Cooling Tower Make-up From Ashwater

Cooling Tower Make-up From Ashwater at Camden Power Station

THE CHALLENGE

Eskom’s Camden Power Plant had to implement environmental protection measures to rehabilitate their ash dam.

OUR SOLUTION

PROXA’s innovative process design and rapid construction programme saw the plant upgrade ash water to cooling tower feed. This solution simutaneously prevented surface water pollution and reduced pressure on valuable raw water supplies

HOW PROXA ADDED VALUE

The plant was delivered and commissioned within a few months

FEED WATER

Ash water

PRODUCT WATER TARGET

Feed to cooling towers

PERFORMANCE

  • Flow rate 4500 kl/day
  • Conductivity < 100 microS/cm
  • Availability 90%

PROCESS

  • Multi-media filtration
  • Metal oxidation
  • Granular activated carbon
  • Reverse Osmosis

PROCESS RELIABILITY

In dealing with variable feed streams such as heavily contaminated industrial effluent, process robustness is of critical importance.

ENVIRONMENTAL PROTECTION

PROXA is responsible for the operations and maintenance of the plant for a period of 8 years. We installed our proprietary Q-TRAK® remote monitoring system for the plant and provided technical support while rehabilitating the dam.
