Food and beverage manufacturing produces a complex wastewater effluent often difficult to treat due to its high salinity levels and heavy loading of contaminants.
Wastewater released from these industries are turbid, with high concentrations of total suspended solids (TSS), chemical oxygen demands (COD), biological oxygen demand (BOD), fats oils and grease (FOG), and nutrients such as nitrogen (including ammonia) and phosphate.
Other characteristics of food processing wastewater are large seasonal variation, large hourly variation in concentration and type of contaminants, often small and variable flows per day, and unbalanced concentrations of carbon, nitrogen and phosphorus, which complicates bioreactor treatment.
Treating wastewater from industries and farms has a dual potential benefit. Treated water can be recycled to help cut down industries’ fresh water use, and the waste load in wastewater can be converted to biogas and used to produce electricity.
Anaerobic digestion is a natural process that converts organic matter present in wastewater sludge into biogas for electricity, as well as significantly reducing the contaminant load in treated water.
The energy produced from the biogas can be fed back into the grid or used in other parts of the production process, which represents a real opportunity to reduce energy costs.

We take pride in providing high-quality products, technical credibility in the applications of water, process water, and wastewater treatment, dedicated delivery specialists and equipment, and proactive on-site technical service.
Almost 2 billion people do not have a decent toilet or access to basic and safely managed sanitation. In many cases, faeces and urine end up untreated in the environment, contaminating it and threatening people’s health.
This is why IER supports WaterAid programs, to facilitate access to safe water, sanitation and hygiene in the world’s poorest and most marginalised communities.
