Veolia Water Technologies South Africa supplied a 10 m3/hour package plant to treat the boiler feed water at a natural gas-fired combined cycle power plant in Tanzania.

The company was contracted by the OEM responsible for the supply and installation of heat recovery boilers, steam turbines and other associated equipment.

“Correctly treating the water cycle within the boiler system is critical to ensure the boilers provide optimum performance over their service life in order to increase plant efficiency,” explains Kgomotso Khomo, Project Engineer, Veolia Water Technologies South Africa.  “Improper treatment of boiler feed water can result in overheating, failure to produce hot water or steam, a drop in the boiler flow rate, an overall loss of efficiency and component damage.”

Supplied as a prefabricated package solution, the plant was assembled at Veolia’s Water Techno Packages Division in Sebenza, Johannesburg, in just 12 weeks.

Veolia’s modular plants provide plug-and-play water treatment for operations with inadequate access to bulk water and wastewater treatment, or those requiring more specialised water treatment standards, with a quick turnaround time. Coagulation, flocculation, lamella clarification, sand filtration, disinfection and reverse osmosis are all standard processes in these off-the-shelf plants, while this specific boiler water applications required an additional Activated Carbon Filter in the pre-treatment phase to protect the RO membranes.

Pre-assembled and Factory Acceptance Tested at Veolia’s Engineered Systems Division, these plants comply with SANS and WHO quality levels.
