    Water treatment for power plants

    The process of electricity generation from fossil fuels such as coal, oil and natural gas is water-intensive. Between 40-50% of all water abstracted and used in developed countries is used in the generation of electricity. Thus, a reliable, abundant and predictable source of raw water supply to a power plant is a critical factor in site selection. Water supplies are required to provide various process waters for the following essential main purposes such as make-up water, cooling water for steam turbine condensers, and auxiliary plant cooling water.

    The primary application of modern water treatment technology is to maintain the integrity and performance of the power plant. Critical plant applications have water purity or conditioning requirements that must be adhered to for safe, reliable and efficient power generation.

    Experience has shown that integration of water technology treatments with power plant design can be very important in reducing operational problems and component failures 

    At power plant worldwide there are increasing limitations on water availability and environmental restrictions on discharges. This is expected to promote measures for water conservation and to have an increasing influence on water treatment decisions. At power plant, the recycling of internal wastewater streams can extend from the recovery of individual high-quality waste streams, which can be reused either directly or after only limited treatment, through to the development of fully integrated water/wastewater treatment systems for zero liquid discharge. However, the application of reuse schemes requires site-specific assessment, as not all waters may be viable options for recovery.

  • APHA Color #3020

    Measurement of APHA color either on-line or in a laboratory setting using a photometer. Background: APHA is sometimes referred to as the Platinum Cobalt (Pt/Co) or Hazen scale. Also referred to as a “yellowness index”, the APHA color scale is a common method of comparison of the intensity of yellow-tinted samples to assess the quality of liquids that are clear to yellowish in color. Originally developed to determine the purity of municipal water supplies, it is now used as a metric for purity in the water, chemical, oil, plastics, and pharmaceutical industries. APHA color quantifies the appearance of trace amounts of yellowness, which is a visual indicator of product degradation due to exposure to light or heat; the presence of impurities and negative effects of processing. As such APHA color is often used as a product release specification. APHA is a single number yellowness index. The units are based on a dilution of a 500ppm solution of PtCo.

    Docupak LLC, a full service marketing company headquartered in Alabaster, Alabama, has reduced chemical usage by a third and removed all scale from its cooling tower at its plant after installing the patented, award-winning Scalewatcher computerized, electronic water-conditioner from Scalewatcher North America. In addition there are no longer signs of algae growth on the cooling tower louvres. Founded in 1998, Docupak, the operating name of Document and Packaging Brokers Inc., develops and distributes materials for businesses nationwide. In addition to its headquarters in Alabaster, Alabama, the company also operates a further plant in Alexandria, VA and has sales offices in Atlanta, Chicago, Cincinnati, Dallas, Los Angeles, Tampa and Washington, D.C. Aware that health agencies continually draw attention to the risks of limescale and algae in cooling towers and wanting to reduce the use of chemicals in the cooling tower, Plant Manager, Anthony Kinstley decided to install the Scalewatcher electornic water-conditioner through local dealer, Al Chatham of Water Processing and Well Supply in Harpersville, Alabama. An industrial Scalewatcher was installed on to the water-feed line to the building and then a further unit was specifically fitted on to the recirculation line of the cooling tower. “Since using the system the scaling on our cooling tower has been eliminated and we currently use only a third of the original chemicals intended for the water treatment within our system”, said Anthony Kinstley. Many air conditioning and refrigeration plant systems are water-cooled. The heat generated by cooling coils is removed by water, which is passed through a water-cooling tower. These are recirculating systems, which operate at temperatures ideal for bacterial and algae growth, and have plentiful supplies of nutrients. In cooling towers, temperature, water hardness, pH, scale and corrosion are all factors, which increase the chance of biofilms, algae and Legionella colonization. The environmentally friendly Scalewatcher provides a permanent solution to hard water problems without the need of chemicals, salt or maintenance. It works by producing a varying electronically applied force field, induced by a coil wrapped around the outside of the pipework, which keeps the minerals in suspension and thus prevents limescale forming. The water’s increased solubility enables it to dissolve existing scale, which is gradually washed away. “Scalewatcher has proven itself to be highly effective. I would highly recommend this product and service without limitation,” concluded Antony Kinstley. Scalewatcher models are based on continuous research and over 25 years experience and expertise as market leaders in electronic scale control with countless units sold worldwide. The patented Scalewatcher systems are capable of treating pipe sizes from one to 120 inches. All Scalewatcher systems come with a full performance guarantee and are shipped throughout North America.
