What is it about?
A yarn dyed processing industry contains different dyes and pigments in the wastewater. By using combined electrocoagulation and ozonation , the COD removal was 87.4 % using 5.8 % mol ozone at 400 rpm for 60 minutes. The kinetic parameter was also estimated based on the experiment data which resulted in reaction rate constant was 173.5 cm3/(g sec).

Why is it important?
Our findings show that color removal from real yarn dyed wastewater was achieved using electrocoagulation which showed the 92.53 % removal. Ozonation has been able to reduce the COD up to 87.45 %. The optimum condition in ozonation was at 400 rpm and 5.8 % mol of ozone concentration. The kinetic reaction was second order with kinetic constant (k) of the reaction was 173.5 cc/(g sec. This kinetic parameter can be used to design reactor at pilot scale.
Perspectives
I hope this paper will be beneficial for readers who are interested in the study of non-biodegradable wastewater.
