Chlorine Dosing Systems
The most economic means to eliminate bacterial contamination in water and ensure consequent disinfection is Chlorine Dosing Systems. Water disinfection is ensured by dosing liquid Sodium Hypochlorite (NaClO) to the water via a dosage pump with suitable capacity and properties. In order to obtain sufficient disinfection in drinking and utility waters, a free chlorine content with a maximum of 0.5 mg/L (ppm) must be provided.
Different operating models may be preferred according to their intended use;
- On/Off Control Dosing : Dosing systems running on external power/via contactor output
- Proportional Control Dosing : Proportional dosing systems running in proportion to the signals received from a flow meter with pulse output
- Time Control Dosing : Dosing systems with time setting
- Residual Chlorine Control Dosing : Measurement and dosing systems that run according to a setting on the device and reading of free chlorine in water measured via a probe in mV or mg/L (ppm)
