How We Treat Over 100 Million Gallons Annually
Crystal Clean’s wastewater treatment facilities specialize in non-hazardous liquid wastewater and solid waste streams across multiple EPA subcategories. Our treatment process removes oils, heavy metals, organics, and other contaminants, producing effluent that meets standards for discharge to publicly owned treatment works.
Crystal Clean operates several state-of-the-art wastewater treatment facilities throughout North America to ensure cost-effective, environmentally sound disposal and treatment of wastewaters. Wastewaters are processed through our treatment system to remove oils, solids, and other contaminants, leaving clean water for discharge. The clean water is discharged to a publicly owned treatment works (POTW) to be further treated and discharged. Separated oils are sent to Crystal Clean’s used oil re-refinery and consolidated, stabilized solids are sent to a properly permitted, secure landfill for disposal. Our state-of-the-art facilities are permitted to treat multiple categories of waste.
Treatment Options Include:
- EPA Subcategory A – Metals
- EPA Subcategory B – Used Oils
- EPA Subcategory C – Organics
- EPA Subcategory D – Mixed
- Non-RCRA Liquids and Semisolids
- Non-Hazardous Solidification
- Oily Waters Treatment
- Petroleum Recycling
Collection
Professional Crystal Clean representatives collect wastewaters from generators which are then transported to a regional wastewater treatment facility.
Coagulation
The wastewater is sent through an oil/water separator and a coagulation agent is introduced, causing contaminates such as oils, heavy metals, and low-level organics to gather and settle at the bottom of the wastewater tank.
Precipitation
The gathered contaminates are transformed into a solid state using a solidification or chemical binding agent and then removed from the wastewater.
Adjustments
The wastewater is tested and treated to adjust it to a neutral pH level so that it is safe for the environment and for consumption.
Discharge
The treated water is sent to a POTW (publicly owned treatment works), where it goes through additional treatment and is then discharged into public waterways.
Relevant Services
These services generate waste streams that can be treated at Crystal Clean’s wastewater treatment facility.
