Without sufficient treatment wastewater impacts natural sources of fresh water, an essential resource for food production. With water scarcity becoming ever more prevalent globally, safeguarding fresh water sources is increasingly important.
Government entities may restrict water usage and demand ever cleaner effluent, while consumers are increasingly aware of the environmental impact of the products they buy and food producers themselves start to experience difficulty finding the water they need to produce their products.
When facing these challenges it is good to know that you have a partner in Colubris to address them efficiently.
Meat & poultry processing plants generate a mix of different waste waters, most plants treat the resulting mixture, assuming that combined end-of-pipe treatment will result in the lowest total investment cost.
This industry differs from other meat processors primarily in the amounts of blood and fat in the water. These are either exceptionally high or low depending on the species that is processed and if they arrive alive.
Depending on the type of production, for example milk, cheese, milk powder, yoghurt, butter, etc., the characteristics of wastewater from dairy processing operations can vary significantly.
Thanks to the clean(ed) nature of the ingredients used in this industry, the water usage and pollution generation is comparatively limited.
Sedimentable and dissolved pollutants are the main constituents of potato processing wastewater. Sedimentable solids like sand/clay, starch from washing, peeling, cutting operations.
Water is used for washing, cleaning, sometime cutting, safely transport the products, blanching, heating and chilling.
Water is used for to wash, clean, sometimes cut, safely transport the products and to transport heat away and to the products.
Unlike popular belief this “dry” industry does generate wastewater, mostly from cleaning the equipment. Some of the pollutants in the wastewater are problematic such as fats, starches, flour and yeasts.
Extreme levels of nitrogen compared to carbon often in hot water with a high pH yet high in fat, makes wastewater treatment in this industry particularly difficult, which few companies master.
Alcohol production generates exceptionally high strength wastewater, vinasse, which contains high levels of some of the most difficult to decompose non-biodegradable pollutants generated by an agro industry.
Bottling plants generate a mixture of CIP wastewater complemented by occasional product spillage and sometimes failed batches and store returns.
