We are innovative tech aggregator  

for dairy waste and wastewater treatment


Why upflow


upflow is a global technology aggregator for cow manure and dairy farm effluent (DFE) treatment solutions.

The significant amount of cow manure and DFE emitted by the global milk production industry is a heavy burden on the environment, causing pollution of water resources, land degradation and greenhouse gases emissions (GHG).

Farm owners are forced to treat cow manure and DFE with diverse incentives, in accordance with their state requirements, herd size and economic vision. Finally, they end up confused due to their lack of expertise in connecting their unique problem with the variety of solutions available in the market. The results are increased expenses and often the purchase of an unreliable, low quality and unsuitable solution for their needs.

upflow provides the farm owner with a high quality, cost efficient end-to-end solution from a wide range of in-house and external modular technologies.

What our clients say

"Two years ago, Rotem and Udi, two hard-working engineers from the Technion, approached me with the aim of developing a first-of-its-kind sewage treatment facility in my dairy farm. The guys seemed like real professionals to me, I congratulated them on the success and recommended them that the cost of the facility shuld be adjusted to the financial status of the average dairy farm. "Today, after many development efforts, I can say that they have met the task and I highly recommend it to all members of the dairy industry."

Giora Harag, manager of the Harag dairy farm in Kfar Hasidim

"Like any dairy farm manager, I want to focus more on milk production and less on farm wastewater treatment. Ever since Upflow came into the picture I have a peace of mind. They take care of the sewage system professionally, support us in dealing with the authorities, and in the bottom line save the farm a lot of money that would have been dumped into the sewer."

Udi Tetz, director of the Yehuda dairy farm

"We started working with Upflow in order to regulate and improve the sewage system in the dairy farm, and save on the high billing costs for the sewage treatment plant. In the effluent charges. "
