Anaerobic-aerobic Treatment of Dairy Wastewater with National
A short term solution for the treatment of dairy waste water is discussed. Discharge rate'is 500 m3lday with a high organic load (2,750 Kg CODlday). Low capital investment (US $ 330,000) and operational (US$ 0.55lm3) costs were required which ought to be competitive with current market prices but within the official environmental norms imposed by the national agency SEDESOL. The problem was sol...
متن کاملPurification and further characterization of co-lipase from porcine pancreas.
Co-lipase has been purified from porcine pancreas by a method involving tile following steps: acid extraction of pancreas homogenate, heat treatment, (NH4)2SO 4 fractionation, t reatment with ethanol, chromatography on SP-Sephadex, chromatography on DEAE-cellulose and filtration through Sephadex G-75. The method can be applied on a relatively large preparative scale. Starting from 5oo g of panc...
متن کاملDirect asymmetric aldol reactions catalyzed by lipase from porcine pancreas.
Porcine pancreas lipase type II (PPL II) exhibited unnatural catalytic activity in direct asymmetric aldol reactions between cyclic ketones and aromatic or heteroaromatic aldehydes in acetonitrile in the presence of phosphate buffer. A wide range of substrates was accepted by the enzyme to afford the corresponding aldol products in low to high yields (10-98%), with moderate to excellent enantio...
متن کاملMass balance-based plant-wide wastewater treatment plant models – Part 1: Biodegradability of wastewater organics under anaerobic conditions
From an experimental and theoretical investigation of the continuity of wastewater organic chemical oxygen demand (COD) and nitrogen (N) compounds along the link connecting the primary settling tank (PST) and anaerobic digester (AD), it was found that the primary sludge (PS) characteristics, viz. the biodegradable and unbiodegradable soluble and particulate COD and N component concentrations, n...
