ASTIM - Picked Fence Scraper
Circular Sludge Thickeners are designed and manufactured for consolidating and thickening of sludge from primary, secondary and chemical treatment units. Circular Sludge Thickeners are manufactured to be installed at pier supported or peripheral carried fixed bridges. Generally fixed bridges are offered for using in small to medium sized tanks, in which the sludge has high concentration of solids. Also prier supported bridges with centre drive cage can be used for mining or heavy loaded primary applications. The main difference is thickeners with Picket Fence are improved to scrape heavier sludge and to obtain higher dry solid concentration so that the thickening rakes and stirrers are constructed against heavy sludge loads. For signal exchange silver or gold coated slip rings often used to obtain high efficiency in signalization.
Material: Carbon steel with surface protection or Stainless Steel.
