Cooling Tower Side Stream Desalination

Cooling Tower Side Stream Desalination plant

THE CHALLENGE

Kriel Power Station needed to quickly increase the cycles of concentration on their cooling towers to reduce excessive effluent generation.

OUR SOLUTION

Our innovative process design and rapid construction programme meant that we were able to install a desalination system on the cooling tower feed water relatively fast. The System reduced the intake of fresh water and the effluent generation.

HOW PROXA ADDED VALUE

The plant was delivered and commissioned within a few months

FEED WATER

Softened cooling cycle water

PRODUCT WATER

Feed to cooling towers.

PERFORMANCE TARGET

  • Flow rate 4500 kl/day
  • Conductivity < 200 pS/cm
  • Availability 90%

PROCESS

  • Multi-media filtration
  • Reverse Osmosis
  • Back wash waste settling column

PROCESS RELIABILITY

By Placing highly experienced personnel at the site we were able to deliver up-time and quality to the most stringent requirements. This was underpinned by our proven capabilities to design, implement, operate and maintain critical water treatment infrastructure in various process industries.

PROCESS INNOVATIONS

Our engineers took an holistic approach to optimise implementation at the client’s site. In this instance, working within the physical constraints of the site.

PLANT COMMISIONED

2009

CONTRACT DURATION

PROXA was responsible for the operations and maintenance of the plant for a period of 24 months. We installed our propriety Q-TRAK® remote monitoring system for the plant and provided technical support
