Characteristics of raw wastewater: The pond system
treats approximately 4500 m3/d of wastewater from
starch and approximately 500 m3/d of wastewater from
glucose factory. A scheme of anaerobic ponds and
sampling points is shown in Fig. 3. The characterization
of raw, influent and effluent wastewater of the pond
systems is shown in Table 2. The wastewater characteristics
at sampling point, ‘a’ and ‘d’, in Table 2 corresponds,
respectively to raw wastewater from starch
and glucose factory.
