Invention:
This invention introduces an advanced energy-efficient membrane bioreactor-membrane distillation (MBR-MD) system designed to change wastewater treatment and reuse. By combining biological treatment with membrane distillation, this technology guarantees high-quality water reuse while significantly cutting energy use. Unlike conventional systems that rely on membrane bioreactors followed by reverse osmosis (MBR-RO), which require large amounts of electrical energy and create brine waste, this MBR-MD system eliminates brine waste and runs on much lower energy levels. It offers a sustainable solution for industries and communities looking for energy independence and water supply security.
Background:
The main problem this technology addresses is the inefficiency of current wastewater treatment systems, which use large amounts of energy and produce harmful waste streams, like brine, that need further disposal. Existing MBR-RO systems, while effective, are not environmentally sustainable due to their high energy needs and brine waste generation. The MBR-MD system is different because it not only uses less energy but also cuts out the production of brine, making it a more sustainable option for decentralized wastewater treatment and reuse. This represents a step forward for industries wanting to reduce their environmental impact while keeping efficient water reuse practices.
Applications:
- Wastewater treatment for municipal and industrial sectors
- Water reuse and recycling in water-scarce regions
- Decentralized wastewater treatment systems
- Treatment of high-salinity or nutrient-rich wastewater
- Advanced water treatment for indirect potable reuse (IPR)
Advantages:
- Energy-efficient
- No brine waste
- High-quality water
- Cost-effective
