Reverse osmosis plants are built to deliver consistent water treatment, but membrane performance can change over time. Minerals can form scale, organic matter can create fouling, and biological growth can affect the membrane surface. When these problems develop, the effects can be noticeable. Water production may fall, operating pressure can increase, and cleaning may become more frequent. Good membrane management therefore starts before performance drops significantly. The right chemical programme can help prevent deposits from forming, while suitable cleaning methods can restore membranes when fouling has already occurred. Protecting Membranes Starts with Understanding the Problem Not all membrane deposits are the same. Calcium carbonate, calcium sulphate, silica, organic matter and biofilm can all affect RO membranes, but they do not respond to exactly the same treatment. Choosing a chemical without understanding the cause can result in ineffective cleaning or unnecessary downtime. ...

Modern distribution networks need to respond quickly when faults occur. A temporary fault caused by lightning, vegetation contact or another short-duration event does not always require a long outage, yet conventional protection arrangements can leave customers disconnected until the circuit is manually restored. This is where the recloser becomes an important part of distribution automation. An automatic circuit recloser can detect a fault, interrupt the circuit and then attempt to restore power automatically according to a programmed reclosing sequence. If the fault has cleared, service can resume without requiring manual intervention. If the fault remains, the protection system can isolate the affected section. Chardon Group’s epoxy solid recloser is designed for overhead distribution applications and combines vacuum interruption, epoxy insulation, integrated sensing and programmable protection functions. Current product information lists voltage classes up to 38 kV and testing in ...
