Sofi Filtration

Innovation in Industrial Water Filtration

Presentation by Simo Aho

Need

Problem

• Large water streams with fine particle contaminations need to be treated

• Difficult to handle with traditional methods like settling

Macroeconomic drivers

• Tightening environmental regulations

• Water cost and scarcity

Sofi technology for recirculating process water

• Less fresh water intake

• Less environmental impact

• Pure water in process

• No valuables to waste
