Ceramic Flat Sheet Membrane for Drinking Water Treatment - Water and Wastewater - Drinking Water
Today ceramic MF/UF membrane filtration for treatment of drinking water is becoming more and more accepted as a viable treatment method. This trends is mainly driven by an increasing demand for a more effective removal of especially challenging feed water containing:
Details
- Radium
- Arsenic
- Fe & Mn
- Pathogens
- Suspended Solids
But also due to that especially ceramic flat sheet membranes have recently become a better techno-commercial solution compared to Sandfilters or Polymer membranes.
Applications
- Sandfilter upgrades
- Ground water
- Surface water
- Sandfilter backwash water
Features & benefits of SiCFM membrane
- Hydrophilic material → clean water permeability of 10.000 LMH/bar
- Anti-clogging → membrane repels negatively charged particles
- Chemically inert → no degration of membrane from any chemical or solvent
- Durable and robust → membrane material is the hardest manufactured material
Operation features & benefits
- Highly compact designs
- High recovery – close to 100% mass balance
- Minimal maintenance & simple operation
- Lifetime exceeding 10 years
- Resistant to solvents, oil, grease, high temperature & high pressure
- Low energy consumption
Why choose Cembrane
Reduced OPEX
Robustness provides low maintenance – Low chemical consumption compared to Sand filters – Low energy consumption through hydrophilic membrane material compared to other membrane materials
High Recovery rate
Because of the hydrophilic nature of the membrane as well as an ISO Electric point below Ph3, which repels negatively charged particles, an unmatched recovery can be achieved
Low Footprint
With operating fluxes reaching up to 1.000 LMH, a relatively small membrane surface is required enabling low footprint and compact designs with resulting savings on piping and civil works
High TSS tolerance and limited pre-treatment required (<3mm)
With a flat sheet configuration the distance between sheets is 6mm and more, depending on application, this allows for a high TSS in the feed water and limits pre-treatment requirement to <3mm screening. In fact, by using suction to filter water through the membrane a non-compressed cake layer is build on the membrane surface allowing for a high flux, a reduction of scaling on the membrane and improvement of permeate quality even further than what the actual pore size allows.
