Technology

We manufacture our membrane and substrate from Alpha Silicon Carbide (SiC) on a flat sheet structure. This provides some unique advantages in water treatment:

  • High flux rate reduces footprint, energy & chemical consumption

  • Chemically inert provides high chemical resistance

  • Negatively charged surface reduces fouling of organics and oil

  • Extremely hard & durable makes it easy to clean

  • Simplified flow sheet no need for pre-sedimentation

  • New Process opportunities not used before with membranes (Ozone, Powdered Carbon, Pressure washing, etc.)

high flux rate

Cembrane membranes demonstrate an unprecedented high flux rate. This is mainly caused by the high surface porosity and the low contact angle to water.

A membranes contact angle to water is an accurate measure of how hydrophilic a membrane is. The more hydrophilic the membrane surface the higher the operating flux rate. This results in:

  • 3-10x the flux compared to polymeric

  • Unmatched low footprint

  • Low pressure operation at high flow

  • High recovery rates

  • Applicable for high sludge concentration

See video below demonstrating the difference in flux rate between Cembrane and a polymeric membrane.

Chemically inert membrane material:

Silicon Carbide has complete chemical resistance. This provides a range of benefits in various applications:

  • Can operate in extreme environments 

  • Durable & reliable operation

  • Fast and easy restoring of permeability

  • High resistance to wide a pH range, oxidants even ozone

Low fouling potential on Cembrane’s membrane surface:

Due to the negative charge of the membrane surface on a wide pH range, the membrane is less prone to fouling and clogging and allows for less maintenance equirement.

This effect is further enhanced by the high surface porosity of Cembrane’s SiC membrane. With a surface porosity more than 4x of commonly used membranes, the individual pores experience lower solids loading even at higher flux rates. See more in the video below:

 
 
 
 

DURABLE AND EASY TO CLEAN

Another critical feature of Cembrane is the hardnesss and durability of the membrane material, providing a long life and enables harsh mechanical cleanings, see below:
