Advantages of PURON® MBR Technology MBR Technology vs. Conventional Processes
Improved Water Quality
- Meets stringent effluent requirements
- Filters out nearly all solids
Allows Wastewater Reuse
- As part of a treatment scheme, provides water for potable reuse
- Reduces wastewater discharge fees and freshwater costs
- Provides water for non-potable applications where fresh water is in short supply
Lowers Capital Costs
- Clarifier is not needed
- Biological step can be scaled down since bacteria concentration is higher
Reduces Plant Space Requirements
- Footprint is up to 50% smaller than conventional plant
- Allows for expanded capacity within existing buildings
Fewer Operational Problems
- Bulking and floating sludge problems are avoided
Why PURON® Technology is the Best Choice
Reduced Energy Demand
- Single header and centrally located air nozzles reduce aeration by up to 50%
- Lowest energy demand of nearly all commercially available MBR modules
Reduced Capital Costs
- Simple pre-screening due to low risk of module clogging
- Smaller aeration blowers due to lower air consumption
Higher Reliability
- More stable operation
- Single header design practically eliminates clogging at fiber tips
- Braided fiber reduces risk of fiber breakage
- Essentially trouble-free aeration system
Easily Retrofittable to Existing MBRs
- Few module connections
- Little need to modify infrastructure
Economical Cleaning and Maintenance
- Highly effective air scouring virtually eliminates sludging
