Water (process, boiler, cooling, waste) engineering
Utilities
A site-specific water strategy had to reduce consumption, stabilise quality and increase supply reliability across several streams.
About the case
Context:
Process water, CIP, boiler feed, (closed) cooling systems and waste water each require their own treatment and monitoring. Objective: reduce the water and energy footprint, stabilise chemistry and ensure discharge quality.
Approach:
We drew up a water balance and defined reuse loops: RO pre-treatment for boiler feed; closed cooling with a conditioning plan; a retention buffer upstream of pre-treatment to dampen CIP peaks. Gravity transfers to storage limit pump risks in potential Ex areas; breather/overflow protection and hygienic piping were provided. Inline measurements (pH, conductivity, turbidity) feed alarm and bypass logic. PFDs/PFBs, P&IDs, tagging and specifications (quality requirements, test/acceptance criteria) support execution and audits.
Result:
Higher supply reliability and stable water quality with lower make-up demand thanks to condensate/flush water reuse. The retention buffer stabilises pre-treatment and improves discharge quality; maintenance and inspections become easier thanks to unambiguous documentation.
