Abstract
A detailed beverage effluent treatment technology was developed in a period of 4 months, using
samples from an operating beverage plant. The total number of samples collected were 1304. The volume of the
sample collected hourly was 500ml for 4 hours to give a composite sample. The plant operated continuously for
6 days a week and had two-12 hour shifts a day. The technology consisted of four water treatment methods
combined consecutively which were chemical, physical, biological and physical treatment methods. The aim of
developing the technology was to reduce the sCOD, TSS and pH parameters to the required environmental
specification. The untreated beverage wastewater has high solids content, high organic matter, and low pH
which need pretreatment before it is discharged into the municipal sewage treatment works. The developed
technology reduced the high solid content, high organic load and adjusted the pH to the required Bulawayo
Municipality environmental specifications. The average percentage reduction in sCOD and TSS was 91.1% and
90.6% respectively. The pH was adjusted to 8.05. The obtained results indicated that the developed technology
was effective for treating beverage wastewater at ambient temperature to meet the quality of effluent that can be
discharged into public water works.
