Biological leachate treatment and membrane bioreactor (MBR)

Treat your effluents with the power of nature, benefiting from the properties of bacteria and other micro-organisms to abate organic and nitrogenous contaminants from your effluents and industrial water on-site. Ovive, experts in biological treatment and membrane bioreactors, can help you manage your most complex effluent and reuse projects.

Biological leachate treatment by BRM: an environmentally-friendly solution

Biological treatment of leachates using the Membrane Bioreactor is an innovative, effective and environmentally-friendly method.
Leachates are effluents produced by the combined action of rain and the fermentation of waste in the landfill. Highly charged with organic pollutants, nitrogen, metals and salts, leachates represent an environmental hazard and must be collected and treated accordingly. This technique makes it possible to treat these complex, concentrated effluents using a high-performance, cost-effective process.

BRM is a leachate treatment process that combines an intensive treatment stage, separation by ultrafiltration membranes and a finishing treatment (activated carbon, nanofiltration, reverse osmosis….). The reactor houses micro-organisms that degrade organic and nitrogenous pollutants. Membrane filtration considerably increases the concentration of bacteria in the biological stage, thus limiting reaction volumes and the plant’s footprint. Filtration retains the active biomass and separates it from the purified water.
The BRM is an on-site treatment (not concentration) tool. Ammonia, present in the waste and highly toxic to natural environments, is transformed into non-polluting nitrogen gas. The organic load is converted by biological action into CO2.
BRM technology enables large volumes to be treated, with high efficiency in the biodegradation of organic and nitrogen compounds and the reduction of mineral pollutants.

Advantages and applications of BRM technology

Using the Ovive BRM for leachate treatment offers several advantages:

The Ovive process is highly modular, so it can be easily adapted to variations in quality and volume. Simply add or remove an ultrafiltration tank or membrane to follow the evolution of the effluent.
Ovive tanks and containers are mobile, making them ideal for campaign treatments, with the possibility of pooling one tool for several sites.
Intensive oxidation in the reactors enables total removal of dissolved H2S.
Specific finishing treatments (arsenic, manganese, AOX, PFAS, etc.) can be added, made more effective by upstream treatment.

BRM technology generates superior treated water quality, in compliance with environmental discharge standards.

What’s more, the Ovive BRM system is designed for ease of implementation and operation, offering a long-term solution for leachate treatment. Ovive designs and builds its plants with the operator in mind, anticipating future changes in quality and quantity.

Finally, BRM treatment generates less sludge for disposal than conventional treatment processes, thereby reducing the costs associated with sludge management.

The environmental benefits of BRM treatment

In addition to high treatment efficiency, the main advantage of the BRM system lies in its positive environmental impact. Indeed, by optimizing the decomposition of materials by micro-organisms and significantly reducing on-site pollutants, BRM technology contributes to environmental protection.

The leachates treated by BRM can be reused, thus limiting water withdrawal from natural environments. In this way, BRM treatment contributes to the circular economy by transforming waste into a resource.

BRM treatment prevents leachate pollution of soil and groundwater, thus helping to preserve biodiversity and ecosystem quality. This method is a coherent process in the current context of energy and ecological transition, insofar as leachate treatment promotes better biogas production in the waste mass.
