Warren Environmental – Epoxy Coating for Digester
One Coat. 75 Years.
About the Company:
Warren Environmental epoxy coatings are highly resistant to H2S and tolerant of very low pH. Their 100% solids epoxies protect pipes and entire wastewater systems to stop inflow and infiltration (I&I), while enhancing structural properties.
They specifically formulated epoxy blends to solve issues with corrosion, microbial attack, and sewer gases while extending the service life of your high-value assets for over 75 years. Their products will reduce your risks while minimizing operational disruptions.
About the Solution:
Warren’s epoxy coating system is a quick and effective rehabilitation method that adds valuable service life to anaerobic digester tanks with minimal impact on their operations.
Warren’s approved applicators use 301-14 epoxy to repair tank’s concrete surfaces. Before coating the walls, the team sandblasted and water blasted to remove loose concrete. Afterward, they spray applied 375-500 mils of Warren’s 301-14 epoxy to the concrete surfaces. Areas with exposed rebar required repair with Warren’s epoxy mastic before being coated.
Solution Strengths, Weaknesses and Critical Indicators
Anaerobic Digester Associated Technology:
NOTE: There are several technology types that are used as part of an integrated manure management system that includes an anaerobic digester and are not applicable to manure management in other cases. The impact of these technologies on the critical indicators are represented as those of an entire anaerobic digester system.
- Long usable life and can be run reliably
- Creates energy and generates environmental credits
- Requires proper preparation of the feedstock
- Requires other technologies for energy utilization
- Requires other technologies for digestate handling
- Proper feeding & system monitoring is required to avoid system downtime
- Proven technology for odor control, GHG reduction and pathogen reduction
Warren Environmental has recently been added to the solutions catalog, Newtrient will continue to work with them to further refine the cost and performance information, publishing it and updating the 9-Point score as information becomes available and as new commercial dairy installations come online.
