The design of a MBR plant involves a good knowledge to consider different and integrate aspects interconnected: to the quality effluent requirements, the characteristics of the company or municipality that generates the wastewater, biological processes, ultrafiltration processes and equipment design.
MBR concepts of interest:
The implementation of a properly designed pretreatment step is critical in MBR plant design to ensure adequate protection of membranes from physical damage, minimize fouling and clogging and the need for cleaning operations.
Preliminary treatment consists of some of the following steps: screening, grit removal, septage handling, odor control, fats and grease removal and flow equalization
A complete ultrafiltration unit in MBR application needs several elements that have to be properly designed for an efficient functionality of the membranes. The main elements to consider in the design of an ultrafiltration unit are:
Other elements con consider to help Membrane Maintenance:
