Integrated Chemical Processes Integrated Chemical Process Systems Wholesale - QILEE

Product Overview

1) Product overview

Product Features

- QILEE Integrated Chemical Process Systems provide automated nutrient dosing solutions for biological wastewater treatment.

Product Value

- Two core models: QL-NU-200 (for 50–500 m³/d) and QL-NU-500 (for 500–2000 m³/d).

Product Advantages

- Designed and manufactured with compliant processes and high-grade materials; supports customization for special scales or water quality.

Application Scenarios

2) Product features

- Precise dosing ranges: QL-NU-200: Urea 1–10 mg/L (as N), Phosphates 0.5–3 mg/L (as P); QL-NU-500: Urea 2–15 mg/L (as N), Phosphates 0.8–5 mg/L (as P). Recommended solution concentration 10–30%.

- Intelligent control system with DO-based automatic dosing logic, remote monitoring (MODBUS/PROFINET), alarms, and full data logging/tracing.

- Redundant dual-pump design (main + standby) with corrosion-resistant pump materials (e.g., PVDF) and

- Skid-mounted, modular layout integrating pumps, tanks, mixers and HMI for easy installation and maintenance.

- Compatible with common nutrient chemicals (urea, ammonium chloride, KH2PO4) and operable in 0–40°C, ≤90% non‑condensing humidity.

3) Product value

- Stabilizes biological nutrient balance (C:N:P) to improve removal of total nitrogen and phosphorus and help meet stringent effluent standards.

- Maintains continuous, year-round treatment performance via automatic adjustment for seasonal or influent variability.

- Reduces chemical waste and operating costs through high-accuracy dosing and intelligent control.

- Improves plant reliability and uptime with redundant components and remote diagnostics, simplifying compliance reporting via recorded historical data.

4) Product advantages

- High precision dosing (±1%) using metering pumps and intelligent algorithms to avoid under- or over-dosing.

- Robust reliability: compliant manufacturing, corrosion‑resistant components, and fast automatic pump switchover minimize downtime.

- Easy to operate and maintain: skid-mounted, intuitive HMI, modular components for quick replacement.

- Strong adaptability to different nutrient solutions, treatment scales, and harsh site conditions.

- Cost-effective sourcing and manufacturing from QILEE’s established supplier network, yielding competitive pricing.

5) Application scenarios

- Biological Nutrient Removal (BNR) systems needing precise N and P supplementation.

- A/O and A²/O processes to target nutrient deficiencies in anaerobic/anoxic/aerobic zones.

- Municipal wastewater plants with unbalanced influent nutrient ratios or strict effluent limits.

- Industrial wastewater biological treatment (chemical, electronics, printing/dyeing, pharmaceutical) with low nutrient content.

- Seasonal nutrient supplementation to stabilize performance during rainy seasons or low-temperature periods.
