The mechanical activation of the dry polymer ensures polymer optimization and lowers operating costs. An innovative stainless steel "hollow wing" mixing impeller in the mix/hold tank reduces polymer consumption by providing proper energy at low speed through impeller size and recirculation to prevent agglomerations while minimizing polymer fracture. With minimal maintenance and a small footprint, the PolyBlend® DP is fully automatic and easy-to-operate.
UGSI Polymer Feed Systems
A PolyBlend M Series Polymer Feed System provides a tapered mixing chamber that provides high performance polymer mixing and feed. The PolyBlend® system applies high mixing energy at the first contact of polymer and water for a short duration on initial shear. The system also applies mixing through a tapered regime, which minimizes polymer agglomeration and fracturing. After initial wetting or inversion in the high-shear impeller zone of the unit, polymer solution passes through a cylindrical processing zone where it is subjected to continuously decreasing shear rates over a period of time. The unit is equipped with "C" Controls functions, which along with a variable speed mixer offers a system with unmatched activation flexibility. The controller is capable of maintaining constant solution strength by sensing changes in incoming make-up water flow and automatically responding to these flow changes via a motor-driven control valve. Even primary and secondary dilution water is kept at the same ratio as output is adjusted.
ClearStream Gasholder Cover - Radial Beam or Truss for a primary or secondary digester that allows for varying volumes of gas storage. Also allows varying levels of sludge as compared to the fixed digester cover and prevents a large scum blanket. The slide guides are low maintenance compared to rolling guides. This cover does not require external insulation because there is several feet of gas storage between the roof and the sludge for thermal insulation.
ClearStream- Buoyant Floating Truss Digester Cover is a primary digester cover preventing a large scum blanket since the cover is in direct contact with the sludge to reduce liquid area exposed. This cover is most effective when sludge levels vary significantly and in conditions where extreme foam occurs. The ballast blocks are located in the attic space where the attic space acts as natural thermal insulation.
ClearStream- Fixed Digester Cover - Radial Beam is economical primary digester cover with small liquid level variation and can also be used as a secondary digester when gas can be stored through other means. The fixed digester has a limited gas storage capacity. Designs incorporate a water launder or a seal to overcome liquid level variation limitations. The annular seal achieves a pressure seal utilizing sidesheets submerged in the sludge and contains odors.

This keeps transportation costs low.
Andritz - Belt Drying System - provides highly desired Class A Biosolids in a highly marketable sludge pellet / granule. The process granulates the dewatered sludge in a mixer with product that has already been dried. The moist granulate produced here is distributed evenly over the belt in the dryer by a specially designed feed module. The even layer of material on the belt creates optimum conditions for even distribution of the drying air. This, in turn, is necessary for even heating and drying of the sewage sludge. The layer of material on the belt forms a
filter medium for the air flowing onto the granulate layer from above and thus prevents entrainment of dust. The low temperature of the drying gases (< 150°C) and the low dust content in the system facilitate safe operation. The dried material is not exposed to mechanical stress during drying and is pre-cooled before the dryer discharge. The technology - simple, convincing, and successful.
