Selection of an AOP and alternatives for water reuse As proposed in section Case Study in a Meat Processing Plant experiments in bench and pilot scale should be carried out before the selection of an AOP for the tertiary treatment of the wastewater intended for reused Sievers 2011 . This initial research would define i the best treatment for each kind of industrial wastewater considering the reused water quality required and hence which improvements should be sought . color or turbidity removal target recalcitrant organic compound removal disinfection ii the kind and quantity of radical scavengers present in the wastewater . humic substances iii the dosage of oxidant if used and the impact of its residual concentration on the subsequent use or disposal of the tertiary treated wastewater and iv the energy and investment costs Sievers 2011 . The tertiary treated water could be used in other processes without contact with food products non-potable uses where public health and product integrity would not be compromised. Therefore this major health concern makes it imperative for governments and the global community to implement proper reuse planning and practices emphasizing public health and environmental protection EPA 2004 . Boiler feed water cooling water toilet flushing water or irrigation around the plant are some alternatives for the use of reclaimed water Cornel et al. 2011 Luiz et al. 2011 . Cooling water may be the most attractive option because it does not need to be of high quality and usually a large amount is required Cornel et al. 2011 . A sentence at EPA 2004 resume the past and the future of wastewater reuse indirect potable reuse Notwithstanding the fact that some proposed high profile indirect potable reuse projects have been defeated in recent years due to public or political opposition to perceived health .
