JRS (J. Rettenmaier & Söhne) is offering a wide variety of organic filter aids for almost all applications in industrial solid-liquid-separation. Just recently a new group of selective functionalized process aids had been developed, that is now covering even more needs of industrial users. All mentioned products are based on natural, regrowing raw materials, which enable users to often utilize their filter residues instead of having to pay for costly and environmentally damaging ways of disposal.
By using a well balanced sequence of sophisticated milling technology, followed by nifty classifying systems, tailor-made products from organic raw materials are available for almost all challenges and tasks within industrial solid-liquid-filtration.
Above mentioned "selective functionalized process aids" are brand-new on the market! After chemically modifying suitable organic raw materials and physical conditioning, resulting products provide selective properties (for instance adsorption, discoloration, etc.) in addition to the functionality of conventional filter aids.
Organic filter aids are just more environmentally friendly and, in addition, even more economical than their mineral competition!
Most important might be the fact that specific consumption of filter aids is significantly going down, when mineral filter aids are substituted by organic products. The latter causes a significant reduction of sludge quantities that have to be disposed of, which in practice, directly translates into enormous cost savings.
On the other hand, reduced sludge quantities also cause a reduced loss of process liquid, that is typically discharged with filter sludge. Especially, in case those liquids are of higher value, another financial benefit can be counted into total cost analysis.
Disposal of problematic filter residues is typically noticeably easier due to the high calorific value and the low ash content of organic filter aids. On the other hand, non-contaminated filter residues can be profitably utilized as animal feed, or in composting.
Due to the fibrous structure, rough surface, and large porosity of organic filter aids, higher flow rates and longer cycle times are most often be achieved. At the same time equipment such as pumps, pipes and conveyor elements is well protected, since organic fibers are soft and non-abrasive.
Due to their structure, organic filter aids act elastically against pressure drops. They bridge over small defects in the filter cloth, and through the fibers' internal adhesion, the later cleaning of the filter media is much easier. Finally, the lack of harmful crystalline components in organic filter aids insures against health hazards under normal usage conditions.
