Why Use Organic Filter Aids?

In addition to their excellent separating qualities, organic filter aids are especially economical, can be disposed of in an environmentally friendly manner, and are medically harmless, reliable and highly effective.

 
 

Economical?

The specific use of organic filter aids is up to 70% less when compared with mineral products. In practice this translates to reduced consumption and significantly less sludge which is often associated with expensive and time-consuming disposal.

At the same time, reduced sludge contains less residual filtrate which translates into less product loss due to disposal of the moist filter sludge.

Filter sludge, which is made of organic filter aids, can be quite effectively compressed or even made into briquettes. In this manner, a large portion of the valuable residual filtrate can be recovered, which leads to even further savings.

Due to the fibrous structure of organic filter aids, stable and defined compacted material or briquettes are obtained which can often be profitably recycled.


Reduced consumption when using organic filter aids means ...   

  • less waste
  • lower disposal costs
  • less product loss

If the filter sludge is compressed, organic filter aids can lead to...

  • higher yields of recovered residual filtrate 
  • more stable compacted material or briquettes which can, in part, be profitably recycled 
  • less wear on the presses used for briquetting.

 
 

Environmentally-friendly disposal?

Since organic filter aids are completely biodegradable, the uncontaminated filter residue can be profitably recycled through use in crop production , composting or animal feed.

On the other hand, contaminated filter residues can be thermally recycled very economically due to the organic filter aid's BTU values as well as its extremely low ash content .

In individual cases, valuable materials can be recovered through the residue-free incineration of organic filter aids which are previously removed using a filtration process (example: catalyst filtration).

Organic filter aids...

  • can be disposed of easily, economically and, in part, even profitably
  • make it possible to completely recover valuable processing aids (such as catalysts)

 
 

Harmless from an occupational medicine point of view?

In contrast to many, conventional mineral filter aids which have been classified as "carcinogenic" for years the lack of dangerous, crystalline substances when handled in the recommended manner, ensures organic filter aids to be occupationally harmless.


 
 

Reliable and highly effective?

In practice, due to their fibrous structure, the jagged surfaces as well as the large pore volume, higher flow rates are usually obtained with organic filter aids as compared with mineral products.
At the same time filters last longer. Due to their structure the fibers react elastically to pressure surges. They bridge damaged spots in the filter material and through the use of an inner bonding make subsequent cleaning of the filter cake easier. Since organic filter aids are soft and nonabrasive, pumps, pipes and conveying elements are well-protected .
