Nitrate-removal activity of a biofilm attached to a perlite carrier under continuous aeration conditions. (2/35)

The nitrate-removal activity of a biofilm attached to a perlite carrier from an aerobic bioreactor used for treating dairy farm wastewater was examined by batch experiments under continuous aeration conditions. Despite aeration, the biofilm removed nitrate at a rate of 114.4 mg-N/kg-perlite/h from wastewater containing cow milk and manure. In a clone library analysis of the biofilm, bacteria showing high similarity to the denitrifying bacteria Thauera spp. were detected.  (+info)

Removal of estrogens from water using activated carbon and ozone. (5/35)

Estrogens (estron: E1; estradiol: E2; estriol: E3) are major water pollutants. For the removal of estrogens, activated carbon (AC) and ozone treatments were employed, and the chemical oxygen demand (COD) and pH of a single solution and multiple solution systems were investigated. The removal of estrogens increased with the amount of AC. The percentage of removed estrogens by AC in the single solution system was greater than that in the ternary solution system. The estrogens were completely removed using ozone, which also reduced COD and pH. The removal of estrogens increased the water quality and decreased the amount of organic carbon.  (+info)

Biological Oxygen Demand (BOD) analysis is a laboratory test used to determine the amount of oxygen consumed by microorganisms during the decomposition of organic matter in a sample of water. It is a measure of the pollution potential of a wastewater, with higher BOD values indicating greater pollution. The test involves measuring the difference in dissolved oxygen (DO) levels between a controlled incubation period (usually five days) and the initial DO level. The difference is reported as the BOD, typically expressed in milligrams per liter (mg/L) or parts per million (ppm). This information helps in assessing the effectiveness of wastewater treatment processes and monitoring water quality in rivers, streams, and other bodies of water.
