◆Single-stage reverse osmosis equipment
Single-stage reverse osmosis equipment is also known as one-stage reverse osmosis, the raw water through the pretreatment system, precision filters, and then through the high-pressure pumps, and then send the raw water to the reverse osmosis device, the direct output of the water is known as a single-stage reverse osmosis.
Single-stage reverse osmosis equipment features: single-stage reverse osmosis under the action of external pressure, so that certain components of the solution selectively through, so as to achieve the purpose of desalination, purification or concentration separation of a practical technology; it can remove the vast majority of the ions in the water, but also remove the water of the microscopic particles, bacteria and impurities such as organics, is the current water treatment equipment in the advanced, economic means, single-stage reverse osmosis Single-stage reverse osmosis is mainly used in water quality is relatively good, or water quality requirements are not very high users.
◆Double-stage reverse osmosis equipment
Double-stage reverse osmosis equipment, also known as two-stage reverse osmosis, two-stage reverse osmosis preparation system, is the tap water as raw water, first through the pretreatment, security filtration, and then into the precision filter filtration, the first level of high-pressure pumps pressurized to the first level of reverse osmosis system, the first level of reverse osmosis output of the water and then the second level of high-pressure pump pressure to the second level of reverse osmosis system, the produced water is known as double reverse osmosis system, and the produced water is called double reverse osmosis system. The water produced is called two-stage reverse osmosis.
Double-stage reverse osmosis equipment features: particles in the water can be removed, colloids, organic impurities, heavy metal ions, bacteria, viruses, heat and other harmful substances and ninety percent of the dissolved salts, the system desalination rate is as high as ninety percent or more, two-stage reverse osmosis is mainly used in the poorer quality of water or water quality requirements for the use of higher users.
