A simple fabrication of a biodegradable membrane for use in water purification systems is presented in this work. Sodium carboxymethyl cellulose and PVP are dissolved in water and crosslinked with citric acid. The presence of glycerol has given immense flexibility and mechanical strength to the membrane. The addition of activated charcoal has enhanced its purification and dye adsorption capabilities at room temperature in dark and light conditions. The polymer semiconductor composites are completely soil degradable within a week and the membrane also exhibits good electrical conductivity when compared to the membrane without charcoal. The addition of glycerol has acted as molecular spacer between polymers composite's monomer backbone that allows good electron mobility of 9.9 cm2 V−1 s−1. The dye adsorption efficiency of the material with two commonly used toxic textile dyes is found to be 100% for methyl orange and up to 57% for Rhodamine B within 3 h. The material shows good dye adsorption efficiency under dark and light conditions with acidic, neutral, and alkaline pH. Salt rejection was also found to increase from 25.3 to 64.4% with applied voltage. © 2019 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2020, 137, 48746.

“…These technologies should be easy to implement and control, cheap in construction and operation costs, highly efficient, environmentally friendly, and implemented on small areas of land with low energy consumption. Several novel technologies meet the previous requirements such as electrochemical oxidation, electro-coagulation EC, electrodialysis ED, photo-electrooxidation, electrochemical disinfection and sterilization, membrane filtration (ultra-filtration, nano-filtration, and reverse osmosis) as well as nano-adsorbents [14][15][16][17][18][19][20][21][22][23]. The integrated and hybrid treatment systems based on these technologies provide an ideal solution for the desired target.…”

Treatment of municipal wastewater using advanced physicochemical process maximizes the removal of biological oxygen demand (BOD 5 ), chemical oxygen demand (COD) and phosphate. Also discarding of suspended solids using nano adsorbent then electrochemical treatment, followed by ultra-filtration membrane was conducted. So, treated wastewater can be reused for agriculture of non-edible or wood trees, fishes, livestock and sheep farming. The results showed that: BOD 5 , COD, and phosphates percent removal of 93%, 95% and 100% respectively. Using mini hydro turbine of power generation about 1.5 k wt/h and with a flow rate of 10-15 L/s. 50% of the energy consumption could be recovered by rotation of the mini hydro-turbine using reject flow. Construction and operating costs of sewage treatment plants can be reduced up to 50% compared with that of traditional low-efficiency biological treatment plants. Sludge produced from the advanced proposed process in this investigation can be used as fertilizer due to its quality while that produced from the traditional treatment process is unsafe to reuse.
