Brief Description The PWL compact unit MODULAR is a multifunction unit combining waste water sieving with the discharge of grit and grease in one compact system. Due to its modular design the PWL compact unit can be equipped appropriate to individual waste water conditions. Among all kinds of screens the MODULAR can be used with drum screens within the inlet area. The different kinds of solids are separately carried out of the unit for further treatment or discharged into a container. Function Via pumps or gravity flow the waste water reaches the headbox of the MODULAR. The screen integrated into the headbox discharges the separable solids from there either to the downstream PWL Interval-Wash-Compactor or into a container. The waste water charged with organic and sand runs off directly from the headbox into the aerated grit chamber. The free fats and lightweight substances reach due to the prevailing roller stream the integrated grease trap. The arising floating layer is...

Application An efficient and reliable fine sieving is essential not only for a comprehensive water recycling but for completely closed water circulations. For these applications, the Drum Filter MDF with mesh sizes between 25 and 2000 µm is the best choice. This filter offers a high capture rate at low operational costs during continuous operation. The choice between different cleaning media is part of the adjustment to the individual site conditions. In addition, different discharge devices and the level controlled drum rotation have to be considered. Function The Drum Filter MDF is a unit made of stainless steel, designed for liquid/solid separation within the field of process and waste water of various industries. From the Drum Filter’s inlet connection the waste water runs off into the filter drum consisting of a steel construction which is covered with a stainless steel wire gauze. The solids settle at the gauze and are transported upwards by the rotating filter drum. The...

Application Increasing fees for sewage water make high demands on in-plant sewage treatment plants. The internally fed sieve drum CenterFlow is a product to face manifold problems, designed for liquid/solid separation in the field of process and waste water of industries or WWTPs. Function The rugged sieve drum is the core of the CenterFlow. Here, the particles are retained and carefully dewatered for further discharge. Within the inlet chamber the flowing-in medium is homogenized and the flow velocity reduced. The tangentially approached sieve surface serves to efficient fine sieving even of high hydraulic loads. Due to the drum configuration the main task can either be a fast solids discharge or a slower passage through the drum if the retained solids are to be, in addition, washed or properly dewatered. With a constant rotational speed and a low drive power this sieve drum machine is a reliable component within the equipment of a plant. The high availability and the large...
