QILEE Chemical Dosing Systems Chemical Dosing Systems Supply

Product Overview

- QILEE Chemical Dosing Systems are custom‑designed, factory‑manufactured systems for automated chemical dosing (principally sodium hypochlorite) and online residual‑chlorine control. They are built to industry reliability and performance standards and are offered in configurations to meet varied customer requirements and scales.

Product Features

- Integrated dosing unit with electromagnetic metering pump (2–20 L/h, pressure >0.6 MPa).

- Chemical storage tanks from 100–3000 L with lower‑level alarm/switch.

- Flow measurement (ultrasonic or open‑channel) and residual‑chlorine probe (0–10 ppm, 0.01 ppm accuracy) with industrial outputs (4–20 mA or 0–10 V).

- Control box provides automated/manual modes, real‑time display of flow and residual chlorine, composite control of dosing based on flow and residual value, and low‑level pump cutoff.

Product Value

- Ensures precise control of chlorine dosing to meet drinking‑water hygiene standards (adequate microbial inactivation and residual protection) while minimizing over‑dosing that can form harmful by‑products.

- Reduces operational risk and labor through automated monitoring and alarms, improves water safety and regulatory compliance, and delivers economic benefits from optimized chemical use.

Product Advantages

- High cost‑performance ratio and scalable configurations to suit small to large installations.

- Reliable automation with accurate sensors and standard industrial signal outputs for easy integration.

- Strong R&D and manufacturing backing, proven domestic and international demand, and focused technical support to tailor solutions to customer needs.

Application Scenarios

- Primary: chlorination and residual‑chlorine control in drinking‑water treatment plants and municipal distribution networks (including long branched pipelines and stagnation points).

- Also suitable for industrial process water disinfection, wastewater disinfection/polishing, water recycling systems, cooling systems and other settings requiring controlled chemical dosing and online residual monitoring.
