KMS Membranes Recover Acid and Caustic Solutions, Saving Both Material and Disposal Costs
Neutralization and disposal of caustic and acid solutions is becoming a less acceptable practice. At the same time, rising costs make reuse of these solutions through membrane recovery an attractive and cost-saving alternative.
Beverage Bottling
The caustic solution used to clean PET bottles for reuse can be recovered using membrane technology, reducing disposal and chemical costs.
SelRO® Beverage Applications
CIP (Clean in Place) Solutions
KMS can help design a membrane system that will reliably create clean solutions from your acid and caustic spent CIP solutions.
SelRO® Dairy Applications
SelRO® Pharmaceutical Applications
Copper Recovery in Electroless Solutions
Membrane technology filters the solution while recovering the costly metal salts for reuse, reducing both materials costs and disposal concerns.
SelRO® Electronic Applications
Debittering
Membrane technology can be used to recover the caustic solution used in debittering beer and citrus, reducing chemical costs.
Detergent Manufacturing Wastewater
Membrane technology allows reuse of the phosphorus acid used in detergent manufacturing, saving on both material and disposal costs.
Acid Recovery in Metal Processing and Finishing with SelRO® membranes
Fertilizer Processing Wastewater
Rather than neutralize the phosphoric acid from your fertilizer manufacturing process, membrane technology allows you to reuse the acid and reuse or safely dispose of the wastewater.
Acid Recovery in Metal Processing and Finishing with SelRO® membranes
Hydrometallurgical Metals Recovery from Ores
Dissolving ores in acid is one way to refine the metals contained in the ore. Membrane technology can then be used to separate the metals from the acid solution.
Acid Recovery in Metal Processing and Finishing with SelRO membranes
Mineral Acid Pretreatment for Metals Coating
Membrane technology can recover the mineral acid used for pretreating metal parts prior to the application of metallic or plastic coatings.
Acid Recovery in Metal Processing and Finishing with SelRO® membranes
Mercerization and Sandoflex Processing of Fabrics
The caustic solutions used in the mercerization and Sandoflex processes can be recovered and reused using membrane technology, for a low cost environmentally effective solution.
SelRO® Textile Applications
PVPP Column Regeneration for Beer Making
PVPP columns are widely used for removing phenolic compounds from beer. These columns are regenerated daily with a caustic solution that can be recovered and reused with membrane technology.
SelRO® Beverage Applications
Tomato Processing
Membrane technology can be used to recover the concentrated caustic solution used for peeling tomatoes.
