rinsing can be reduced by 50% providing hot water(90 C) is used throughout all rinsing Detergents and complexing agents in rinsing can be left out completely providing good pretreatment and use of soft water for rinsing 12] as also shown earlier in labscale U3). Thus, rinse water characteristics may well be changed, and reclamation of hot rinse water without content of detergents or complexing agents may well be the future goal 3, Water reclamation 3 Chemical precipitation Removal of reactive dyes by precipitation with various precipitants has been shown possible by other researchers(4-7]. On this basis advanand limitations of techniques based on precipitation were sought in labscale and pilotscale, and a number of metal salts and organic polymers were tested. A total of 39 different dyestuffs has been tested in synthetic process waters as well as actual process waters. Organic polymers and PACs have proven most successful. They work in the pH range of 2-10, having the lowest polymer consumption at low pH levels but best nocculation/sedimentation properties at higher pH levels. Temperature optimum for precipitation was found between 20-40°C with decreasing efficiency at higher temperatures, but for some polymers full dye removal could be seen at 70°C. Above this temperature precipitation has its limitations. Increasing temperature and increasing salinity will increase the amount of precipitant needed, and for the high salinities seen in the dye bath precipitation becomes impossible. For the dye bath, and maybe the first rinse, precipitation is thus not realistic(Fig. 2). The mechanism of polymer precipitation is the establishment of an ionic bond to the negatively charged groups of the dyestuff. Adsorption on metal hydroxyl flocs gives only a poor removal, worst for the red dyes, for which, for example, Al(SOA) has no effect at all. Precipitation
