WE TREAT WATER…


WITH ADVANCED TECHNOLOGY.


� Electrical charge coagulates suspended matter

� CleanWave removes suspended solids, petroleum hydrocarbons, and metals.

� 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


Economical Clean Safe

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 CO2 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
