Sea Water Treatment

ETS sister company, atg, has recently delivered a skid mounted UV disinfection system for the treatment of sea water.  The system incorporates two parallel trains of three SX-635-16 in series and associated piping and valves.  The UV chambers, power and control cabinets, piping, and valves were delivered a shipping container where the influent and effluent lines could be piped direct to the container.  Each train is designed to treat 19 MGD at 40 mJ/cm2 at a transmittance of 90%.    

The process of disinfecting water with UV light is a proven technology for drinking and process water in many industries, however the high standards required by the offshore industry commanded the UV disinfection systems to be engineered way beyond the normal specification of many manufacturers  The ETS UV package comprised of six high specification, validated compact SX-635-16 reactors built from steel engineered for corrosion resistance, arranged in a duty/standby trains with integrated SPECTRA control systems, ensuring full automatic control of the disinfection process at all times.

Using microprocessor technology, SPECTRA combines many innovative features such as fully automatic start-up and shut down, multiple lamp monitoring, process interlocks and automatic quartz cleaning.  Additionally the SPECTRA control system provides data on flowrate, UV dose and intensity while the SPECTRA's integrated data logger provides performance data which can be easily downloaded to a PC or Laptop for review.

A proven track record and extensively developed technology positions ETS as the clear market leader in the offshore and marine industries in the US. Plants treating in excess of 25 MGD have been supplied by ETS sister company atg, whose breakthrough UV systems have been designed and engineered to meet the exacting standards required by the off-shore industry.  Additionally ETS can offer a full range of ATEX UV systems for operation in Hazardous Zones 1 & 2 and have experience in designing UV equipment to NORSOK, NiPH, GOST & US EPA UVDGM specifications.
