Combination of technologies in a single device!
The GFAD MAX Gratt combines technological innovation with robust engineering. The definitive solution for companies seeking maximum operational efficiency.
The GFAD MAX Dissolved Air Float is the new generation of flotation systems from Gratt, developed for treating water and industrial effluents with high solid-liquid separation efficiency. Designed to maximize clarification, remove suspended solids, oils, grease and organic matter, the equipment combines robust engineering, simplified operation and high reliability, ensuring continuous performance and rapid return on investment.
The integrated construction concept reduces installation area, facilitates field assembly and ensures superior hydraulic stability, making the GFAD MAX ideal for industrial plants that require high performance, low operating costs and long useful life.
How does it work?
The equalized effluent goes through coagulation and flocculation stages in static or hydraulic mixers. It is then combined with microbubbles generated under pressure, forming bubble-floc aggregates that reduce particle density. These aggregates quickly rise to the surface of the flotation tank, where they are removed by mechanical scrapers, while the clarified water passes through the separation zone and is collected for disposal or reuse.
The process provides high removal of COD, BOD, total suspended solids and oils and grease, delivering clarified effluent with high operational stability.
Advantages of the GFAD MAX Gratt Flotator
Differences
- Integrated Automatic Polymer Preparation Unit for precise dosing and homogeneous solution;
- High-efficiency pre-flocculation chamber for rapid formation of stable flocs;
- Advanced system for generating ultrafine microbubbles with uniform distribution;
- High-rate lamellar modules that expand the separation area and increase treatment capacity in a smaller footprint;
- Chemical dosing pumps incorporated into the skid;
- Plug‑and‑operate electrical panel with centralized control;
- Highly durable and corrosion resistant materials.
Applications
Applied in industrial effluent treatment stations, pre-treatment, secondary treatment and clarification of process water. Suitable for slaughterhouses, tanneries, dairy, food and beverage, textile, chemical, petrochemical, paper and cellulose industries, industrial laundries, fruit and vegetable processing, water recycling and ETA's.
Construction
The monobloc system provides greater structural resistance, better sealing and tightness, uniform distribution of mechanical stress and a significant reduction in failure points. The absence of multiple joints minimizes leaks, premature wear and maintenance interventions, resulting in safer, cleaner and more durable operation, even in harsh environments.
