A renewable energy company recently faced with a challenge of protecting its concrete containment system from corrosion attack.
Liner installed in containment pit
Renovation on the facility included the elimination of the old acid remnants in the containment area, followed by soil remediation. However, the low-quality thin gauge coatings and materials will fail to serve the need to eliminate corrosion. Furthermore, the un-bonded, modified liner will facilitate providing resistance to the cracks experienced in concretes. However, alternative coatings are loosely bound to the concretes and can easily be removed if it comes in constant contact with water from the sumps, and other groundwater sourced from leaky hoses, pumps, or valves, contaminated with spilled acid.
The company approached Melvin Stein of Stein Industries. Following the initiation, a dual containment area was designed for each acid tank equipped with a tank pad and collection sump at one of its end. Witt liner’s complete piece was installed in every area including the sump area. This facilitated rapid installation even before the concrete completes the curing process. According to Stein, these flexible liners are most effective and rapid technique of lining concrete areas.
The pumps, tanks, and other equipment can be replaced in its original position, following the installation of liner. This flexible PVC liner requires less time for installation and operation compared to all the other fixtures. The energy company thus successfully incorporated Witt’s technology in its containment system that will contribute to reliable, durable and low maintenance service.
