Large scale reverse osmosis irrigation pure water equipment

Large scale reverse osmosis irrigation pure water equipmentThe customer uses groundwater as the raw water for pouring concrete on construction sites, and the iron and manganese levels are severely exceeded. Our process for this is to first pump the water into a water tank, aerate it, and then enter the iron and manganese removal device for treatment.After flushing or adding oxidants to groundwater containing iron (manganese), iron (manganese) ions in the water begin to oxidize. When the water flows through the manganese sand filter layer, contact oxidation reactions occur in the filter layer, as well as biochemical and physical interception adsorption on the surface of the filter material, causing iron (manganese) ions in the water to precipitate and be removed. Especially in the process of treating micro polluted manganese containing groundwater, iron bacteria can not only effectively remove iron and manganese, but also use ammonia in the water as a nutrient source for metabolism. With the participation of other bacteria, they can also achieve the effect of removing ammonia nitrogen. The iron and manganese removal filter material is mainly made from natural minerals through a series of complex processes and modifications. The particle size is 0.5-2.0mm, the bulk density is 0.9, and the color is gray green. The iron manganese filter material is extremely sensitive to iron and manganese in water. As long as iron and manganese ions exist, they will be firmly adsorbed in the pores of the filter material.

Large scale reverse osmosis irrigation pure water equipmentAfter being treated by the pre treated iron and manganese removal device, the water is filtered through a precision filter and then pumped into the reverse osmosis host membrane through a high-pressure pump to meet the production water demandIt is a membrane separation method that utilizes the function of selectively permeable (semi permeable) membranes with pressure as the driving forceWhen the pressure applied in the system is greater than the osmotic pressure of the inlet solution, water molecules continuously penetrate the membrane, flow into the central pipe through the water production channel, and then impurities such as ions, organic matter, bacteria, viruses, etc. in the water flow out at one end, which are trapped on the inlet side of the membrane and then flow out at the outlet end of the concentrated water, thus achieving the purpose of separation and purification.Reverse osmosis methodIt can adapt to various types of raw water with high salt content, especially in water treatment projects with high salt content, and can achieve good technical and economic benefits. Desalination rate of reverse osmosis methodImprove, recycling rateHigh, stable operation, small footprint, easy operation, reverse osmosis equipment not only removes salt, but also removes most bacteria, colloids, and high molecular weight organic matter.
