nnnn■SCREENING
nnnnITECHNOLOGY
nnnnThe initial step of the water and wastewater treatment plants is the mechanical treatment. Screening equipment
nnnnare the most important members of this pre-treatment process.
nnnnWastewater coming to the treatment plant will occasionally include wood, sticks, rags, and other debris in it.
nnnnBefore further processing, the wastewater must be screened to remove these materials, in order to protect the
nnnnchemical and biological processes. Also pumps, pipelines are protected by means of these screens.
nnnnNevertheless; although screening is acknowledged along with the physical treatment; as a result of their compact
nnnnconstruction and purposeful design; screening equipment can be used in various aspects of many applications.
nnnnAstim designs and manufactures manually cleaned or mechanically raked screens in a wide range of sizes and
nnnntypes for water and wastewater treatment plants and pumping stations. Astim design and manufacturing range
nnnnfor screening equipment covers;
nnnn• Manually Cleaned Bar Screens and Basket Screens
nnnn• Mechanically Raked Bar Screens
nnnn• Belt Screens
nnnn• Inline Screens
nnnn• Conveyor Screens
nnnn• Screening Treatment Systems
