Algunos aspectos sobre la contaminación debida a la tintura de poliéster a alta temperatura.

Martí Crespi Rosell, Mª Simó Sanahuja

Resum


The biodegradability of two dispersing agents and a levelling agent used in high temperature dyeing of polyester is studied in this paper. The analytical methods used are also mentioned.
Depuration in an activated sludge pilot plant of two effluents made with the products studied is also considered as well as the influence on the depuration rate exerted by the biodegradability of the above products.
