ocess yarn are the key area in the textile industry sector. These substances are used to seal the yarns, in orderto protect them against the mechanical stress of the weaving process. In this way, they enable high weaving speeds. Following the weaving process, the auxiliary has to be removed from the fabric before further processing (bleaching, dyeing, printing) and thus ends up in the waste water. Sizing agents are responsible for up to 8 Yo of the total COD load in the waste water of the textile finishing industry and are, in part, not biodegradable. Thus, an annual COD load of 2,0 to 2,0 results. The global of the research projects was to develop process by which the sinzing waste water could be purified and the sizing agent recovered at the same time. The results showed that ultrafiltration is suitable for the recovery of sinzing agents. The concentrates obtained in this manner could be reused without impaining the weaving process. In addition, no difficulties arose in the subsequent finishing processes. Furthermore, the separated water could also be reused. Recovery of 8 to 8 Yo of the sizing agent (based on the amount of sizing agent used) is possible with the newly developed process. Within the framework of joint project in Egypt on the recovery and reuse of starch sizes in textile mills, it was successfully demonstrated that sizing agents can be effectively recovered by means of ultrafiltration membranes. pilot plant forthis purpose was installed and put into operation at the textile company in Egypt.The results obtained will make an important contribution to the reduction of pollutants in the River Nile. The environmental contamination caused by the leather industry has led to intensive support in this sector. The production of leather, which, as natural product, is used in various products, is primarily carried out in the batch-type process steps of liming, deliming, pickling and chrome tanning. During this process, the skins ar
