“…Similarly to MF, the flux through the UF PVDF membrane (150 kDa) decreased by 29% from 7.5 to 6.0 l•m -2• h -1 within the first 8 h until it became relatively stable. The obtained permeate fluxes are lower than those previously reported for both undigested and digested manure, namely 15-20 l•m -2• h -1 and 20 l•m -2• h -1 , respectively [37,38].…”

“…Since a wide range of animal waste treatment based on the experience in treating other concentrated industrial waste were applied in pig slurry treatment the engineered animal waste treatment systems require reclamation of chemical and biologically safe nutrient-rich solids, processed water, biogas for energy, and reduction of odor. To address this requirement, many researchers focused on developing efficient unit processes for alternative treat-ment schemes instead of traditional methods [2][3][4][5]. The most recent approach includes integrated microalgal culture system to treat livestock wastewater which is an efficient implication to reduce the cost of biodiesel production and provide an environmental benefit of microalgal bioremediation [34].…”

“…Superficial velocity in EGSB is higher than in UASB due to a high height to diameter ratio and a high recirculation rate. Consequently, these characteristics improve the mixing and the contact between the wastewater and the sludge in the EGSB reactor [3,11,12].…”

“…As large centralized livestock production leads to large production of manure, centralized biogas production by anaerobic digestion is of growing interest as a green energy solution in areas with industrialized livestock production. Anaerobic digestion stabilizes and converts about 20-25% of the organic matter present in animal manure into biogas; it is considered a reliable source of bioenergy and it minimizes greenhouse gas (GHG) emissions and odors [2][3][4]. Anaerobic digestion mineralizes some of the organic nitrogen and increases the NH 3 /NH 4 + content by about 15%.…”

“…Several studies have already proved that membrane separation is suitable for concentrating digestate liquid fractions [2,[10][11][12]. Microfiltration has proved to be a reliable technique for treating digestate liquid fractions and removing suspended solids from the liquid stream [10].…”
