  In membrane treatment plants, mineral build-up usually does not cause a sudden problem. Instead, operators may notice a slow drop in water flow, more frequent cleaning and extra work for maintenance teams. For plants in the UAE and GCC treating seawater, brackish water or water for reuse, these problems can affect daily operations and production planning. The key question is how treatment chemicals, concentrated antiscalants and RO vessel design can each help deal with these challenges in different ways. The Problem: Scaling Is More Than a Membrane-Surface Issue Minerals such as calcium carbonate, sulfate and silica can accumulate on RO membranes, affecting water production and increasing cleaning needs. Repeated maintenance can interrupt plant schedules, while conventional RO arrangements may also involve numerous vessels and associated components that require considerable space. For desalination and water-reuse facilities, controlling mineral deposits while considering equipmen...

  When we talk about desalination plants, both the operation and performance of the plant highly depend on the membranes. To keep those membranes, especially RO membranes, in an efficient and healthy condition with a long span of service life, RO membrane cleaning chemicals are used. With such chemicals, it is easy to keep the membranes clean with fewer mineral deposits on the surfaces. Read this blog to explore this vital chemical.   Why RO Membrane cleaning chemicals are necessary?   Almost every reverse osmosis feed water has a distinct ionic composition. So, it is obvious to get different kinds of scales which may get deposited on the membranes, if proper and good quality membrane antiscalant chemicals are not used. The process of reverse osmosis indeed gets impacted negatively by some impurities which result in the building up of the RO membranes at the time of operations with minerals, suspended solids, microorganisms etc. All these deposits can indeed resu...
