In the treatment process of contaminated industrial or municipal water, a liquid sludge is accumulated. The high content of water in this sludge increases mass, volume and complicates transportation and disposal.
A screw sludge dehydrator is used to remove water, and it works with greater energy efficiency.
GRAN GARO offers automatic dehydrators suitable for operation in low and high humidity conditions.
Suitable for all types of sludge.
Prices for auger dehydrators are determined by the diameter of the auger, the number of augers in the device, the productivity of cake and liquid sludge, and power.
Save energy.
A dehydrator uses less electricity than a centrifuge or filter press.
Allow to fully automate the industrial process.
They are able to work around the clock, without stopping for washing or removing the cake.
Does not require operator presence.
The sludge is discharged automatically. Continuous purification allows reuse of up to 95% of water, which significantly reduces the costs of the entire complex. It is only necessary to observe and periodically remove the collected sludge.
Prevents overconsumption of polymer and flushing fluid.
Do not create any dangerous vibrations and noise.
Able to work 24/7
without stops for washing and cake extraction.
Sludge will be transported to the dewatering department after being thickend in the thickening department. In the advancing process, great pressure has benn produced due to the gradually decreasing filter spacing and screw distance, and the back platen clogging. Then the volume decreases continously, and the purpose of fully dewatering will be achieved.
