About Jiangsu Zeyu Environmental Engineering Co., Ltd. - Water Filters, Water Treatment Plants Supplier in China

Based in China, Jiangsu Zeyu Environmental Engineering Co., Ltd. lists five active products in its catalogue. The company focuses on equipment for agriculture and water treatment, covering both water filtration and treatment plant technologies. Its product lineup includes a catalytic oxidation tower, a high‑rate anaerobic reactor, a high‑rate reducing membrane evaporator, a TJAT type chemical dosing system, and a JDAF jet air‑floatation device. Each item falls under the broader HS‑code chapters for environmental protection machinery, typically classified in chapter 84 (e.g., 8421‑8422).

The catalogue reflects a niche specialization in processes that remove contaminants from water and wastewater streams. The catalytic oxidation tower is used for advanced oxidation of organic pollutants, while the high‑rate anaerobic reactor targets rapid biochemical oxygen demand (BOD) reduction. The reducing membrane evaporator combines evaporation and reduction steps, the chemical dosing equipment provides precise reagent injection, and the jet air‑floatation unit separates suspended solids and oils. Together, these five items constitute the supplier’s current offering for buyers in the agriculture and water‑treatment sectors.

Product Range and Specialties of Jiangsu Zeyu Environmental Engineering Co., Ltd.

Jiangsu Zeyu’s five listed units span the core technologies used in modern water‑treatment plants. The catalytic oxidation tower is commonly built from stainless‑steel (AISI 304/316) and designed for flow rates of 10‑50 m³/h, achieving oxidation efficiencies above 90 % for volatile organic compounds. High‑rate anaerobic reactors are typically configured as up‑flow packed‑bed systems with hydraulic retention times of 4‑8 h, delivering COD removal of 80‑95 % under mesophilic conditions. Reducing membrane evaporators often employ PTFE or PVDF membranes, operating at evaporation rates of 5‑15 kg/h and achieving moisture contents below 5 % in the concentrate. The TJAT chemical dosing equipment is engineered for dosing accuracies of ±0.5 % across a range of 0.1‑100 L/h, suitable for reagents such as chlorine, alum or polymers. The JDAF jet air‑floatation device uses fine‑bubble diffusers to lift oil‑laden or particulate suspensions, with typical removal efficiencies of 85‑98 % for oil‑in‑water emulsions. Industry standards for these machines include IEC 60335 safety requirements and, where applicable, EN 12255 water‑treatment plant design criteria.

Trade and Export Information - Jiangsu Zeyu Environmental Engineering Co., Ltd.

China is a major exporter of water‑treatment equipment, with the majority of shipments destined for Southeast Asian, Middle Eastern and African markets where rapid urbanisation drives demand for municipal and industrial wastewater solutions. Products such as catalytic oxidation towers and anaerobic reactors are classified under HS Chapter 84 (e.g., 8421 for machinery for water treatment, 8422 for filtration or purification equipment). Buyers typically request compliance with ISO 9001 quality‑management systems and CE marking for equipment entering EU‑type markets. Export logistics often involve 20‑ft or 40‑ft containers packed on wooden pallets, with standard Incoterms such as CIF or FOB Shanghai. Regulatory checks may include pre‑shipment inspection under the China Inspection and Quarantine (CIQ) regime and verification of conformity certificates for pressure vessels or electrical components.

Sourcing from Jiangsu Zeyu Environmental Engineering Co., Ltd. - Buyer Guidance

When sourcing from Jiangsu Zeyu, buyers should request the latest performance test reports for each unit, including COD/BOD removal rates for the anaerobic reactor and oxidation efficiency for the catalytic tower. Verify that the supplier can provide CE Declaration of Conformity or ISO 9001 certification, even if not listed, as these are common prerequisites for water‑treatment hardware. Ask for material certificates confirming stainless‑steel grades or membrane specifications, and confirm that the jet air‑floatation device meets EN 12255‑2 separation efficiency standards. Typical minimum order quantities are one unit per equipment type, with lead times ranging from 4 to 8 weeks after receipt of a confirmed purchase order. Packaging is usually in crate‑style wooden pallets with moisture‑resistant liners, suitable for ocean freight.

What types of water‑treatment equipment does Jiangsu Zeyu list?

The catalogue includes a catalytic oxidation tower, a high‑rate anaerobic reactor, a high‑rate reducing membrane evaporator, a TJAT chemical dosing system and a JDAF jet air‑floatation device.

Which HS‑code chapters cover these products?

These machines fall under HS Chapter 84, specifically headings 8421 for water‑treatment machinery and 8422 for filtration and purification equipment.

What performance data should a buyer request?

Buyers should ask for oxidation efficiency (>90 %) for the catalytic tower, COD/BOD removal percentages (80‑95 %) for the anaerobic reactor, membrane evaporation rates, dosing accuracy (±0.5 %) for the chemical dosing unit, and oil‑in‑water removal efficiency (85‑98 %) for the jet air‑floatation device.

Are any certifications typically required for these machines?

International buyers commonly require ISO 9001 quality‑management certification and CE marking for safety and environmental compliance; material certificates for stainless‑steel or membrane types are also standard.

What are typical packaging and shipping methods?

Equipment is usually crated on wooden pallets, protected with moisture‑resistant liners, and shipped in 20‑ft or 40‑ft containers under CIF or FOB terms from Shanghai.

What is the usual lead time for an order?

Lead times are generally 4 to 8 weeks after order confirmation, depending on the specific unit and any customization requests.

How can a buyer verify the supplier’s compliance before ordering?

Request copies of ISO 9001 certificates, CE declarations, and third‑party test reports; confirm that the manufacturer complies with China’s CIQ inspection requirements for exported machinery.

Is there a minimum order quantity?

The standard minimum is one unit per equipment type, allowing buyers to purchase individual machines such as a single catalytic oxidation tower or a single jet air‑floatation device.
