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...

The Gulf of Papagayo at the northern Pacific coast of Costa Rica experiences pronounced seasonal changes in water parameters caused by wind-driven coastal upwelling. While remote sensing and open water sampling already described the physical nature of this upwelling, the spatial and temporal effects on key parameters and processes in the water column have not been investigated yet, although bei...

Renewable energy, water conservation, and environmental protection are the most important challenges today. Osmotic membrane bioreactor (OMBR) is an innovative process showing superior performance in bioenergy production, eliminating contaminants, low fouling tendency. However, salinity build-up main drawback of this process. Identifying microbial community can improve production contaminant tr...

Wastewater causes significant environmental harm. Researchers have created a variety of approaches to address this issue. In study, phytoremediation technology was used remove pollutants from wastewater so that it could be for other purposes. This is one the most promising because inexpensive, ecologically benign, and effective at removing pollutants. Using methodical mapping approach, aquatic ...

Life cycle assessment (LCA) was performed in dairy buffalo farms representative of Southern Italian farming systems, similar due to several characteristics, with the exception wheat production. This work evaluated impacts derived from this management choice, comparing crop (WWC) or not (NWC). In agreement literature, economic allocation chosen as a useful strategy attribute equivalents by-produ...
