Scale reduction and cleaning techniques during direct contact membrane distillation of seawater reverse osmosis brine • Reduction of distillate ﬂux is primarily caused by precipitation of CaCO3 and CaSO4. • Changing of pH in hot bulk brine provides early indication of scaling formation. • Inline cartridge ﬁltration improves DCMD operational time and water recovery. • Antiscalant prolongs DCMD operational time by mi Desalination 374 (2015)
Innovations in the inhibition and cleaning of reverse osmosis membrane scaling and fouling Scaling and fouling of membranes are an on-going performance issue for most plants This presentation outlines innovations in speciality chemicals designed to inhibit membrane scaling and fouling and to clean membranes where deposition has occurred. There is an increasing trend to treat recycled wast Desalination 238 (2009)
RO plant experiences with high silica waters in the Canary Islands In many arid regions of the world, the shortage of good quality feed-water is forcing plant owners either to run their membrane systems with undesirable levels of silica or to restrict recovery rates.
