In industries such as food and medicine that have extremely high requirements for water quality, integrated sterile water treatment equipment has become a key tool to ensure the purity and sterility of water quality with its advanced filtration technology and membrane separation process.
Ultrafiltration technology is an extremely important part of this equipment. The pore size of the ultrafiltration membrane is usually between 0.001 and 0.1 microns. Like a fine sieve, it can effectively intercept impurities such as large molecular organic matter, colloids, bacteria, viruses, etc. in the water, while allowing water molecules, small molecular inorganic salts, etc. to pass through. For example, when treating raw water containing large molecular substances such as proteins and polysaccharides, ultrafiltration membranes can separate these substances to prevent them from affecting subsequent processes and product quality. Its working principle is based on the pressure difference on both sides of the membrane. The raw water passes through the ultrafiltration membrane under pressure, and the impurities are retained on one side of the membrane, thereby achieving preliminary purification. The ultrafiltration process does not require the addition of chemical agents and can operate at a lower pressure. It has the advantages of low energy consumption and no phase change. It can effectively retain the beneficial mineral components in the water, making the treated water taste good and meet health requirements.
Reverse osmosis technology further improves water quality on the basis of ultrafiltration. The pore size of the reverse osmosis membrane is extremely small, generally around 0.0001 microns, which can almost block all soluble salts, heavy metal ions, microorganisms and other tiny particles. It relies on a high-pressure pump to apply enough pressure to the raw water so that the water overcomes the osmotic pressure and reversely permeates the reverse osmosis membrane, thereby obtaining extremely pure water. In food and pharmaceutical production, for the preparation of water for injection, water for oral liquids, etc., reverse osmosis technology can remove more than 99% of impurities in water, ensure that the content of microorganisms and endotoxins in the water is extremely low, and meet strict aseptic requirements. For example, in the pharmaceutical industry, water treated by reverse osmosis can be directly used in key links such as the preparation and cleaning of drugs, effectively ensuring the quality and safety of drugs.
These two processes cooperate with each other in the integrated sterile water treatment equipment to form a complete purification system. As a pre-treatment step, ultrafiltration first removes most of the larger particles of impurities and microorganisms, reduces the burden on the reverse osmosis membrane, and extends its service life; reverse osmosis, as the core of deep purification, further removes tiny soluble impurities to ensure that the water quality reaches the sterile and high-purity standards. At the same time, the equipment is also equipped with a precise pressure control system, flow monitoring system and automatic cleaning device to ensure the stable operation and long-term effectiveness of the ultrafiltration and reverse osmosis processes, and continuously provide high-quality sterile water for the food and pharmaceutical industry, promoting the healthy development of the industry.
