Salher products

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.

The DE-LA lamellar, Salher brand, is a device designed for the continuous settling of suspended sediments transported by wastewater for flows comprised between 5 a 100m³/hour. By installing lamellar modules in the sedimentation chamber, it is possible to increase the effective surface area of settling, which allows to increase the performance of the settler and significantly decreases the surface area of the tanks producing more compact equipment with a greater efficiency. The lamellar settler is an internally demountable equipment to facilitate the extraction of the lamellar set.

There are two models of truncated cone shape settlers: the closed solids settling tank CVC-DC-TC and the open solids settler CVA-DC-TC. Both equipment have a truncated cone shape, they are manufactured by Salher in glass fiber reinforced polyester with orthophtalic resins for underground installation and they are used for the elimination of suspended solids. The closed model has an intake in the manhole to install a ventilation pipe.

The Imhoff tank CHC-IMH, Salher brand, is a settling-digestion equipment made of glass fiber reinforced polyester with orthophthalic resins according to EN-12255-4, which is used for the removal of suspended solids, with yields of 70 to 75%, and yields of 35 to 40% in the elimination of organic matter. This equipment includes a longitudinal deflector screen.
