Industrial Chemical Dosing Systems Company

Product Overview

- QILEE Chemical Dosing System is an industrial dosing solution designed to optimize external carbon source supply for denitrification in wastewater treatment (especially municipal sewage anoxic tanks and denitrification filters).

- The product is certified to multiple international standards, engineered for high performance and long service life.

- It is provided as part of QILEE’s modular, containerized, plug-and-play water treatment portfolio backed by ~20 years of process design experience and deployment in 40+ countries.

Product Features

- Integrated instrumentation and control: online flow meter on the organic inlet, feedforward and feedback NO3–N online sensors, control unit, and dosing flow meter.

- Variable-frequency dosing pump for precise, responsive chemical feed.

- Automated feedforward + feedback control strategy that uses NO3 as the control variable to adjust carbon dosing in real time.

- Built with quality materials and continuous QA in production; eco-friendly raw materials and compliance with industry standards.

Product Value

- Stabilizes total nitrogen (TN) removal and helps meet strict effluent standards by ensuring adequate and timely carbon supply for denitrification.

- Reduces chemical consumption by avoiding over-dosing during fluctuations in flow/quality, lowering operating costs.

- Lowers operator workload and operational intensity through automated, real-time control.

- Rapid deployment and modular design shorten commissioning time for treatment upgrades or new installations.

Product Advantages

- Proven high performance and durability demonstrated by international certifications and long-term use.

- Precise, adaptive control (feedforward + feedback) that compensates for flow and load variations and system delays.

- High build quality: good materials, smooth construction, and adherence to latest manufacturing standards and technologies.

- Company strengths: extensive process expertise, global deployment experience, commitment to eco-friendly materials and social responsibility.

Application Scenarios

- Municipal wastewater treatment plants requiring external carbon dosing for anoxic tanks, denitrification filters, or to meet tightened TN discharge limits.

- Industrial wastewater treatment, water reuse, and factory upgrades where controlled carbon dosing improves biological nitrogen removal.

- Modular/containerized water treatment projects needing plug-and-play dosing modules as part of MBR, UF, NF/RO, TMBR or membrane-integrated systems.

- Facilities seeking to reduce chemical costs, improve compliance stability, and minimize manual intervention in dosing operations.
