Water and Waste water treatment
Industrial Waste
Treating water-based waste streams such as sewage, sludge, industrial waste and leachate is essential for the environment, but can be energy intensive and costly due to the large amounts of water trapped in the waste stream. Nthalpy’s waste water evaporation solution will greatly reduce the amount of energy required, thus reducing the overall cost of treatment. The system can also be used for the separation of heavy metals and oil from a waste water stream as required in some industrial processes. The additional benefit of reducing the volume of waste requiring final treatment also reduces transport costs for the client, further accelerating return on investment.
High temperature applications
Some effluent streams, commonplace in pharmaceutical and other life science processes, could benefit from being treated at high-temperature, (thermally treated), to inoculate the effluent before further processing or discharge to other sources. Nthalpy’s solution not only provides thermal treatment but is able to recover 98% of the thermal energy used, reducing total energy demand by over 85%.
Water recovery
Where the effluent constituency allows, Nthalpy is also able to recover up to 95% of the water content in the effluent stream back to the factory as pure distilled water for future use or for lower-cost disposal.
Nthalpy’s energy recovery technology enables thermal water treatment solutions with 1/40th of the running costs of conventional thermal solutions.
Clean water treatment
The use of thermal water treatment to generate pure and potable water from contaminated or saline sources has been available for many years. This very effective process of water treatment benefits from its simplicity,where the incoming water is boiled and condensed to form clean, distilled water, with very low impurities. This simple technique is however very energy intensive compared to reverse osmosis (RO) alternatives.
Nthalpy’s energy recovery solutions are designed to provide thermal water treatment with 1/40th of the running costs of conventional thermal solutions. Nthalpy solutions therefore compete favourably with RO on energy consumption, but also offer significant maintenance and cleaning cost benefits. Nthalpy is also targeting potable water production at a cost of $1 US dollar per 1000 litres, for populations not served by mains water. These simple, robust systems, sized up to 40m3/day, could then be aimed at water treatment for remote locations, the developing world, and secondary water treatment for industry. Systems coupled to small scale photovoltaic (PV) power generation can produce potable water completely free of any energy costs.
