Abstract

In this paper an endeavor is made to study the feasibility of natural coagulant like Cassia alata, Calotropis procera, Hyacinth bean, banana leaves, Carcia papaya, Acacia mearnsii, Jatropha curcas cactus, tamarind seeds and watermelon seeds on the decrease of red phosphorous content from industrial wastewater. The batch coagulation test was done to identify the optimum coagulant dosage required for the removal of red phosphorous in the wastewater. A chart was plotted between the removal efficiency of all the chosen coagulants. The removal percentage of red phosphorous is more for hyacinth bean with 75 percent, followed by casuarinas leaves and banana leaves tamarind seed demonstrates the minimum red phosphorous removal from the waste water 56 percent. Hyacinth bean can be utilized as a successful coagulant for the removal of red phosphorous from the wastewater. Percentage removal efficiency of red phosphorous was achieved for the coagulant dosage 20 mL, pH of 8, and initial red phosphorous convergence of 4372.5 mg/lit, mixing time of 30 minutes, settling time of 45 minute and the final red phosphorus concentration of 1072.5 mg/lit.
