Treatment of Textile Wastewater using Hybrid Biogranular System Contact: Assoc. Prof. Dr. Azmi Aris / Dr. KhalidaMuda Department of Environmental Engineering Faculty of Civil Engineering UniversitiTeknologi Malaysia
Highly colored wastewater from textile industry • High concentration of non-biodegradable organics, suspended solids, conductivity, turbidity and intense color
of the chemical in textile processing will remain on the fabric….. • 10%
will be discharged in textile effluent • 90% (IPPC, 2003)
m3 of textile wastewater are generated per ton fabric 80 -100 (Savin et al, 2008)
Conventional biological system fails to treat textile wastewater
Physico-chemical treatment is available but expensive in terms of chemical and operational costs
Environmental Regulations (Industrial Effluent), 2009 • Colour* • Std A – 100 ADMI • Std B – 200 ADMI *Color was not regulated in previous regulation
Features • Treat textile wastewater within relativelyshort periodof time • Simple yet reliable and proven effective (90% COD and color removal) • Use microorganisms rather than chemicals – no chemical sludge, environmentally sustainable INSPIRING CREATIVE AND INNOVATIVE MINDS
Basis of Technology • Anaerobic followed by Aerobic stage INSPIRING CREATIVE AND INNOVATIVE MINDS
Bioflocs Biogranules Use biogranules instead of bioflocs - higher biomass concentration and shorter sedimentation time Biogranules function in both anaerobic and aerobic Hybrid - requires only one reactor – small foot-print Excess biogranules (sludge) - stored or sold to other treatment plant - potential source of income INSPIRING CREATIVE AND INNOVATIVE MINDS
WHAT IS BIOGRANULES • Biogranules • Developed in the reactor under specific conditions • Irregular shape with smooth surface • Size of 2.3 + 1 mm in diameter as compared to 0.02 + 0.01 for flocs • Dense and compact with excellent settling property (approx. 80 m/hr) • Structurally strong INSPIRING CREATIVE AND INNOVATIVE MINDS
Singlereactor in sequencing batch-mode • feed anaerobic (9 hr) aerobic (3 hr) anaerobic(9 hr) aerobic (3 hr) settling (5 min) • Treatment can be completed within 24 hours
