Haşlama Et Atıksuyunun Membran Biyoreaktör (MBR) Sisteminde Arıtımı

Abstract

The demand of food products have increased by the same proportion in parallel to the rise of population in the World and in our country.
This has made the food industry, one of the world 's largest industrial sector. During the production of the food industry, it produces large
amounts of solid and liquid waste. So that, the negative effects on the environment of waste water resulting from the various food industry
has also increased. Production of meat and meat products which are one of the main foods of people consume have increased too. So the use
of water have been increasing too. The water which is used in these industries are given back to the receiving environment as contaminated
with various pollutants. Because of the production type of each industry, the differences of production technology and amount of production,
the characteristics of the waste water varies. Therefore, in determining the treatment technology and expression of the options must be
handled separately for each industry. Existing technologies, most of the time in the provision of wastewater discharge limits are in adequate.
So, the alternatives of new treatments need to be take into account. In this study, the treatment of ¼ and 1/10 of a percent of diluted boiled
meat wastewater belongs to the food industry in the Bilecik Organized Industrial Zone were carried out in Lab/Pilot Scale Membrane
Bioreactor (MBR) System. Active sludge which was used in MBR system have gotten from Bilecik I. Organized Industrial Zone biological
treatment pool. The temperature of the aeration tank was controlled at 20 ± 1 °C, the pH value and the concentration of dissolved oxygen
(DO) was kept respectively, in the range of (6,0-8,0) and 6-9 mg/L in the aeration tank. Samples were taken for analysis from wastewater
tank, aeration tank and permeate outlet. COD, phosphate and nitrogen concentration value were measured daily in influent as well as effluent
to assess the removal efficiency. As result of first series experimental study, the removal efficiency of COD, phosphate and nitrogen was
determined as %77,2; %92,7 and %91, respectively. In the second series experimental study conducted the COD removal efficiency was
determined as 83.8 % with a dilution ratio of 1/10.
