Integrated Chemical Processes Chemical Dosing System Wholesale - QILEE

Product Overview

- QILEE Integrated Chemical Processes chemical dosing system is a skid-mounted nutrient dosing solution for wastewater treatment, supplied in two core models (QL-NU-200 and QL-NU-500) to match different flow scales.

- QL-NU-200: urea 1–10 mg/L (as N), phosphates 0.5–3 mg/L (as P); recommended solution concentration 10–30%; suitable for 50–500 m³/d.

- QL-NU-500: urea 2–15 mg/L (as N), phosphates 0.8–5 mg/L (as P); recommended 10–30%; suitable for 500–2000 m³/d.

- Dosage ranges are adjustable by water quality, biological activity and discharge standards; customized models available.

Product Features

- Intelligent control with DO-based automatic dosing to adjust nutrient feed according to biological activity.

- Dual-pump redundant design (main + standby) with automatic switch-over within ~3 seconds; pump wetted parts made of corrosion-resistant materials (e.g., PVDF).

- Remote monitoring and control via MODBUS/PROFINET, real-time alarms for low liquid level or pump faults.

- Real-time data recording, historical reporting and export for traceability.

- Skid-mounted integration of pumps, solution tanks, mixers and control cabinet with intuitive HMI for easy operation.

Product Value

- Ensures stable and precise nutrient supply to maintain optimal C:N:P ratios, improving nitrogen and phosphorus removal efficiency and biological process stability.

- Reduces chemical waste and operating cost by high-precision dosing and automated control.

- Minimizes downtime and treatment disruption through pump redundancy and remote monitoring.

- Provides traceable dosing and operational records to support compliance and process optimization.

- Adapts to seasonal and influent variability, keeping treatment performance consistent year-round.

Product Advantages

- High dosing accuracy (±1%) using precision metering pumps and intelligent algorithms.

- Turnkey, compact skid design reduces on-site installation time and simplifies maintenance; modular components enable quick replacement.

- Wide chemical compatibility (e.g., urea, ammonium chloride, KH2PO4) and robust performance in typical plant environments (0–40°C, ≤90% non-condensing humidity).

- Cost-saving through optimized chemical use and extended equipment service life; built-in redundancy lowers operational risk.

- Scalable and customizable to match various treatment capacities and process requirements.

Application Scenarios

- Biological Nutrient Removal (BNR) plants for stable TN and TP removal.

- A/O and A²/O biological processes to target nutrient deficits in specific reaction zones (anoxic/aerobic).

- Industrial wastewater biological treatment for low-nutrient effluents (chemical, electronics, printing & dyeing, pharmaceuticals).

- Seasonal nutrient supplementation (rainy or low-temperature periods) to maintain microbial activity and treatment efficiency.

- Municipal wastewater plants with unbalanced influent nutrient ratios requiring precise nutrient augmentation to meet strict discharge standards.
