Containerized unit w/350 kVA generator High throughput process 2-20 bbl/min Scalable Multiple units work together to handle total flow in real time Handles wide variety of source waters (TDS range = 100 mg/l to 300,000 mg/l) CLEANWAVE SYSTEM WATER TREATMENT PROCESS Slide 5 5 2013 HALLIBURTON. ALL RIGHTS RESERVED. EconomicalCleanSafe Subtractive process reduces disposal costs Unique power management process keeps power costs low Extensive automation controls significantly reduce operational labor Non-speciality chemical process eliminates biotoxicity risks Non-selective process is broadly effective and largely independent of contaminant species, concentrations, and competing properties No CO 2 footprint from chemical manufacturing Automation controls tightly regulate treatment process Class 1, Div 2 and UL rated systems available Minimized waste residual handling Floating volts allows for consistent precision dosing OTHER ADVANTAGES Slide 6 6 2013 HALLIBURTON.
