    Combined effects of treated domestic wastewater, fly ash, and calcium nitrite toward concrete sustainability by Abushanab, Abdelrahman

    Published 2021
    “…OPC paste and mortar with TWW were first prepared and compared with the permissible limits specified in ASTM C1602/C1602M ? 18 provisions. After that, ten concrete mixes were prepared with different ratios of TWW (0%, 25%, 50%, and 100%), FA (0%, 20%, and 35%), and CN (0% and 3%) and tested for fresh slump and density, compressive and flexural strengths, electrical resistivity, porosity, and chloride permeability. …”

    Enhancing the production of biogas through anaerobic co-digestion of agricultural waste and chemical pre-treatments by Almomani F.

    Published 2020
    “…The results revealed that the highest cumulative methane production (CMP) of 297.99 NL/kgVS can be generated by co-digestion of ASWs and CD at a ratio of 60:40. Further improvement was achieved via alkalinity treatment with 1.0 g of NaHCO3/gVS leading to decrease in lignin, cellulose, and hemicellulose contents of feedstock by 3.5%, 10.5% and 15.9%, respectively, converting them to soluble fractions and improving the CMP by 11.2–29.7% based on substrate quality. …”
