Water Resource Recovery Strainers
A proper water resource recovery system is used to effectively and efficiently reclaim white water, heat, chemicals, and fiber from a variety of paper and pulp mill applications, including DAF filtrate, save-all water, and seal pit water.
The RotoFlex resource recovery strainer uses a unique, patented method of filter media cleaning to keep the filter medium open and to flush contaminates from the surface. The conical media hangs freely from the upper support ring and is not attached or in contact with any part of the strainer below the ring. As the feed flow from the distribution headers impact the media and the media rotates, the synthetic mesh flexes back and forth, shedding the fiber and debris without the aid of a cleaning shower or scraping device. The feed flow helps wash the material to the center collection chamber for reuse or disposal.
The gravity strainer 4000 series technology is used for removal of suspended particulates. It is recommended for applications with total suspended solids of less than 1000 ppm and media retention requirements between 60-200 mesh (75-233 micron).
The VA strainer is an enhanced version of the gravity strainer. The unit will operate with influent total suspended solid loadings as high as 5000 ppm (0.5%), and with screen sizes as fine as 325 mesh (44 micron).
