Performance of Natural Coagulants on Greywater Treatment

Abstract: Background: Reusing waste water by appropriate treatment is an effective method for substantiating the ever increasing water demand for construction, irrigation, domestic and industrial purposes. The greywater is the domestic waste water that does not contain the toilet effluent and it is converted and used for non-potable purpose through coagulation and flocculation by using natural coagulant. Objective: The main objective of this work is to evaluate the coagulating efficiencies of various natural coagulant… Show more

“…These values agree with those presented by Chitra & Muruganandam [36] and Al-Gheethi et al [42] with a range removal from 83.3-85.7%. Water-soluble cationic proteins from MO seed extracts that enhance coagulation and flocculation.…”

“…Several authors have proposed the use of MO as a natural coagulant in greywater; for example, Chitra & Muruganandam [36] used dehydrated seeds and evaluated the removal of turbidity in synthetic (85.6 NTU) and real (92.7 NTU) greywater, where they found efficiencies of 85.3% in synthetic and 83.7% in real greywater and higher efficiency in pH between 6 and 7. On the other hand, Rodriguez et al [37] used dehydrated seeds to evaluate the removal of turbidity in greywater (73.2-99.1 NTU) from washing machines, from the experiments performed, they found removals of 96.22% with optimum pH between 6.8 and 7.2.…”

“…[1] In this view, novel approaches continue to be emerging across the world to achieve a sustainable management of domestic/municipal effluents. [4,5] To date, various biological and physico-chemical approaches have been successfully applied for the treatment of domestic and municipal effluents. [6,7] Among these, the biological systems such as septic tank, anaerobic and aerobic filter, and other attached growth reactors, etc., have been reported to be appreciably successful (having efficiency above 80%) in urban societies.…”

“…According to Vigneshwaran et al (2020), the widespread use of aluminum-based chemical coagulants causes a variety of neurological problems, whereas bio-coagulants have natural properties that make them toxic to aquatic life. Different researchers studied natural coagulant such as microbial polysaccharides (Saleem and Bachmann, 2019), bio-wastes (Atchudan et al, 2020), gelatin, cellulose-based materials (Leite et al, 2017), chitosan (Agbovi and Wilson, 2019), Moringa oleifera (Rocha et al, 2020), Moringa oil (Chitra and Muruganandam, 2019). Natural coagulants are commonly used in less developed populations as a point-of-use product, as they are fairly cost-effective compared to chemical coagulants.…”
