and Services
Virtually all water treatment processes require a solid liquid separation unit operation, including reverse osmosis desalination. SLS technology has expertise in the selection an application of chemicals and equipment for this purpose. Be it from removing toxic microscopic bacteria for drinking water, such as Giardia or Cryptosporidium to dewatering of dense phase mineral slurry.
Fabric media filtration equipment is a superior alternative to traditional forms of filtration, such as Sand filters, Diatomaceous Earth, Zeolite, Activated Carbon and Anthracite, disc and membrane micro filtration. It delivers identical separation with logarithmic magnitude quantum leaps in two critical cost parameters, flux rate and operating pressure.

APPLICATIONS Swimming pool filtration Using a higher separation performance filter not only produces
a more attractive pool it enables a direct reduction in disinfection
costs
Aquaculture Fabric media filters are used in raw water intake filtration,
recycling bio-filtration filters and discharge water applications.
There are many examples of marine and fresh applications. Fabric media filters are used to remove silt particles that cause erosion and blinding of dripper and misting outlet nozzles. The technology also successfully removes toxic pathogens such as blue green algae.
The following are examples of installations of the technology.
Reverse Osmosis plants Fabric media filters are applied as pre treatment filters to reduce permanent membrane blinding, installation of such filters have proven to extend desalination membrane life by 200 percent. Micro membrane filtration plants Installation of a high speed fabric media filter usually with a filtration well above 50 m3/m2/hr removes large particles and decreases membrane operating pressure by as much as 90% and extends the period between backwash by 1000 percent.
Installations of Fabric media filters include primary sewage, secondary and tertiary treated filtration tasks. Primary sewage can be filtered to reduce volume flowing through a plant operating at peak capacity, whilst secondary and tertiary effluents are filtered to provide either acceptable discharge limits or recycled water product.
Applications include acid or alkali liquor filtration in fresh water and hyper saline liquor environment. Filtration of viscous highly concentrated liquors is highly practical. The ability to provide high quality filtration via a media bed over a wide range of chemical and thermal conditions is enabling process engineers and hydrometallurgist to reconsider traditional process route strategies. Slurry filtration can be performed with integrated thickener filters. Whereas traditional gravity thickeners may operate between 1 and 40 m/hr rise rate, an integrated fabric media filter can operate at flux rates between 100 to 400 m/hr, a huge quantum improvement providing significant reduced capital and performance benefit opportunities.
