20/3/2020, · Shale gas fracturing flowback fluid contains various degradation difficulty organic compounds after hydraulic fracturing. A hybrid treatment method was developed for treating flowback and produced water (FPW) using pre-treatment (NaClO) followed by the expanded granular sludge bed (EGSB) and moving bed biofilm reactor (MBBR).

For example, the reused ,flowback fluid, ratio of the Marcellus shale gas region has increased from less than 10% in 2008 to more than 70% in 2011, which has greatly reduced the water consumption (Rahm et al., 2013) Nevertheless, the New York environmental protection ministry recently announced the prohibition of hydraulic ,fracturing, operations in New York State, after a seven-year investigation.
