Abstract
Nowadays amount of wastewater from agriculture and industry is increasing which puts it to
alarming situation. So, scientists try to come up to alternative solution for treatment that will
minimize wastes. One of them is greener approach, which has benefit of being environmentally
friendly. In this review, three types were considered: bio-coagulation, usage of zeolites and
advanced oxidation processes (AOPs). Bio-coagulation is method of treating water based on
using coagulant agent from plants. Zeolites due to their porous structure can reduce chemicals
in water. AOPs use radicals that then applied to the organic molecules and produce non-toxic
ions. All of the three approaches capable effectively remove pollutants from wastewater and
have their own benefits and drawbacks. It seems that bio-coagulation way is more efficient in
comparison with due to its high performance, low cost, availability and being biodegradable.
