The Need The Solution Key Advantages Cost Benefits Treated Contaminants
The Need Industrial water and wastewater treatment activities require unique solutions that enable high levels of efficiency in water recycling, chemical purification and recovery, and waste minimization. Many industrial wastewater streams are complex mixtures of hazardous minerals and organic substances dissolved in water; as a result, their disposal to water bodies or publicly owned waste water treatment plants (POWWTPs) is restricted. Industries generating such wastewater streams must install dedicated onsite wastewater treatment plants to reduce the concentrations of hazardous contaminants to comply with discharge limit values.
The Solution The HMT™ (Hybrid Membrane Technology) system provides a full solution for the treatment of complex industrial water and wastewater streams. HMT™ is a membrane-based system – integrating BPT Nano-Pro™ or third-party membranes – specially designed for treating industrial wastewater containing hazardous organic matter, minerals and organic solvents. HMT™ aims to: • Recover from wastewater as much high-quality water as possible (80%-90%) for reuse in the factory • Produce low-volume streams of highly purified and concentrated minerals that can be either sold as valuable salt or easily disposed into evaporation ponds • Produce minimal-size streams of highly concentrated organic substances (less than 3% of wastewater volume) for final and economic destruction by oxidation or incineration
Key Advantages • Converts hazardous wastewater streams into purified recyclable water (up to 90%) • Recovers purified minerals for reuse • Handles all types of industrial wastewater • Installs upstream or downstream of biological wastewater treatment plant • Achieves lower total cost of ownership (TCO) than alternatives • Features simple installation and full automation
Cost Benefits Conventional wastewater treatment technologies, such as evaporation, wet air oxidation (WAO) or incineration, are extremely expensive for treating the whole wastewater stream. HMT™ leads to a dramatic reduction of overall treatment costs, since only a small residue requires treatment after usage of the system.

Many of the chemical substances listed above endanger the microbes that perform the biological degradation of wastewater; they can inhibit or even stop their biological activity and can interfere with the operation of biological wastewater treatment plants. Moreover, many substances that are present in the wastewater of the chemical and pharmaceutical industries are not biodegradable. As a result, the effluents contain too many organic contaminants and cannot be discharged to POWWTPs. Industries with typically difficult-to-treat wastewater include: • Pharmaceuticals • Herbicides • Pesticides • Biocides • Detergents • Cosmetics • Petrochemicals
