Background
Castle Dairies has been churning award winning butter since 1967 and supply supermarkets such as Asda, Aldi, Sainsbury’s, Waitrose, Marks & Spencer, Lidl and Morrisons. Their products include a range of salted, unsalted and spreadable butters produced from their modern facility in Caerphilly.
Wastewater produced on site was historically treated through a series of interceptor pits, which required periodic cleaning out via tanker. As well as a pH correction prior to sewer discharge.
The Overall Objective
The combination of chemical pre-treatment and Dissolved Air Floatation (DAF) processes delivers robust, low maintenance and efficient wastewater treatment solution for a high solid and FOG content reduction. Castle Dairies contacted SPS to meet their discharge consent of TSS, FOG and pH whilst eradicating pollution incidents and reducing their Mogden charges.
Solution
Siltbuster Process Solutions installed a chemical reaction tank and D10 DAF to treat wastewater before discharge ensuring the site is compliant with its trade effluent discharge permit.
