A Japanese sewage treatment facility has invested in an anaerobic digestion system to create energy from waste. one of the major components of the system is a concentric digestion tank operating between 40 – 60°C with highly corrosive contents.

Corrocoat Japan was asked to recommend a coating system to protect the internal surfaces of the tank in both immersed and non-immersed service situations. Trials were arranged with test samples installed in situ in real life conditions and the results proved to be extremely positive. The results, backed by the excellent reputation of Corrocoat coatings, convinced the client that Corrocoat Japan was the perfect partner to protect the new digester tank and ensure the success of the client’s developments in the energy from waste sector.

The work entailed blast cleaning the internals of the stainless steel tank to SSPC 10 before applying Polyglass VEF to 850μm thickness, paying particular attention to achieve a professional finish at joints and on corners. A top coat of Polyglass Veilcoat was applied.

The performance of the finished coating in service conditions is reported to be excellent in line with the trial result and the client is very pleased with the protective coating work done.
