In response to the increasingly stringent environmental requirements, we have currently developed the HBNA improved HBNB domestic sewage treatment device, which can assist shipowners in cultivating bacterial strains, and the effluent indicators stably meet the standards of IMO.MEPC.227(64) “2012 Discharge from Domestic Sewage Treatment Devices” The requirements of the Guidelines for the Implementation of Material Standards and Performance Tests and Articles 5.2.2 and 5.2.4 of GB3552-2018 “Water Pollutant Discharge Standards for Ships”.

The improved domestic sewage treatment device uses a biological flow bed process (MBBR for short) and a membrane biological reaction process (MBR for short) to combine oxidative degradation, microfiltration, ultrafiltration, physical disinfection and other processes to treat wastewater from ships (also known as It is suitable for domestic sewage in toilets, kitchens and bathrooms in offices, schools, hotels, residences and other factories and mining enterprises. It adopts modular design and split design to facilitate customers to transport and replace equipment.
