5 stages reverse osmosis water filter system without tank 400G Water Treatment Machinery

0peration Principle:The RO system adopts U.S. high-tech reverse osmosis technology. 

This automatic reverse osmosis svstem is composed of five filtration stages. 

First, the raw wateris filtered by three pre positive cartridges.

The first stage: PPF cartridge, remove suspended substance and other substances up to 5 micron in raw water;

The second stage: granular activated carbon cartridge.

The third stage: high density activated carbon cartridge, to remove odor, chlorine and its outgrowthin raw water.After above three stages of filtration, the filtered water is pushed into he fourth stage.

The fourth stage : the reverse osmosis (RO) membrane by a high-pressure pump. Since the aperture ofthe RO membrane is only 0.0001micron, bacteria and filterable virus can pass the RO membrane only if the bacteria would be reducedin size 4000 times. and filterable virus would be reduced in size more than 200 times. Consequently, any super fine impurities, harmful soluble solid, bacteria and virus in water is blocked by the high density RO membrane.  The RO membrane can also filter other impurities and contamination from the filtered water. The harmful substance is automatically removed by means of a waste water outlet. The water filtered through the RO membrane enters a pressure tank for storage. When the user turns on the goose-neck faucet, the purified water will go through the fifth stage.

The fifth stage : post positive bacteriostatic activated carbon filtration (mineral ball or UV light can be added behind fifth stage to meet the requirement of the customers) before it goes to the faucet. The system controls the water purification process automatically. When the pressure of raw water is too low or the water storage tank is full, the system will stop the purification machine automatically: When the water pressure returns to the normal level, the purification machine will turn on automatically. 

The water purified by the RO system is pure drinking water without bacteria and impurities, rich in oxygen, tasty and excellent for your health.
