According to the International Desalination Association, an estimated 18,000 desalination plants are spread across 150 countries, with reverse osmosis (RO) being one of the leading membrane-based technologies to remove dissolved salts and other impurities from oceanic or underground sources.
Desalination plants (by definition manufacturing facilities) are continuously trying to improve performance or efficiency. The major operational issues of today’s desalination facilities involve day-to-day monitoring of the complete process and careful preventive maintenance.
Hach® designs and builds a full range of online water analyzers that can be used to achieve process transparency at all stages of the desalination process, particularly for reverse osmosis (RO) water such as Sea Water RO, and Brackish Water RO.
For over 85 years, Hach has offered water analytical instruments for process, lab and handheld applications. Hach makes water analysis better, faster, simpler, greener and more informative.
With Hach, Desalination plants can:
Naturally occurring constituents in sea water are often present in such quantities that they require additional actions for removal in the desalination process, in order to meet quality requirements for human consumption. Unwanted residues or by-products can result from the carryover of these constituents to the RO stage.
pH Conductivity/TDS/Salinity Suspended Solids Turbidity Chlorine ORP Oil in Water Total Organic Carbon
Feed water pretreatment in desalination facilities is necessary to improve the quality of the feed water to the level of reliable operation of the RO membranes.
pH Conductivity/TDS/Salinity Turbidity Total Organic Carbon
Uncontrolled fouling or clogging of the membranes, leads to increased maintenance, higher energy costs and a short membrane life. Online monitoring of both chemical and biological key parameters allows you to take your process to the next level, while cutting back on unwanted expenses.

The quality of the distributed water is of paramount importance as it concerns human health. Drinking water quality criteria often requires a large set of physicochemical and biological analysis, which are conducted prior to distribution by the local authority.
