➤ Why grit separation? ➤ ➤ For the reason of operating reliability of wastewater treatment plants it is necessary to separate the grit transported with the wastewater and other mineral materials (approx. 60 l / 1000 m3 of wastewater) from the digestible organic material. Grit separation from wastewater can prevent operational problems, such as grit sedimentation (in aeration tanks and digestors), increased wear of equipment (pumps or stirrers), blockages (hoppers or pipelines) along with wear reduction of mechanical equipment (e.g. a centrifuge, etc.). The aim for the system is to separate...

➤ ROTAMAT® Complete Plant with Hydro Duct Ro 5HD ➤ ➤ WASTE WATER Solutions Design and function The ROTAMAT® Complete Plant Ro 5 HD combines the benefits of both aerated and unaerated grit traps by using a highperformance grit trap with a small overall plan area. The wastewater flows firstly through an inlet screen that retains, washes, compacts and dewaters the solids contained within the flow. The screened wastewater then passes into an aerated grit trap that reduces the settlement of organics within the flow by the action of an aeration system within the grit trap. Grease along with other...

➤ ROTAMAT® Circular Grit Trap HRSF ➤ ➤ WASTE WATER Solutions Design and function Separation of the grit particles in the HUBER Circular Grit Trap HRSF is supported by the rotational motion of the wastewater. The separation effect is generated by overlapping of the vertical downward motion and a developing centrifugal force acting on the individual grit particles. The inner tank surface serves as the separation area. To increase the separation area, the HUBER Circular Grit Trap HRSF has an additional separation cone for a reliable maximum separation performance. For improved separation of...
