The performance of SBBR for sewage treatment is investigated in a reactor of capacity 10 L. Conventional K1 kaldnes media (30%) was used as a bio-carrier. after acclimatization for 3 weeks, biofilm was developed on the surface of each bio-carrier. How to measure and control the thickness of biofilm developed on the surface of bio-carrier?
To measure the Biofilm thickness we normally take carrier direct under the Microscope and measure there.
To measure the Biofilm Biomass you take several carriers (Known Number) and scrape off the biofilm and suspend in a known amount of water. Ultra Sound can also get off the biofilm. Then you make TSS analysis on the water and calculate the Mass of the Scraped of Biofilm. The number of K1 carriers is the multiplied by the surface of 1 carrier being 0,0005 m2.
