MUNICIPAL WATER
Municipal water treatment involves a combination of filtration, disinfection, and temperature-sensitive conditioning. Across these stages, the fluids may contain suspended solids, biological material, and scaling agents that can foul conventional heat exchangers. Spiral Plate Heat Exchangers (SPHE) provide a robust solution by combining high thermal efficiency with excellent fouling resistance, even in harsh and variable water qualities.
The main challenges in this sector
The main challenges in this sector
Solids and biofouling risk
Surface water and wastewater streams often contain debris, biofilms, or chemical precipitates that threaten to clog traditional exchangers.
Strict hygiene and disinfection needs
Systems must maintain cleanable and sanitary conditions to meet potable water standards and protect public health.
Energy efficiency in preheating and recovery
Water heating and thermal recovery in treatment loops demand compact and energy-efficient solutions to reduce operational costs.
Variable flow rates and temperature profiles
Seasonal variations and fluctuating demand call for adaptable systems that maintain performance without excessive maintenance.
Our involvement in the sector
Spiral Plate Heat Exchangers from Nexson are used in critical points of municipal water treatment where fouling resistance, thermal stability, and easy cleaning are essential.
Spiral solutions for clean, efficient municipal water treatment
Wide-channel welded design
SPHE units handle solids-laden or chemically treated water streams with minimal clogging, maintaining performance over long periods.
Self-cleaning flow paths
Turbulent flow in a single-channel spiral path promotes continuous self-scouring, reducing biofilm build-up and extending service intervals.
Compact footprint with high thermal duty
Spiral technology enables efficient heat recovery in a space-saving format, ideal for compact installations or retrofits.
Low-maintenance, hygienic operation
Fully welded and gasket-free, SPHEs offer leak-free performance and are compatible with Clean-In-Place systems for sanitary use.
