Present research work deals with the physical and chemical
characteristics of the effluent discharged from the ""Govada Cooperative Sugar Mills Ltd."",
Chodavaram, Visakhapatnam district, Andhra Pradesh, India. The effluents from different zones of
the sugar mill waste are collected. The samples from each zone are taken and the various
parameters like colour, odour, temperature, pH, COD, dissolved oxygen, total dissolved solids and
total hardness of the effluent are determined. The heavy and toxic metals such as mercury, lead,
arsenic, cadmium, etc., which may spoil the aquatic, plants, animals and human bodies are also
measured. It is observed from the plots that the pH, dissolved oxygen and heavy metals like
mercury, lead and arsenic increases from zone 1 to zone 3, also the temperature, COD, total
hardness, total dissolved solids and heavy metals of cadmium and chlorine decreases from zonel to
zone 3.
