Does it produce lots of sludge? Is frequent sludge transportation needed?

Built-in sludge reflux system produces moderate sludge with long transportation interval to cut disposal cost.

Is later maintenance troublesome? Are spare parts expensive?

No high-cost consumables like membranes. Main spare parts are blowers and pumps, which are common and cheap to replace.

Can the treated water be reused?

Optional UV or chlorine dioxide disinfection unit. The treated clean water can be reused for green irrigation and ground washing.

How long does installation and commissioning take?

Pre-assembled in factory. Only pipeline and electrical connection on site, commissioning completed within 3-7 days.

How long is the warranty period?

One-year warranty for the whole machine; vulnerable parts such as blowers and pumps follow the manufacturer's warranty standard.

AI-Powered supplier vetting

SummaryThe supplier specializes in water treatment technology and equipment, offering solutions for water-quality and industrial applications. It reports ISO9001 certification, OEM and ODM services, flexible customization, four R&D engineers, two patents, an available SDK, and recent new-product development. Documented procedures exist for supplier assessment, corrective and preventive actions, customer complaints, and R&D documentation. However, finished products are checked by packing staff, and the supplier reports no quality assurance, overseas showroom, overseas agents or branches, offline trade-show participation, or overseas-service coverage. Export experience is stated as one year. Financial information is insufficient for judging credibility.

Supplier typeThe company specializes in water treatment technology and equipment and provides solutions for water-quality issues and industrial applications. This supports classification as a specialized water-treatment technology and equipment supplier.

CertificationsThe supplier states that it is certified by authoritative ISO systems, and the company overview specifically identifies ISO9001 certification. The provided information supports certification holding, although no certificate number, scope, or validity period is given.

R&D capabilityThe supplier reports a national science and technology progress award, an available SDK, four R&D engineers, two patents, R&D audit documentation, recent new-product development, and stated investment in technological innovation. These are explicit indicators of innovation activity and supporting infrastructure.

Production capacityThe supplier reports one-month average lead times in both peak and off-season, written procedures and records for supplier-service assessment, and documented corrective-action and complaint procedures. However, finished products are checked by packing staff and the supplier explicitly reports no quality assurance, preventing a positive assessment of overall production capability.

Customization capabilityThe supplier offers customization from samples, designs, full customization, minor customization, and flexible customization. Its R&D engineers are responsible for flexible customization, and ODM service and recent product development are also reported, demonstrating broad customization support.

Client casesThe supplier explicitly reports providing OEM services for popular brands, which is evidence of at least one category of brand-customer engagement. No customer names, project details, quantities, or independently verifiable case studies are provided.

Product Q&A

Q:What pollutants can AO process remove? What effluent standard can it reach?

It can degrade COD and ammonia nitrogen with denitrification effect. With disinfection, effluent meets Grade B standard for domestic sewage discharge.

Q:Can the equipment be buried underground? How long is its service life?

Underground installation is available. Carbon steel anti-corrosion tank lasts over 10 years; 304 stainless steel tank is more durable.

Q:What are its advantages compared with MBR machine?

No membrane consumables and regular chemical cleaning required, lower operation cost; low energy consumption of blowers, easy maintenance.

Q:How automatic is the equipment? Does it need full-time staff?

Equipped with PLC automatic control for aeration, reflux and sludge discharge. Only daily inspection is needed, no full-time operator required.

Q:What kinds of wastewater is it suitable for?

Suitable for domestic sewage from residential communities, homestays, hotels, villages and small factories, ideal for small & medium flow projects.
