The preferred solution for high-strength wastewaters resulting in crystal clear effluents.
Memthane® is an Anaerobic Membrane Bio-Reactor (AnMBR) which maximizes renewable energy production while producing superb quality effluent that can be reused or discharged directly to sewer.
The new leading-edge technology, developed by Veolia Water Technologies' subsidiary Biothane, delivers a unique, small footprint solution that offers an array of benefits, reducing disposal costs while generating valuable biogas.
Replacing fossil fuels by generating biogas from wastewater treatment.
ECONOMICAL AND EASY TO OPERATE
In addition to its performance advantages, Memthane® delivers a significant total operating costs reduction compared to conventional technologies, taking into account all elements, including membranes, chemicals, sludge disposal and overall energy savings. The simple, single, fully automated reactor system offers the possibility of remote control.
SUSTAINABLE AND PROFITABLE
Memthane® opens the door to treatment of high-strength and high-solid streams found in industries like distilleries, dairies, bio-ethanol producers, instant coffee plants, etc.
The suspended free effluent also facilitates easy recovery of nutrients for fertilizer production and water recycling to the plant.
The valuable methane-rich biogas produced can cover a significant part of the production plant's energy and heat demand, which can be as high as 100% in distilleries, for example.
Due to the favorable investment and operating with robustness, clients are increasingly choosing Memthane® as their preferred wastewater treatment solution.
Memthane® treats high-strength effluents previously considered untreatable.
Memthane®, the perfect solution for:
- High concentrated streams
> COD 15,000 ~ 250,000 ppm such as Dairies whey
- Ethanol Facilities
> Stillage type streams: Pot Ale, Spent Wash, Thin Stillage and Vinasse
- Fat Oil and Grease (FOG) containing streams
> Ice cream and Biodiesel
- Starch slurries
- High COD chemical applications
2 proven technologies:
- Anaerobic biological treatment + Membrane separation = 1 innovative solution
- Maximizes COD + TSS removal,
- Eliminates disposal costs
- Generates methane-rich biogas

Memthane® combines two proven technologies: Biothane's anaerobic biological wastewater treatment and Pentair's X-Flow ultrafiltration membrane separation process.
Anaerobic Biological Treatment
Anaerobic treatment is the proven and energy efficient method to convert industrial wastewater into biogas. Low energy requirements, a smaller reactor footprint, lower chemical usage and reduced sludge handling costs are among the technology's advantages.
Biogas produced through anaerobic treatment can make the plant energy neutral or even a renewable energy producer.
Membrane Separation (UF)
The ultrafiltration membrane unit provides a solution that is robust, reliable and flexible.
Memthane® minimizes the surplus sludge production by applying long sludge retention times. The membranes are placed outside the reactor, offering a simple and easily maintainable stand-alone system that is fully enclosed, preventing odor release.
