The Fine Bubble Disc Diffuser is a state-of-the-art aeration device designed to enhance the efficiency of wastewater treatment processes. This cutting-edge product is engineered to deliver a high oxygen transfer efficiency (OTE), with a Standard Oxygen Transfer Efficiency (SOTE) ranging from 22% to an impressive 59%. The Fine Bubble Disc Diffuser stands out in the market for its ability to significantly improve the dissolution of oxygen into wastewater, thereby facilitating the biological degradation of pollutants and enhancing the overall treatment process.

DUBHE Reverse Osmosis Membrane Elements are spiral-wound thin-film composite elements based on aromatic polyamide separation layers, designed for high-efficiency desalination and water purification. Covering extremely low-pressure, ultra-low-pressure, low-pressure, medium/high-pressure, anti-fouling, and seawater desalination series in standard 4040/8040 sizes, they deliver stable salt rejection up to 99.7% and high permeate flow with optimized hydrodynamic structure and strong fouling resistance. Suitable for municipal water, brackish water, seawater, industrial water, ultrapure water production, wastewater reclamation, and zero liquid discharge projects, they feature stable performance, low energy consumption, dry shipping for easy transport and storage, and reliable long-term operation under wide pH and temperature conditions.

The DHNS /DHBT series thickeners utilize either rotary drum thickening or filter belt gravity thickening processes to achieve high solid content treatment.It saves land, building and labor costs due to its simple structure, low flocculant requirement and fully automatic operation.
