Contents  Moving bed (bio)filtration process features and applications  Strategic planning: future consents, combinations  Basis of design  Operational issues

Moving Bed (Bio)filtration operating window

MBF applications  tertiary waste water polishing for solids removal and biofiltration  process and drinking water production  cooling water bypass filtration  surface water direct filtration  refurbishment of existing plants, services

MBFs and strategic planning  Combined N& P removal  Future consents  Hybrid systems

MBF basis of design  washer assembly  hydraulically driven  fixed wash water rate  Airlift  driven by air supply  sand/solids separation  wear and tear

MBF basis of design  Solids load (kg/m 2 .h)  Biological conversion (kg N/m 3 .d)  Hydraulic rate (m 3 /m 2 .h)  Gas rate (Nm 3 /m 2 .h)

Aeration grid  Rigid frame  Fine bubble aeration  Laser cut slits  No disturbance  Homogeneous flow

Online filter monitoring  Online monitoring of sand circulation rates and more!  Proven RFID technology  Web based environment with online service backup

Efficiency by Sand-Cycle data (2) Distribution of circulation time for an optimized filter comparable to a DS5000 filter as at Simpelveld 19 5-6-2017 Parallel sessie 1, seminar 2

RFID Technology Data management important to fulfill higher performance  Inspired Brightwork to look at the RFID technology  RFID known by electronic cat lids, wildlife tracking and monitoring livestock Water sector  Sand-Cycle first application  Many more possibilities revealing the unknown black box of processes 20 5-6-2017 Parallel sessie 1, seminar 2

WwTP Wijlre the Netherlands • New plant completion 2017 • 20 stand alone filter units • Total filter area: 20 x 5 = 100 m2 • Design basis DWF+ for N < 2 ppm and o-P < 0.15 ppm • Sand-Cycle fully integrated 21 5-6-2017 Parallel sessie 1, seminar 2
