QILEE Chemical Dosing Systems Company

Product Overview

1) Product overview

Product Features

QILEE Chemical Dosing Systems is a customizable, scenario-oriented dosing solution that integrates high‑precision dosing hardware, online detection and an intelligent PLC control layer in a closed-loop “detect → control → dose → feedback” architecture. It is designed to replace unstable manual dosing and meet strict water quality and regulatory requirements across municipal, commercial and leisure water systems.

Product Advantages

- Closed‑loop automated control with multi‑parameter online sensing (turbidity, residual chlorine, pH, ORP, flow) and PLC (Siemens/Schneider) logic.

Application Scenarios

- Frequency‑conversion diaphragm dosing pumps with pulsation dampers and electromagnetic flow meters; dosing accuracy up to ±0.5%.

- Corrosion‑resistant storage and piping options (PE, 316L SS, FRP) with level sensors, alarms and stirring for viscous agents.

- Supports common agents: coagulants (aluminum sulfate, PAC, PFS, PAM), disinfectants (sodium hypochlorite, chlorine dioxide, ozone supplement) and pH regulators (NaOH, HCl, H2SO4, NaHCO3).

- Touchscreen HMI, protocol support (MODBUS, TCP/IP), automatic/manual modes and expandability (1–6 dosing units).

- Built‑in safety features: leakage detection, alarm, compatible pipe materials and anti‑corrosion measures.

3) Product value

- Ensures regulatory compliance and stable finished‑water quality (precise turbidity removal, residual chlorine and pH control).

- Improves process reliability—increases water quality qualification rates by 20–30% versus manual dosing.

- Reduces labor and human error—enables 24/7 unattended operation and cuts labor intensity by over 90%.

- Lowers chemical waste through accurate dosing (±0.5%), protecting operating costs.

- Flexible customization lets operators match capacity, agent types and control logic to site needs, protecting capital investment and easing future expansions.

4) Product advantages

- High precision and stability: frequency‑conversion pumps plus closed‑loop feedback maintain consistent dosing under varying flow/quality conditions.

- Scenario‑oriented design: modular configurations for large municipal flows, compact pool systems or commercial buildings with different detection sets and dosing capacities.

- Robust, safe construction: materials and tanks matched to chemical properties, with alarms and anti‑corrosion choices for oxidizers and viscous agents.

- Strong integration and expandability: interfaces for existing water systems, remote communication protocols and ability to add dosing channels or additional agents.

- Comprehensive support: prescribed installation/maintenance routines, 1‑year system warranty and 24‑hour technical support with remote guidance.

5) Application scenarios

- Municipal water treatment plants: raw water pretreatment (coagulant dosing for turbidity removal) and finished water disinfection (residual chlorine control) to meet drinking water standards.

- Commercial buildings and complexes: pH adjustment to prevent corrosion, stable residual disinfectant control for public areas (restrooms, foodservice).

- Hotels: supply water pH and residual chlorine control for guest safety; integrated pool treatment (turbidity removal, disinfection, pH control).

- Swimming pools and leisure centers: targeted dosing strategies for circulation systems—coagulants for clarity, disinfectants for microbiological control, pH regulators and ORP linkage for disinfection efficiency and swimmer comfort.
