Product Description

SS304 Stainless Steel Dissolved Air Flotation Machine for Corrosive Wastewater

This SS304 Stainless Steel Dissolved Air Flotation (DAF) Machine is purpose-built for industrial wastewater treatment scenarios demanding uncompromising material integrity and long-term corrosion resistance. Fabricated entirely from premium-grade SS304 stainless steel with optional SS316L upgrade availability, the unit withstands prolonged exposure to acidic effluents, alkaline cleaning solutions, and chloride-rich water streams without degradation. The fully welded tank structure eliminates leakage risks while the smooth electropolished interior surfaces minimize scale buildup and simplify routine cleaning procedures.

At the core of this system lies a high-efficiency pressurized dissolved air mechanism that saturates recycled effluent with compressed air before releasing it through precision-engineered nozzles, generating a dense curtain of microbubbles measuring 10 to 50 microns in diameter. These microscopic bubbles attach themselves to suspended solids, emulsified oils, and colloidal particles, lifting them to the water surface where a motorized scraping assembly continuously removes the accumulated floating sludge into a dedicated hopper. The result is crystal-clear treated water suitable for discharge compliance or downstream polishing in membrane bioreactors and reverse osmosis units.

Key Features

Full Stainless Steel Construction: Tank body, internal baffles, weir plates, and fasteners all manufactured from SS304/SS316L for complete corrosion immunity across the entire wetted surface area.
Precision Microbubble Generation: Counter-current dissolved air saturation vessel operating at 0.3-0.5 MPa delivers bubble diameters consistently within 10-50 microns for optimal particle adhesion.
Powered Surface Skimmer: Variable-speed motorized scraper assembly with adjustable blade height continuously transfers floating sludge to the collection trough without reintroducing solids into the clarified effluent.
Adjustable Hydraulic Configuration: Modular inlet distribution baffle and lamella plate arrangement allows fine-tuning of flow patterns to match fluctuating influent characteristics throughout daily operation cycles.
Integrated Chemical Pre-treatment Zone: Built-in rapid mix and flocculation chamber enables inline coagulant and polymer dosing directly upstream of the flotation cell for enhanced removal efficiency.
EPDM-Grade Sealing System: All gaskets, O-rings, and mechanical seals utilize chemical-resistant EPDM elastomers rated for continuous immersion in pH 4-10 wastewater streams at temperatures up to 60°C.
Pre-wired Control Enclosure: IP65-rated electrical cabinet housing motor starters, thermal overload relays, emergency stop circuitry, and terminals for optional PLC integration simplifies on-site installation.

Applications

The stainless steel DAF machine delivers exceptional performance across industries where corrosion resistance defines equipment longevity. Electroplating facilities processing acidic nickel and chrome rinse waters rely on the SS316L variant to prevent pitting and intergranular attack. Food processing plants handling citric acid-based cleaning solutions and high-temperature washdown water benefit from the hygienic non-porous surfaces that inhibit bacterial colonization.

Pharmaceutical manufacturers requiring ultrapure process water trust the inert material properties to eliminate metal ion contamination risks. Tanneries, textile dye houses, and chemical synthesis operations with aggressive solvent-laden effluents also specify stainless steel construction for uninterrupted year-round operation. The system integrates directly with existing equalization tanks, pH adjustment systems, and downstream biological treatment stages for a complete end-to-end wastewater solution.

Packaging & Quality Assurance

Every DAF unit completes a factory acceptance test including hydrostatic pressure verification and full-speed operational trial before crating. The equipment is secured inside a reinforced export-grade plywood shipping crate with internal bracing, vapor-barrier film, and silica gel desiccant packs to prevent condensation damage during maritime transport. All flanged connections receive protective covers while rotating components are locked in position.

Shipment includes printed installation blueprints, a detailed operation and maintenance manual, material test certificates for all steel grades, and a recommended spare parts list. Our standard 12-month manufacturer warranty covers defects in materials and workmanship, with optional extended coverage plans and on-site commissioning services performed by certified field engineers available worldwide.
