CLEANING OF CERAMIC ULTRAFILTRATION MEMBRANES AFTER FILTRATION OF HAY HYDROLYSATE

Hydrolysis of the lignocellulosic biomass results in release high-value chemicals that during industrial processing can be recovered with membrane technologies. To maintain an effective performance membranes used technological biomass, their regular cleaning is essential. Although several guidelines may found for cases organic fouling, data fouled by hydrolyzed limited. Current research aimed to evaluate physical (air backpulse) and common cheap chemical methods. The showed air backpulse alone had a minor (9%) effect on cleaning. alternation NaOH (1 %) solution NaClO (200 mg/L Free chlorine) was most approach effectiveness 95.1 % 50 nm 89 200 membrane, indicating filtration effectively cleaned using affordable accessible chemicals.
