The Global Environment Centre Foundation (GEC) is an entity that supports the UNEP’s International Environmental Technology Centre (IETC), based in Japan. GEC is dedicated to the transfer of environmentally sound technologies, in both developing countries and countries with economies in transition. The foundation aims to contribute to Japan’s international efforts on the environment, sharing project collaborations as well as promoting Japan’s rich conservation knowledge and experience in developing nations.
In-situ transestrification is a method by which cell membranes disintegrate by disrupting the phospholipid bilayer structure of biomembrane. The reaction transforms fatty acids found in wastes to methyl esters a valuable feed used in the production of high-value biodiesel fuels. Additionally the extraction of fatty acids in cell membranes results in the solubilization of cell contents due to disintegration of the membrane. Recycling this solubilized sludge back to an aeration tank will reduce the net sludge production.
The RD 1 Water Filtration System is a portable modular precision engineered water treatment system designed for use in remote or inaccessible locations and as a backup high quality water provision source for communities whose access to regular supplies of potable water may be limited by environmental or infrastructural factors.
Techase has developed a Special Multi-plate Screw Press which is adaptable to deal with sludge from a variety of industries such as petro chemistry paper amyloid chemical blue-green algae pectin wastewater inorganic material and so on. For instance if the filter press is to be used to dewater sludge contaminated with blue-green algae it is fitted with special shafts for the algae and special flocculants.
Mapal’s aeration system can be easily installed in any biological reactor and it is an ideal cost effective solution for municipal wastewater treatment plants due to its excellent ROI. The technology eliminates the need to deliver electrical power to the floating unit and enables to easily adjust the power according to conditions. The units automatically adjust themselves to the water depth resolving the leveling problem.
The company provides 1. Water and Wastewater consulting services 2. Monitoring system: Usage of horizontal motion of our system across Aeration Basin to programmable monitor - Dissolved Oxygen % Temperature Optional: Ammonia and more - in order to better control air inlets.
This technology has been identified by KOTEC(Korea Technology Finance Corporation) for WIPO GREEN's project in waste water treatment sector. Any request for contacting the technology provider will be facilitated by KOTEC. 1. Total Phosphorous treatment system - Realizes automation of the operation method. - Can be optimally operated by controlling operating factors according to raw water fraction. - Calculates the dosing quantity automatically according to total phosphorus concentration of raw water supplied and expects the effect to reduce the dosing costs.
Diffusaire offers dramatic energy technology savings for the aeration process of wastewater treatment plants (WWTPs). Its modular aeration units provide an innovative and cost effective way to operate a sewage treatment process efficiently and dramatically reducing operating costs by 25%. Diffusaire’s aeration technology will replace existing technology of fine bubbles or surface aerators with a novel method in providing fine bubble aeration at half the energy costs.
