Chemical Dosing Systems Products Wholesale - QILEE

Product Overview

QILEE Chemical Dosing Systems are wholesale-ready dosing solutions made with high-quality raw materials and advanced manufacturing technology. They are designed to support biological denitrification by accurately adding external carbon sources (e.g., acetic acid or sodium acetate) to urban sewage and wastewater treatment processes, with international certifications and tested long service life.

Product Features

The system integrates online organic inlet flow meters, feedforward and feedback nitrate (NO3) online instruments, variable-frequency dosing pumps, dosing flow meters, and a control device. It uses NO3 as the control variable and combines feedforward and feedback control to respond to fluctuations in inflow and water quality. The design emphasizes precision dosing, automated adjustment, and real‑time monitoring.

Product Value

By stabilizing denitrification performance and reducing over‑dosing of carbon sources, the system helps wastewater plants meet tighter total nitrogen (TN) discharge standards while lowering chemical costs. Automated control reduces manual adjustments and operational workload, improving process reliability and compliance with regulatory limits.

Product Advantages

QILEE’s systems are manufactured to international testing standards and claim superior performance and durability compared with peers. Long-term experience and advanced production increase output and quality control, and the integrated feedforward/feedback control strategy minimizes delays and disturbances caused by fluctuating flow and water quality.

Application Scenarios

Primarily suited for municipal wastewater and urban sewage treatment plants, especially in denitrification sections such as anoxic tanks and denitrification filters. Ideal where external carbon dosing is required to meet stringent TN limits or where inflow and water‑quality fluctuations necessitate automated, responsive carbon source control.
