Bioavailability of zinc oxide nano particle with fly ash soil for the remediation of metals by .

To investigate the interaction of zinc oxide nanoparticles (ZnO NPs) with fly ash soil (FAS) for the reduction of metals from FAS by were studied. The average accumulation of metals by stem were Fe 79.6%; Zn 88.

Model for bioavailability and metal reduction from soil amended with petroleum wastewater by rye-grass L.

To assess the tolerance, the rye-grass L. grown on soil amended with petroleum wastewater (PWW) containing four metals lead, zinc, nickel and mercury. The PWW (25 to 50%) showed remarkable increase in length and biomass.

Role of calcium oxide in sludge granulation and methanogenesis for the treatment of palm oil mill effluent using UASB reactor.

The granulation process in palm oil mill effluent using calcium oxide-cement kiln dust (CaO-CKD) provides an attractive and cost effective treatment option. In this study the efficiency of CaO-CKD at doses of 1.5-20 g/l was tested in batch experiments and found that 10 g of CaO/l caused the greatest degradation of VFA, butyrate and acetate.

Integrated application of upflow anaerobic sludge blanket reactor for the treatment of wastewaters.

The UASB process among other treatment methods has been recognized as a core method of an advanced technology for environmental protection. This paper highlights the treatment of seven types of wastewaters i.e.
