| Abstract | This study was conducted in a medium size of block rubber and latex concentrate
processing factory in Daklak province, Vietnam. The maximum production capacity is
1,576 tons block rubber and 166 tons latex concentrate a month. The company produces
excellent quality product for in country uses and exportation. At present, on the low period,
block rubber is produced around 31 tons a day and no latex for latex concentrate process.
The water usage in the production process originates from treated wastewater. The water
consumption is so high approximate 1,322 m3 per day.
Currently, the existing wastewater treatment plant was not efficiency. A study was
conducted in order to solve the problems by waste minimization in the rubber production
process and improve operation of the treatment plant. The wastewater generations of 912.6
m3
/d in the block rubber process and 205.9 m
3
/d in latex concentrate process are combined
and sent to the effluent treatment plant.
Modification was urgently needed, and it was done by resizing dimension of wastewater
treatment ponds. Results from wastewater treatment study indicated that interpond
recirculation should be used and modify the rubber trap, the anaerobic ponds, and the
aerated ponds system. Furthermore, waste minimization at source is proposed by waste
segregation method. The wastewater streams are proposed to segregate based on SS
concentration. A bench rock filter is suggested for reused pretreated wastewater in
production process. |
