Study on performance of carbon source released from fruit shells and the effect on biological denitrification in the advanced treatment.
In order to solve the problem of shortage of carbon source for biological denitrification in advanced treatment of the effluent from secondary treatment of sewage, five kinds of fruit shells (pistachio shell, peanut shell, ginkgo shell, walnut shell and hazelnut shell) were preliminarily selected from eight kinds of fruit shells for experiments of static carbon […]
Nanocomposites of zero-valent iron@ biochar derived from agricultural wastes for adsorptive removal of tetracyclines.
Tetracycline antibiotics as the emerging pollutants had been drawn abroad increasing concerns. An agricultural waste, the lignocellulosic hazelnut shell, was used as the carbon source to prepare the nanocomposites of zero-valent iron@biochar by pyrolytic reduction method at 1123 K for 2 h in N2 atmosphere. The adsorptive removal of tetracycline, oxytetracycline and chlortetracycline by the zero-valent […]
High sorption efficiency for As (III) and As (V) from aqueous solutions using novel almond shell biochar.
Arsenic (As) presence in surface reservoirs and groundwater is considered as an extremely alarming issue around the globe. The objectives of the present study were to evaluate the sorption potential of almond shell (ALS) and almond shell biochar (ASB) based sorbents for the removal of As(III)/As(V) from As-contaminated aqueous solutions. The maximum As(III) sorption capacity […]
Electrocoagulation and electrooxidation pre-treatment effect on fungal treatment of pistachio processing wastewater.
The effect of electrochemical pre-treatment on fungal treatment of pistachio processing wastewater (PPW) was investigated. Electrocoagulation (EC) and electrooxidation (EO) were used as electrochemical pre-treatment step before fungal treatment of PPW. Aluminum (Al/Al), iron (Fe/Fe), and stainless steel (SS/SS) electrode pairs were selected as anode/cathode for EC whereas boron doped diamond (BDD/SS) was preferred as […]
