GRAF Carat S Septic Tanks

Floating and removable material is extracted from domestic wastewater in mechanical septic tanks. This is pure mechanical cleaning, for which you need 200 litres per person, per day of settling volume plus 80 litres person per year of sludge and scum storage based on AS/NZS1547.

Where additional separation between septic waste and treated water is required, the Carat S with baffle is the perfect option, providing a dual chambered design to separate untreated water from treated water before it is released.
