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.....
