50000LPH  industrial water treatment machine

This is the RO system for producing drinking. The producing capacity is10000L/H. The water supply is tap water. The water is first being removed the suspended matter, micelle and other impurity by the quartz sand filter. Then it is being got rid of the organic substance, chlorine, chroma, odor and etc by the active carbon filter and softener filter. The above device compose the consummate pretreatment system. The water which is being pretreated reaches the requirement of the RO system. So as to make the RO equipment run stably during a long period.

The abio-salt, organic substance, bacteria, heat source and other impurity in the water have been removed after the water was being treated through RO system. The ratio of salt-doffed is in the range of 97%-99%.

There are two modes of operation in the system: auto and manual. The system runs automatically by adopting Water Sensor, and Pressure Sensor. The system can produce water automatically in the mode of auto. It is friendly used and safe.

2. Technical process of the reverse osmosis system

Raw water→Raw water tank→Raw water pump→Machine filter→Active carbon filter→Softener→Security filter→ high –pressure pump→ RO→Pure water tank→Water

↑UF→Pure water tank→Water

3. The reverse osmosis water purifier work principle.

3.1 Disinfectant-adding device

Coagulation devices, add coagulating agent (aluminum sulfate) before the raw water enters into active carbon filter. This is uses to form the suspensions, colloids, microparticles etc into flocks large particles in order to got rid of them more easily by sand filter. The PH adjustment device can adjust the PH valve of raw water, making the inlet-water of RO optimization.

3.2 Machine filter( The quartz sand filter.)

The raw water is purified simple by the filter.  The filter mainly removes the suspend matter, colloid and other big impurity. If pressure dispersion of the water entering and water out exceeds 10Psi(0.7kg/cm²)or the water out SDI>5, the filter need to be backflushed.  Commonly, the filter should be backflushed once before operation every day.

3.3 The active carbon filter.

The active carbon is made of wood, coal, fruit shell (stone) and other carbonaceous material through the method of chemical activation or physical activation.  It has a great deal of micro-holes and huge surface, so it has very strong physical adsorption capability to adsorb the organic infectant of the water.  The filter mainly remove the organic substance, chlorine, odor, chroma and etc to make the left chlorine ≤0.1mg/l.  So as protect the RO membrane from damage by the chlorine. The active carbon should be replaced every 12 to 15 months according to the content of the chlorine mostly. Commonly, the filter should be backflushed every week.

3.4The RO device.

The RO device removes the hydronium, organic substance, colloid, bacteria and other impurity by the method of membrane.  And the water can be desalted and purified. The theory is as follows. The treated water and the untreated water are separated by the membrane; the treated water osmoses to the untreated water. There is osmotic pressure between the two. If the pressure is added to the untreated water and the pressure of the untreated water is bigger than the osmotic pressure, the water of the untreated water osmoses to the opposite position of the water. This applies the reverse osmosis to the desalted water. That is to say the untreated water is purified into the pure water through the RO membrane under adequate pressure. The left water which can not osmose through the membrane contains a lot of solute and suspended substance, and it will be drained out as waste water.

The RO device consists of 5µm precision filter, the first high-pressure pump, the second high-pressure pump, the middle tank, the pressure vessel, the RO membrane module, the pressure gauge, the flowmeter, the conductivity meter and etc.

The water must be pretreated before entering into the RO system, or it will bring damage to the RO membrane.

The RO system not only can be used for desalination, but also for filtering the organic substance and bacteria.

The production of water is monitored by the liquid crystal display conductivity meter.

The RO system needs be cleaned termly, including the stainless steel pump, filter, disinfectant tank, valve and other components.

Commonly, the RO system should work once every day.  If it does not work in one week, it must be protected by some measures, or the service life of the membrane will be serious affected.
