Municipal wastewater treatment with corrugated PVC carrier anaerobic baffled reactor

“…High COD removal for CABR may be attributed to the growth of biomass on carrier media which utilized more organics for metabolism. Feng et al (2008) reported TCOD removal efficiency of more 75% using bamboo carrier media in ABR treating municipal wastewater at 28 + 1 °C at HRT of 24 h. Similarly, another study conducted by Zha et al (2019) reported COD removal efficiency of 75.06 + 3.56% using modified ABR for pretreatment of black water at 36 + 1 °C. So, our study results are consistent with the previous studies using modified ABR for treating municipal wastewater.…”

“…Startup phase facilitates microorganisms to grow and acclimatize in the reactor and thus develops pollutants-removal conditions in the shortest period of time (Zha et al 2019). Startup phase was conducted in batch mode, which took 90 days.…”

Comprehensive analysis of a zeolite‐packed upflow baffled septic tank using tracer tests and mathematical modelling

“…Nevertheless, the septic tank does not fulfill environmental regulations as its effluent commonly contains high concentrations of organic matter, nutrients and pathogens. Richards et al (2016) have demonstrated that they contribute as a source of pollution; hence, modified versions, such as the upflow baffled septic tank (UBST), have emerged, exhibiting better performance (Jorsaraei et al, 2014; Li et al, 2016; Santiago‐Díaz et al, 2018; Zha et al, 2019).…”

Simultaneous recovery of ammonium and total phosphorus from toilet tail water by modified palygorskite–bentonite clay

“…The fecal sewage from toilets including urine, feces, and flushing water is also called black water (Jin et al, 2018). Although the proportion of black water in wastewater is small, it can heavily pollute the environment with high concentration of chemical oxygen demand (COD), nitrogen, and phosphorus (Zha et al, 2019). We have previously studied the coupling of MFC and MEC with ABR and constructed an AMM coupling system to treat the fecal sewage (Liu et al, 2017).…”
