Combined ozonation and adsorption system for the removal of heavy metals from municipal wastewater: effect of COD removal

  title={Combined ozonation and adsorption system for the removal of heavy metals from municipal wastewater: effect of COD removal},
  author={Amir Ikhlaq and Tooba Aslam and Abdul Mannan Zafar and Farhan Javed and Hafiz Muhammad Shahzad Munir},
Heavy metals like copper, chromium, cadmium, lead, and zinc are key contaminants of freshwater reservoirs because of their deadly, non-biodegradable, and persistent nature. The work involves the comparison of various single and combined processes such as ozonation (Ozo), adsorption on activated carbon (AC), adsorption on rice husk (RH), ozonation in the presence of rice husk (Ozo/RH) and ozonation in the presence of activated carbon (Ozo/AC) for the removal of chemical oxygen demand (COD) and…

Synergistically Improved Catalytic Ozonation Process Using Iron-Loaded Activated Carbons for the Removal of Arsenic in Drinking Water

This research attempts to find a new approach for the removal of arsenic (As) from drinking water by developing a novel solution. To the author’s knowledge, iron-loaded activated carbons (Fe-AC) have

Catalytic Ozonation Combined with Conventional Treatment Technologies for the Recycling of Automobile Service Station Wastewater

The ample increase in water scarcity and depletion of natural resources due to their overconsumption and the contamination of water sources becomes more challenging day by day. This challenging

Adsorption of murexide dye from aqueous solution using a novel Schiff base tin(IV) compound

In this study, the synthesis of an easily synthesized, non-toxic and inexpensive material and its use in dye removal have been demonstrated. The synthesis of novel material, tin(IV) chelate compound,

Treatment of methylene blue in aqueous solution by electrocoagulation/micro-crystalline cellulosic adsorption combined process

The continuous application and consequent discharge of dyes from a variety of industries cause severe ecological outcomes. The research reports the treatment of a vastly applied textile dye methylene



Adsorption in combination with ozonation for the treatment of textile waste water: a critical review

Intrusion of synthetic textile dyes in the ecosystem has been recognized as a serious issue worldwide. The effluents generated from textiles contain large amount of recalcitrant unfixed dyes which
