Performance Characteristics

MEMROD LT™ - Performance Characteristics
  • Extensive BOD5 and nitrogen removal due to high sludge age
  • Very low excess sludge production thanks to high sludge age
  • No need for a secondary settling tank due to the use of membranes
  • Solids-free effluent
  • Complete retention of biomass in the activated sludge tank
  • No need for the disinfection stage normally required in other processes
  • Compact design, adapted to the conditions on ships
  • Very low energy consumption due to the low pressure difference of 0.6 bar maximum across the membranes
  • Low capital outlay and low operating costs plus low-maintenance operation
  • Ease of operation due to fully automatic control systems
  • No odour emissions
  • Permanent availability due to the use of membranes
  • Self-cleaning membrane surfaces due to rising air bubbles
  • Stable cleaning performance, even with varying influx condition
