Industrial Water Treatment

Process Water Across Manufacturing and Heavy Industry

Industrial water treatment is the broad sector that covers every duty where the water itself is the process input or the regulated effluent: process water polishing for sensitive manufacturing, cooling tower blowdown for thermal duty, boiler feedwater preparation for steam generation, and groundwater remediation for legacy contamination at industrial sites. The contracted limits are set by the operator process specification on the inlet side and by the regional environmental permit on the discharge side. SorbiTech serves the sector with SorbiTech activated carbon and activated alumina, SorbiTech contactor skids, and SorbiTech EPC for the larger installations.

Recurring Duties

The high frequency duties served by SorbiTech across this sector include:

• Process water polishing for electronics, pharmaceutical, and food manufacturing, GAC 1240 for dissolved organic carbon and chlorine residuals
• Boiler feedwater dechlorination and dissolved organics removal
• Cooling tower blowdown oil and grease removal before discharge
• Groundwater remediation against historical industrial contaminants (BTEX, chlorinated solvents)
• Fluoride and arsenic removal from industrial supply water with AA-201 activated alumina
• PFAS removal from contaminated industrial sites

Regulatory Drivers and Permit Compliance

Industrial discharge consents vary by jurisdiction but share the same technical structure: total petroleum hydrocarbons below a regulated limit (typically 5 to 15 mg/L), suspended solids below 30 mg/L, biological oxygen demand and chemical oxygen demand limits per the receiving water classification, and increasing focus on the emerging contaminants list (PFAS, microplastics, pharmaceutical residue). The SorbiTech design team tracks the regulatory landscape in each jurisdiction and provides the design report that supports the operator permit submission.

Cooling Tower and Boiler Feedwater Duties

Cooling tower blowdown carries the cycle of concentration of the make up water plus the carry over of process leaks; a SorbiTech polishing stage of activated carbon followed by particulate filtration removes the regulated oil and the dissolved organic load before discharge. Boiler feedwater preparation runs upstream: dechlorination with GAC 1240 protects the downstream demineralisation resin from oxidative damage, and a dissolved organic carbon polishing stage extends the resin campaign life by 30 to 50 percent.

Groundwater Remediation and Industrial Legacy Sites

For industrial sites with legacy groundwater contamination, solvents from a closed plant, chlorinated hydrocarbons from a historical leak, or petroleum residue from an old fuel storage, SorbiTech delivers granular activated carbon contactor systems sized to the contaminant load and the abstraction rate. The SorbiTech skid is designed for relocation as the remediation plume moves, and SorbiTech handles the civil installation when the contractor scope includes wellfield works.

Service Contracts and Reactivation Programmes

For continuous operators in this sector, SorbiTech offers a carbon reactivation contract that replaces the spent GAC 1240 at a 7 to 12 percent makeup loss and returns the regenerated mass within four to six weeks. The avoided cost of new media plus the avoided disposal of spent media together lower the lifecycle cost of an industrial water filter by 40 to 60 percent compared with single use operation.

Integration with Effluent Treatment

Where the operator runs a complete effluent treatment train (e.g. a refinery, a petrochemical complex, a vehicle wash facility), the SorbiTech polishing stage sits at the outlet downstream of CPI separation and coalescing polishing. The complete train delivers one performance guarantee from inlet flange to outlet discharge, with single SorbiTech accountability across media, equipment, and EPC execution.
