When dealing with the harsh and corrosive environments of water and wastewater treatment, there's a need for robust coatings and linings. Pioneering advancements in the sector offer solutions ranging from HDPE-based liners that boast long lifespans to innovative epoxy lining systems specifically tailored for caustic environments. With their unique chemical compositions and design, these coatings are not just protecting structures but are also playing a pivotal role in environmental preservation, ensuring longevity, and reducing maintenance.

PPG Protective & Marine Coatings RAVEN 405 
The RAVEN 405 wastewater treatment coating system from PPG Protective & Marine Coatings has high physical strength and broad chemical resistance to stand up to severe, caustic environments. This ultra-high-build epoxy lining system has Severe Wastewater Analysis Testing certification and passed the Pickle Jar Test, as its thick film can withstand high hydrogen sulfide gasses and other caustics, chemicals and acids found in a wastewater facility. Applications include concrete wastewater lining, clarifiers and digesters, tunnels and pipelines, tanks, secondary containment and manholes. Benefits include corrosion resistance, 100% solids, ultra-low VOC (0.52 g/L), adhesive strength and quick return-to-service. It can protect new concrete or help rehabilitate an existing structure. 888-977-4762; www.ppgpmc.com

AGRU America Sure-Grip

Sure-Grip liners from AGRU America are made of HDPE, HDPE-el, PP, PVDF or ECTFE, and serve as a long-term alternative to spray-applied concrete protection products. The liners prevent concrete corrosion and degradation, can substantially extend the lifetime of a structure, and by preventing exfiltration and infiltration, provide direct protection for the environment. The liners have anchoring systems that enable construction in areas of significant backpressure. Unlike spray-applied liners, which have to be reapplied regularly due to cracking or delamination, these liners are long-lasting, and are designed to avoid the residuals cost often associated with concrete spray-on liners, which require tank emptying and cleaning every few years for reapplication. 843-546-0600; www.agruamerica.com
