Reverse osmosis desalination plants employ chemical injection systems to preserve the reverse osmosis membrane, restrict biological development, improve the quality of the treated water, and stop corrosion. Chlorine is one of the most often utilized chemicals in plant injection. Prior to the reverse osmosis stage, microorganisms in the supply water are disinfected and killed using chlorine. Usually, a chlorine injection occurs after the reverse osmosis pump but before the last storage tank. Plant injection systems may also use pH neutralizers, sediment inhibitors, corrosion inhibitors, and bacteria inhibitors in addition to chlorine. The raw water's composition and each plant's unique treatment needs determine which chemicals are utilized. In order to control the flow and concentration of injected chemicals, chemical injection is usually carried out utilizing automatic control systems or precision pumps. Water analysis and treatment needs are used to calculate the injection rate and chemical content.
Chemical injection must be closely monitored to ensure intended outcomes are obtained and the safety of the treated water is maintained. Monitoring flow and pressure, keeping an eye on chemical concentrations in treated water, maintaining equipment on a regular basis, keeping records, and checking performance on a regular basis are all examples of good chemical injection procedures. In reverse osmosis desalination plants, chemical injection must be performed in compliance with national and international environmental and health regulations. To guarantee the efficacy of treatment and the security of treated water, these systems must be carefully installed and maintained by qualified operators and technicians.
