Simultaneous removal of cyanobacterial blooms and production
A shipboard RDF coupled with CPAM flocculation is a promising approach to remove harmful cyanobacterial blooms and improve the water environment of eutrophic lakes. A mechanical harvesting technology based on coupling flocculation with a rotary drum filter (RDF, 35-μm) was applied to remove cyanobacterial blooms and produce Flootech Rotary Drum Filters can be combined with Dual Flow Basket Filters to provide complete intake solutions with very high filtration grades (35 50micron).

Rotary drum filters Chemical Engineering Beyond Discovery
Rotary drum filters. Because of its versatility and simplicity, one of the most widely used vacuum filters is the rotary drum filter and a filter of this type was patented in England in 1872 by William and James Hart. The basic design varies with different manufacturers, although essentially all drum type vacuum filters may be The outer surface of the drum is equipped with a stainless steel support net, and a filter mesh of 160 mesh or more is placed on the outer surface of the support net (depending on the diameter of the starch). The surface of the drum is effectively dehydrated to occupy about 70% of the entire drum area, and the blade edge is upward.(PDF) Rotary drum filter Pu Yang Academia.edu
