    • Characterization of coagulation active agent from moringa oleifera for water turbidity and hardness removal 

      Nurfahasdi, Meutia; Fahmi, Muhammad Ridwan, Dr.; Umi Fazara, Md. Ali, Dr.; Salsuwanda, Selamat (Universiti Malaysia Perlis (UniMAP), 2012-06-18)
      The objective of this study was to explore the capacity of the coagulation active agent that extracted from Moringa oleifera (MO) by various solutions for turbidity and hardness removal in raw water sources. The extracted ...

    • Decolorization and degradation of reactive red 120 azo dye by oxidation processes 

      Che Zulzikrami, Azner Abidin; Fahmi, Muhammad Ridwan, Dr.; Ong, Soon An; Nazerry Rosmady, Rahmat; Siti Nurfatin Nadhirah, Mohd Makhtar (Universiti Malaysia Perlis (UniMAP), 2012-06-18)
      In this study, the treatment of azo dye, Reactive Red 120 (RR120) by oxidation using (ozone) O3 and ozone/hydrogen peroxide (O3/H2O2) treatments were evaluated. O3 carried out using a glass reactor, generated from an ...
