EHBR water body restoration aeration membrane technology
The ENHANCED HYBRID BIOFILM REACTOR (EHBR) technology is a new type of water body ecological restoration and treatment technology with enhanced coupling of micro-nano porous gas separation membranes and biofilms. While air passes through the micro-nano pores and high porosity EHBR membrane in the form of water vapor atomization to efficiently aerate and supply oxygen to the polluted water body, the original ecological microorganisms in the water body gather, attach, expand and reproduce on the surface of the EHBR membrane with excellent hydrophilicity and biofriendliness, and simultaneously adsorb and decompose organic matter and ammonia nitrogen and other pollutants in the water, thereby achieving the effect of ecological purification of the water body.
Ordered gradient micro-nano pore technology: nano-physicochemical oxygenation
By designing a high-porosity, outward-dense and inward-loose gradient ordered sponge-like pore structure, the resistance to filtration and mass transfer is reduced, achieving ultra-low pressure micro-nano bubble water vapor atomization aeration for efficient water oxygenation.
Plasma strong bonding technology: Ultra-high peel strength
By adopting surface plasma treatment technology and surface and interface crosslinking agent bonding synergistic technology, alloy membrane materials with ultra-high peel strength are obtained, significantly enhancing the peel performance of long-term aeration membrane materials and extending the service life of membrane products.
Asymmetric technology with internal repellency and external affinity: high strength and easy biofilm formation
The mechanical strength of the membrane is enhanced by adopting the hydrophobic braided tube lining alloy reinforcement technology. By adopting surface hydrophilic modification technology, bionic friendly surface interfaces are created to achieve easy biofilm formation, proliferation of microorganisms and efficient ecological restoration of sewage.
