Separators for liquids - Import export

PWL static screens provide high operational reliability in the static liquid solid separation for municipal and industrial applications particularly for the separation of fibrous and non-greasy solids. The PWL static screen is very economical and easy to use. The operation of the static screen does without an electric drive or other moving parts. In industrial sewage treatment plants the PWL static screen is known for waste water treatment. Industrial users such as paper mills, food processors, tanneries, laundries, malt houses, breweries, zoos, recycling plants and many other branches rely on the PWL static screen for product recovery and waste water treatment. The curved screen surfaces are basically removable and can be pivoted depending on the width of the static screen. A specially shaped edge at the screen guides the drainage water of the statically dewatered screenings into the discharge trough of the static sieve. Optionally, the PWL static screen can be supplied with a...

The externally fed TanFlow Drum Screen is characterized by its rugged and simple design, as well as by its small footprint allowing for installations with limited space. The TanFlow is employed where it is necessary to separate larger flows of liquid from solids – irrespective of industrial or municipal applications. Even oily and greasy media can be separated. Function The process or waste water reaches the sieve drum surface via the headbox. First, the liquid runs from the outside of the drum into the inside. Thus, the solids which are larger than the chosen wedgewire opening settle on the surface. Due to the continuous drum rotation they are transported to the scraper where a gentle separation of the solids is effected. The cleaned liquid flows after the separation process once again through the drum, this time from the inside to the outside (backwash) where it finally leaves the machine through an outlet pipe. Installation Examples municipal WWTPs wood...

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...

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...
