Dissolved air flotation unit Vespa series

Salher designs and manufactures the Vespa dissolved air flotation unit to separate suspended solids, grease and oils from wastewater. This system separates the particles in suspension by air microbubbles in a supersaturated concentration. The solids adhere to the microbubbles in their upwards floating path towards the scraping system. The equipment achieves a performance of 50-80% in BOD5 elimination, 60-80% in COD elimination and 90% suspended solids, oils and grease removal. Vespa is a fully modular and compact equipment, with adaptable layouts and deliverable worldwide, fitting perfectly in standard maritime containers. Flotator The main feature of this DAF, compared to others models of the market, is the cylindrical shape of its customized flotator; its height can be customized to adapt to the needs of each client. It also has a leveling system with adjustable supports for uneven grounds. This DAF is manufactured by Filament Winding system with an innovative material, a GFRP that combines isophthalic resins with basalt fiber, materials that prevent from corrosion and protect from UV radiation, providing the equipment with a total chemical and mechanical resistance to any type of adverse situation. Metallic elements are all made of AISI 316 stainless steel: a skimmer for floating particles collection, a flexible scraper system and a clarified water collector with adjustable height conforming an equipment easily adaptable to changes of incoming water loads.
