Abstract
Indicators of water consumption and the quantity of wastewater formed in selected branches of food industry The studies covered the branches: sugar industry, fruit-and-vegetable processing and potato processing plants. The analyses of water consumption and quantities of wastewater formed in 24 production plants were performed in the paper. A comparison of water and wastewater management in three branches showed that the highest water consumption is in fruit-and-vegetable processing. The data collected in the paper indicates the drop of water consumption in potato as well as fruit-and-vegetable industry. The values obtained for sugar industry indicate that it is the least diversified branch.
Highlights
Due to its entry into the European Union, Poland had to undertake several tasks associated with the adaptation to legislative requirements of the Community
The purpose of the task was to determine the indicators of water consumption and the amount of wastewater formed in fruit-and-vegetable processing plants, in plants recasting potato and in sugar factories
The sugar factories are characterized by the one-way production profile (1 main product – sugar), whereas fruit-and-vegetable processing plants and potato processing plants (PPP) are the plants of diversified product range
Summary
Due to its entry into the European Union, Poland had to undertake several tasks associated with the adaptation to legislative requirements of the Community In Poland, the main branches of economy utilizing fresh water resources include: chemical as well as farm and food industry. In the latter, in the branch of fruit-and-vegetable processing, very high pressure is put on economic management of water since it is the medium utilized in very large quantities and the specifics of the production cause creation of large quantities of wastewater. In the processing of fruits and vegetables (including potatoes) as well as in the process of sugar production, over 22% of water was drawn in this branch. The purpose of the task was to determine the indicators of water consumption and the amount of wastewater formed in fruit-and-vegetable processing plants, in plants recasting potato and in sugar factories
