ECONOMICAL METHODS FOR PERFORMING OXIDATIVE

Alkaline pre-extraction of biomass was performed at 10% NaOH loading on biomass (w/w based on the dry weight of the biomass) at 10% (w/v) solid consistency at either 90° C. or 120° C. for 1 hr. For the alkaline pre-extraction at 90° C. 100 g (dry basis) of hybrid poplar 950 mL deionized water and 50 mL 5 M NaOH were mixed and placed into ...

Process Design Manual: Nitrogen Control

Wuan and others have shown that the endogenous oxygen consumption rate with nitrate as the electron donor is about one-half of that using oxygen; so in actual practice the solids destruction rate of 0.02-0.1 g VSS/g MLVSS/d would normally correspond to observed rates of about 0.005-0.03 g NOa-N reduced/g MLVSS/d.

History - Babcock & Wilcox

Pre-war boiler production averaged two to three boilers a week; at the end of the shipbuilding program B&W produced about 30 boilers a week. In total 4100 of the 5400 major vessels constructed for the war effort were equipped with B&W boilers. Marine boilers dominated the war years but B&W also forged ahead in research and development.
