We show the cost of chlorine in the case of caustic credits from export and domestic business (Figs 1.8 and 1.9). It is one of the many paradoxes in the business that although the plant is built for the chlorine, for most of the time the profit comes from the caustic soda. (Figure 1.10 shows the origin of the chlorine in the derivative trade.) The management of the caustic return is vital to the industry. The cyclicality in the demand for caustic with the supply will continue though the number of players in the business will probably reduce. 

Design considerations in the joint treatment of dairy and domestic wastewaters are the high chlorine demand and the presence of surface-active agents. In addition, cheese production wastewaters are usually nitrogen deficient. Septicity should be a consideration in the design of any equalization or clarification facilities. 

Increasing demands on the performance of detergents have led to the use of enzymes in detergent formulations destined for both domestic and commercial applications. To a degree, enzymes can take the place of chlorine bleach and phosphates, both of which can have detrimental environmental consequences. Lipases and ceUulases are the most useful enzymes for detergent applications.
