Implementation process:
1, tap water is through front two-stage preprocessing filter element, large granular impurity and the chlorine residue etc. such as filtering silt particle, iron rust, algae.
2, water enters film bodyguard (KDF filtrate carries out except divalent salts, demineralized water, and anti-bacteria, except chlorine residue) through front two-stage pre-treatment.
3, the water of third stage preprocessing filter element to prime purifies further, ensures the influent quality of RO film.
4, the pretreated water of the third stage can provide as domestic water, meet wash dish, wash one's face and rinse one's mouth, sanitation and hygiene etc.
5, topping-up pump carries out supercharging to water, allows hydraulic pressure reach the operating pressure of RO film.
6, temperature steady flow process: three grades, water source preprocessing filter element; enter heating component 84; temp probe 87 before film responds to inflow temperature; when film inflow temperature is less than 10 DEG C, control heating component 84 by intelligent controller and start, by constant for water temperature before film at 25-30 DEG C; when water temperature over-high before film; control overheating protection pressure switch 83 by temperature probe 87, intelligent controller 16, micro pump 82 starts, and prevents water temperature over-high before film.Flow inductor 88 plays does current stabilization effect.
Reverse osmosis membrane is in former water water temperature lower than less than 10 DEG C, and water production rate obviously declines, thus causes water purification mechanism water overlong time, and even do not shut down, topping-up pump load increases, and affects film work-ing life.Therefore, thermostat generally can not run under normal conditions.
7, water enters RO film, utilizes reverse osmosis membrane separation technology to purify.
8, through the waste water of reverse osmosis membrane group 7, under the effect of topping-up pump 6, again return of waste water device 47 is passed through with the flow of 300ml/min.Mix with former water after the softening desalination of polishing resin through KDF filtrate, weaker concn, enter reverse osmosis membrane group 7 at a high speed, again filter purification.Because the glassware for drinking water entering reverse osmosis membrane group 7 has the feature of lower concentration and high flow rate, thus reduce the generation of concentration polarization in film, extend the work-ing life of film.
9, after reverse osmosis membrane group 7, wastewater outlet side is provided with smart water quality monitor 412, can respond to the concentration of waste water salt, feed back to smart valve 10.When concentration value reaches certain set(ting)value, smart valve 10 opens water route, carries out instantaneous discharge, thus reaches flushing reverse osmosis membrane group 7 surface, reduces the effect of salt concn.
10, because of the sofening treatment of the front water source of film through film bodyguard, most incrustation scale is removed, useless only than being reduced to trace waste water discharge by 2:1.Thus improve the rate of recovery of water, reduce discharge of wastewater.
