  • Economics of tiny thermal power plants

    Thermal power plants is the main source of energy and electricity in India and almost all countries of the world. Most of the giant thermal power plants have capacity of 500MW to 1000 MW. Investment in such giant thermal power plants is Rs 100 million per MW including transmission lines and distribution lines. ( 60 rupees = 1 US$, MW=1000KW). So 1000MW thermal power plant costs Rs 100 million/MW ...

  • Mixers and Flowmakers: Mixers at BNR plant in Borås, Sweden

    Borås Treatment Plant, the Gässlösaverket, is situated at the river Viskan which is also the recipient. The plant is the largest single discharge to the Viskan, and since the water does not pass any lakes on its way to the sea, the reduction of nitrogen is small. Due to requirements with regard to the reduction of nitrogen discharge set out by the Swedish environmental authorities, the Borås ...

  • Common environmental infrastructure: case study on the management of common effluent treatment plants

    The concept of common environmental infrastructure including common effluent treatment plants (CETPs) became popular in India due to several driving forces. A large number of small and medium enterprises located in industrial agglomerate joined hands in setting up such facilities with financial assistance from government. A study is made on the management of eight CETPs located in different ...

  • Molybdenum(VI) removal by using constructed wetlands with different filter media and plants

    The efficacy and capacity of vertical-flow wetland filters on molybdenum (Mo) removal from wastewater was examined, employing reed (Phragmites australis) and cattail (Typha latifolia) as well as different adsorption granular media. Humus, cinder, modified cinder, as well as pyrite were used as filter media. A synthetic effluent with different concentrations of Mo(VI) at ...

  • Solving waste oil management and removal problems in power generating plants

    If your plant is like most, it is doing a good job of preventing oily water waste and waste oils from escaping into the environment. But at what cost? As labor resources dwindle, operating and maintaining drainage systems, oil separators, and sometimes inadequate oil removal equipment is expensive. Paying higher than needed costs for waste oil disposal, filtration and water treatment due to these ...

  • Invasion of the non-indigenous nuisance mussel, Limnoperna fortunei, into water supply facilities in Japan

    The aquatic nuisance mussel, Limnoperna fortunei, arrived in Japan before 1987 possibly with the Asian clam imported as food from mainland China. Now the mussel’s distribution has spread to two river systems in central Japan. Water authorities reported several cases of damage caused by L. fortunei. Most cases of damage were caused by dead mussels clogging small diameter pipes for raw water ...
