Nitrogen-fixing bacteria (NFB) can reduce nitrogen at ambient pressure and temperature. In this study, we treated effluent from a paper mill in sequencing batch reactors (SBRs) monitored the abundance activity of NFB with view to producing sludge that could work as biofertilizer. Four were inoculated activated enriched fed high C/N waste (100:0.5) mill. Though able organic load wastewater by up...

The present research shows the results obtained from biosorption process of Pb, using coffee pulp as a biosorbent in synthetic waters. To do this, lignin and cellulose content percentage removal Pb2+ ions was determined; additionally, sorption’s optimal variables, such optimum pH, point zero charge (pHpzc), kinetics adsorption isotherm, were determined. A comparison made with other by-products ...

There is a lack of information on the extent mineral extraction by plants from wastewater in arid and semi-arid environments developing countries. This research assesses performance Alhagi Mallow plant species for absorption heavy metals around tailings dam copper mine Iran. The industrial , known as pulp, site has different concentrations metals. In laboratory setting were cultivated irrigated...
