WMEC stands sentinel over multiple contaminant drums
Situated between the floodlights of Old Trafford Football Ground and the Trafford Park Container Depot is a small family business which cleans and refurbishes tanks and drums for the chemical industry, M&N Containers. Somewhere in the region of 800 items per week are pre-cleaned, washed out, steam cleaned, rinsed with clean water and dried ready for re-use by the customer. The main contaminants in the drums on arrival are salt, detergent, light oils and acid-based compounds.
The waste wash water runs into a 1,000-litre below-floor receptor tank. It is then pumped up to a 4,000-litre above ground holding tank and from there into a 2,000-litre Sentinel Treatment Plant. The plant removes the majority of the unwanted contaminants and adjusts the pH to meet discharge requirements. The company's water bill has been reduced from £2,000 to £800 per month - a payback period of two years.
