High Capacity Dissolved Air Flotation Machine for Large Scale Wastewater Plant
This High Capacity Dissolved Air Flotation Machine is engineered for large-scale industrial wastewater treatment facilities requiring consistent throughput of up to 150 cubic meters per hour. The oversized flotation cell features a deep rectangular tank geometry optimized for extended hydraulic retention, ensuring complete separation of suspended solids even under peak loading conditions. At the heart of the system, a dual-stage dissolved air saturation circuit pressurizes a portion of the treated effluent to 0.4-0.6 MPa, achieving near-complete air dissolution before controlled depressurization through a bank of precision release nozzles. The resulting microbubble cloud blankets the entire cross-section of the flotation zone, creating a buoyant lift force that rapidly transports flocculated particles to the surface for removal. Heavy-duty structural steel reinforcement throughout the tank body provides the mechanical rigidity necessary for continuous 24-hour operation in demanding industrial environments such as mining processing, pulp and paper manufacturing, and municipal sewage pre-treatment. The system is supplied as a complete package including feed pump, air compressor, chemical dosing skid, and integrated control panel for rapid deployment and commissioning.
Key Features
Industrial-Scale Throughput: Designed to process 30 to 150 m³/h of raw wastewater, handling hydraulic surface loads exceeding 6 m³/(m²*h) without compromising effluent quality.
Dual-Stage Air Saturation: Tandem pressurized dissolution vessels with counter-current packing media maximize air transfer efficiency, achieving dissolved air concentrations above 90% of theoretical saturation.
Reinforced Structural Framework: Carbon steel tank body with external stiffening ribs and cross-bracing resists hydraulic pressure surges and supports the full weight of the skimmer bridge assembly.
High-Torque Scraper Drive: Geared motor assembly delivering sufficient torque to move dense sludge blankets across the full width of the flotation cell without stalling or requiring operator intervention.
Adjustable Effluent Weir: Threaded rod weir plate mechanism permits fine-tuning of the water level relative to the skimmer blade position, optimizing sludge consistency in the collection hopper.
Quick-Connect Pipework: Flanged inlet and outlet connections with flexible coupling joints simplify integration with existing plant infrastructure and accommodate minor alignment variations during retrofitting.
Centralized Lubrication Points: All rotating bearing assemblies feature grease fittings accessible from the platform walkway, reducing scheduled maintenance time and improving operator safety.

Applications
The high capacity DAF system is purpose-built for industries generating substantial wastewater volumes that demand continuous treatment without buffer storage. Municipal wastewater pre-treatment facilities employ these systems to remove primary sludge and floating debris before biological secondary treatment, significantly reducing organic loading on downstream activated sludge basins. Mining operations utilize the high throughput capability for processing tailings pond water and mineral processing effluent containing fine suspended particles. Pulp and paper mills depend on the system for fiber recovery and white water clarification, achieving both environmental compliance and valuable material reclamation. Large-scale food processing complexes, including poultry slaughterhouses, dairy plants, and vegetable canning facilities, rely on the consistent high flow handling to maintain uninterrupted production while meeting discharge permit requirements for BOD and TSS. Refineries and petrochemical plants also deploy these units for bulk oil-water separation in API separator effluent polishing applications.
Packaging & Quality Assurance
Each DAF unit undergoes hydrostatic integrity testing and full-load operational verification before leaving our factory. The equipment is shipped in a reinforced marine-grade plywood crate with internal steel bracing, anti-corrosion VCI film wrapping, and humidity indicator cards to monitor transport conditions. All machined surfaces receive rust-preventive coating while electrical enclosures are sealed against moisture ingress. A comprehensive delivery dossier includes certified material test reports, weld inspection records, detailed assembly drawings, comprehensive operating instructions, and a preventive maintenance schedule. Our standard warranty covers 12 months from commissioning against manufacturing defects, with optional extended warranty packages and turnkey installation supervision provided by our field service team dispatched directly to your project site anywhere in the world.
