Food Industry Wastewater Treatment: Untreated Trade-waste is usually something to keep far away from as possible due to foul odour and more. We love it – ‘tradewaste’ is a unique resource that can be tapped into with advanced treatment technologies and turned into a crystal clear, safe product for reuse. Why accept rising trade-waste fees? Transform industrial wastewater into profit. Clean water and energy can be had from many varying wastewater types.
