APPLICATION CHALLENGES WE SOLVE

SeawaterRO desalting process requires a reliable and durable pre-treatment filtration with maximum
removal of suspended solids, turbidity, algae, bacteria, dissolved organics and TEP
GroundwaterTypically contaminated with heavy metals such as Fe and Mn which limits the use of conventional
sand filters
In special cases additionally contaminated with radioactive isotopes
Deep groundwater with water temperatures above 50 °C limits the use of conventional filtration
solutions based on polymeric membrane material
Surface waterContaminations from sewage discharge lead to increased organic as well as heavy metal
contaminations
Typically removal of suspended solids, turbidity, algae, bacteria and dissolved organics
In some cases addionally contaminated with arsenic
Municipal sewageConventional sewage treatment plants very often unable to match regulations for direct discharge
to environment
Focus on reuse of treated sewage effluent as new water source either for irrigation and
landscaping or pre-treatment for RO for other industrial reuse purposes requires further
treatment of biologically treated water to remove bacteria, suspended solids and dissolved organics
Industrial sewageLimited capability for biological treatment requires additional process steps for direct discharge to
environment
Very often contaminated with very high organic contents, oil and heavy metals
Industrial waterProduced water contains high concentrations of oil
Mining drainage water contaminated with heavy metals and carcinogenic toxins
