Veolia feedwater treatment package for South African GTCC plant
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 packaged water treatment plant will treat process water to the standards required by the power plant’s boilers. The company was contracted by the original equipment manufacturer (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,” explained 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,” he added.

Power Plant Cooling Towers and Cooling Water Issues - Webinar - Hot Topic Hour February 16, 2012
Power plants use significant quantities of water, mostly for cooling purposes while generating electrical energy. However, proposed rules on power plant water intakes and discharges, as well as the increasing scarcity of fresh water, will drive changes in water use and management strategies at power plants.

Nuclear Power Plant Water Treatment Webinar - Hot Topic Hour July 1, 2010
Three industry experts provided presentations for the McIlvaine Hot Topic discussion on Nuclear Power Plant Water Treatment. • The first presentation was by Gregg Poppe of Dow Water & Process Solutions: ‘Reducing Chemicals and Waste with Advanced Water Purification Technology.’ This presentation addressed the three primary stages of effective water treatment including Pre-Treatment, Roughing, and Polishing. The importance of safe, reliable, efficient, and “green” environmentally sound practices was emphasized. Ultrafiltration using Dow tubular UF membranes was highlighted as an effective pre-treatment going into RO filtration. EDI was discussed as an effective polishing procedure that eliminates the need for chemical treatments. • The second presentation was by Timothy Rittof of Veolia Water Solutions and Technologies: ‘Nuclear Power Plant Water Treatment.’ This presentation discussed various clarification processes for non-process water including river water, reclaim (grey) water, and cooling tower blowdown water. The Actiflow and Actisoft clarifiers and softeners were discussed, along with disc filters and CeraMem filters by Veolia. Also discussed were energy recovery multi-effect-evaporators for the production of fresh water using waste heat from power plants. Veolia provides more than 40 years of experience in nuclear power plant water treatment. • The third presentation was by Anthony Rossi of GE Water & Process Technologies: ‘PWR Dispersant Review & Update, OptiSperse PWR6600.’ This presentation addressed the dispersion of iron oxides in steam generator (SG) systems using the OptiSperse polyacrylate dispersant, without any sulfates or chlorides. Testing showed very high dispersion activity with very low polyacrylate dosages. The effectiveness of the treatment at reducing corrosion, and thermo-hydraulic instabilities was discussed. Advantages include improved long-term thermal performance of the SG, potential for long-term reduction in routine off-line cleaning frequency, and the long-term goal of a reduction in frequency or complete avoidance of full bundle SG chemical cleaning.
