SEPTIC COMPLETE MECHANICAL PRETREATMENT STATIONS
SAU – SEPTIC COMBINED PRETREATMENT UNIT
The SAU – SEPTIC COMBINED PRETREATMENT UNIT system is a full customizable unit for the pretreatment of
the wastewater coming from septage truck.
This unit has been developed by FLUITECO for offer at the costumer the maximum performance in terms of
separation solid/liquid, keeping unchanged the durability, the resistance and the customizability typical of
The SAU1 – SEPTIC PRETREATMENT UNIT is the first variant of SAU and it’s composed by a screw screen in
tank with a rapid connection “Perrot” DN100 and a spherical valve with electrical connection.
Once activated, the basket of the screw screen capture the organic particles and transporting them upper
where they are compacted and then discharged for storage. The filtering zone, is constantly washed by
water because the organic material could stagnate on the sieve, so as to reduce odors.
The SAU2-3 – SEPTIC COMBINED PRETREATMENT UNIT are the other two variant which offer the combination
of two and three wastewater treatment operations respectively.
The operation is entirely similar to that of WAU, the waters, after the coarse filtration generally performed
by a screw screen in the filter tank, stagnant in the main tank, where the smaller size of waste are collected
by the transport and extraction screw.
The degreaser system normally present only in the SAU3 remove the grease from the water surface thanks
to the blower grit/fat separation.
