return pump; China utility model patent ZL201020544210.4 adopts the monomer bull pump to realize that dense water returns technological principle.
