Product Application

Currently, water treatment equipment exchange system for printing and dyeing industry consists of two exchange columns and one rotary valve specially designed based on alignment principle. Through the periodic rotation and alignment, the autonomous system realizes relative movement and periodic exchange of various liquids for production, regeneration and cleaning; regenerant is supplied automatically by the regeneration system. Two exchange columns work in succession to realize continuous water production.

Printing and dyeing enterprises consume large amount of steam and water. Water quality impacts not only the product quality of pretreatment and other processes, but also on the consumption of dyes and auxiliaries.

Ca, Mg and salt in hard water react with soap and generate indissolvable calcium magnesium soap depositing on fabrics, and generate indissolvable incrustation in alkaline solution which attach on pretreatment equipment and hinder normal production. When iron and manganese content in water exceed the limit, rust will be generated and oxidized cotton fiber will be catalyzed during boiling off. During oxidizing agent bleaching, iron and manganese will also catalyze and decompose bleaches and damage cotton fiber.

Water for boilers must be soft water, otherwise, incrustation will deposit on boiler wall, reducing the conductivity of boiler wall, which will lead to higher fuel consumption and even boiler explosion.
