The document summarizes research on treating poultry litter leachate using an integrated biological and ozone treatment system. The researcher collected leachate samples and treated them biologically using activated sludge process, then subjected the samples to pre- and post-ozonation at varying pH levels and times. Both the biological treatment and ozonation improved removal of color and chemical oxygen demand (COD) from the leachate. The integrated treatment approach was found to be more effective and cost efficient at removing contaminants than ozonation alone. An optimal pH of 9 was determined for treating the leachate using the combined biological and ozone process.

Proposed Pathways for the Reduction of a Reactive Azo Dye and kinetic reactio...Eleazar Maximo Escamilla
Azo dye degradation from textile effluents has been the objective of research for several years due to the increasingly pollution problem that they generate. For the removal of these compounds, it has been applied different kind of process, since the physicochemical to biological, and has been degraded in diverse reactors. However, is a continuous search for an efficient, low cost and environmental impact to eliminate this problem. This presentation shows one part of the contribution to development a new process for treat waste water from textile industries that present an ecological problem.

Significant efforts are required to abate NH3 emissions from livestock operations. In addition, the costs of fertilizers have rapidly increased in recent years, especially nitrogen fertilizer such as anhydrous ammonia which is made from natural gas. Thus, new technologies for abatement of ammonia emissions in livestock operations are being focused on N recovery. This presentation shows a novel system that uses gas-permeable membranes to capture and recover ammonia from liquid manure, reducing ammonia emissions from livestock operations, and recovering concentrated liquid nitrogen that could be sold as fertilizer.

Excessive emissions of ammonia (NH3 ) from animal manure negatively impact the environment with potential to pollute air, soil and water, and produce malodors. The objective of this study was to assess NH3 mitigation from liquid dairy manure (LM) using tubular acid-filled gas-permeable membranes (GPM) in laboratory experiments; and, to evaluate the possibility of scaling up the NH3 mitigation system for use on AFOs.

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

5. AIM OF RESEARCH:
The aim of present study was to
treat the poultry litter leachate by
integrated system of biological and
ozone treatment to evaluate the
efficiency of these treatments.
14. Results
•Both color and COD removal were increased
continuously with increasing ozonation.
•Reaction pH also influences on the performance
of the ozonation process
color
COLOR:
•Color removal for ASP treated ozonated
sample at pH 5, 7 and 9 were 22, 12 and 53
percent respectively. An optimal color removal
was obtained at 9 pH after 54 minutes
ozonation
15. continued
•For 54 minutes ozonation time, the color
removal at pH 5, 7, 9 and for original pH of the
raw ozonated sample was 29, 46, 29 and 40
percent respectively. An optimal color removal
of 46 percent at pH 7 is evident at 54 minutes
ozone exposure.

Constant increase was Observed
23. Conclusions
Ozonation of raw poultry leachate
sample showed greater color removal
than COD with increasing ozonation
time. Sample pH also influenced the
performance of ozonation. In this
case, optimal pH appeared to be 9 for
COD and 7 for color.
24. Continued….
Post ozonation of ASP treated wastewater
resulted in color and COD removal with
increasing ozonation bubbling time. Varied
pH influence the treatment to a great
extend.
Maximum color and COD removal was obtained
at 54 min ozone contact time at 5, 7 and 9 pH
for raw and ASP ozonated samples.
25. Continued….
Among varied pH maximum COD
and color removal was obtained at 9
pH for raw and ASP ozonated
samples due to production of
hydroxyl radicals at elevated pH.
Electrical energy comparison
demonstrated that Integrated
approach is more cost effective and
feasible option than AOPs alone
26. According to the results, it can be
concluded that integrated treatment
(biological and ozone) are more
effective in COD and color removal
than ozone alone.
27. RECOMMENDATIONS
Best cost effective treatment option for
poultry leachate sample is the integration of
biological and ozone rather than ozone alone.
Recommended optimum pH is 9 for
integrated treatment of poultry leachate
sample which should be kept in consideration
because above pH 9 decrease in COD and
color removal takes place
