Anaerobic Digestion and Biogas

Industry Solutions for Clean Water & Green Energy

FLI EnergySpecialist Anaerobic Wastewater Treatment
Our expertise lies in the biological treatment of medium and high-loaded organic wastewater by anaerobic processes. The treatment technologies use bacteria to digest the organic matter (Chemical Oxygen Demand or COD) in the wastewater and the process is called anaerobic because these bacteria don’t require oxygen.

Through anaerobic digestion, our technologies can remove up to 98% of organic pollution (COD) from the wastewater, making it suitable for discharge to surface waters. If necessary, for specific applications, the remaining pollution can be further treated by one of our complementing aerobic treatment systems.

Markets Served

Beer & Beverages
Anaerobic treatment has developed in recent years as the wastewater treatment technique of choice for breweries. Many soft drink and non carbonated beverages (tea, coffee- and milk-based drinks and fruit juices) bottling and canning plants have increasingly been choosing anaerobic treatment for their wastewater.

Food Processing & Canning Industry
The processing and canning of fruits, vegetables, meat, fish and seafood produces medium to high strength wastewater with ideal characteristics for anaerobic digestion. We can offer a unique variety of methane reactors, specifically designed to deal with the particular aspects of these effluents such as high levels of suspended solids, fats, oil and grease, proteins, ammonia, etc.

Snacks, Confectionary, Dairy
These industries produce effluents in a wide range of quantities and strengths. Most of them are suitable for anaerobic digestion. We can provide numerous successful references in these industries.

Agri & Agri Processing Industries
A large number of agri-industrial effluents are highly suitable for anaerobic digestion; amongst them are the beet sugar, starch, and palm oil processing industries and more recently the bio-diesel industry.

Fermentation Industry
This is a particular agri-processing industry, characterised by very high strength effluents (up to 150,000 mg/l COD and higher). The preferred feedstock is molasses, although all kinds of starch materials can be digested. This industry produces a variety of end products such as alcohol (bio-ethanol), baker’s yeast, fodder yeast, citric acid, monosodium glutamate, some pharmaceuticals, amino acids etc.

Pulp & Paper
A very successful application in this industry is the anaerobic treatment of the effluents from recycled paper factories.

Petrochemical Industries
Selected petrochemical industry effluents are also suitable for anaerobic digestion. For example PTA, PET, glycol and polyester factories have suitable effluents for which we can demonstrate positive practical experience.
