Power-free chlorination of drinking water mains: dosing stability, compliance and maintenance

1 hour ago

Power-free chlorination on drinking water networks is typically deployed on remote or resilience-critical sites where electricity is unavailable, unreliable, or excluded by design. The technical challenge is to maintain a stable disinfectant dose (most often sodium hypochlorite) across real hydraulic variations (flow, pressure, transients) while keeping the installed configuration compliant with potable-water requirements (materials in contact with water, certified accessories, auditability). This article details the main drivers of dosing stability, the most common compliance constraints (NSF/ANSI 61 and the EU drinking water framework), and the maintenance checkpoints that most directly impact repeatability and life-cycle cost.

Maintaining proportional chemical dosing accuracy on variable-flow water networks: hydraulic limits, pressure effects, and additive properties

The 07/03/2026

Variable-flow water networks (irrigation manifolds, livestock watering, building services, industrial wash lines, mobile CIP skids) expose proportional dosing systems to pressure and flow transients, evolving pressure losses and suction-side constraints. This technical guide explains why ratio control drifts in the field, how pressure, backpressure and refill dynamics affect water-driven proportional dosing pumps, and how additive properties (viscosity, outgassing, crystallization, compatibility) can reduce volumetric efficiency. It also provides engineering practices to stabilize dosing, verify concentration correctly, and separate true injection accuracy from process residual behavior.
