Evaluation of meshed tube filtration as a novel SWRO pretreatment for the removal of marine dinoflagellate Cochlodinium polykrikoides

Algal bloom has been an ongoing issue for seawater reverse osmosis (SWRO) desalination. The massive red tide that happened in the Gulf of Oman in 2008-2009 caused several SWRO desalination plants to stop operation for plugging of pretreatments and/or unsatisfactory RO feed water quality (Richlen et al., 2010). This event increased the necessity for primary pretreatment against algal bloom. Hitherto studied marine microalgae species according to desalination processes were mostly diatoms and cyanobacteria. The impacts of the marine dinoflagellate C.polykrikoides on desalination pretreatments has not been deeply investigated. In this study, the Meshed Tube Filtration (MTF) was developed and evaluated as a novel pretreatment process for C.polykrikoides removal. Experimental results showed potential of MTF on bloom control especially in the aspect of membrane fouling potential reduction.
