Desalting

The process of desalting of a proline modelling solution by electrodialysis in five- and six-chamber electrodialysis apparatus was investigated. It has been shown that the process effectively proceeded in the six-chamber device. Changes of dry substances and pH of the proline modeling solution and a

Most of chemical reactions have — as a final result — a large mixture of end products out of which the main one represents a small rate when compared with secondary products. One of these reactions results in a mixture of products that takes place in the process obtaining ethylene amines. The reacti

Increasing water shortage in Egypt approaches an alarming level. Treatment and reuse of secondary water sources (comprising brackish water and wastewater) is of current national and international concern. The Egyptian Academy of Scientific Research and Technology (ASRT) allocates considerable fundin

Ultrafiltration (UF) of gelatin liquor from marine source (tuna skins) has been performed on a tubular mineral membrane of cut-off 10,000 Da. An attempt was made to concentrate the fish gelatin as well as to purify it by means of the diafiltration technique (DF). Primary experiments were devoted to
