Water reuse

Final filtration or tertiary treatments are more and more required, in consideration of the more demanding regulation for water effluent quality, in relation to suspended solids. Final filtration systems also allow water reuse, both in industrial or agricultural application. Giotto Water offers the disc filter and sand filter, according to the required suspended solids content in the effluent.

DISC FILTER NDF / SDF *

The machine consists of one or more filtering discs, fixed on a robust central drum. The waste water flows through the central drum and then is transferred into the center of each media panel. A quick and efficient backwashing system starts automatically once the prefixed level of water is reached. The modular design as well as the possibility to use different kinds of filtering elements (stainless steel or polyester), allow to satisfy the highest filtration requirements.

Filtering panels

The panels are available in three kind of filter cloths, according to the specific needs of the requested application:

filtro-1

Patent flat panel in Aisi 316L with higher performances in terms of treated flow and strength

filtro-2

Patent flat panel made of polyester

filtro-3

Patent “pleated” panel with polyester mesh that provide 40% more surface area at equal number of discs

Each disc can be easily replaced in a matter of seconds, simply by loosening the locking screws. The panels can be easily and fast removed with no need of emptying the tank or disassemble the filter.

SAND FILTER – ASF

Sand filters, with a bed of sand – or sand and anthracite – operating by gravity without the need of backwashing pumps, thanks to an automatic system activated by siphons. Available in single bed or in two beds design, one placed on top of the other, operating in parallel, which allows to double the flowrate treated in the same space. It is also available in the “Combi” version, with the two beds operating in series: the upper sand bed for the removal of suspended solids and the lower one, with activated carbon, for reduction of the residual BOD.
