Why wastewater treatment is mandatory for textile and leather industry

INTRODUCTION

APEO are man-made and unnatural chemicals, and therefore, in theory, should be present in wastewater or finished by the deliberate use product.
In some places, however, due to the historical use without restriction, there will be background levels of APEO in the environment. The presence of local background should not be used as an excuse to ease restrictions.
The only way to limit their presence at the basic level is the use of a deliberate policy of non use.
The following actions will limit the presence of APEO in wastewater at the base environment.

What are alkylphenol ethoxylates?

Alkylphenol ethoxylates (APEO) are the product of an industrial process ethoxylates, where nonylphenol (NP) and octylphenol (OP) are treated with ethylene oxide to give nonylphenol ethoxylates (NPEO) and octylphenol ethoxylates (OPEO).

Approximately 90% of APEO used in the textile and leather industry are NPEOs.

What are their uses?

APEO are nonionic surfactants which have several uses in the textile and leather.
They can be found in many preparations, including detergents, emulsifiers, dispersants and lubricants spinning.
They can be found in almost every stage of textile and leather processing.

REASONS FOR ELIMINATION

APEO partially degraded during wastewater treatment , returning to the more toxic OP and NP in particular . NP is very persistent in the environment and do not degrade easily.

NP is known to mimic the hormone estrogen , and is described as a hormone ( endocrine ) disruptive. It is also very toxic to aquatic organisms.

It is therefore essential to remove APEO wastewater process and the final product.

APEO in industrial wastewater will be a persistent pollutant with potentially serious effects on aquatic life and drinking water rights.

Although the greatest risk of exposure is APEO industrial effluents , it is possible that the fabric and clothing can contain residual concentrations of APEO , especially if the treatment plant is wet mismanaged .

It is a condition of the business facilities wet processing providing M & S eliminates APEO production and ensure that they comply with all aspects of standards and ECP RSL .
