1. Urban sewage
Using highly efficient mixed bacteria with flocculation and degradation effects separated from urban domestic sewage to treat domestic sewage can achieve a 100% removal rate of COD and BOD.
2. Building material wastewater
The former mainly contains a large amount of clay particles, while the latter contains clay particles and a considerable amount of glaze. After adding NOC-1 for 5 minutes, the turbidity of the body wastewater decreased from 1.4 to 0.043; the turbidity of the glaze wastewater decreased from 17.2 to 0.35; the turbidity removal rates were 96.6% and 97.9% respectively, and an almost transparent supernatant was obtained. Using flocculants produced by Rhodococcus rubrum to treat tile factory wastewater, the supernatant after treatment was almost transparent.
3. Other applications
Due to the safe and non-toxic characteristics of microbial flocculants, they have been gradually adopted in food wastewater treatment and have achieved satisfactory results. Furthermore, microbial flocculants can be widely used in the treatment of urban sewage, hospital wastewater, petrochemical wastewater, papermaking wastewater, pharmaceutical wastewater, and many other types of wastewater.
High efficiency and minimal residue that causes secondary pollution are important directions for future flocculant research and development. Safe, non-toxic, and highly efficient microbial flocculants are poised to replace traditional flocculants.
