Paint & Coatings Wastewater Treatment
Paint, pigment, and resin-laden wastewater is one of the more complex compliance challenges in industrial manufacturing. Pigments, heavy metals, emulsified oils, suspended solids, and chemical additives can all appear in the same waste stream, and their concentrations shift with every batch, product change, or equipment washdown cycle.
That's why ALAR manufactures paint and coatings wastewater treatment systems designed around that variability. Whether your facility runs continuous production or batch operations, our equipment is engineered to match your actual flow conditions, not an assumed average.
Connect with ALAR to evaluate your wastewater stream and receive expert guidance on the right treatment approach.
Compliance Solutions
What Makes Paint Wastewater Treatment So Difficult?
Regulatory pretreatment programs require industrial users to control what enters the municipal sewer system. For paint and coatings facilities, the regulated pollutants typically include copper and other metals, total suspended solids (TSS), oil and grease (FOG), and pH. Failure to meet discharge limits can result in permit violations, surcharges, or loss of discharge authorization.
The challenge is that paint and coatings wastewater does not behave consistently. Pigment loading, resin chemistry, and wash volumes fluctuate by product run.
A treatment system that handles one formulation well may underperform when production shifts. That is why ALAR conducts pilot and bench testing before recommending a system configuration, so compliance is grounded in data from your actual wastewater stream.
Paint & Coatings Operations We Work With
ALAR serves a wide range of paint and coatings operations, including:
- Water-Based Latex Paint and Coating Wastewater Pretreatment and Disposal Operations
- Industrial Spray-Booth and E-Coat Process Wastewater Operations
- Dissolved Air Floatation (DAF) and Clarifier Sludge Dewatering Operations
- Adhesives and Glue Manufacturing and Process Wastewater Operations
- Dispersions Manufacturing Process Wastewater Operations
- Powder Coating Manufacturers and Industrial User Wastewater Operations
- Stucco, Elastomers, and Primer Manufacturing Process Wastewater Operations
...along with discharges from many other operations associated with industrial water-based paint and coating operations. Each of these operations generates wastewater with its own characteristics, and ALAR's team has worked across all of them.
ALAR's Approach to Paint & Coatings Wastewater Treatment
ALAR is a direct manufacturer of chemical pretreatment and mechanical dewatering equipment, which means our engineering team works with you from evaluation through installation, without a distributor in between. Our systems can be configured as complete turnkey installations or as retrofits to existing infrastructure.
We offer:
- Continuous flow and batch chemical pretreatment
- Liquid-solids separation, including dissolved air flotation (DAF)
- Sludge dewatering with filter presses and the Auto-Vac rotary vacuum drum filter
- pH neutralization and metals precipitation
- Auxiliary equipment, including pumps, tanks, and controls
No two paint and coatings waste streams are alike. ALAR brings the chemical knowledge, engineering depth, and testing capability to find the right configuration for yours.
ALAR manufactures industrial wastewater treatment equipment for worldwide distribution.
Industrial paint and coating wastewater is a moving target; no two waste streams are alike. ALAR understands the difference and uses its chemical, engineering and technological expertise to deliver results that work.
Responsible industrial wastewater management makes the difference between regulatory compliance and non-compliance. ALAR offers a variety of mechanical and chemical pretreatment systems that allow customers to make an educated decision.
