Expert Wastewater Treatment FRP Tank Repair

Yes. FRP can often be repaired when damage is properly assessed and compatible materials are used. AFTR repairs compromised corrosion barriers, structural laminate damage, nozzles, manways, ductwork, and chemical storage tanks. The repair approach depends on the stored chemical, operating temperature, laminate condition, and whether the issue is surface-level, structural, or related to internal corrosion migration.

AFTR begins with an on-site assessment and testing to understand the tank’s corrosion coat, structural laminate, interfaces, and service chemistry. If damage is localized or the shell remains recoverable, repair or relining can extend service life at far lower disruption than replacement. Replacement is considered when the vessel cannot safely support continued operation after remediation.

AFTR selects resin, veil, and laminate systems for the specific chemical, concentration, and temperature in service. Common wastewater applications include sodium hypochlorite, sodium hydroxide, ferric chloride, hydrochloric acid, and other caustic or acidic chemistries. Materials may include isophthalic and terephthalic polyester, vinylester, epoxy, Nexus, Harlar, carbon veil, and fiberglass reinforcements.

Yes. AFTR regularly schedules wastewater FRP tank repair around customer operations, including planned shutdowns, night shifts, weekends, and seasonal maintenance windows. Crews arrive with stocked repair materials and can heat or cool the tank and work area when ambient conditions are challenging, helping reduce delays and keep the outage window focused.

Yes. AFTR provides 24/7 emergency FRP tank repair for incidents such as forklift impact, dropped equipment, tipped tanks, sudden lining failure, or other urgent damage. Field crews are supported by stocked Service-Pack containers with resins, mats, veils, and repair equipment, enabling rapid mobilization, damage assessment, structural repair, lining restoration, and return-to-service inspection.

Inspection may include visual evaluation, ultrasonic testing, laser measurements, high-intensity backlight testing, Barcol hardness readings, and close examination of nozzles, floors, shells, and corrosion linings. These methods help identify spidering, disbondment, abrasion wear, emulsification, capillary migration, shell distortion, ultraviolet degradation, and hidden laminate issues before they become major failures.

Yes. Wastewater treatment work is not limited to tanks. AFTR repairs and relines FRP ductwork feeding scrubbers and neutralizers, restores damaged fiberglass components, and modifies related FRP process equipment. This approach helps plants keep existing corrosion-resistant infrastructure in service instead of replacing large assemblies that may have long lead times and high installation costs.

Relining duration depends on tank size, access, chemical service, damage severity, surface preparation, cure requirements, and inspection needs. AFTR plans the work around plant schedules and mobilizes with compatible materials to reduce downtime. For many facilities, targeted relining is significantly faster than removing an installed tank and waiting for a replacement vessel to be fabricated and installed.
