the computer simulation program of a practical scale reverse electrodialysis process has been developed based on the program for saline water electrodialysis. the program is applied to compute the performance of an industrial-scale reverse electrodialysis stack (effective membrane area s = 1 m × 1 m = 1 m2, cell pair number n = 300 pairs). the stack operatingconditions are optimized. seawater a...

Considering the complexity of hydrological processes, it seems that multivariate methods may enhance the accuracy of time series models and the results obtained from them by taking more influential factors into account. Indeed, the results of multivariate models can improve the results of description, modeling, and prediction of different parameters by involving other influential factors. In th...

Multidielectric polyethylene is a material that is generally employed as insulation for  the HVDC isolations. In this paper, the influence of temperature on space charge dynamics has been studied, low-density polyethylene (LDPE) and Fluorinated Ethylene Propylene (FEP) sandwiched between two electrodes were subjected to voltage application of 5kV (14.3 kV/mm) for extended duration of time ...

The study carried out to evaluate some of the physical and chemical properties ground water samples from west Alshirqat district, Salaheddin province, IRAQ. Six wells selected, sample collected every month for 6 months (October,2021 – March 2022). In each electric conductivity (EC), pH, total dissolved solid (TDS), oxygen (DO), biological demand (BOD), hardness (TH), calcium (Ca H), magnesium (...

The physicochemical qualities of a typical rural-based river were assessed over a 12-month period from August 2010 to July 2011 spanning the spring, summer, autumn and winter seasons. Water samples were collected from six sampling sites along Tyume River and analysed for total nitrogen, orthophosphate, biochemical oxygen demand (BOD), temperature, pH, dissolved oxygen (DO), electrical conductiv...
