Jan. 2018, SafBon invited several experts of China's papermaking industry to visit its European subsidiaries, including KWI France and KWI Austrian factories. During this visit, they were arranged to visit the paper mill of Kimberly Clark Corporation in NANCY. An MCH 80 type high efficiency air flotation equipment was installed in this factory in 2008. It was developed independently by KWI. As an equipment, which integrating advanced air flotation technologies, has a removal rate of 20-25% higher than that of KWI's competitors and covers only 1/5 of the traditional air floatation devices . This equipment has a processing capacity of 1000m3/h and its SS in effluent is less than 10mg/L. It is mainly used to treat the wastewater, which is called white water, in papermaking process.

The owner introduced that the equipment had been running stably with no spare parts damaged or replaced for over 20 years since it was put into operation. The SS in the treated white water can always meet the requirements of the ultra-clear white water standard. And it can be used as spray water in the papermaking process. With this recycle water, it is estimated that 3 to 3.5 tons of clean water will be saved per ton of paper. The air flotation surface sludge layer has a uniform thickness and the sludge concentration reaches 5%.

Kimberly Clark Corporation is a global leader in health care field. It has established plants in 35 countries around the world with an annual production value of US$18 billion. KWI mainly provides air floatation technology for such high-end customers in the paper industry to solve the problems of fiber recycling and wastewater treatment.

As the inventor of air flotation theory, KWI currently has 12 types of air floatation equipment covering all areas of industrial water treatment. It has more than 70 years of engineering experience in the field of papermaking water treatment, and currently has more than 7,000 engineering cases in the world. The U-type sloping plate air flotation equipment is specifically developed for the paper industry. It is equipped with the latest generation of ADR dissolved gas generators to enable the quality of effluent water to reach the water reuse standard. KWI has established a strategic partnership with Kimberly Clark as a supplier of innovative technologies. Since 1989, the cooperation between the two sides has reached 31 projects.

Through this visiting, everyone has a new understanding of KWI, the air flotation originator. This experience may make the experts recognize what can be called excellent air flotation technology when the air floatation market is mixed and increase their confidence when choosing KWI products in technical design.
