Water quality index (WQI) is a valuable arithmetic tool that depicts the overall status of water in single number to prioritize for management interventions. This study aims assess based on WQI provide insights into aquatic ecosystems Marshyangdi River basin, tributary Narayani River, originating from Himalaya. samples were collected twenty-one sampling locations covering four districts upstrea...
Fourier transform infrared (FTIR) imaging is a powerful tool for the assessment of bone quality; however, it requires the preparation of thin bone sections. Conventional poly(methyl methacrylate) (PMMA) embedding for the preparation of sections takes more than two weeks and causes denaturation of the bone. Development of a quick and easy sample preparation technique without denaturation is need...
This study was aimed to determine the spatial variation in anthropogenic pressure exerted on surface water in the Podhale region (southern Poland), which is one of the most popular tourist destinations in Poland. The assessment was based on the dynamics and relationships between microbiological and chemical indicators of water quality throughout the major rivers of this region-Dunajec, Czarny D...
The reverse osmosis (RO) brine generated from the Al-Quds University wastewater treatment plant was treated using an epuvalisation system. The advanced integrated wastewater treatment plant included an activated sludge unit, two consecutive ultrafiltration (UF) membrane filters (20 kD and 100 kD cutoffs) followed by an activated carbon filter and a reverse osmosis membrane. The epuvalisation sy...
A pyrrhotite and sulfur-circulating packed bed reactor (PS-CPBR) was constructed to study the removal process mechanism of NO3−-N PO43−-P with different electron donors. The results showed that performance mixed donors (pyrrhotite sulfur) superior single donor (pyrrhotite). optimum conditions in PS-CPBR were a hydraulic retention time (HRT) 12 h C/N 0, average efficiency 100% 86.39%. sulfur abl...
The present study was undertaken in a constructed wetland (CW), setup tourism house, for domestic wastewater treatment. influence of season variations on the abundance fecal indicator organisms (total coliforms and Escherichia coli) substrate roots plants inhabiting inlet outlet zones CW evaluated along three consecutive years. structure diversity bacterial communities associated to CW’s also a...
The electrolysis method for synthesizing hydroxyapatite nanoparticles (NPs) has the advantage of controlling particle size by adjusting potential and current used. This study aims to NPs formation its characteristics. solution contained Na2H2EDTA.2H2O, KH2PO4, CaCl2, with an EDTA/PO43-/Ca2+ concentration 0.2/0.2/0.2 M. electrolytic are 4, 5, 6 volts hours. carbon electrode spacing used is 2 cm....
This worked assessed the potential of alginate-like exopolymers (ALE) hydrogels recovered from aerobic granular sludge (AGS) in removing compounds commonly present municipal wastewater. Batch sorption experiments were performed with ALE at different operating conditions. Results showed that can only remove phosphate, removal efficiencies up to 90.8% and practical loadings 1.22 ± 0.07 mg PO43?-P...
BACKGROUND Dairy effluents contains high organic load and unscrupulous discharge of these effluents into aquatic bodies is a matter of serious concern besides deteriorating their water quality. Whilst physico-chemical treatment is the common mode of treatment, immobilized microalgae can be potentially employed to treat high organic content which offer numerous benefits along with waste water tr...
