Application of the membrane fouling simulator to determine biofouling potential of antiscalants in membrane filtration
In treatment of groundwater with reverse osmosis, the applied antiscalant can significantly contribute to the formation of biofouling, especially when legislation enforces the use of biodegradable, phosphorous-free products. As an alternative to extensive piloting, the use of the membrane fouling simulator (MFS) is proposed here to assess the biomass growth potential of different antiscalants. ...

Reverse Osmosis Chemicals
Reverse osmosis is an efficient way of purifying water but operational efficiency can only be obtained if the plant and in particular the membranes are not kept clean. If this is not the case, membranes quickly become fouled result in lower output and ultimately resulting in the costly necessity of having to replace them. Various products are available which have been developed to combat the ...

Reducing operational costs in high silica, 18,000m3/day BWRO in Arica, Chile
Abstract The desalination industry has significantly evolved in the last decade with 33million m3/day of additional desalination capacity now operating. One third is using membrane technology with 6,458 Reverse osmosis plants coming on-line. More than twice as many brackish water RO plants than sea water plants have been built since the first plants were commissioned in the late 1960’s. ...

Reusing water for industrial processes and irrigation in Saudi Arabia
Water is a scarce resource in Saudi Arabia and the public administration and private companies implement water reuse whenever possible. A reverse osmosis plant installed in the Eastern Province of Saudi Arabia helps to treat industrial waste water streams to quality levels that permit water reuse for industrial applications and irrigation. Kemira KemGuard antiscalant is used to prevent deposit ...
