Screening - 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...

Brief Description The PWL ProCat chain driven rake screen UR can be equipped and used as a wedgewire or perforated plate screen. This rake screen combines the advantages of the rugged and durable continuous belt screen with the hydraulic capacity of a screen with one active screening area only – such as step screens or spiral sieves. The PWL ProCat Rake Screen UR having an inclined screen offers a maximum flow cross section. The vertical screenings removal from the channel is very space-saving and highly efficient although it works without use of service water. For constructional reasons it is impossible that the screenings are carried off downstream. Function The waste water flows through the wedgewire screen made of flow-enhanced stainless steel triangular profiles. The screenings are retained, directly picked up at the channel bottom by rugged scraper blades and transported to the discharge area where they are scraped off resp. discharged. Wedgewire: 1 to 60 mm Perforation: 3...

Application An extensive reduction of the screenings volume by returning organic ingredients into the clarification process offers besides important cost saving with regard to screenings disposal advantages for the process stability of nitrification/ denitrification necessary in nearly all clarification plants. The company ABZ in Austria implemented decades of experience in the field of screenings treatment on the screenings washers. Many references attest the leading position of this technology by which the screenings weight can be reduced on average by 75 %. Special attention has been turned to the development of least possible wear and utmost operational safety. The Interval-Wash-Compactor can be operated with service water from the sand trap area. Peak loads of screenings due to storm water events are handled without problem, as well. Function The screenings are discharged directly or via a conveyor from the screen into the infeed hopper of the washer. After a pre-compaction...

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...
