Abstract: Reactive magenta dye (RMD) has been removed from the aqueous solution by different coagulants such as natural coagulants Moringaoleifera (MO), Strychnos potatotrum (SP), and Alum chemical coagulants (AC) respectively. All these three coagulants were studied with various parameters to optimize the maximum removal %, like coagulant dosage from 10 ml to 60 ml, RMD concentration range of 100 mg/L to 500 mg/L, contact time between 10 min to 60 min, and pH kept neutral. The maximum percentage removal was achieved by SP coagulant at 60 min contact time, 100 mg/L dye concentration, and 60 ml coagulant dosage whereas MO and Alum achieved the maximum of 93% and 85% respectively. The results showed that MO seeds, SP seeds, and AC coagulants performed well in the removal of suspended solids and dye color. Furthermore, this research validated the preparation of low-cost eco-friendly coagulants and effective jar test methods for treating reactive dyes which are present in real textile water.
