PROXA turned to chemical free treatment methods to reduce operating costs and up-skill residents in support of enterprise development.
The Avon Peaking Power plant in South Africa – owned
by IPR-GDF Suez, Legend Power Solutions (LPS), Mitsui
and the Peakers Trust – needed a high specification
demineralisation water plant for the production of ultrapure
water suitable for gas turbines.
FATA approached PROXA to deliver a solution. As such,
PROXA designed, built and commissioned an electro
deionisation (EDI) plant as the polishing unit instead of
traditional ion exchange.
HOW PROXA ADDED VALUE
The advantage of an EDI plant is that no chemicals are
used and therefor there is no need for bulk chemical
storage on site, operational (chemical) costs are reduced
and there are no added problems associated with
waste disposal and environmental concerns. PROXA
also turned to pre-manufactured skids to minimise site
installation thereby enabling seamless integration with
the client’s civil, electrical and other mechanical works.
Demineralised water compliant for use in gas turbines
- Product flow rate 20m3/hr
- Product conductivity: 0.1 μS/cm
- Availability: 95%
