Since 1977, Hydrex has designed and built hundreds of water and wastewater treatment plants throughout Asia and the Middle East. Hydrex can provide pre-engineered package treatment systems for populations ranging from 100 to 200,000. We also specialize in custom designed plants based upon defined performance specifications. Our carefully designed foolproof systems incorporate the most advanced equipment, yet are easy to operate. Sophisticated, individually customized computer monitoring and data logging systems (SCADA) can be provided as well.

Our clients include respected multinational and Asian companies, many of which are repeat customers. For example:

a) In a three year period alone, one client ordered eleven packaged sewage treatment plants, ranging in capacities from 70 to 400 m³/d.
b) Another client has, to date, ordered five 4,000 to 8,000 m³/d custom designed wastewater treatment plants for their various estate developments within the region.
c) Hydrex was responsible for expanding an existing 19,000 m³/d municipal sewage treatment plant to handle a total of 40,000 m³/d. Shortly after completion, the same client awarded a 9,500 m³/d plant for another development to Hydrex.
d) Hydrex is also the only officially approved wastewater treatment plant supplier within Asia for one of the world's largest soft drink manufacturers.
