INEOS ChlorVinyls’ wooden cooling towers were to be replaced but shutting down the cooling system would result in lost production, so the towers were to be replaced one at a time. In order to complete the on-line change 50m3/hr of cooling water, contaminated with demolition debris, flowing into the sump of the off-line tower had to be handled and treated.
Veolia Water Technologies’s solution was to provide an Mobile Water Services temporary plant consisting of pumps and two stages of filtration: coarse strainers followed by bag filters.
• Prevented discharge of contaminated water •Conserved water in cooling system •Cost saving around £30k
