Liners for Potassium Permanganate
Liners for Potassium Permanganate
(OP)
I have a 20,000 gallon concrete tank that holds Potassium Permanganate (KMnO4). The original liner/coating applied has disintegrated and we are looking to replace the liner. Apparently, KMnO4 has a high surface tension, and creeps (capilarry action) through any shrinkage cracks or imperfections in the concrete walls. We need a coating that can bridge these cracks and prevent the creeping action of the chemical. The tank is 10'wx 20'lx 14'h. It will hold 3-5% KMnO4.

An independent liner attached at a few critical spots (top of wall; at corner) using battens will be isolated from any cracks/movement of the tank. Plus the liner installers seem to be more quality conscious.

Tnemec Series 264 Elasto-Shield has been used in concrete water storage facilities with good results. I doubt it will; but, I'm not sure if the KMNO4 will react with the coating in an adverse manner. You want to make sure the coating you spec is compatible with your liquid.

Urethane, vinly and polyproplyne can be heat welded in place - allowing for total containment. Depending on tank shape and protruding piping,etc. - the liners can be preformed and simply dropped in place. In most cases, the concrete needs no underlayment or repair. Colorado Lining in Denver is good company - might try contacting them. Cheaper to use a liner then applying coatings - usually by 50%.
