The Avenue Coke Works • Processed coal to produce coke • Coke used as a smokeless fuel and in the steel-making industry • Wastes from the process left behind when the works closed in 1992
Contaminated water • Large ponds or lagoons containing oil-contaminated water • Rainwater run-off collected from working areas
Water treatment plant • Contaminated water is cleaned at the water treatment plant
Water treatment plant • Dirty water is collected • Oil is skimmed off from the surface • Sediments are allowed to settle out
Water treatment plant • Water pH is adjusted before it enters the biological treatment tank • Microbes digest contaminants in the water • Air is pumped in to help this process
Water treatment plant • Water is further filtered to remove any remaining contaminants • Large ponds contain clean water ready to be used around the site
