Reverse Osmosis System Water Purification Machine RO-700L/H

Product ExplanationReverse osmosis water purification machine to treat fresh water for drinking/mineral water. Our plant could make drinking water, mineral water, pure water and potable water from the water sources: Ground, spring, well, river, borehole, brackish, lake water and etc.Capactiy: 300LPH to 100, 000LPHPlease advise your water analysis report, Product water quality standard and output capacity, we will provide proposal to you soonest.Looking for serious buyer and long term business relationship.1. The RO water treatment plant process/step:Raw water - Raw water tank - Raw water booster pump - Mechanical filter (Quartz sand filter) - Activated carbon filter - Precise filter/PP sediment filter - High-pressure pump - Reverse Osmosis Assembly - Pure water tank2. The main struction of the machine:1). Quartz sand filter.2) Activated carbon filter3). High pressure pump4). RO Membrane assembly5). DisinfectionPlease find more information of each parts:Quartz sand filterThe raw water is purified simple by the filter. The filter mainly removes the suspend materials, 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 back flushed. Usually, the filter should be back flushed once before operation every day and also be back flushed with gas once a week.Activated carbon filterThe active carbon is made of wood, coal, fruit shell (coconut) 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 infecting of the water. The filter mainly removes the organic substance, chlorine, odor, chromo 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 back flushed every week.High pressure pumpThe pump supplies the pressure needed to push water through the membrane, even as the membrane rejects the passage of salt through it. Typical pressures for range from 225 to 375 psi (1.6 to 2.6 MPa). In the case of seawater, they range from 800 to 1, 180 psi (6 to 8 MPa).Membrane assemblyThe 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 technology 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 osmosis through the membrane contains a lot of solute and suspended substance, and it will be drained out as waste water.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 & TDS meter.
