Chemical Cleaning Waste Water
Typical Industrial Waste Water Streams
• Chemical Cleaning Operations
• Refractory Exchanges
• Sour Water Stripper Outages/Capacity Limitations
• Pipeline Chemical Fouling
• Storm Water Management
• De-Salter Mudwash & Cleaning Effluent
• Process Waters

Chemical Cleaning Waste Water
Internal Plant Systems Limited in Capabilities & Capacity
• Micro-Emulsions
• Surfactants
• Sour Water (Ammonia and H2S)
• Pipeline Chemicals
Limited Options
• Off Site Disposal Cost Prohibitive
• Internal Treatment Make-up > Discharge
Typical Waste Water Treatment Limitations

The Electrochemical Process
• Flexible application – electrolytic cell
can be customized to fit different
waste streams
• Used for the enhanced separation of
water mixtures

Chemical Cleaning Waste Water
Electrolytic Cell Strengths
• Can be used in separating phases typical in refinery waste streams
• Breaks out TPH, organics, suspended solids, and heavy metals

System Design – Customizable Technology
Em
• Adaptable Footprint
• Solids Management
• Emissions Management
• Highly Adaptable to Changing Water
Streams
• Multi-Stage Treatment Process to
Ensure Water Meets all Quality
Standards
• Staged Filtration Allows for Easy Capture
and Disposal of Solids Waste
• On Site Field Testing to Ensure Water
Quality

Filtration and Water Polishing
• Filtration can be necessary at
any point during the process
• Type of filtration will change
based upon discharge standards
• Filtration media will change
based on constituents of water

Based on these results we can
measure down to less than 1ppm
We can also correlate these results to a “foam
test” that can be done in the field

Summary
• Developed process to reliably field measure surfactant levels
• System proved capable of removing surfactants and other
contaminates from waste water
• Exceeded all refinery waste water standards
• All waste can be separated and captured
• Expanding capabilities to manage other refinery water challenges
