SYSTEM SPECIFICATION

When textiles are processed in alkali solution, using the hydrolytic denudation of alkali on textiles, the cloth receives a silky shine, soft touch, and produces alkali deweighting wastewater. The characteristics of alkali deweighting wastewater are high pH, high COD, main pollutants are sodium terephthalate, which is hard to be biodegraded. There are various wastewater quality and quantity with different process and technology.

TA is an important material in producing polyester and plasticizer, but tradition technology produce poor purity and less value to recycle. Implementing KS-C purification device, with acid precipitation to recycle the TA within the alkali deweighting wastewater, a 99% TA can be obtained, which has high recycling value, while decrease more than 65% pollution load, to relieve the environmental burden of further wastewater treatment.

DEVICE SPECIFICATION

Black liquor is quite toxic to aquatic life, and causes a very dark caramel color in the water. It contribute 90% or above COD and BOD of the total emission in the pulp and paper industry. Black liquor has become a critical problem to solve in industries in the case of resource utilization and standard discharge at the same time.

As of now, there are three main ways to separate alkali lignin from black liquor: 1) Acid precipitation method, which by decreasing the pH of black liquor, making the alkali lignin unable to dissolve in the black liquor, settle, or separate; 2) Flocculation, which is mainly the addition of electrolyte into the black liquor（ i.e. PAC/ aluminium polychlorid), to breach the balance of lignin colloid, making it settle. In this way, lignin is dicult for reuse, and can only be incinerated; 3）Membrane separation, using KS-BL recycling system, using physical method to realize lignin separation, obtain by-product to produce all kinds of lignin chemical products easily, which is a leading clean production technology, excellent prospects.
