Fish processing water efficiency
Tips for reducing water and liquid waste costs in fish processing businesses.
In the fish processing industry, reducing water use and liquid waste is crucial. By following best practices, businesses can minimise their environmental impact and operational costs.
Key water efficiency measures for fish processors
There are many simple ways for businesses in the fish processing industry to reduce water use and liquid waste, known as effluent. These include the following:
Minimise excessive water use
Turn off water when not in use, control flow rates with regulators, and conduct regular maintenance to prevent leaks. You should also implement measures to lower water usage during processing as this will reduce effluent volumes and trade effluent charges.
Separate fish waste from water and contain spills
Promptly separate fish waste from water and contain waste to prevent it from entering drains. This will reduce effluent strength caused by fish waste in contact with water.
Spillage containment
Provide spillage trays and troughs in suitable areas to contain spills and minimise water wastage.
Optimise water use during spraying
Use high-pressure, low-volume spray heads, direct the spray onto the appropriate section of the process, and provide spray system controls to avoid overuse.
Inspection and maintenance
Regularly inspect for leaks and ensure proper connections of hoses and pipes to prevent water loss. Clear the pipe lines with low-pressure air or a pigging system before using water to reduce the quantity and strength of the effluent.
Alternative defrosting systems
Frozen products are often thawed by immersing them in water. Avoid using water for defrosting if you can, and consider alternative systems instead such as air blast thawing units.
By implementing these measures, businesses in the fish processing industry can achieve significant cost savings through reduced water consumption and lower trade effluent charges.
Additionally, businesses can benefit from improved environmental sustainability, which can enhance their reputation and appeal to environmentally conscious consumers.
