Chemical Dosing Systems – Fully Automated, Skid-Mounted Chemical Feed Units for Water, Wastewater & Industrial Processes
A chemical dosing system is a complete integrated setup designed to prepare, store, and inject precise amounts of chemical additives into a process (usually water or wastewater treatment).
Our fully automatic chemical dosing systems integrate storage, preparation, metering, and control into a single, factory-tested skid—delivering precise, reliable, and safe chemical feed for applications ranging from municipal disinfection and RO antiscalant injection to boiler treatment and sludge dewatering. Trusted by EPCs, municipalities, and industrial plants in 20+ countries.
Why Choose an Integrated Chemical Dosing System?
* All-in-One Design: Combines chemical storage tank, mixer (if needed), dosing pumps, controls, piping, and safety accessories in one compact skid.
* Zero Manual Intervention: Automatic level control, solution preparation, aging (for polymers), and flow-proportional dosing
* Chemical-Specific Engineering: Material selection (PP, PVDF, SS316) matched to your chemical—acid, alkali, polymer, or disinfectant.
* Plug-and-Play Installation: Pre-wired and pre-piped—just connect power, water, and chemical lines. Commissioning in hours, not weeks.
* Smart Monitoring & Control: Standard PLC/HMI with optional remote access via 4G, Wi-Fi, or SCADA integration.
* Compliance Ready: CE certified, leak containment trays, ventilation (for fumes), and emergency shutdown.
