Vacuum dewatering system KOLDRY

sludge

KOLDRY The patent-pending, highly efficient KolDry system is specifically designed for highly efficient dewatering of septic tank contents. The dewatering is effected by using flocculants and a drainage system capable of processing up to 50% more material than other existing systems available on the market. Thanks to the innovative system solution, up to 20 m³ per hour of sludge can be efficiently dewatered with a very high degree of dryness and very pure water is returned back to the tank. Through an ingenious screening stage, the solid material is dewatered and optimally prepared for disposal. Simple operation The unit is very easy to use. Septic tanks are emptied in the same way as with a regular septic tanker and, thanks to the IQAN process control system, the dewatering process is activated by simply pressing a button when the septic tank is empty. A camera is installed in the system, which makes it easy for the user to control the process. This is done by adjusting two parameters with joysticks. The rest is handled automatically. Process summary The sludge is sucked up from the tank Intermediate storage in the vacuum tank Flocculants are added Dewatering is effected via a screw conveyor and strainer Storage of solid material and final dewatering The water is returned to the septic tank The water is returned through the same hose used to suck up the sludge at the start of the process.
