fine bubble membrane disc diffuser for livestock wastewater
Product Overview This fine bubble disc diffuser is designed for submerged aeration in the biological treatment stage of livestock wastewater systems. Mounted on air distribution laterals near the basin floor, the membrane releases fine bubbles to supply oxygen for aerobic treatment. It can be specified for pig farm wastewater treatment projects after solids removal and appropriate pretreatment.
Key Features
  • Perforated membrane distributes fine bubbles across the active disc surface.
  • Modular arrangement supports new aeration tanks and suitable grid retrofits.
  • Disc holders and lateral piping can be laid out to suit basin dimensions and oxygen demand.
  • Accessible retaining components support membrane inspection and replacement when the basin is drained.
  • Material and connection selections can be matched to the wastewater and site conditions.
Structural Components A typical assembly comprises a precision-perforated flexible membrane, a supporting disc body, a retaining ring, a sealed air connection, and a holder fitted to the air lateral. A complete fixed-grid system may also include distribution headers, drop pipes, supports, anchors, and blower connections. Final materials and supplied components are confirmed for the project.
Working Principle Air from a blower travels through the header and laterals to each submerged disc. Under operating pressure, the membrane perforations open and release fine bubbles into the wastewater. The rising bubbles transfer oxygen to the liquid and contribute to tank circulation. Diffuser quantity and spacing must be designed around the required oxygen transfer and mixing conditions.
Technical Specifications
  • Diffuser type: Submerged fine bubble membrane disc
  • Membrane material: EPDM or another suitable option, subject to wastewater assessment
  • Disc size and airflow range: Available upon request
  • Connection and piping: According to project requirements
  • Grid layout and diffuser quantity: Designed according to basin geometry, loading, and treatment targets
  • Operating temperature and material compatibility: Confirmed for local climate and wastewater conditions
Applications Suitable for engineered aerobic treatment tanks serving commercial pig farms, livestock production sites, manure processing facilities, and agricultural wastewater projects. Application should follow an assessment of suspended solids, organic loading, cleaning chemicals, and the upstream treatment process. Screening and solids separation help reduce the risk of diffuser fouling.
Customization Options Disc diameter, membrane selection, connection type, lateral spacing, support arrangement, and the scope of the air distribution grid are customizable according to project requirements. For pig farm construction projects, the design can be coordinated with tank foundations, pipe penetrations, blower placement, and service access within the overall farm utility layout.
Installation & Maintenance Install the diffuser assemblies on correctly supported and level air laterals in accordance with the approved grid drawing. Check connections and air distribution before commissioning. During operation, monitor blower pressure and dissolved oxygen trends; inspect membranes for fouling, damage, or loss of elasticity during planned basin maintenance. Cleaning and replacement intervals depend on wastewater characteristics and operating conditions.
Product FAQ

Can the diffuser treat raw pig manure slurry directly?
It is intended for an engineered aeration stage. Raw slurry generally requires screening, solids separation, and process assessment before fine bubble aeration.

How many diffusers does a tank need?
The quantity depends on oxygen demand, airflow per diffuser, tank depth, basin shape, and the required mixing pattern.

Can it be used in an existing tank?
A retrofit is possible when tank access, piping, blower capacity, and treatment requirements are compatible with the proposed grid.
