Founded in 1878, JRS RETTENMAIER & SOEHNE GmbH+Co KG is a global dynamic leader in the fiber and organic filter aid industry. JRS organic filter aids helps to save cost and improve production performance for companies doing precoat filtration, commonly found in the following areas:
- Chemical and pharmaceutical industry
- Food industry
- Beverages, fruit juices and liquors
- Metal-processing industry
- Waste water technology and sludge treatment
Through intense research and development, the former grain and saw mill has expanded dramatically incorporating specialized, highly technical pulverizing, fractionating and refinement processes. Today they have 18 manufacturing facilities located worldwide to supply the international market with fibers and organic filter aids.
Application areas for organic filter aids
Economical alternatives to diatomaceous earth and perlite.
Mineral products (such as diatomaceous earth and perlite) had the major market share in precoat filtration for several years but are now being rapidly replaced by JRS organic filter aids due to its significant economical savings
Bleaching earth additive to enhance performance
Bleaching earth is excellent at removal of coloured pigments (chlorophyll, Carotene and their derivatives), but it’s filterability of bleaching earth is very poor and its adsorption capability for polar substances (such as soaps, phospholipids and metal) is limited. Adding organic filter aids to bleaching earth will solve these problems.
Benefits of Organic filter aids
- Light weight material leading to low consumption, less fluid or filtrate loss and less waste
- Correctly shaped and sized particles leading to faster flow rates, longer cycle times, faster time to precoat, less particle break through and easier cleaning of filter screens
- No crystalline components making it physiologically harmless and non-carcinogenic
- Fibers are soft leading to no abrasion on pumps, pipes.
- 100% organic making it environmental friendly, suitable for incineration (high calorific value), animal feeding and a valuable organic matter in soil
JRS organic filter aids are made from cellulose which is a natural and renewable raw material. Using a finely tuned interplay of different production steps, tailor-made products can be manufactured for practically every filtration job. The intelligent use of the most different raw materials leads to a wide range of high performance filter aids.
