Sludge Dewatering Box in Practice

We present to you a new video contribution in which you will find everything you need to know about the use, installation and operation of the sludge dewatering box. The video shows the installation and use of the dewatering box for an older TOPAS wastewater treatment plant. You will learn all about the construction of the box, installation options, how to perform a sedimentation test, when it is necessary to desludge the treatment plant, and how the desludging itself takes place. At the end of the post, you will see what dried sludge looks like, how it is removed from the box and where it can be transported to. We believe that this video will assist you in deciding whether to acquire a dewatering box for a new or older TOPAS wastewater treatment plant. The video is in the Czech language. read more
