What is the RO filter system? Chinese name: reverse osmosis, English name: reverse se osmosisRO;Reverse osmosis;RO Definition 1: a kind of pressure that is driven by pressure above the pressure,The selective membrane can only pass through water but not through the selective permeability of the solute,Membrane separation process for extracting fresh water from water bodies.Subject: Electric Power (first-level subject );Thermal automation, power plant chemistry and metals (secondary disciplines) Definition 2: Make the solvent (water) in the solution, driven by pressure, enter the low-pressure side of the membrane in the opposite direction of natural penetration through the semi-permeable membrane,So as to achieve the process of effective separation.The basic working principle of reverse osmosis is: using a special high-pressure water pump,Add raw water to 6-20 kilograms of pressure,Let the raw water penetrate through the pore diameter under the action of pressure is only 0.Reverse osmosis membrane of 0001
Reverse osmosis water treatment device effluent pH value is higher than 5? (1) the hydrolysis of cellulose acetate membrane is easy to cause deterioration of the performance of the reverse osmosis device. For this reason, the pH value of the water must be strictly controlled, and the pH value of the water supply must be maintained at 5-6, and the composite film can be PH3-Run under the PH11 range.(2) when the amount of secondary sodium injection is insufficient and the free chlorine in the water supply cannot be measured, there will be sticky mud on the membrane assembly of the reverse osmosis device, and the pressure difference of the reverse osmosis device will increase.However, for composite films and polyamide films, the amount of free chlorine entering the membrane assembly must be strictly controlled, and exceeding the specified value will lead to oxidation and decomposition of the membrane.(3) if the water with the F1 value exceeding the standard is supplied to the reverse osmosis device as t
