Get Assistance with Dam Liners from the Experts

GDT Lining Systems have recently completed the construction of a Molasses Bladder Molasses generates CO2 and H2S when stored. Molasses often enters the storage hot and cools of emitting gas as it loses heat. If the gas is not removed from under the cover it will interfere with the roof drainage which may cause the gas flow under the cover to be blocked and large bubbles in the cover system to form.

A large central float with a gas collection pipe system on either side provides positive extraction of the gas by way or an inline industrial fan. Application of a small negative pressure under the cover has a big effect, pulling the cover down against the stored molasses and allowing water that is collected on top of the cover, from precipitation, to find its way to the perimeter drainage sump. Provide perimeter rather than central weights to the system.

GDT has been installing molasses storages for 30 years and has learned about the problems of gas produced.

GDT Lining has a mission to improve the industrial landscape by containing any harmful waste. We accept that waste is a biproduct of our industrial society. We aim to mitigate the downside to a level that is acceptable, by limiting the spread and effect of waste materials on everyday life.
