A north-east company has developed a process to remove potentially harmful chemical waste from manufacturing processes.
The new process, developed by Integrated Effluent Solutions (IES) of Spennymoor, CountyDurham, has been developed with the aid of a £74,000 research and development grant from regional development agency One North East.
The 18-month project cost a total of £140,000.
The chemical process uses hypersonic vibrations to separate the sulphate from the waste water.
