COMPACT SYSTEM FOR PRE-TREATMENT OF CESSPOOL SEWAGE
A completamento del processo di depurazione delle acque reflue civili o industriali esiste una serie di dispositivi realizzati interamente da COSME che supportano l’ impianto in ogni sua fase lavorativa costituendone parte integrante.
HOW IT WORKS
After connecting the tank truck to the quick coupling of the plant, sewage is feeded into the tank. Automatically, by suitable sensors, plant starts and begins the filtration.
Sewage passes through the self-cleaning filtering belt, which blocks the solid parts present into the waste, and convey them toward the discharge zone located in the top part of machine. Due to the particular shape of the filtering elements, there is a continuous self-cleaning of belt, which becomes much more efficient due to the counter-rotation of a brush and presence of washing nozzles.
Cleaning of tank and washing of solid material, to remove organic substances, are granted by spraying nozzles located on tank.
In case of overload, sensors activate a gate valve, which stops the sewage flow.
HOW IT IS BUILT
Bearing structure in cold-bent plate, FS filter (see sheet), all made in AISI 304 stainless steel.
Filtering belt composed by teeth in acetalyc resin installed on a certain number of parallel shafts (spacing between teeth will be chosen basing type of material to treat).
Gearmotor of FS filter.
Pneumatic gate valve with body in cast-iron body and lens in AISI 304, with solenoid valve of control.
“Fan” shaped spray nozzles with open/close solenoid valve.
Rod sensors for plant automation.
Electric panel of control and protection with automatism for plant.
