Gigantic 50ft high 'blowing out towers' left behind at a disused bromine facility on the Welsh coastline. Sea water would be sucked in, treated with chemicals and then the resulting bromine solution quite literally 'blown' out of the water using this high pressure system which would churn in 22,000 tonnes of water in order to produce just 1 tonne of bromine. Despite clean sea water returning at the end of the process, the site was plagued with well-publicised pollution issues linked to the surrounding area, and when the site was decommissioned around 15 years ago it took the best part of a year to decontaminate. Only the bulkiest parts, around a quarter of the original structures now survive whilst the site awaits a new purpose.
