Common problem answers for integrated sewage treatment equipment
📦 Integrated Sewage Treatment Equipment Q&A
Q1: What standard can your equipment's effluent reach? Can you guarantee passing the environmental assessment?
A: Our equipment adopts mature MBR or A/O biological contact oxidation processes. The effluent quality is stable and can typically meet the Class A standard of the "Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant" (GB 18918-2002). We support customized designs based on your local environmental assessment requirements (such as Class 1B or Surface Water Class IV), and we promise to provide water quality commissioning services to fully assist you in passing the environmental assessment.
Q2: I'm a client from a northern/cold region. Will the equipment freeze and break at minus 20-30 degrees in winter?
A: Please rest assured, we have specialized cold-resistant design solutions for harsh climates. The equipment uses thickened carbon steel with high-standard insulation, internal pipelines are equipped with automatic electric heat tracing systems, and the biochemical tank features anti-freeze circulation or insulation layers. This solution has been successfully verified in multiple northern projects, ensuring normal operation without freezing even in extreme low temperatures of -30°C.
Q3: We don't have professional environmental O&M staff. Is the later operation and maintenance of this equipment troublesome?
A: Not at all. Our equipment comes standard with a PLC intelligent fully automatic control system, enabling unattended operation; daily routine only requires regular inspections. Additionally, we will provide you with detailed operation manuals and free personnel training. If you encounter any technical issues later, our after-sales team provides 7x24 hour remote guidance or on-site support.
