The Bright Technologies Belt Filter Press is a modern design, that specifically includes three (3) US Patents and more importantly, innovative features that provide high performance in a compact, and high value package. Consequently, many competing products are based on old and inferior designs, and therefore, do not utilize filtration area effectively. Our Belt Filter Press is designed with long term value and ease of operation in mind. For example, stainless steel frame and roller construction are standard. An Allen Bradley touch screen and PLC integrate the press and support equipment, so that unattended operation and integration into SCADA systems are easily accomplished. Additionally, the optional press mounted operator walkways and handrails are easily removable for belt filter press maintenance and allow the operator good visibility of the process. There are three process zones to a Belt Filter Press, the gravity zone, wedge zone, and high/pressure/shear zone. First, the gravity zone is where the sludge or slurry is first introduced to the filter. This typically happens after a chemical flocculent or polymer has been introduced and mixed into the slurry to release water and form larger particles. Finally, the slurry is spread across the usable area of the filter and is contained from running off the filter sides by rubber seals. There are typically plows or chicanes on the upper surface of the filter belt to move the sludge solids and promote drainage. On the lower side, the filter belt is typically supported by a grid of replaceable plastic material.
