Industrial Wastewater Challenges:

BOD/COD for Discharge: 

Managing Biochemical Oxygen Demand (BOD) and Chemical Oxygen Demand (COD) is critical in determining whether your wastewater can be safely discharged to a Publicly Owned Treatment Works (POTW) or local sewer system. High concentrations of BOD/COD can disrupt biological processes at treatment facilities, requiring precise control and reduction before discharge.

Heavy Metals Contamination: 

Industrial wastewater often contains heavy metals such as arsenic, barium, cadmium, chromium, mercury, and silver. POTW discharge permits limit these contaminants to prevent environmental harm and ensure regulatory compliance. Effective treatment processes are essential to reduce these concentrations to permissible levels.

pH Balance Management:

The pH level of your wastewater—whether acidic or basic—significantly affects its suitability for discharge or reuse. Maintaining the correct pH balance is vital to meet local discharge regulations and optimize subsequent treatment processes’ effectiveness, such as precipitation or neutralization.

Oil and Grease Removal:

Industrial wastewater often has fats, oils, grease (FOG), wet solids, and emulsified or dissolved oils. These contaminants must be effectively removed to prevent pipe blockages, equipment fouling, and environmental contamination. Advanced separation technologies can efficiently eliminate these substances, enabling compliance with discharge permits and the potential for water reuse.

Solids Reduction:

Discharge permits often regulate the levels of Total Dissolved Solids (TDS), Total Suspended Solids (TSS), and Total Solids (TS) in wastewater. High solids content complicates discharge compliance and hinders the reuse of treated water in industrial processes. Implementing robust filtration and sedimentation systems is crucial for meeting these requirements and optimizing water reuse strategies.

Regulated Chemicals Removal: 

Industrial processes can introduce many regulated chemicals into wastewater, including bromide, chloride, fluoride, sulfates, ammonia, and nitrogen compounds. These chemicals must be treated and removed to meet strict regulatory standards before wastewater can be safely discharged or reused. Using specialized treatment solutions tailored to your specific contaminants is essential for achieving compliance and minimizing environmental impact.

By addressing these critical challenges with PRAB’s advanced treatment technologies, you can make sure your industrial wastewater meets all regulatory requirements, protects the environment, and supports sustainable water management practices within your operation.

Each solution is custom-built to your process and specific chemistry challenges.
