Dr. Krofta began to design and manufacture equipment for wastewater treatment for the paper industry. His improvements in hydraulic design resulted in major improvements in DAF technology performances in water clarification, with lower chemicals and energy consumption. The high efficiency of equipment like the Krofta Supracell allowed for high rate of pulp recovery and reuse of process water, reaching the goal of zero discharge for a water demanding industry. Milos Krofta started several branches in the world. His contribution to technological improvement in the use of dissolved air flotation is so significant that the equipment itself is often called "The Krofta".
