Problem

Wastewater from the fish processing industry, such as blood water and filleting water, contains high levels of fat, proteins, and organic matter, which must be removed to meet strict discharge requirements. The variability in feed water parameters – depending on the type of fish, processing methods, and production volumes – makes it challenging to design a reliable treatment system that consistently achieves the required outlet quality without excessive chemical use or operational complexity.

​

Solution
BioAqua has extensive experience in designing customized treatment systems based on specific feed-water parameters and discharge standards, primarily utilizing dissolved air flotation (DAF) to effectively remove fat and proteins. Where needed, flocculants are applied to enhance flocculation, while ozone is used to ensure disinfection of the water. 
 

Result
The implemented systems deliver consistent high-quality effluent compliant with regulations, while minimizing energy consumption and chemical dosing. Overall, BioAqua’s expertise enables fish processors to optimize wastewater management, reduce environmental impact, and potentially value by-products for economic benefit.
