Hexavalent chromium is a heavy metal used in a variety of industrial applications which is
highly toxic to humans, animals, plants and microorganisms. Moreover, it is a well …

Chromium is a heavy metal of commercial importance, thus significant amounts are released
in wastewaters. Chromium in wastewaters and in the aquatic environment is primarily …

The anthropogenic inputs of hexavalent chromium [Cr (VI)] have increased enormously
during the past few decades and has become a challenge for life on earth and hence …

The present study was aimed to assess the ability of Bacillus sp. JDM-2-1 and
Staphylococcus capitis to reduce hexavalent chromium into its trivalent form. Bacillus sp …

This paper examined the feasibility of agricultural wastes used as solid carbon sources and
the effect of determined agricultural wastes on improving denitrification. Eight agricultural …

Nickel (N (II)) and cobalt (Co (II)) are often encountered in wastewaters. As conventional
wastewater treatment may only partially remove nickel and cobalt, a large fraction of the …

Heavy metals, such as lead, chromium, cadmium, zinc, copper, and nickel, are important
constituents of most living organisms, as well as many nonliving substances. Some heavy …

Abstract Hexavalent chromium (Cr (VI)) may inhibit denitrification in biological wastewater
treatment systems, and the inhibited denitrification process is difficult to recover in a short …

The effect of hexavalent chromium (Cr (VI)) on extracellular polymeric substances (EPS) of
granular sludge was investigated in an aerobic granular sequencing batch reactor (GSBR) …

In the operation of biological wastewater treatment processes, fast sludge settling during
liquid-solids disengagement is preferred as it affects effluent quality, treatment efficiency and …
