Development of Cost Functions for Biological Treatment by Membrane Bio-Reactor
Water and Wastewater Treatment
One of the space-saving and alternative options for wastewater treatment is the use of Membrane Bio-Reactor. This paper delineates the sequential approach to explore integrated cost functions for estimation of the forecast level cost for biological treatment of wastewater by use of Membrane Bio...
AN EXPERIMENTAL STUDY ON CONTINUOS REMOVAL OF CHROMIUM (VI+) IONS FROM WASTEWATER EFFLUENT BY USING FLUIDIZED BED REACTOR
Water and Wastewater Treatment
Hazardous metal chromium is used extensively in many different industrial processes and is commonly found in industrial effluents. Hazardous pollutants such inorganic anions, metal ions, synthetic xenobiotics, and others have contaminated ground and surface waters in India and other parts of the...
Utilization of brown seaweed adsorbent for effective removal of Pb(II) from wastewater: Biosorption and column studies
Water and Wastewater Treatment
Researchers have been focusing on protecting water quality and preventing environmental contamination caused by industrial discharge of heavy metals. Various methods have been explored for extracting these metals from wastewater, but they often prove to be costly and rely on non-renewable resources...
Integrating Circular Economy, SBTI, Digital LCA, and ESG Benchmarks for Sustainable Textile Dyeing: A Critical Review of Industrial Textile Practices
Circular economy
Dyes play a crucial role in various industries, but their environmental impact and potential health risks have raised concerns. This review paper examines the classification and applications of dyes, highlighting the challenges posed by synthetic dyes and the growing interest in natural dyes. The...
Impact of biochar on anaerobic digestion of piggery wastewater: Methane production, performance stability and microbial community structure
Water and Wastewater Treatment
Anaerobic digestion of piggery wastewater mediated with biochar was investigated by COD removal rate, methane yield, process stability and microbial community analysis. The results showed that biochar could effectively improve the COD removal rate and methane yield. Compared with blank group, COD...
PROPERTIES OF BIOCOMPOSITES FROM WASTE EGGSHELL AS FILLERS
Solid Waste Management
In recent years there has been a heightened concentration on the industrial subsectors that are the primary contributors to environmental pollution. Filler materials made from mineral limestone, which is composed of calcium carbonate (CaCO3), are utilized in the production of polymer composites in...
Electricity production by Ochrobactrum-related strain CD-1 and pb2+ removal in dual-chamber microbial fuel cell
Soil and groundwater contamination and remediation
Dual-chamber microbial fuel cell (MFC) was constructed to treat heavy metal wastewater (Pb2+ solution). The results showed the maximum voltage, the maximum electric power density and pb2+ removal were 9.6 mV, 371.0 mV/m2 and 52.3% respectively. The effects of different cathode chamber environments...
Effect Of Phytoremediation On The Geotechnical Properties Of Heavy Metal Contaminated Soil
Soil and groundwater contamination and remediation
The accumulation of heavy metals in soils increases rapidly due to various natural processes. Heavy metal pollution changes the geotechnical properties of soil and poses a serious threat to human health and ecosystems, so soil pollution remediation is particularly important. Phytoremediation is an...
Experimenting the Various Behavior of Pumpkin Seed Oil Methyl Ester with Varied Injection Pressure – Combustion and its emission performance
Air Quality
Because of its better physio-chemical qualities, biofuel is indeed a viable substitute source of energy for diesel vehicles. The biofuels used in this study is synthesized from pumpkin seed oil using the esterification reaction technique. The biodiesel was synthesized under ideal conditions and was...
Research on the removal of pollutants from water environment by lanthanum modified montmorillonite
Water and Wastewater Treatment
The management of water pollution has been one of the main problems as people pay more and more attention in the current society to the preservation and repair of the natural environment. In this paper, natural montmorillonite was modified with starch as well as lanthanum chloride. The removal...
