PENGARUH VARIASI PENAMBAHAN Ca2+ TERHADAP PERCEPATAN PEMBENTUKAN DAN KARAKTERISASI MICROALGAL-BACTERIAL GRANULAR SLUDGE (MBGS) DARI AIR LIMBAH DOMESTIK

The increasing human population is directly proportional to the amount of
wastewater produced. The greater the use of water, the greater the domestic
wastewater produced. In general, domestic wastewater treatment uses activated
sludge. However, this treatment has several drawbacks such as not being able to
remove nutrients, requiring large electrical energy for aeration, and further sludge
handling. One of the new innovations in domestic wastewater treatment is the use
of Microalgal-Bacterial Granular Sludge (MBGS). MBGS has the advantages of
lower energy consumption, better settling ability, and lower greenhouse gas
emissions, and can effectively remove COD and ammonia. However, the formation
process of MBGS takes a long time, requiring the addition of Ca2+ which can
increase the stability of aerobic granules by forming bridges between EPS
molecules by reducing the overall negative charge on the biomass surface. This
study used 3 variations of Ca2+ concentration, PBR 1 (25 mg/L), PBR 2 (50 mg/L),
and PBR 3 (75 mg/L). The best result in this study was PBR 3 (75 mg/L) which had
a dense and compact MBGS structure with a diameter of 1.8-2.4 mm, VSS
concentration of 6.36 g/L, SVI5 of 36.9 mL/g, SDI of 2.71 g/mL, and COD and
ammonia removal efficiency of 96.04%; and 97.63%.
Keywords: Domestic wastewater, Ca2+, Chlorella sp., Microalgal-Bacterial
