What certifications do you have?

We have obtained ISO 9001 and CE certifications. Our micro-nano bubble generators are regularly exported to various countries in Southeast Asia and the Americas for wastewater treatment projects.

What advantages does it have compared with traditional aeration equipment?

It generates ultra-fine micro-nano bubbles, which stay in water for a longer time and achieve higher oxygen transfer efficiency. It can oxidize pollutants, inhibit algae growth and improve overall water quality.

What is the warranty policy?

The warranty period is 1 year, excluding consumable parts. Please contact us for detailed warranty terms.

Key features

Tiny micro-nano bubbles realize full gas-liquid contact, effectively enhancing dissolved oxygen efficiency in water bodies.

The collapse of micro-nano bubbles generates hydroxyl free radicals, offering auxiliary oxidation performance for pollutant removal.

Low energy consumption together with flexible installation modes greatly reduces daily operation and maintenance costs.

Compatible with biochemical treatment, DAF and other water treatment processes, adaptable to a wide range of application scenarios.

Excellent suspension adsorption capacity helps separate fine impurities and improve water clarification effect.

Stable continuous operation with compact structure, occupying less space for on-site installation.

Capable of eliminating sludge adhesion and biofouling, lowering the frequency of system cleaning.

No need for extra chemical dosing under normal working conditions, achieving eco-friendly water treatment.

AI-Powered supplier vetting

SummaryThe supplier is a combined manufacturing company with one production line, documented outsourcing procedures, and valid manufacturing contracts with associated subcontractors. It provides broad customization and ODM services, but reported no new products during the past year and has no SDK availability. Quality systems include ISO9001:2015, ISO45001:2018, ISO14001, CE capability, documented inspection instructions, and recorded corrective-action and complaint-handling procedures. Service coverage is domestically oriented: it has inventory capability but no overseas warehouse, showroom, agents, branches, or reported overseas-service countries. Financial evidence is limited to a stated current ratio of 1 and historical operating information; monetary figures are omitted for privacy. The supplier states that it provides OEM services for well-known brands, but no specific customer names or cases are supplied.

Supplier typeThe supplier is identified as a combined company rather than an offshore company, and its offerings cover manufacturing, export trade, service, quality control, R&D, and sustainable development. This indicates a multi-function supplier structure, although the slice does not further define ownership or organizational composition.

CertificationsThe supplier reports ISO9001:2015, ISO45001:2018, and ISO14001 certifications, plus CE product certification capability. It also conducted regular fire drills during the past year, providing additional evidence of documented management practices.

After-Sales capabilityThe supplier has inventory capability, documented procedures and records for handling customer complaints and corrective/preventive actions, and a stated one-month average lead time in both peak and off-season periods. However, it has no overseas warehouse, showroom, agents, branches, or reported overseas-service countries, limiting international after-sales reach.

Customization capabilityBoth manufacturing and R&D information lists customization from samples, designs, minor and full customization, and flexible customization. The supplier also reports ODM availability, providing explicit evidence of broad customization support.

Product Q&A

Q:What applications can the micro-nano bubble generator be used for?

Widely used in black & odorous river restoration, landscape water purification, municipal and industrial wastewater treatment, soil remediation and cleaning projects.

Q:How to select the suitable model?

Model selection depends on circulating water flow, tank volume and water pollution level. You may share your working conditions, and we will provide professional selection proposal.

Q:Is the unit prone to blockage? What about daily maintenance?

Optimized internal structure effectively reduces clogging risk. A pre-filter is recommended if raw water contains lots of impurities. Regular simple flushing is sufficient for maintenance.

Q:Can the machine run continuously 24 hours?

Yes, the unit supports long-term 24-hour continuous stable operation under normal operating conditions.

Q:Can we customize specifications like material, connection size and working voltage?

Customization on material, interface size and voltage is supported to meet different overseas power standards.
