Algae have long been an issue impacting desalination plant operation in areas prone to algal blooms or where macroalgae (seaweeds) and detritus became dislodged from the seabed. Previously and still today, operators and designers may elect to turn down production or shut down SWRO plants, if contract obligations allow, when blooms are infrequent or of short duration. Alternatively, in areas subject to frequent and prolonged blooms, additional pretreatment such as conventional dissolved air flotation (DAF), hitherto designed for brackish water applications, began to be employed as early as 1995. The unprecedented 2008/2009 bloom of Cochlodinium polykrikoides in the Gulf of Oman and the Gulf1, brought algal blooms to the fore in the desalination industry. SWRO plant shutdowns were up to four months long as pretreatment processes struggled to remove the increased biomass and produce the required RO feedwater quality. Apart from a few exceptions, thermal desalination plants cont.....
