  • Oxygen Monitors now Required for Nitrogen, Argon, Helium, and CO2 use in Denver

    The Colorado city of Denver recently passed a new law that requires facilities that use insert gas to install oxygen deficiency monitors wherever these gases are used in excess of 100 pounds. Learn what the new law requires from businesses and how an oxygen sensor protects your employees, your business, and your peace of mind.  What Denver's New Law Requires  The law ...

  • 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 ...

  • Zhuhai --a membrane based water treatment plant

    The Facility At the time it was built, the Guangdong Zhuhai Power Station set a number of firsts for China. Not only was it the largest thermal power plant in terms of unit size , it was the first to use Reverse Osmosis Water Treatment and it was the first to be financed without a multilateral or government guarantee. Zhuhai was also EPC Mitsubishi Heavy Industries’ first turnkey ...

  • Ozone Based WasteWater Treatment

    The Australian Water Association held an international conference on 'Onsite and Decentralized' waste water treatment systems in Benalla, VIC. This was the abstract presented by Kyle Greene, Seair Canada Head of Research and Development. These portable wwtps are used in the extremes of northern Canada oil, gas and mining camps. Featuring: Heavy duty steel container, industrial weather coated, ...


  • Waste Water Treatment Plants

    In 1980, Los Angeles began exploring alternatives to control the H2S concentration in the digester gas produced at the Hyperion Waste Water Treatment Plant (WWTP), which treats nearly 420 MGD, wastewater generating over 475 tons of raw sludge per day. The digester gas H2S concentration had to be controlled so that the SOx emissions from the on-site combustion of the gas could be kept within ...

  • Produced water treatment technologies

    Abstract Produced water is a complex mixture of organic and inorganic compounds and the largest volume of byproduct generated during oil and gas recovery operations. The potential of oilfield produced water to be a source of fresh water for water-stressed oil-producing countries and the increasing environmental concerns in addition to stringent legislations on produced water discharge into ...

  • 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 ...

  • Ozone in Cooling Water Treatment

    When commercial ozone generators were first introduced for cooling water treatment, they were marketed as a stand-alone treatment, a cure-all or panacea. We now know this is not the case. Because there have been many misconceptions regarding ozone, this article is intended to review the basics of ozone, its true capabilities and limitations, and its potential benefits in cooling water treatment ...

  • 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. ...

  • Water Quality & Treatment Centers

    A look at the quality of water and the importance of inspecting the integrity of water treatment centers. Water…clear…cold…refreshing. It’s often your “go-to” beverage for quenching thirst after a vigorous activity. We are very fortunate that often within arm’s reach, rests a glass of water. Without hesitation or worry, you can pick it ...

  • Energy requirements for waste water treatment

    The actual mathematical models describing global climate closely link the detected increase in global temperature to anthropogenic activity. The only energy source we can rely on in a long perspective is solar irradiation which is in the order of 10,000 kW/inhabitant. The actual primary power consumption (mainly based on fossil resources) in the developed countries is in the range of 5 to 10 ...

  • MIEX Resin Water Treatment Process

    The MIEX®1 Resin process was developed in Australia for the removal of natural organic material in water treatment. This novel, truly continuous ion exchange process, is based on the MIEX® resin – a micro size, macroporous, strong base, magnetic ion exchange resin. The resin was specially developed for this application and optimised for reversible removal of negatively charged organic ions. The ...

  • Microbial Control and Sanitization of Membrane-Based Pure Water Treatment Systems

    Introduction Today's high technology water purification systems are designed to remove many types of impurities. One of the most difficult to deal with is microbiological contamination. Microbial growth in a water system presents two problems: it not only reduces water quality, but if left unattended, the problem can 'grow' to reduce system performance and life. Biofouling can cause a decrease ...


  • Community-based wastewater treatment systems and water quality of an Indonesian village

    This paper examines the impact of community-based water treatment systems on water quality in a peri-urban village in Yogyakarta, Indonesia. Water samples were taken from the wastewater treatment plants (WWTPs), irrigation canals, paddy fields and wells during the dry and wet seasons. The samples were tested for biological and chemical oxygen demand, nutrients (ammonia, nitrate, total nitrogen ...

  • Water Treatment Optimization - Case Study

    Drinking water treatment in North America has stringent requirements for effluent water quality, with a great amount of attention being drawn to the presence of hazardous disinfection by-products (DBPs) persisting through water distribution systems. The operation of water treatment plants involves addition of various mixing agents to help with coagulation and settling of organics in the raw water ...

  • The mystery of electronic water treatment unveiled

    The problems of scale are well known to those living and working in "hard" water areas. Scale is the undesirable consequence of water supplies becoming super-saturated with dissolved minerals.  These problems are of greater significance if found in industrial water systems and commercial buildings. Scaling problems commonly occur, even in "soft" water areas, when a fluid stream is ...
