Abstract

As a novel approach to solids removal, a dual chemical flocculation/ultrasonic method to clarify a whitewater stream was investigated. The technologyfirst considers the use of flocculants to create larger particles or flocs. Then, an ultrasonic field is applied to the flocs to obtain a clarified water stream and a stream of concentrated flocs. A laboratory ultrasonic separation system was used to demonstrate the clarification concept. Experiments at different flow rates, ultrasonic frequencies and acoustic intensity levels were made. Best results were observed using the flocculant system poly(ethylene oxide)/phenolic formaldehyde resin (PEO/PFR). A clean stream with less than 100 ppm of solids and a clarification efficiency close to 80% of the maximum achievable efficiency in the experimental setup were obtained. A preliminary economic assessment of the technology was performed.
