Technology / Service Summary
Pre-treated Trickling Filter System (PTF) method was developed to be suitable for wastewater treatment in developing countries featured by low energy consumption and the system flow is composed of three proprietary technologies with respective characteristics (high efficiency solid-liquid separator, new type trickling filter, final solid-liquid separator) by making our endeavors to improve a conventional trickling filter process.
The characteristics of the system are as follows.
１）Low energy consumption：the system is designed to achieve energy-saving in comparison with Conventional Activated Sludge Treatment Process, since the system has no aeration process which consumes substantial energy.
２）Stable treatment performance on effluent quality：the system can perform stable treatment in removing pollutants such as BOD, SS by adopting efficient filtration process (final solid-liquid separator).
３）Easy O&M: the system doesn’t require skilled engineers, who need to control
supplied air flow (volume) as well as sludge concentration to be monitored under Conventional Activated Sludge Treatment Process.
４）Minimum footprint：Each tank is designed to be compact by adopting high rate (speed) trickling filter as well as filtration equipment instead of sedimentation basin.
The system can perform treatment as competitive as other technologies such as Conventional Activated Sludge Treatment Process, Oxidation Ditch Process and Sequencing Batch Reactor Process, and on top of that, it will provide users (clients) with substantial benefit of lower life-cycle cost (LCC).
