PWT
Produced Water as a Complex Separation Challenge
PWT™ is an integrated treatment solution for produced water generated during oil and gas extraction. Produced water contains a complex mix of dissolved salts, hydrocarbons, suspended solids, heavy metals, and treatment chemicals. PWT™ enables efficient removal of these contaminants to facilitate water reuse, reinjection, or safe discharge in compliance with regulatory requirements.
Integrated Separation & Contaminant Removal Train
Multi-stage treatment approach
combines physical, chemical, and advanced separation technologies based on water characteristics.
Oil & solids separation
removes free, dispersed, and emulsified oil along with suspended solids.
Dissolved contaminant reduction
targets dissolved organics, gases, and heavy metals.
System optimization
enhances performance of existing produced water and water injection systems.
Custom process design
technology selection based on well type, contamination profile, and reuse objective.
