Article Synopsis
  • - This study investigates the presence of 15 phthalate acid esters (PAEs) in three water sources in YiXing City, with an emphasis on the Jiubin drinking water treatment plant's (JTP) role in managing these contaminants.
  • - The concentrations of total PAEs varied across the water sources, with bis(2-ethylhexyl) phthalate (DEHP) constituting 80% of the total PAE levels, peaking in March 2015, January 2015, and July 2014.
  • - Although the ecosystem risk from these PAEs is considered low, there are still concerns regarding their presence in drinking water, highlighting the need for effective source control and improved

The influence of humic acid (HA) on the removal of arsenic by FeCl was systematically studied in this paper. Jar tests were performed to investigate the influence on arsenic during FeCl coagulation of the pH adjusting method, the initial As/Fe ratio, the equilibrium As concentration, and co-occurring anions and cations. Compared with results in HA-free systems, the removal trends of arsenic in HA solutions were quite different.

The solidification/stabilization (S/S) of chromite ore processing residue (COPR) was performed using zero-valent iron (ZVI) and lime-activated ground granulated blast furnace slag (GGBFS). The degree of Cr immobilization was evaluated using the leaching procedure, mineral composition analysis and morphology analysis. Semi-dynamic leaching tests were implemented to investigate the potential for reusing the final treatment product as a readily available construction material.

A bench scale study was performed to assess the effectiveness of the solidification of chromite ore processing residue (COPR) by blast furnace slag and calcium hydroxide, and investigate the enhancement effect of pre-reduction using zero-valent iron (ZVI) on the solidification treatment. The degree of Cr immobilization was evaluated using the Toxicity Characteristic Leaching Procedure (TCLP) as well as the solid waste-extraction procedure for leaching toxicity-sulfuric acid & nitric acid method (Chinese standard HJ/T299-2007). Strength tests and semi-dynamic leaching tests were implemented to investigate the potential for reusing the final treatment product as a readily available construction material.
