CM-151* Ceramic UF Membrane Module

Ceramic Membrane explained

Ceramic Membrane Product

Ceramic membranes are not all the same. Nanostone’s engineers have developed a ceramic membrane to outperform other ceramic and polymeric membranes on the market today.

Advantages:
  • Comparable capital cost to polymeric UF
  • Best in class life cycle cost
  • Open platform / universal rack compatible
  • Independently tested and certified for ANSI/NSF 61 & 372 for drinking water
  • Optimized hydraulic design for water applications
  • Ceramic lasts 2x to 5x longer
  • Less fouling potential and less repairs
Side port - ceramic membrane

Duplex 2205 permeate side port for high corrosion resistance, strength, and long life.

Surface area - ceramic membrane

24.3m2(262 ft2) of active surface area α-Al2O3 ceramic membrane.

Pore size - ceramic membrane

Nominal 30 nm (0.03 micron) membrane pore size rating through specialized ceramic nanotechnology coating.

Segmented design - ceramic membrane

Patented segmented design optimizes hydraulic flow during backwash to improve performance.


Ceramic UF vs. Polymeric UF/MF Membrane Cost Model

Below is a techno-economic model to estimate the 10 year operating cost and cost of water for a 3 MGD (500m3/hr) industrial waste water reuse plant using UF/MF membranes designed to treat effluent from an existing conventional biological treatment system. The model assumes a 10+ year life for the ceramic membranes and a 4 year life for the polymeric membranes.

Overall a system using Nanostone CM-151*:
  • Matches up front capital cost of polymeric UF
  • Saves $1 Million in operating cost over 10 years
  • Results in a >30% cost of water savings
  • Provides a 2 million gallon savings of water every month

When the capital expense is the same, and you save the cost of buying two sets of replacement polymeric membranes as well as a substantial amount of water savings, the Nanostone Ceramic advantage is crystal clear.
