Abstract
The aim of the present work is to study water recycling and reuse in a soft drink
Factory.
Water is an essential raw material in the soft drink productions with a consumption of
2.5 to 3.5 liter of water per liter of soft drink. The wastewater generated in this
industry is mainly from bottle washing, filler backwashing, washing of bottle
machines, equipments, floors and pipe work during flavor changing. The major
contaminants in this effluent are caustic soda and sucrose
In order to reduce water consumption and volume of wastewater generated in the
soft drink plant, Sulave private sector factory was chosen as a case study of the
generated wastewater in the plant .The study was carried out between May till
October 2010 for measuring and monitoring various pollutants of the generated
wastewater in the plant.
Two strategies had been proposed, in the first wastewater out of bottle washing
machine and washing columns could be recycled to the units if treated by: Filtration-
Adsorption-Reverse Osmosis system, this proposal reduced water consumption in the
factory by about 35% and decreased wastewater effluents by 65% of total wastewater
effluents. The second strategy was to reuse water out of the bottle washing machine
after treating it by: Filtration-Adsorption system to be used in the washing column
.The water consumption in this strategy was reduced by about 15% with a reduction
of 35% in wastewater effluents
