I. Basic Principles of Reverse Osmosis Treatment Equipment for the Pharmaceutical Industry

　　ROReverse osmosis technology is a high-tech water treatment technology. It works by relying on the characteristic of reverse osmosis membranes to separate solvents and solutes in solutions under pressure. "Osmosis" is a physical phenomenon. Reverse osmosis occurs in water containing salt and various fine impurities(That is, raw water)Applying a greater pressure than natural osmosis causes water to reverse permeate from the side with a higher concentration to the side with a lower concentration, while the vast majority of fine impurities, organic matter, heavy metals, viruses and other harmful substances in the raw water are discharged through the sewage outlet.

　　Ii. Main Process Flow Description of Reverse Osmosis Treatment Equipment for the Pharmaceutical Industry

　　1Raw water tank(Optional)

　　It stores raw water and is used to settle large sand particles and other sedimentable substances in the water. At the same time, it buffers the impact of unstable water pressure in the raw water pipe on the water treatment system.(The response of pressure sensing caused by too low or too high water pressure).

　　2Raw water pump

　　Constant system water supply pressure and stable water supply volume.

　　3Multi-media filter

　　The filter with multiple filtration layers is mainly designed to remove particles such as sand, rust, colloidal substances and suspended matter contained in the raw water20umThe above-mentioned substances can be controlled by manual valves or fully automatic controllers for a series of operations such as backwashing and forward washing. Ensure the quality of water produced by the equipment and extend its service life.

　　4Activated carbon filter

　　The system adopts shell activated carbon filters. Activated carbon can not only adsorb electrolyte ions but also perform ion exchange adsorption. Activated carbon adsorption can also increase the oxygen consumption of potassium permanganate(COD)by15mg/L(O2)drop2～7mg/L(O2)In addition, due to the adsorption effect, the concentration of adsorbed substances on the surface increases, thus also playing a catalytic role, removing pigments, odors, a large amount of biochemical organic matter in water, reducing the residual chlorine value and pollutants in water, and eliminating trihalides in water(THM)And other pollutants. Manual valves or fully automatic controllers can be selected to control backwashing, forward washing and a series of other operations. Ensure the quality of water produced by the equipment and extend its service life. Meanwhile, the equipment is equipped with a self-maintenance system and has very low operating costs.

　　5Ion softening system/Dosing system

　　R/OThe device is designed to dissolve solid substances for concentrated discharge and the utilization of fresh water, and to prevent the concentrated water end, especiallyROThe concentrated water side of the membrane module at the rear of the deviceCaCO3,MgCO3,MgSO4,CaSO4,BaSO4,SrSO4,SiSO4When the concentration product exceeds its equilibrium solubility constant and crystallizes out, it damages the inherent characteristics of the membrane element. Before entering the reverse osmosis membrane module, an ion softening device should be used or an appropriate amount of scale inhibitor should be added to prevent carbonate.SiO2The crystallization of sulfate.

　　6Precision filter

　　The precision filter is adopted to remove the residual suspended solids, non-straight particles and colloids and other substances in the influent water, so as toROThe subsequent equipment such as the system operates more and more reliably. The filter element is5umMelt-blown filter elements are designed to prevent any leakage from the upper-level filtration unit5umThe removal of impurities. To prevent entry into the reverse osmosis device and damage to the membrane surface, thereby damaging the membrane's desalination performance.

　　7Reverse osmosis system

　　The reverse osmosis device is to apply sufficient pressure to the solvent in the solution(It's usually water.)Through reverse osmosis membranes(Or it is called a semi-permeable membrane)And because this process is opposite to the direction of natural osmosis, it is called reverse osmosis.

　　Reverse osmosis can adapt to various types of raw water with different salt contents, especially in water treatment projects with high salt content, it can achieve excellent technical and economic benefits. Reverse osmosis has the advantages of increased desalination rate, high recovery rate, stable operation, small floor space and simple operation. Reverse osmosis equipment not only removes salt but also eliminates most colloids and large-molecular-weight organic substances.

　　8Ozone generator(Optional)

　　Eliminate the pollution caused by secondary pollution to thoroughly ensure the hygiene standards of the finished water.
