“…erefore, some researchers have suggested the use of innovative ammonia stripper reactors as a solution for e cient removal of ammonia. Among the innovative ammonia stripping reactors proposed were rotating packed bed [40], water-sparged aerocyclone reactor [41], and semibatch jet loop reactor [42].…”

“…e jet loop reactors can also be used for the conversion processes in treating biochemical wastewater. Farizoglu et al studied the treatment of cheese whey in a jet loop membrane reactor and achieved 84-94% of chemical [41]. e water-sparged aerocyclone gas-liquid contactor can be used to address two major drawbacks of the conventional packed tower, which are the process performance and the fouling problems in long operations.…”

It is noteworthy to highlight that ammonia nitrogen contamination in wastewater has been reported to pose a great threat to the environment. This conventional method of remediating ammonia nitrogen contamination in wastewater applies the packed bed tower technology. Nevertheless, this technology appears to pose several application issues. Over the years, researchers have tested various types of ammonia stripping process to overcome the shortcomings of the conventional ammonia stripping technology. Along this line, the present study highlights the recent development of ammonia stripping process for industrial wastewater treatment. In addition, this study reviews ammonia stripping application for varied types of industrial wastewater and several significant operating parameters. Furthermore, this paper discusses some issues related to the conventional ammonia stripper for industrial treatment application. Finally, this study explicates the future prospects of the ammonia stripping method. This review, hence, contributes by enhancing the ammonia stripping treatment efficiency and its application for industrial wastewater treatment.

“…Water-Sparged Aerocyclone Reactor is another alternative. This process could efficiently remove ammonia nitrogen by 91%, along with total phosphorus by 99.2% and COD by 52% (Quan et al, 2011). In simple terms, this process is an aerocyclone; water is splashed in an air flux which results in increased surface conduct of liquid–gas phase (Xuejun et al, 2009).…”

Traditionally, digestate is considered a waste, which is used as fertiliser in the agriculture industry. Recent studies focus on increasing the profitability of digestate by extracting reusable nutrients to promote biogas plants cost-effectiveness, sustainable management and circular economy. This review focuses on the post-treatment and valorization of liquor which is produced by solid–liquid fractioning of digestate. Nutrient recovery and removal from liquor are possible through mechanical, physicochemical and biological procedures. The processes discussed involve complex procedures that differ in economic value, feasibility, legislative restrictions and performance. The parameters that should be considered to employ these techniques are influenced by liquor characteristics, topography, climate conditions and available resources. These are key parameters to keep in mind during designing and manufacturing a biogas plant. In the following chapters, a discussion on available liquor treatment methods takes place. The present study examines the critical aspects of the available liquor treatment methods.

“…A potential disadvantage of using digestate in packed columns is that the suspended particulate matter in the digestate can cause fouling on the packing material which, in turn, decreases the effective area available for mass transfer [70]. Ammonia recovery of up to 80% was demonstrated when dairy manure digestate was stripped in a packed column [53].…”

“…This configuration greatly increases the contact area between the liquid and gaseous phases, leading to increased mass transfer. Ammonia removal greater than 91% was reported when stripping with the liquid fraction of anaerobically digested piggery wastewater at pH 11 [70], [75]. Limoli et al [66] investigated the application of turbulent mixing to strip out ammonia from a mixture of cow, pig and poultry manure digestate.…”
