What is the advantages and disadvantages of High-Rate Anaerobic WWTP?

Because of its capacity to properly separate hydraulic and solid retention durations, high-rate anaerobic treatment has emerged as a viable alternative for the treatment of many industrial and municipal wastewaters. Because significant biomass concentrations may be stored in the system, high-rate anaerobic treatment systems can tolerate relatively short hydraulic retention durations.

Advantages of high-rate anaerobic treatment systems

1: The challenge for anaerobic technology is to extend the applicability of anaerobic treatment to lower wastewaters, such as sewage and residential effluent.Because anaerobic techniques need less initial investment and require less maintenance than standard aerobic processes, and produce less sludge, direct sewage treatment is unquestionably an appealing and acceptable option, particularly for poor nations.

2: These technologies are intriguing because to the possibility of anaerobic process applications in both centralized and decentralized forms. When anaerobic operations are carried out in a decentralized manner, the investment costs of sewage systems are greatly reduced. Both primary and biological sludge from aerobic treatment facilities must be stabilized before they may be reused or disposed of.On the other hand, one of the primary advantages of anaerobic reactors over aerobic systems is the minimal creation of stabilized (non-putrescible) sludge.

3: Furthermore, usable sludge can be stored in an unfed state. Anaerobic sewage treatment is advocated, particularly in tropical locations, because anaerobic procedures allow for much cheaper treatment costs due to their capacity to function at low temperatures (10-20°C).

4: The reactors may be operated even under psychrophilic conditions if a practical process design is adopted and the organisms are acclimatized to desirable temperatures, and the adaptation of biomass permits the accomplishment of a high treatment capacity in the anaerobic process.

Disadvantages of high-rate anaerobic treatment systems

1: The feasibility of psychrophilic high-rate anaerobic treatment systems for cold wastewater is primarily determined by the quality of the seed sludge used and its development under psychrophilic conditions, the nature of organic pollutants in the wastewater, and reactor configurations, particularly their capacity to retain viable sludge.

2: Although the development of psychrophilic high-rate anaerobic treatment systems has undeniably had a significant economic and ecological impact, there is some reluctance to adopt anaerobic processes, particularly in centralized treatment facilities used for municipal wastewater treatment.

3: Because anaerobic sewage treatment has enormous potential, particularly in touristic areas where seasonal treatment is necessary, significant variations in flay-rate and organic loading rate can be detected when the population grows drastically during the high season. Significant fluctuations in residential wastewater flow and composition over time and from one location to another may degrade process performance in tourist regions since the intensity of the effect is determined by the kind, amount, length, and frequency of the imposed variations. Extreme transient situations in operational parameters might cause the reactor's performance to decrease.

4: The sluggish growth rate of anaerobic bacteria needs extensive reactor detention durations. Long detention durations are claimed to be overcome by sophisticated reactor designs, such as fixed-bed and fluidized-bed reactors, or upflow anaerobic sludge blanket reactor technologies. However, because of the low biogas generation rates, these sludge bed reactors are less easily mixed at low operating temperatures.
