Abstract: The invention is a system and method for converting paper forms to electronic data. More specifically, a special purpose system and technique are described for performing the conversion in a manner that is advantageous in terms of overall cost and cycle time. The approach is applicable to many different form types; the forms may be credit card applications, license applications, or tax returns, for example. Because present day scanners and character recognition algorithms still result in read errors, manual data correction is required. One technique described in the invention is how to efficiently use both internal and external data entry operators as part of an overall conversion process. The invention also illustrates how to apply contingent workflow management concepts to the data conversion process. The result is a more efficient and effective business process.

Abstract: A system for treating wastewater includes a basin to contain wastewater, an aerator provided in the basin to mix the wastewater, and a cover system to cover a surface of the wastewater contained in the basin. The cover system includes a plurality of hollow bodies disposed on the surface of the wastewater. Each hollow body is adapted to float on the wastewater's surface, and has a contiguous outer surface and a sufficient mass so that 30 to 70 percent of the hollow body's outer surface is exposed to atmosphere during use. A method of treating wastewater is further disclosed.
