Membrane Filtration as an Alternative: Part 1 (2145 words) |
 | Microfiltration is loosely defined as a membrane separation process using membranes with a pore size of approximately 0.03 to 10 microns, a MWCO of greater than 100,000 daltons and a feedwater operating pressure of approximately 100 to 400 kPa (15 to 60 psi). |
| It is the "loosest" of the membrane processes and, as a consequence of its large pore size, it is used primarily for removing particles and microbes and can be operated under ultra-low pressure conditions. |
| The variables that should be considered in cleaning MF membranes include frequency and duration of cleaning, chemicals and their concentrations, cleaning and rinse volumes, temperature of cleaning, recovery and reuse of cleaning chemicals, and neutralization and disposal of cleaning chemicals. |
