The client was in need of both a raw water and wastewater treatment system for its new 1,100-megawatt (MW) natural gasfired combined cycle power station that was being built to replace an existing 400-MW coal-fired plant that had been decommissioned previously. Veolia Water Technologies was contacted to engineer, procure and supply a 6,000 gallons per minute (GPM) raw water treatment system and a 1,200-GPM wastewater treatment system.
A wide range of industrial operations rely on cooling systems to function. And, in turn, these systems require cooling water to function. So, it stands to reason that a wide range of water treatment issues need to be considered and addressed so that cooling water system upsets are avoided and everything continues to run as it should. Oftentimes, an efficient industrial operation depends on efficient monitoring and treatment of cooling water.
Stricter environmental policies and regulations worldwide are changing how industry approaches all aspects of business. Likewise, EU (European Union) environmental policies governing air, soil, and water quality have become progressively stringent.
These policy changes affect the power industry’s balance of meeting growing European energy demands with compliance to environmental standards. In order to conform with EU standards specific for flue gas, a coalfired generation plant (at the time owned by Endesa, Italia, S.p.A.) in Monfalcone, Italy, undertook the measure of installing a state-of-the-art FGD (flue gas desulfurization) system at their facility. This system would remove SO2 (sulfur dioxide) from the emissions for the 336 MW coal-fired power station.
The South Coast Steam Power Plant, Puerto Rico, decided to replace an old, antiquated ion exchange-based demineralization plant with a membrane-based demineralization system.
Pumps are all too frequently one of the most overlooked and abused pieces of equipment in process automation, yet nothing moves without them and a process becomes inefficient when they don’t operate properly or completely shutdown.
Ammonia is used as a cleaning and bleaching agent in the production of fertilizers, plastics, explosives, and many other products.
Glendale Heights Wastewater Treatment Plant discharges treated water to the East Branch of the DuPage River in Illinois.
In 2010, one of the Power Plants of Puerto Rico Electric Power Authority (PREPA) faced a crisis due to biological growth in their power plant’s cooling tower. The plant was using straight hypochlorite, which was not effective at controlling biological growth.
Multiple methods of dealing with waste stream discharges are examined in light of the recent clampdown on industrial processes. By Brad Buecker, process specialist, Kiewit Power Engineers
