Waste & Wastewater Services for
Electronics & Semiconductor Manufacturing

Comprehensive Wastewater Solutions for Electronics & Semiconductor Manufacturers

Advanced Metals Removal & High-Purity Wastewater Treatment

Electronics and semiconductor processes generate wastewater with trace metals and ultra-low discharge limits. Valicor provides treatment solutions engineered for:

• Metals-bearing rinse waters (copper, nickel, chromium, lead, tin, silver, zinc)
• Etching and plating chemistry waste
• Lithography developer and photoresist residues
• Spent process solutions from PCB, semiconductor, and microelectronics lines
• Waste streams requiring precise pH neutralization and metals precipitation

Our centralized wastewater treatment (CWT) facilities support consistent, compliant treatment for complex, multi-step manufacturing operations.

Acid & Caustic Waste Treatment

Semiconductor and electronics facilities rely heavily on corrosive chemistries. Valicor accepts a wide range of acidic and alkaline wastewater requiring careful handling, dilution, or neutralization.

Typical waste streams include:

• HF, HNO₃, HCl, and H₂SO₄ acid solutions
• High-pH cleaners, alkaline etchants, and caustic developers
• Spent decontamination or surface prep chemistries
• Acid/alkali mixtures requiring controlled pH adjustment

This is a critical support service for fabs, PCB plants, and component manufacturers.

Bulk Liquid Disposal

Valicor manages a wide range of non-hazardous and certain hazardous liquid wastes generated during electronics and semiconductor production.

• Common waste types include:
• Off-spec or expired process chemicals
• Tank cleanout liquids and rinses
• Spent stripping and cleaning solutions
• Aqueous mixtures containing metals, solvents, or surfactants
• Solvent-contaminated water 

We ensure compliant, documented disposal that helps manufacturers maintain operational uptime.

Transportation & Logistics Services

Valicor provides reliable, nationwide logistics for semiconductor and electronics manufacturers requiring consistent, secure movement of liquid waste:

• Vacuum trucks for high-solids or slurry pickup
• Bulk tankers for high-volume wastewater
• Scheduled and dedicated route service
• Rapid-response and emergency pickup options
• Full tracking, manifests, and compliance documentation

This ensures higher uptime and reduces in-house waste handling risks for manufacturing teams.

CMP Slurry & High-Precision Solids Waste Management

Chemical Mechanical Planarization (CMP) generates highly specialized slurry waste streams containing abrasive solids and trace metals. Valicor provides safe, efficient handling and disposal of:

• Silica, alumina, and ceria-based CMP slurry
• High-solids wastewater and particulate-heavy streams
• Filtration byproducts and captured fines
• Rinse waters containing polishing agents and suspended solids

We ensure stable, compliant management of one of the most challenging waste categories in semiconductor fabrication.

Cooling Water, Glycol & Utility Waste Streams

High-tech manufacturing requires large-scale cooling and environmental control systems. Valicor supports safe and compliant treatment or disposal of:

• Glycol mixture waste from cooling loops
• Cooling tower blowdown
• Chiller water contaminated with metals or particulates
• Utility rinse waters and non-process liquid waste

This complements growing ESG requirements around reducing water consumption and preventing contamination.

Hazardous Wastewater & Liquid Waste Solutions

Many semiconductor and electronics processes create regulated or characteristic hazardous wastes. Valicor supports safe, compliant management of:

• Ignitable or solvent-containing wastewater
• RCRA-characteristic acidic or caustic liquids
• Metal-contaminated hazardous wastewaters
• Solvent/aqueous mixtures or residues
• Photoresist, developer, and lithography chemistry wastewaters

All handling is documented, tracked, and compliant with federal and state regulations.

Water Reuse & Sustainability Support

High-tech manufacturers are among the most water-intensive operations in the world. Valicor assists customers in meeting sustainability goals through:

• Waste volume reduction strategies
• Resource and water recovery opportunities
• Waste minimization through optimized consolidation
• Support for ESG reporting and environmental metrics

Our solutions reduce environmental impact while improving operational efficiency.
