THPS mainly was used as a biological(Sewage treatment agent) whose chief advantage is that it quickly degrades into a completely harmless substance after being used and therefore it’s widely used in water treatment, oil and paper making industries, which greatly reduces the industry's impact on the environment. In addition, it also can be used as permanent flame retardant for cotton and polyester-cotton fabric.
