Major pet food manufacturer

Choose Neutralac® SLS45

Neutralac® SLS45 has been identified as a highly effective treatment of effluent in the food Industry. It is used in a wide range of applications from pet food and dairy producers to abattoirs and general food processing.

Proven as a highly effective alkali reagent it is safer and superior to other alkali reagents and offers significant cost savings against Caustic Soda. As an innovative product designed to address the main objectives of reducing trade effluent charges and to achieve compliance for sewer discharge, it has been successfully applied to treat many food processing wastes. A leading food manufacturer in the North of England produces a range of fried food products and needed to treat an acidic effluent stream that contained oils, starches and fats. Prior to discharge into the sea it needed to be pH neutral and comply with the Environment Agency’s wastewater directives.

Neutralac SLS45 provided a significant rate of flocculation which, combined with its high reactivity improved processing capacity. By replacing the commonly used magnesium hydroxide slurry, they experienced an immediate price advantage due to better handling, dosing and storage properties. It also reduced the effects on plant equipment common with magnesium hydroxide slurry.
In 2010 a pet food processor commenced a small scale pilot trial using Neutralac SLS45.

The company chose Neutralac® SLS45 as it had proved itself in improving the performance of contaminant removal in Dissolved Air Flotation (DAF) Systems. The effluent is treated with poly aluminium chloride as a flocullating agent which lowers the pH of the already slightly acidic effluent stream. pH is then raised back up by the controlled addition of Neutralac® SLS45. A final dose of polymer is used to create a strong and stable floc which is then removed to waste.

Lhoist is now delivering Neutralac SLS45 in bulk using 10 tonne tankers. Derek Thompson, Product Manager for Neutralac® SLS45 is pleased with the final result.

He said “Neutralac® SLS45 creates a stronger and more stable floc than caustic soda and has been highly effective in treating and removing animal fats, oil and grease. It is also more cost-effective than other alkali’s, less hazardous and we can offer our customers improved performance and compliance.”
