Abstract

The studies on technological development of polyvinyl alcohol (PVA) gel beads for bacterial immobilization and anaerobic bacterial gel beads for wastewater treatment have been done successfully. Results from the various experiments showed that the produced PVA gel beads have good permeability and elasticity, strength and stability in environmental condition of pH3 and pH10. With 3mm of size, the gel beads have an specific weight of 0,174 g/mL, porosity of 83,3% and hydraulic magnitude of 75 mm/s. The produced anaerobic bacterial gel beads have shown a good biological properties such as enhance the adaptation and stable treatment efficiency (greater 80%) of the reactor within the short time (16 days); reach the biogas production yield of 1,048 L/gTOCremoval, thus, showed the great potential application in anaerobic wastewater treatment facilities.

Keywords: PVA; anaerobic bacteria; gel bead; bacterial gel bead.
