Exploring the use of Cactus and Neem Leaf Powder as an Alternative Coagulant in Treatment of Wastewater

Abstract

Opuntia and Neem leaf is a natural based bio-coagulation that can be utilized in bio-coagulation process of kitchen used water collected from the college (MKCE). Opuntia (prickly pear) and neem tree leaf (Azadirachta indicia) powder are used as a Bio-coagulant. Jar test was conducted and the treated samples were evaluated for pH, turbidity, hardness. The dosage of the Bio-coagulant utilized in jar apparatus is 0.2 to 1 g/L for both neem leaf and opuntia powder. The dosage for the Bio-coagulant solution utilized is 5 to 25mL/L. When the Bio-coagulant are utilized directly turbidity was reduced to 50%. When Bio-coagulant are partially utilized with alum the efficiency is about 95% for neemleaf powder and 96% for opuntia powder. So the process reduces the consumption of chemical to 50%. Opuntia and neem could be utilized as an effective natural Bio-coagulant since it costs less when compared with chemical coagulant.

Feasibility Study on Removal of Contaminants using Organic Adsorbents from Industrial Waste Water

“…It is an age-old form of Ayurvedic therapy. Neem oil and Neem leaves are the most common forms [6]. It has properties like anti-bacterial and antifungal effects.…”

OpuntiaFiber and Its Potential to Obtain Sustainable Materials in the Composites Field: A Review

“…Cladodes have also been used to improve dough toughness, adhesion, adherence and hardness (Ayadi et al 2009) of different foods such as bread (Msaddak et al 2017) and cookies (Msaddak et al 2016). Moreover, cladodes have been evaluated as biocoagulants to treat water turbidity (Rubini, Balamurugan, and Shunmugapriya 2019) and as raw materials for bioethanol production (Yang et al 2015). Mucilage has also been examined for water treatment (Adjeroud et al 2018;Ibarra-Rodríguez et al 2017), although it is mainly used in food, pharmacy and cosmetic industries (Sepúlveda et al 2007).…”
