Forbes has developed the Minibulk-Total, a range of storage and process tanks, designed for hazardous liquids, which has an integral close fitting safety bund. At present capacities in excess of 40m3 are available.
Whereas so called “double skin” tanks are not full bunded tanks in the eyes of the HSE and the Environmental Agency, the Minibulk-Total range is fully compliant.
The most vulnerable parts of any tank are the low level connections which can be mechanically damaged or leak through gasket degradation. The Minibulk-Total system has all connections through the roof or against the top knuckle of the vertical shell. Liquid is discharged from the tank via a patented siphon system or via a run dry pump capable of lifting the contents over the top knuckle into the outlet down pipe. Either system can be supplied as part of the tank package.
The tank is integrally mounted in a close fitting secondary safety tank which acts as a safety bund. There is liquid monitoring within the bund area to give warning of any leakage.
The tanks’s inlet and outlet down pipes have the option of incorporating double containment, while the fill line can have an automatic shut off to prevent overfilling of the tank. A simple warning system gives warnings of high and low levels.
