About Us

KWI is a leading solid-liquid separation provider, a company that was directly inherited from the father of DAF, Dr. Milos Krofta. Dr. Milos Krofta brought DAF technology to the world, starting from fiber recovery in paper mills. He evolved DAF into a solid-liquid separator capable of matching the diversifying challenges in the market today. He later received the Five-Star Award from Pollution Engineering Magazine in 1982 as a result of his outstanding achievements.
