SINOKLE Innovative Process for High-Polymer Produced Water Treatment

Facing the long-standing industry challenge of treating high-polymer produced water from oilfields, SINOKLE has introduced a highly efficient treatment process built around CDOF (ozone advanced oxidation flotation) unit and CDFU (cyclonic dissolved air flotation) unit as the core. The process not only raises treatment efficiency markedly but also delivers consistently compliant water quality, providing reliable support for oilfield environmental protection.

Core process advantages

1. Efficient oxidative polymer degradation
   CDOF units use ozone advanced oxidation to rapidly cleave polymer chains, greatly reducing the difficulty of downstream treatment and cutting overall energy consumption.

2. Physical demulsification, less sludge
   High-efficiency dissolved air flotation replaces conventional gravity settling; micro-bubbles achieve physical demulsification, markedly reducing oily sludge and its disposal cost.

3. Compact flow, small footprint
   The overall design is simple and the equipment layout compact, with high treatment efficiency and short retention time, suiting the limited space available at oilfield sites.

4. Intelligent, stable and reliable operation
   The units are skid-mounted and automated, supporting unattended fully automatic operation; this reduces manual complexity while safeguarding long-term stability.

5. Strong shock resistance, consistently compliant effluent
   The process tolerates water quality fluctuations well and keeps effluent compliant even when influent conditions change.

Field application and value
The process has now been implemented successfully in several oilfield wastewater projects, delivering clear environmental and economic benefits. Its efficiency, stability and energy performance make it an important technical advance in high-polymer produced water treatment.

Driven by continuous innovation, SINOKLE is committed to providing more advanced and more economical solutions for oilfield environmental protection, helping the industry achieve green, sustainable development.
