Abstract

Paint manufacturing industries have many unfavorable
environmental impacts such as freshwater consumption. Especially, paint
industry wastewater treatment plants consume huge water volumes. Water
footprint is described as the total volume of water required for a concept. The main aim of the study
is to determine the seasonal variation of water footprint for a full-scale
paint industry wastewater treatment plant which locates in Turkey. Grey water
footprint was evaluated by Water Footprint Network methodology. Chemical Oxygen
Demand (COD), Total Suspended Solids (TSS) and Oil and Grease (O&G) are the
pollutant parameters to detect it. Water consumption of the plant contains
sludge treatment, process water usage and other residential activities are
defined as the component of blue water footprint. According to the results,
maximum grey water footprint was measured in May as the value of 2455.840352 m³.month^-1.
The least total grey water footprint is related to August as 536.7118464 m³.month^-1. Total blue water footprint
is 4866.9 m³.year^-1 and the peak value is 421.7 m³.month^-1
in March.  According to the study, the
grey water footprint is higher than blue footprint. The results reveal that for
decreasing water footprint, COD removal efficiency should be increased and
wastewater reuse alternatives should be implemented.
