Sirri Island is one of the most important islands in Iran where contains massive amounts of crude oil reservoirs and is a crude oil exporting and storage spot. Petroleum sludge wastes produced by the refineries are deposited in outdoor 2-ha open pits. 30 sludge samples from different depot locations were conducted in 3-time intervals and mixed with each other to form one homogenized sample. The...

Heavy metals contamination can be found at battery acid recycling sites, electroplating facilities, military installations, firing ranges, brownfields redevelopment sites, and associated with mining activities. The chemical stabilization process uses non-hazardous chemical binders that permanently stabilize heavy metals. The treated soils contain stable metalreagent compounds that eliminate the...

Tricalcium silicate (C3S) as clinker minerals was synthesized to investigate the solidification/stabilization (S/S) mechanism of lead, chromium and zinc ions on cement matrix. Effects of various hydration phases on the S/S mechanism were analyzed using XRD, SEM-EDS and heat evolution. Lead, chromium and zinc leachability from solidified hydration phases were also investigated using the toxicity...

Various analyses of physico-chemical characteristics and batch tests were conducted with the sludge obtained from a full-scale electrolysis facility for treating coal mine drainage in order to find the applicability of sludge as a material for removing Zn(II) in an aqueous phase. The physico-chemical analysis results indicated that coal mine drainage sludge (CMDS) had a high specific surface ar...

Steel slag (SS) is one of byproduct steel manufacture industry. The environmental concerns SS may limit their re-use in different applications. goal this study was to investigate the leaching behavior metals from before and after treated by microbially induced carbonate precipitation (MICP). Toxicity characteristic procedure, synthetic procedure water tests were performed evaluate major element...

Bricks manufactured from dried sludge collected from an industrial wastewater treatment plant were investigated. Results of tests indicated that the sludge proportion and the firing temperature were the two key factors determining the brick quality. Increasing the sludge content results in a decrease of brick shrinkage, water absorption, and compressive strength. Results also showed that the br...

Municipal solid waste incinerator fly (IFA) ash is prone to accumulate high concentration heavy metals. Due the increasing costs treat remaining at landfill, a lot of research has been done recycle IFA. This studywas focusing on properties IFA and cement as main raw materials in new inventive blended cement. The were also being investigated. Properties examined through several test which includ...

Biomedical waste is a collection of medical from diverse sources that pose major risk to human, plant, or animal life now in the future. It cannot be processed discarded off without proper processing. often burnt incineration plants, yielding Incinerated Waste Ash (IBMW) which disposed landfills, are not completely leak-proof. The impact IBMW ash as cement replacement on strength and permeabili...

Municipal solid waste incineration fly ash (MSWI FA) consists predominantly of compounds comprising elements such as calcium, aluminum, silicon, sodium, and others. Additionally, it encompasses a complex mixture heavy metals, chlorides, sulfates, organic pollutants, other constituents. The effective economically viable treatment MSWI FA poses formidable challenge for resource cycling at the cur...
