Produced Water Treatment is a critical upstream process that removes oil, solids, and dissolved contaminants from water separated during oil and gas production. The treated water is typically prepared for safe discharge, reinjection into the reservoir for pressure maintenance, or reuse within the facility. Treatment trains may include degassing, hydrocyclones, flotation units, filtration systems, and polishing stages to meet environmental and operational specifications. Reliable analytical and monitoring instrumentation is essential to ensure discharge compliance, protect injection systems, and maintain treatment efficiency. Typical monitoring objectives include oil-in-water measurement, oxygen control, hydrocarbon contamination detection, solids monitoring, and flow verification. Our solutions support produced water treatment systems with robust online analyzers and instrumentation helping operators maintain regulatory compliance, protect assets, and optimize water management performance.
