Our biological treatment facility is part of Sterling’s Dudley site in the UK.

The plant is fully bunded, sits in 4.4 acres of land and has 12,000 tonnes of tank capacity, including two biological reactors. The associated control building houses our testing laboratory, offices and operational control centre.

The facility is integrated into Dudley’s production system to allow for treatment of our own process waste-water and is also licensed as an independent waste treatment facility, allowing commercial waste to be processed on-site. Providing a sustainable alternative to incineration and other disposal techniques, the treatment plant minimises the environmental burden associated with the disposal of waste, as well as offering a cost-effective solution for our customers. Pre-acceptance and waste acceptance testing is conducted on all waste-water streams to determine suitability for treatment and to ensure that all regulatory compliance requirements associated with the operating licences are met.

The on-site testing laboratory is staffed by highly skilled analysts with over 30 years’ experience in the industry. Specialised respirometers give real-time data on biodegradability and toxicity, ensuring all accepted wastes will be fully treated.

We have an unrivalled turnaround time with tankers usually sampled, discharged and off-site within 1 hour. We also have pumped and un-pumped discharge points so tankers without an integral pump can be safely discharged.

The treatment plant can deal with up to 20 tonnes of chemical oxygen demand (COD) and 1,500 cubic metres of liquid effluent per day. Tankered waste (up to 30 tankers per day) and on-site generated waste are treated at the plant using the following option:

  • Water miscible solvents
  • Inks and dyes
  • Interceptor waste
  • Petroleum products in water
  • Shipping waste waters
  • Slurries up to 10% solids
  • Leachates
  • Run-off water
  • Contaminated fire water
  • Agricultural waste waters
  • Pharmaceutical manufacturing wastes
  • Water based paint wastes
  • Mining waste waters
  • Engineering/machining soluble oils
  • Organic chemical manufacturing waste
  • Drilling and civil waste water
