The aim of the study was to assess leaching Cl?, SO42?, and PO43? from ashes formed in household furnaces. were obtained following combustion conventional fuels, namely wood hard coal, alternative fuels with various fractions municipal waste a boiler. Aqueous leachates used determine concentrations chlorides by titration (Mohr’s method) (21.3–3049.6 mg/dm3), sulphates gravimetric method (12.2–2...

Results from different research suggest that metallic iron (Fe0) materials enhance anaerobic digestion (AD) systems to remove organics (chemical oxygen demand (COD)), phosphorus and nitrogen polluted water. However, the available results are difficult compare because they derived experimental conditions. This characterises effects of Fe0 type dosage in AD simultaneously COD nutrients (orthophos...

Surface water sources play an important role in human and biological activities the socio-economic development of region. Therefore, assessment quality determination causes pollution Sao river is essential for good management surface environment. The study was conducted from July to December 2020. Water samples were collected at time low tide evaluate indicators temperature, pH, conductivity (E...

Hydrochemical assessment of the freshwater lakes provides important insights into sources dissolved ions, geochemical processes, and anthropogenic activities taking place in environment. This study focuses on hydrochemistry water quality Kupinde Lake, Karnali Province, Nepal. Surface samples were collected from 24 different locations lake October 2021 analyzed for 18 physico-chemical parameters...

Wetland soils derive their chemical composition from the sedimentary rock underneath. Among metals produced are trace and nutrient elements which facilitate plant growth. Bush burning near mangrove forest is a common practice that has not been given much attention despite its negative impact on environment. We thus hypothesize application of fire wetland soil will negatively chemistry. collecte...

Coagulation can effectively recover substances from wastewater; however, there is a lack of efficient coagulants for simultaneous recovery organic matter, nitrogen, and phosphorus. We prepared composite polysilicate metal (CSM) flocculant by combining Fe3+ Mg2+ ions in polysilicic acid (PSiA). According to the results scanning electron microscopy (SEM), X-ray diffraction (XRD), Fourier-transfor...

BACKGROUND Cr(VI) in aqueous solution is a serious concern that can harm human health by accumulating the food chain. Meanwhile, most common form of waste (FW) disposal landfill takes up lot area and pollutes environment. As consequence, FW was employed as raw material production waste-derived biochar (FWB), which then modified to produce Ce/Fe3O4/FWB composite for high-efficiency removal RESUL...

This study was carried out to understand how land use patterns influence surface water quality in Tien Giang Province using remote sensing and statistical approaches. Surface data were collected at 34 locations with the frequency of four times (March, June, September, November) 2019. Water parameters used analysis, including pH, temperature, electrical conductivity (EC), total suspended solids ...

Constructed wetlands are commonly used to treat domestic wastewater, but the extent which microplastics retained in constructed and impact this has on their efficiency not known. In context, we investigated retention of (microbeads fibres) effects removal carbonaceous (expressed as chemical oxygen demand (COD), biochemical (BOD5), dissolved organic carbon (DOC)), nitrogenous (N-NH4+, N-NO3-, N-...
