Hebei Huayu Environmental Engineering Co., Ltd’s disc air diffusers provide a versatile solution for oxygenation in water‑treatment processes. These disc‑type aerators generate fine to medium bubbles, enhancing gas‑liquid mass transfer and facilitating biological and chemical treatment stages.
Construction Details
The diffuser comprises a corrosion‑resistant backing plate (often of ductile iron with epoxy coating) and a replaceable membrane made of EPDM, silicone, or PTFE. Membranes feature a grid of laser‑cut perforations (0.5–1.2 mm), producing bubble diameters tailored to the application’s oxygen‑transfer requirements.
Performance Metrics
Operating at air pressures between 0.04 and 0.12 MPa, disc diffusers deliver 10–35 L/min of airflow per unit, achieving oxygen-transfer efficiencies up to 3.2 kg O₂/kWh in clean‑water tests. Low open‑area resistance minimizes blower load, and uniform radial bubble distribution ensures complete tank coverage.
Mounting and Configuration
Diffusers are mounted on rigid diffuser grids made of stainless steel or PE‑coated steel, with quick‑release clamp systems for membrane access. Floating diffuser arrangements are possible for tanks with changing liquid levels, using weighted hoses and buoyancy‑balanced anchors.
Maintenance Procedures
Membrane panels can be exchanged without draining the tank, and backing plates can be ultrasonic‑cleaned if fouling becomes severe. Hebei Huayu’s maintenance guidelines recommend periodic inspection of membrane elasticity and bubble pattern uniformity to optimize performance.
Applications
Disc air diffusers are ideal for aerobic digesters, oxidation ditches, tertiary aeration basins, and process‑water oxygenation in aquaculture or industrial cleaning lines. Their adaptability to various tank geometries makes them a go‑to solution for diverse water‑treatment scenarios.
