Coagulant technologies have historically been part of Nalco Water’s core technologies to achieve fine particle fixation throughout the papermaking process, which include solutions from inorganic to polymeric materials, including Nalco Water’s NALKAT and ULTRION chemistries. In addition to being a key component of the retention and drainage program, other applications include dye fixation, pitch and stickies control, coated broke treatment and alkaline size promotion.
