Paints and coatings require innovative wastewater solutions that meet increasing environmental regulations, minimize waste, and reduce operating costs. ACS has developed customizable programs for recycling and/or treating paints and coatings process water. ACS designs and installs wastewater systems that accommodate:

  • pH Control Systems
  • Biological Oxygen Demand Reduction
  • Chemical Oxygen Demand Reduction
  • Heavy Metal Removal
  • Total Suspended Solids Removal
  • Chromium Reduction
  • Total Dissolved Solids Management

Our comprehensive services include Initial Analysis & Recommendations, Compliance Testing, Wastewater Consulting, New Product Development, and Sludge Integrity Consultation.

• State-of-the-art automation programs integrate customer-specified options

Sludge Dewatering

• Sludge conditioning treats residual solids in preparation for dewatering processes.
• ACS provides several dewatering options for sludge recycling, processing or elimination.
• Our coagulants and polymers work with your filter press, dryers, and thickeners to remove water and improve cake dryness and production
• Dewatering reduces costs for disposal and improves operations efficiency


We offer a comprehensive line of scientifically formulated products for paints and coatings, including Acids/Alkalis, Coagulants, Defoamers, Deodorizers, Filter Aids, and Polymers.

The process water from paints and coatings is discharged (to the environment or municipal treatment plant) or recycled. ACS can provide customized neutralization reagents and equipment that adjust the pH down to acceptable limits for any end application.


Specific coagulants are employed to remove particulates, both soluble and insoluble. ACS can recommend specialized chemical blends that effectively remove solids and minimize sludge production.


Unwanted foaming can be problematic in paints and coatings applications. ACS provides careful control measures to minimize or eliminate the impact of foaming.


Our highly effective deodorizers are scientifically formulated to effectively neutralize odors in paints and coatings applications.

Filter Aids

Filter aids include powder-based flocculants that help remove organics from effluent wastewater streams. Some of the filter aids we offer include: Bentonite Clay, Diatomaceous Earth, and Calcium Hydroxide Blend.


Polymers are used to capture and conglomerate precipitated solids so that the solids may be effectively removed from the wastewater. ACS carries a broad range of differing density and molecular weight polymers that can be made-up on site or shipped ready to feed.


It takes reliable, high-performance equipment to exceed the exacting requirements of paints and coatings applications. ACS delivers with Full Batch Treatment Systems, Full Continuous Treatment Systems, Clarifiers and Clarifier Equipment, Filter Presses and Filter Press Equipment, Reuse and Recycling Systems, pH Control Systems, Accessories and Replacement Parts.

Batch Treatment Systems

Batch Treatment Systems utilize a sequential series of chemical processes that handle waste streams containing floating and settling waste product.
• Can process any chemically treatable wastewater
• Can handle 50 gallons to 10,000 gallons per batch
• Completely automated, requiring no operator other than for periodic system maintenance

Continuous Flow Systems

These multi-stage chemical reaction systems are designed to handle complex treatment issues requiring multiple stages and processes.
• Treats and removes contaminants to desired discharge levels
• Treats flow rates from 10 GPM to 3,000 GPM


Clarifiers consolidate contaminants and concentrates into a thick sludge, reducing the volume required for filter press.
• ACS combines clarifiers with appropriate components and chemicals to ensure efficient system operation and regulatory compliance

Filter Press & Filter Press Equipment

This highly automated equipment provides sludge dewatering capabilities by compressing slurry generated through normal precipitation and sedimentation.
• ACS chemists identify and maintain the proper mix of coagulants, filter press aids and chemicals to optimize system performance
• Only requires staff to start batches, clear filter cakes, and perform routine maintenance

Reuse/Recycling Systems

These systems may employ ultra-filtration, nano-filtration or reverse osmosis to further improve water quality for recycling within a facility.
• Cost reduction realized through recovery of high quality water for reuse
• Consumption of chemicals in cooling towers, boilers or other processes may be reduced

pH Control Systems

• pH Adjustment Systems maintain the pH of process water or wastewater for discharge to a sanitary sewer.
• pH Neutralization Systems adjust the pH of highly concentrated acidic or caustic solutions. After neutralization, the solutions are ready for use in specific manufacturing processes, or for discharge to sanitary sewer.

Accessories and Replacement Parts

ACS maintains an on-demand inventory of accessories and replacement parts to keep systems operating at peak efficiencies with minimal downtime.
• Distributor for major equipment manufacturers such as Den Hartog, Versamatic Hydranautics, Codeline and Weber Industries.
• Remote monitoring is available via building management programs
