Company Integrated Solutions Working to Shape the Future
All subsidiary companies of the Aqua Group - Aqua Society GmbH and ENVA Systems GmbH - are independently operated companies.
Within their individual business fields they develop intelligent solutions for drinking water production, environmentally compatible waste water treatment and purification as well as for a consequent increase in energy efficiency by use of previously unused resources.
The companies co-operate closely with one another and coordinate business whenever appropriate. In this way, every single of them benefits from the know-how of the other ones and is able to offer integrated solutions to its customers.
All subsidiary companies are located in Herten, a centre of the European Rhine-Ruhr metropolitan area. Aqua Society Inc., a holding company, is - first of all - responsible for the strategic management and direction of the Aqua Group.
Energy from Waste Heat
The waste heat given off in industrial processes in the low-temperature range up to 100°C constitutes an energy potential in all industrialised countries that is left largely unused. Aqua Society has developed a new process for generating electric current from low-temperature heat, thus enabling the potential from this lost heat produced in many industrial processes to be made use of- In addition to its potential using waste heat sources, the process can also utilise heat from other sources for the generation of electricity, for instance from solar energy, geothermal heat, or technically conditioned waste heat flows from power stations and combined heat and power (CHP) plants. Through the specific utilisation of low-temperature heat for the generation of electricity, a major worldwide contribution could be made to reducing the consumption of fossil energy resources and cutting C02 emissions.
The main field of application of the EnergyMission process will be the utilisation of low-temperature heat in line with the performance characteristics of the expansion engine employed. Internal studies by Aqua Society into the efficiency of the process have been confirmed by independent studies.
Mode of Operation
The conversion of heat into mechanical and/or electrical energy using a cyclical process such as the ORC process, based on the following steps: Evaporation through heating, relaxation, condensation and heat eduction, return of the condensate.
The system can be applied, for instance, by utilising the waste heat from liquid media at temperatures above 70 °C:
- Any condensate in the food industry
- e.g. breweries, fruit juice plants, milk powder production
- Cooling water in block heat and power plants
- Process water in the chemicals industry
The generation of energy from waste heat is of benefit to all businesses that have unused thermal energy available or lose energy through the release of heat Target customers are therefore enterprises operating in the following sectors:
- Block heat and powerplant operators
- Aluminium smelters
- Solar thermic
