A combination of systems for pretreatment of wastewater (urban or industrial), including roughing and compacting, residue washing, sand removal, sand washing and degreasing.
Roughing with screening and pressing of refuse, including a first separation of solids, which are transported and pressed by the same system. It is made of AISI-304 stainless steel.
Washing in the screening zone: fmade up of a collector with diffusing nozzles and a slotted cleaning valve and collector.
Metal tank fitted with the following systems:
Sand trap-degreaser. Cell in which the sands, the greases and the supernatants are physically separated. The construction material is AISI-304 and AISI-316 stainless steel.
Aeration-emulsion breaking: Air injection for separation and washing of sands and for floating greases and supernatants by means of thick-bubble diffusers.
Compressor: Rotary for injecting air into the sand trap.
Sand extraction: A horizontal transporter which collects the sands precipitated in the tank and transports them to the tilted extractor screw. The construction material is AISI-304 and AISI-316 stainless steel.
Grease pumping: helical pump for pumping grease, coupled to a metal bed plate.
Electric panel for protection and control: for protecting and automating all the systems, including a palm button for emergency shutdown.
