Wastewater Treatment in Agriculture

Wastewater originating from agricultural processes is usually not contaminated with mineral elements, but instead primarily with significant loads of organic substances such as starches, sugar or cellulose. DAS Environmental Expert offers a wide range of processes to effectively and economically clean differently contaminated wastewater from animal husbandry, dairy cattle sheds or fruit and vegetable production.

DAS Technologies for Water Treatment in Agriculture

Wastewater occurs at various stations on a farm. The areas of application include, above all, the cleaning of equipment and stables, as well as the cleaning of harvested products. A particularity is the treatment of silage leachate. To prevent contamination of the surface water by this highly polluted wastewater coming from silage production and storage,

it must be separately collected and treated. Our DAS technologies are flexible and can be combined according to your demand — together we identify the best solution for your requirements and wastewater specifics.

Flexible Wastewater Treatment for Agricultural Enterprises

Depending on the focus of the farms, differently polluted wastewater is produced in agriculture and must be treated before re-introduction into the cycle. If livestock are kept, large amounts of water accumulate when cleaning stables, milking equipment or milking parlors. Pig slurry, for example, can be fermented in suitable biogas plants. The resulting biomethane can be used to generate heat and power for the farm’s own needs. The digestate is used instead of liquid manure as organic fertilizer on the farm land.

Silage leachate can also cause problems on some farms. It may also drip onto transport infrastructure during transport. These residues may mix with rain or melt water and significantly contaminate surface waters. Silage leachate should be contained and purified due to its high content of organic substances.

In the plant production sector, wastewater is produced primarily where products are cleaned and processed. As an example, today it is common to wash potatoes before bagging. Vegetables or fruit, such as apples, are also often washed before being packaged for sale. This results in wastewater, which requires treatment. Water is also essential for fruit harvesting and processing. As an example, up to five cubic metres of water are required to process one ton of potatoes. To reduce costs, water in many agricultural processing plants is increasingly recirculated in a loop. Impurities are expelled, and the water is reprocessed for reuse.

DAS Environmental Expert GmbH offers its customers a wide range of processes suitable for purifying agricultural wastewater. These solutions should be a good match for the customer’s operations while effectively and efficiently purifying the wastewater produced, all while taking up as little space as possible.
