Import Catalytic Oxidation Tower — Buy in Bulk from Supplier in China

The catalytic oxidation tower supplied by Jiangsu Zeyu Environmental Engineering Co., Ltd. employs a surface catalyst together with chlorine dioxide as a strong oxidising agent, operating at atmospheric pressure and room temperature. The design enables direct oxidation of organic pollutants in wastewater, breaking double‑bond chromophores such as azo, nitro, sulfide, hydroxyl and imino groups. By interrupting these bonds the process achieves de‑colourisation and raises the biodegradability of the effluent, improving BOD and COD ratios. The tower therefore acts as a bridge between conventional physical pretreatment and subsequent biochemical treatment for high‑concentration, high‑toxicity, high‑salinity streams.

The catalyst is a rare‑class material impregnated onto activated carbon carriers that undergo multiple impregnation and heat‑treatment steps, providing a high surface area for reaction. Typical commercial towers are fabricated from stainless‑steel 316L to resist corrosion, with heights ranging from 5 to 10 m and diameters of 0.5 to 1.5 m. Standard catalyst loading is about 0.5‑2 kg per cubic metre of tower volume, and a typical flow rate lies between 1 and 5 m³ h⁻¹. Expected pressure drop across the packed bed is below 0.5 bar and the operating temperature is usually kept between 20 °C and 30 °C.

Industrial water‑treatment plants, municipal wastewater facilities and mining operations with saline effluents commonly source such towers to meet discharge standards. Buyers look for equipment that can reliably achieve COD removal efficiencies of over 80 % while maintaining low energy consumption. Jiangsu Zeyu lists the tower as a turnkey solution but does not disclose minimum order quantities, pricing or lead times; interested importers should contact the supplier directly to confirm those trade details.

Jiangsu Zeyu Environmental Engineering Co., Ltd. is located in the Maqiao Hi‑Tech Industrial Area, Jingjiang, Jiangsu Province, China. The listing shows a harbour‑level trust tier, but the response rate is recorded as 0 % and no average response time is provided, indicating that the supplier has not yet engaged through the platform’s messaging system.

The company advertises the catalytic oxidation tower as a specialised wastewater treatment solution that combines chemical oxidation with subsequent biological processes. No additional corporate history, employee numbers or client references are supplied, so buyers should request verification documents and recent project case studies directly from the supplier.
