Pulp & Paper Filter Equipment

Industries

Compositech's pulp and paper mill customers regularly use vacuum filtration equipment for fiber recovery and for sludge dewatering. Paper mills use disc filters as savealls to recover fiber lost in the paper making process. Additionally, disc filters are used as stock thickeners in both pulp and paper mills. A lot of pulp and paper filtration equipment also uses gravity tables and belt press filters for sludge dewatering and AES strainers in conjunction with savealls and deckers for polishing shower white water and for removing felt hairs from recycled press water.

Compositech's rotary vacuum disc filters are used for filtration in many processing industries including pulp and paper industrial water filters. Disc filters are versatile and provide reliable, continuous liquid-solid separation, however they do require major operator attention and a high volume of synthetic wire sector cover replacement due to the high tonnage of abrasive materials being filtered.

In addition to the vacuum disc filters we manufacture, Compositech supplies improved replacement parts for other disc filter brands. Compositech manufactures a stainless steel centershaft successfully used by our pulp & paper filtration equipment clients to replace the cast iron centershaft supplied with most disc filters. The proprietary design of our centershaft features custom made radial rod sockets and tubing for the drive end trunnions. All filtrate tubes and trunnions are 100% seal welded before machining to ensure a smooth, leak free finish. All filtrate tubes are individually removable from the centershaft allowing for easy repair and replacement without requiring complete disassembly of the filter. We design our centershafts to meet or exceed the quality of the original equipment manufacturer. Most recently, we built a replacement centershaft for an Eimco® disc filter. This Compositech designed and manufactured centershaft, measures 33 inches in diameter with a length of 28 feet, 9 inches.
