Perchlorate is not only a known health hazard for human but also one of the persistent inorganic pollutants. Some significant technologies have been carried out to remove or reduce perchlorate in water. A comprehensive review about these technologies is presented, including adsorption, membrane filtration, ion‐exchange (IX), biodegradation, chemical reduction, electrochemical reduction and bioelectrochemistry...
This paper presented the operation results in the full-scale suspended carrier biofilm (SCB) process for the treatment of the low C/N ratio monosodium glutamate wastewater (MSGW). After the long-term operation of 185 days, the removal efficiencies of COD, total nitrogen (TN) and ammonia nitrogen (AN) achieved above 89.5%, 91% and 92.5% at the influent organic loading rate (OLR) of 1.25-1.8 kgCOD/(m...
Ammonium adsorption characteristics of the denitrifying filter and the biologically aerated filter backwashed sludge and influence factors such as sludge concentration, sludge activity and effect of chemical coagulants were investigated. Ammonium was found to be adsorbed to both kinds of backwashed sludge. The backwashed sludge in biologically aerated filter adsorbed more ammonium than that in denitrifying...
