The textile industry has experienced significant advances accompanied by the production of large volumes polluted water released into environment, which requires treatment that varies according to nature pollutants. present work aimed at testing 13X type zeolites synthesized from Djebel Debagh DD1, DD2, and DD3 kaolins in order remove dyes other pollutants effluent COTITEX (Batna, Algeria). Sev...

Hydroxyapatite (Ca10(PO4)6(OH)2, HAp) is a calcium phosphate-based biomaterial that widely used in bone implants due to its similarity composition with the constituent elements of bone. However, HAp still has poor mechanical properties, so research was carried out improve properties such as reduced brittleness, less fracture resistance, and denser structure by synthesizing composites PEG. This ...

The microalgal-bacterial granular sludge (MBGS) process is expected to meet the future requirements of municipal wastewater treatment technology for decontamination, energy consumption, carbon emission and resource recovery. However, little research on performance MBGS in outdoor was reported. This study investigated system treating under natural alternate day night conditions late autumn. resu...

This research aims to determine the structure of phytoplankton community in waters Cikidang River, which can use as a bioindicator water quality. The began November 2021-February 2022 using survey method. Sampling does at four stations. determination stations by considering land and river orders. parameters analyzed are transparency, temperature, Salinity, pH, Carbon Dioxide (CO2), Biochemical ...

After the change of communist regime and takeover agricultural areas by private permits, they, in context presence on market a limited range chemical fertilizers at low prices, began their irrational application, order to obtain large yields. Although most farmers currently apply fertilizer resources scientific basis, effect previous practices is still felt, affecting groundwater quality. This ...

In this study, we investigated ways by which to optimize metals and nutrients solubilization from sewage sludge using alkaline–thermal hydrolysis the Box–Behnken design. We also examined through struvite crystallization recovery of solubilized hydrolyzed liquid determined effect NaOH concentration, liquid/solid ratio, temperature on process. Nutrients was positively affected decreasing liquid/s...

Abstract The purpose of this research was to evaluate the potential plant-immobilized bacterial cells synergism for enhanced remediation polluted river water. water sample collected from Kalyani river, Uttarakhand, India and characterized by high concentration COD (1010 mg/l), BOD (230 NO3−-N (30 PO43−-P (48.9 Pb (1.028 mg/l). This treated on a lab scale with immobilized Epipremnum aureum in va...

Abstract. Physical-chemical parameters of the Akor River were investigated. The river water was sampled for seven months (February August) in 2019 and analysed following standard procedures protocols. results revealed that there no significant differences (P > 0.05) among all investigated physical-chemical across stations. Mean values within Federal Ministry Environment set standards (2011) ...

Study of the ground water quality in Hodeidah is an essential ingredient for a healthypopulation. In this research, study of drinking water samples for eight water sources wells in theQuti field has been achieved. The purpose was to a certain the quality of water from thesesources, the physical properties such as pH, electrical conductivity (EC) and total dissolvedsolids (TDS), showed the varia...
