Testing Capabilities of Candle Filters and the Effects on Scalability

Proper design of a solid-liquid filter requires a thorough understanding of all the variables within that process. Lack of this understanding can result in a filter that is inaccurately sized, leading to either wasted capital or inadequate throughput, both of which are cost inefficient. The most effective way to investigate these variables is to perform field tests with a filter that can produce scalable results under a wide range of process conditions. This paper demonstrates the benefits of performing field tests using a small-scale FUNDABAC® filter that is easily scalable. A case study is presented that validates the scalability between a lab-size and commercial-size candle filter.
