High strength wastewater treatment in a jet loop membrane bioreactor: kinetics and performance evaluation

Respirometric kinetic parameter calculations of a batch jet loop bioreactor treating leachate and oxygen uptake rate estimation by DTM

“…(5) and (6), are presented in Appendix A. The state equations describing the process are solved by using the related theorems and demonstrated in the following section.…”

“…Jet loop bioreactors, which are developed in parallel to the progresses in bioengineering, can treat wastewaters efficiently and relatively cheaper compared to the conventional treatment technologies [3][4][5]. These novel bioreactors have some advantages such as having an uncomplicated structure, operation simplicity, well-defined flow regimes, better dispersion impacts, lower power consumption, lower sludge production, improved quality of treated water with low turbidity and high mass transfer [5][6][7][8]. One of the most significant features these reactors possess is to achieve high dissolved oxygen concentration by means of the turbulence created throughout the reactor homogenously.…”

“…One of the most significant features these reactors possess is to achieve high dissolved oxygen concentration by means of the turbulence created throughout the reactor homogenously. It was reported that by means of these features high removal efficiencies were obtained for high strength wastewaters [5]. Therefore, leachate, with complex and unstable compositions, can be treated by this new technology.…”

Performance of the combined SMBR–IVCW system for wastewater treatment

“…Because it combines the advantage of conventional active sludge (CAS) and the predominance of membrane separation [2,3], this technology is especially fit for the high concentration or hardly degradable wastewater. As an aerobic biological treatment method, MBR can achieve good quality of effluent with low concentrations of TSS (total suspended solid), COD, ammonia and small quantity of microbes [4], but with poor removal rates of nitrogen and phosphorus [5,6]. Being an ecological wastewater treatment technology, constructed wetland (CW) was very practical with the low cost and easy management [7].…”

Absorption of a volatile organic compound by a jet loop reactor with circulation of a surfactant solution: Performance evaluation

“…For dissolving oxygen in the water, a JLR was found to be superior to other reactors in terms of the oxygen transfer rate per unit power input [30]. Since JLRs have another advantage of a small area requirement for installation, they have become increasingly important in chemical, biochemical, and even environmental process industries [31][32][33][34][35][36].…”
