Thin film composite type positively charged nanofiltration membrane for separation of aqueous streams and nuclear effluents
Thin film composite type positively charged nanofiltration membrane developed by in situ polymerisation of functionalised polyethyleneimine and acid chloride has been used in various aqueous stream separations. The membrane contained fixed quaternary ammonium moieties which contributed to its positive charge. The membrane was tested for its performance in single solute feed systems containing ...

Selection and design criteria of supported liquid membrane for the treatment of rad-waste
Supported Liquid Membrane (SLM) is an emerging trace metal pre-concentration technique. It has the ability to decontaminate radionuclides even from lean secondary effluent. SLM can be considered as a part of process intensification, which implies a closed loop operation. It has reduced space requirement as well as minimised secondary effluent generation and the number of unit steps. Proper ...

Radioactive wastewater treatment using a mixture of TANNIX sorbent and VARION mixed bed ion exchange resin
A wastewater treatment system has been developed by using a mixture of ammonium-insoluble tannin (TANNIX, this is the trademark of an adsorbent made by Mitsubishi Nuclear Fuel Co. Ltd) and mixed (strong acid cation exchanger and strong base anion exchanger) ion exchange resin (MIX) for the selective separation of transuranium isotopes, including Pu, Am, Cm, and U, as well as fission and ...

Dynamic perspective on the relation between environmental policy and eco-efficiency: the case of wastewater treatment, waste and energy efficiency in the Dutch paper and board industry
The relation between environmental policy and innovation is complex. This paper aims to gain insight into the way accumulation of policy measures, or in other words, the increase of policy pressure, affects research activities and eco-efficiency. Three environmental domains have been researched for the Dutch paper and board industry: wastewater, waste and energy. Three trends (19802003) are ...

Working with energy and mass balances: a conceptual framework to understand the limits of municipal wastewater treatment
At present all municipal waste water treatment plants (WWTPs) are energy consumers. Electrical energy requirements for oxygen transfer are large in secondary biological systems. Nevertheless, from a thermodynamic point of view chemical oxygen demand (COD) is an energy source. Combustion of every kilogram of COD releases 3.86 kWh of energy. In this manuscript some measures are presented, from a ...

Pendleton wastewater treatment plant biogas application - Case Study
About the Project In 2011, the City began work on a cogeneration facility as part of the upgrades at the Waste Water Treatment Plant. The city was given us the ability to convert solids arriving at the Waste Water Treatment Plant into useful energy and high quality fertilizer. The system was designed to generate about 750,000 kWh per year, which translates into about $50,000 annually in saved ...

Monitoring air quality in sewage treatment plants - Case Study
Monitoring air quality in sewage treatment plants Wastewater and sewage emit toxic gases such as hydrogen sulfide (H2S) and volatile organic compounds (VOC). To prevent the exposure of workers and residents to harmful effects, changes in the concentration of pollutants in the air must be monitored. VEOLIA, a leading company in the water, waste treatment, and energy sector, wanted an ...

Improving the energy efficiency of wastewater treatment in Mexico case study
Kemira participated in the delegation of the Finnish Environment Institute Syke to Mexico, where a memorandum of understanding for cooperation in the water sector was signed between the two governments. Mexico’s National Water Commission CONAGUA is the signing party in Mexico and an important customer for Kemira, who has been supplying coagulants for potable water treatment for Mexico City ...

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 ...

Optimizing air flows to aeration basins – Case Study
As a result of clean energy mandates and the rising cost of energy, wastewater treatment facilities around the country are retrofitting their instrumentation to run highly efficient, cost-effective, clean facilities. To reduce emissions and produce clean energy, solid wastes are often digested in large digester tanks to reduce the volume of waste (sludge) and produce more biogas, which is then ...
