Flue gas desulfurization (FGD) wastewater is characterized by low pH, high content of hardness ions and COD.In this work, chemical precipitation and ultrafiltration (UF) membrane separation were corporately coupled to treat the FGD wastewater on a lab scale to remove the hardness as well as some organic compounds for further advanced treatment.Firs
Learning from Chatting: How Our Virtual Reference Questions Are Giving Us Answers
Objective - This research compares two types of online reference services and attempts to determine whether the same sorts of questions are being asked; which questions are being asked most often; and whether patron and staff behaviour is consistent or different in the two types of online reference sessions.Patron satisfaction with the two types of
Structural optimization of stiffener layout for stiffened plate using hybrid GA
The current trend in shipyard Walkie Talkies industry is to reduce the weight of ships to support the reduction of CO2 emissions.In this study, the stiffened plate was optimized that is used for building most of the ship-structure.Further, this study proposed the hybrid Genetic Algorithm (GA) technique, which combines a genetic algorithm and subseq
A new method to determine the mixing state of light absorbing carbonaceous using the measured aerosol optical properties and number size distributions
In this paper, the mixing state of light absorbing carbonaceous (LAC) was investigated with a two-parameter aerosol optical model and in situ aerosol measurements at a regional site in the North China Plain (NCP).A closure study between the hemispheric backscattering fraction (HBF) measured by an integrating nephelometer and that calculated with a
