Filter Press Building

Abstract

The high heat value of the plant's treated wastewater gave the economic edge to electric space conditioning, the major driver critical to the sale of the all-electric combination of space conditioning, lighting and modernization. With this head start in a heat source furnished by the "bath water" of the thousands of homes in the community, we were able to recommend a system of heat recovery refrigeration cycles that would provide space conditioning at a fraction of the cost of natural gas. The all-electric recommendation was accepted because it offered substantially lower operating costs and its concept matched the state-of- the-art theme of the project and was developed with the full cooperation of the consultant. The final design, a state-of-the-art sludge dewatering system, resulted in a project with a space heating system having an operating cost one-third that of natural gas, four times more efficient than commonly used systems, and a lighting system equal to or exceeding IES standards. In all respects, the "Filter Press Building" exemplifies the ultimate all-electric application.
