A new process referred to as bristle blasting has recently been endorsed by Belzona for surface preparation in certain situations where grit blasting is not possible. Although all major coating manufacturers recommend abrasive grit blasting prior to coating in order to maximize adhesion, it is not always feasible. In an effort to identify a better alternative, Belzona has conducted extensive testing on a new piece of equipment know as the MBX Bristle Blaster.

CuraFlo® offers two in-situ pipe renewal systems that improve water quality, increase flow and prevent corrosion-induced leaks in deteriorated metal and cement based pipes. Leaky pipes clogged with corrosion or minerals can be cleaned and lined to perform better than new pipes for significantly less cost than replacement and at only a fraction of the time and disruption. For small diameter pipes (½"– 4"), the company’s Engineered Flow Lining System™ blows the proprietary CuraPoxy® epoxy coating through pre-cleaned pipes.

Odor, corrosion control

While traditional bio and chemical odor control solutions pull air from the odor source, cleanse it and release the mostly clean exhaust into the air, Aerisa’s WaveFour™ odor abatement solutions take a very different approach to the problem by cleaning the air inside the facility, building, basin or pump station. The result: very low or no measurable hydrogen sulfide inside the buildings, providing a clean work environment for workers – and dramatically reduced corrosion in process control electronics and on the outside of equipment and pipe.

Caldwell Tanks has expanded its capabilities to provide tank asset preservation (TAP) for the life of water storage structures. The company can provide full-service ongoing maintenance contracts (TAP-ON) or periodic inspections and clean-outs (TAP-IN). Newly constructed tanks are excellent candidates for the TAP-ON program. The company also provides extended warranties (TAP-EX) on new Caldwell tanks that meet specific design criteria. For existing structures, the company will assess the water storage tank’s condition and design and implement a preservation program, including repainting and necessary safety, structural, and security repairs and improvements.

Columbian TecTank offers storage tanks coated with its proprietary Trico Bond EP™ epoxy coating, which is factory applied and thermally cured under environmentally controlled conditions. The coating will bend without breaking or tearing, ensuring low maintenance and reduced need for recoating down the road. The coatings are applied not in the field, but at the factory to ensure the most consistent application. A quality tank coating may have a higher up front cost, but lower life maintenance and recoating requirements.
