  • How big is the distributed energy opportunity for water and wastewater utilities?

    Energy costs for water utilities are large, and growing Energy is a significant cost for many water utilities, and costs are growing as more energy-intensive forms of water supply, including desalination, are being used. Energy is typically the second-largest utility budget item in developed countries, after labour. In many developing countries, energy can account for 70% or even more, of ...

  • TOC analyzer for airports

    During winter, de-icing processes at airports necessitate storm water and de-icing water management. Especially due to adhesive (sticky) substances, strongly fluctuating concentrations and a lot of chemicals, the monitoring systems itself must be tailor-made to fight this water analysis challenge. LAR 's ...

  • Understanding the 3 Types of Arsenic Removal Used for Wastewater

    With the onset of the Industrial Revolution and the development of internal combustion engines and new manufacturing technologies, fresh water became an essential raw material not only for production, but for cooling purposes in manufacturing processes. However, when fresh water is used in an industrial process, it creates industrial wastewater composed of a variety of chemicals and other raw ...

  • Looking Beyond Chemical Water Treatment Case Study

    When you think of an environmentally friendly company, a steel processing plant does not typically come to mind. However, Stripco Inc. of Mishawaka, IN, a manufacturer of production-ready, cold-rolled steel coils, is the exception. In August of 1995, Stripco made a wise decision that also proved to be cost-effective and environmentally- friendly when they installed a Superior Environmentalist ...

  • Catalyst-Based Non-Chemical Water Treatment

    Catalyst-Based Device Reduces Calcite Buildup, Requires Minimal Maintenance According to the US Geological Survey, more than 85 percent of the United States has hard water.1 In plumbing, hard water leaves calcite deposits that restrict water flow by occluding pipes. In water heaters, calcite coats heating elements, causing them to overheat and eventually fail. Standard approaches to ...

  • In Situ Physical/Chemical Treatment for Ground Water and Leachate

    The main advantage of in situ treatments is that they allow ground water to be treated without being brought to the surface, resulting in significant cost savings. In situ processes, however, generally require longer time periods, and there is less certainty about the uniformity of treatment because of the variability in aquifer characteristics and because the efficacy of the process is more ...

  • Whitepaper: Chemical-physical Water Treatment, Filtration and Flocculation

    Introduction In water treatment plants chemical-physical processes play an essential part in the process chain. They are successfully employed in the pre- and post-treatment of waters of different origins, as well as of other process liquids. In this regard the removal of particles by filtration is a central step. Classical filtration processes are used for particles ranging from ...

  • Sustainable wastewater treatment chemicals in a dairy

    Problem/Definition Atana Ltd has been tasked in reducing sludge generation produced at the sites effluent plant by introducing a new chemical regime. This would bring considerable savings on their daily running costs; reduce the need for hazardous substances and prevent any corrosive issues through the removal of inorganic chemicals. The plant also has consent issues with FOG and ...

  • Ex Situ Physical/chemical Treatment for Ground Water, Surface Water, and Leachate

    The main advantage of ex situ treatment is that it generally requires shorter time periods, and there is more certainty about the uniformity of treatment because of the ability to monitor and continuously mix the ground water. Ex situ treatment, however, requires pumping of ground water, leading to increased costs and engineering for equipment, possible permitting, and material handling. ...

  • Integrated process control for recirculating cooling water treatment in the coal chemical industry

    This work focused on the integrated process of the recirculating cooling water (RCW) treatment to achieve approximate zero emission in the coal chemical industry. The benefits of fractional and comprehensive RCW treatment were quantified and qualified by using a water and mass balance approach. Limits of cycle of concentrations and some encountered bottlenecks were used to ascertain set target ...

  • Chemical monitoring strategy for the assessment of advanced water treatment plant performance

    A pilot-scale plant was employed to validate the performance of a proposed full-scale advanced water treatment plant (AWTP) in Sydney, Australia. The primary aim of this study was to develop a chemical monitoring program that can demonstrate proper plant operation resulting in the removal of priority chemical constituents in the product water. The feed water quality to the pilot plant was ...

  • Perfluorinated chemicals (PFCs) in water purification plants (WPPs) with advanced treatment processes

    A series of perfluorinated chemicals (PFCs) surveys were conducted in two water purification plants (WPPs) having ozonation and granular activated carbon (GAC) filtration processes. In each plant, six different processes samples (source water, influent, coagulation-sedimentation effluent, ozonation effluent, GAC filtration effluent, and final tap water) were collected for two times and eight PFCs ...

  • Electrocoagulation in Water Treatment

    Although electrocoagulation (EC) is an evolving technology that has for the past 100 years been effectively applied in industrial water treatment, the paucity of scientific understanding of the complex chemical and physical processes involved as well as the limitations (in terms of size and cost) of the needed power supplies in the past, have curbed large scale applications and hindered progress. ...

  • Efficient Waste Water Treatment

    Clean drinking water is an essential need of mankind. Often surface water like rivers or lakes is used as drinking water source. To prevent these resources from pollution the effective treatment of waste water is a must. For example in China 75% of discharged waste water is coming from pulp and paper, textile and dyeing industries. To run a waste water treatment plant in the most efficient way ...

  • Water treatment case study

    Wastewater is any water that has suffered in quality by human intervention. Often, wastewater is being treated for re-use as drinking water or for other purposes. As high levels of nutrition are available in these waters, algae may grow rapidly as well as other micro-organisms such as bacteria. Algae can compete for nutrients against the bacteria in charge of sludge reduction and can also clog ...
