Industrial reverse osmosis pure water treatment equipment component functions and water inlet parameters
Industrial Reverse Osmosis pure water treatment equipment and water utility component parameters of the article: reverse osmosis process in ultra-pure water equipment is a very important part in the operation to control many elements of pre-treatment the pH of the feed solution , Suspended solids and microbial mass, etc., will affect the effect of reverse osmosis. Therefore, if necessary, effective pretreatment measures such as pH adjustment, filtration, disinfection, etc. must be taken on the raw water to give full play to the effectiveness of reverse osmosis. Work efficiency. The following environmental protection introduces the water inlet parameters of an industrial reverse osmosis purified water treatment equipment: 1. Industrial reverse osmosis pure water treatment equipment has requirements for water temperature, and reverse osmosis membrane elements have certain requirements for water quality. High temperature membrane elements are produced outside The composite membrane requires the inlet water temperature to be controlled at 0~45°C, and the cellulose acetate membrane requires the inlet water temperature to be controlled at 0-40°C. 2. For the requirements of inlet water pressure, the highest inlet pressure of industrial membrane used in brackish water treatment is 600 psi (4.16Mpa), and the highest inlet pressure of seawater desalination membrane is 1200 psi (8.27Mpa). 3. The maximum water flow rate of the membrane, the maximum water flow rate of 8 membrane elements is 75gpm (17t/h). The maximum water flow rate of 4 membrane elements is 16 gpm (3.6t/h). 4. The damage pressure of a single membrane element, if the pressure of a single membrane element of Rongguo is too high, it will cause damage to the membrane element. Therefore, the maximum pressure of a single membrane cannot exceed 68.9 Mpa (10 psi). 5. The ratio of concentrated water to permeated water. The anti-fouling power of each membrane is limited. Therefore, the ratio of concentrated water to permeated water of the membrane is required. Therefore, a single membrane element is required to concentrate water and permeate. The minimum ratio of water passing is 5:1. The functions of industrial reverse osmosis pure water treatment equipment components: (1) Raw water tank, function: storage system raw water, which regulates the influent water, and also plays a certain role in precipitating impurities in the influent water. (2) Sand filter, function: preliminary removal of sediment, impurities, suspended solids and other particles in the water to reduce the turbidity of the water. (3) Carbon filter, function: use the principle of carbon adsorption to absorb different colors, odors, residual chlorine, etc. (4) Water softener, function: Use special resin for soft water to absorb and replace calcium and magnesium ions in the water to reduce the hardness of the water. (5) Security filter, function: prevent large particles of impurities from entering the reverse osmosis membrane, causing damage to the membrane, and protecting the reverse osmosis membrane. (6) Reverse osmosis host, function: mainly through reverse osmosis filtration to achieve the purpose of producing pure water. (7) Two-stage pure water tank, function: store reverse osmosis product water and provide water source for the back system. The above is an introduction to industrial reverse osmosis pure water treatment equipment. Environmental protection has always produced safe and standard water treatment equipment in accordance with national requirements, not only purified water equipment, but also the well-known purified water equipment, softened water equipment and many other equipment useful for environmental engineering.
