Guangdong cosmetic reverse osmosis water treatment equipment failure author of the article: Cosmetics beauty who is essential, there is now a lot of cosmetic industry on the development of the cosmetics market. The water used in cosmetics is to remove the strong dielectric, but also to remove weak electrolytes such as silicic acid and carbon dioxide that are difficult to remove in the water to a certain extent. The salt content of pure water is below 1.0mg/L, and the conductivity is less than 0.2us/cm. Cosmetic reverse osmosis pure water equipment is a more advanced and energy-saving effective membrane separation technology today. The cosmetic reverse osmosis pure water equipment uses membrane separation technology, which can effectively remove charged ions, inorganic substances, colloidal particles, bacteria and organic substances in the water. In the long-term operation of cosmetic reverse osmosis pure water equipment, such various equipment failures cannot be avoided. In this way, we must find out various failures and take relative measures to eliminate equipment failures. Some failures are not visible. Sometimes the equipment suddenly stops during use, and restarting is forbidden. You must find out the cause and restart the reverse osmosis system when the reverse osmosis system is not endangered. Today, the environmental protection editor will show you how to troubleshoot reverse osmosis purified water equipment. There are three main types of failure phenomena of cosmetic reverse osmosis pure water equipment systems: reduced water permeability, increased salt permeability (decreased salt rejection rate), and increased pressure drop. However, there are many reasons for these failures, and we should try our best to find out from these failures. Find out the essence of the problem, so as to implement countermeasures such as overhaul and maintenance as soon as possible. The main measures of reverse osmosis purified water equipment system troubleshooting 1. Cosmetics reverse osmosis purified water equipment verification instrument operation includes pressure gauges, flow meters, pH meters, conductivity meters, thermometers, etc., and recalibrate if necessary. 2. Re-check the operating data of cosmetic reverse osmosis purified water equipment to check the changes in operating records, flux and desalination rate, taking into account the influence of temperature, pressure, feed water concentration, membrane age, etc. on yield and desalination rate. 3. Possible mechanical and chemical problems in the evaluation of cosmetic reverse osmosis purified water equipment. Mechanical problems are mainly O-ring damage, salt water seal damage, pump damage, pipeline and valve damage, and inaccurate instruments. The chemical problem is that the acid is not properly added. High doses of acid will damage the membrane or cause sulfate-based fouling (if sulfuric acid is used), and low doses will cause carbonate or metal hydroxide-based fouling or pollution; two It is improper addition of scale inhibitor. High dosage may cause pollution, and low dosage may cause scaling. 4. Cosmetic reverse osmosis purified water equipment analyzes the changes in the chemical conditions of the feed water. Compare the current feed water analysis with the design benchmark data. The changes in the chemical conditions of the feed water will increase the pretreatment or update the original pretreatment. Equipment requirements. 5. Identification of pollutants in cosmetic reverse osmosis purified water equipment. One is to analyze the inorganic components of the feed liquid, brine and product liquid, total organic carbon (TOC), turbidity, pH, TDS, total suspended solids (TSS), SDI and Temperature, among which the measurement of SDI, TSS and turbidity can provide the basis for particulate matter pollution, and the measurement of TOC can predict the pollution tendency of organic matter; the second is to immerse and analyze the feed cartridge filter (the preferred method) or SDI filter Filter pad. 6. Choose a suitable cleaning program for cosmetic reverse osmosis purified water equipment. In the selection of a cleaning program, the following factors should be considered: the type of membrane and the compatibility of the cleaning agent selected, the requirements of the cleaning equipment, the structural materials of the system, and the pollution Identification etc. Environmental Protection Engineering Co., Ltd. is a professional water treatment equipment production company. The water equipment we produce adopts advanced water production technology to ensure the water quality and stable operation of the equipment.
