排水、又は、脱水することができる。The present invention also allows for a rapid significant thickening of the sludge before it enters the dewatering process, particularly before entering the pressurized band filter.
As a result of the present invention, the capacity to weight of the device is increased and the device of the present invention can be fed with very dilute sludge containing on the order of 2 to 4 grams of solids per sentence. That is, dilute sludge from biological treatment ponds can be directly drained or dewatered without the constraints of relying on auxiliary equipment such as mud boxes or intermediate thickening storage devices.
