SAFE-Tank® Double Wall Tank System

Ferrics, alums and polymers are commonly used to treat water and wastewater. There are several reasons why these substances require specialized storage:
By providing the right kind of storage for these chemicals, safety can be maintained – and the integrity of the product can be preserved.
Several of Poly Processing’s features can make your storage system work for handling ferrics, alums and polymers. An IMFO® system is ideal for sludge control and ease of cleaning, since the tank drains at its true bottom. Heat pads and insulation can help keep the chemicals at the optimal temperature, greatly reducing the chance of separation and settling.
A mixing system can also be installed to keep the chemicals from separating – and a scrubber can help reduce the effects on foliage if you’re venting outdoors.
As for handling elevated temperatures – this is where the strength of the XLPE tank comes in. The crosslinked construction of these tanks allows for greater expansion and contraction, while maintaining structural integrity, lessening your risk for tank failure.
