Many nations are seeing an increase in water pollution from dairy and cheese production due to the high organic and fat content in their waste products and the high temperature of their waste products, which elevates the water temperature and causes loss to ecosystem components. Reusing industrial wastewater that has been treated to guarantee no harm has been done to the environment is being hampered by a lack of water. This study compares the presence and absence of mixing in the anaerobic biological treatment of liquid waste for the cheese industry. To decrease heat exchange with the external environment, cube-shaped anaerobic reactors with dimensions of (30 x 30 x 30) cm and thick glass (10 mm) were utilized in this investigation. The temperature of the two reactors was 35°C, with the first reactor containing a mixture and the second reactor containing no mixture. Samples were obtained every five days and evaluated in the laboratory to monitor changes in the characteristics of liquid cheese waste during the treatment period, which was 30 days. The indicators (pH, EC, TDS, TSS, COD, and Alkalinity) were used, and a total of 72 tests were performed throughout the research period for each indicator. The results appeared that the first anaerobic reactor with the combination removed 95.1 % COD, whereas the second reactor that did not contain the mixture removed 94.1 % COD. The anaerobic reactors are very efficient in treating COD; the COD removal rate in the first reactor with the combination was 1.9 %, while the COD removal rate in the second reactor without mixing was 94.1 %. The increase in pH in the first and second reactors, followed by achieving the neutralization value, is proof of anaerobic reactor success. Total dissolved solids removal was achieved in anaerobic reactors in the first reactor (7.5 %) and peaked in the second reactor (17.83). The proportion of TSS removed in the first anaerobic reactor was 57.9%, and in the second reactor, it was 60.3 %. From all above can be concluded that the presence of mixing had a slight and negligible positive effect on the anaerobic reactors Keywords. Mixture, Liquid Waste, Cheese Industry, Anaerobic reactors.
This research deals with the concept of space in the theatrical performance and how the director works between two different spaces, the closed space and the open space. The question was how to use space according to the director's vision in the presentation. The problem of the research was whether the director of the Iraqi filmmaker could see the variable in the architectural space Or the place or space within the exhibition between open and closed, through the formation of the vision of the external components of intellectual and aesthetic and aesthetic, and impact on the relationship between the actor and the recipient to produce a new aesthetic space, and then the purpose of research and importance and limits and terminology The seco

The subject pronoun is one of these topics that should be considered. Due to the uniqueness of this pronoun among the rest of the family of pronouns, with features and adverbs that deserve research and study, and then analysis and treatment; Because of its scientific value, it goes hand in hand with other pronouns. This topic would not have drawn my attention or received much of it had it not raised some fundamental questions, including, f

This study include two branchs: First: isolation and identification of Bacillus stearothermophilus from soil, 5 sample were collected from the soil of the college agriculture/Baghdad university. Samples were cultured on nutrient agar, microscopic and culturing tests were conducted and many biochemical tests were done. The isolates were cultivated at 55 c and 65 c for differentiate it from Bacillus coagulans which is can't grow at 65 co. The c

The research is based on the hypothesis that the monetary policy of Iraq contributes to achieving financial stability, which improves economic sustainability by providing aid and assistance to the state to reduce the budget deficit and exacerbate indebtedness. The author used the monetary policy indicators, the re-deduction of Treasury transfers by the central bank and the money supply, and financial sustainability indicators, including the public debt indicators and the

This study was conducted in Animal Resources Department , College of Agriculture to estimate the effect of chemical and biological treatments to improve the nutritive value of poor quality roughages ( corn cobs and wild reed ) . The feeds were treated chemically with 4% NaoH solution ,whereas Aspergillus niger was used to ferment corn cobs and wild reed samples . The chemical analysis showed that protein percentages of corn cobs and wild reed was increased significantly (P<0.05) from 6.05% to 10.51% and 17.70% and from 3.10 %to 6.50% and 9.96% for both chemical and biological treatments respectively. The crude fiber percentages decreased significantly (P<0.05) from 29.19% and 26.10% to 23.60% and 20.10% for chemical treatment and was 20
