Conception and sizing of an industrial waste water treatment station equipped with biogas digester, UV reactor and reverse osmosis unit

Abstract

The reuse of the treated waste water in all fields (agricultural, industrial, domestic) is an orientation asked by all intervening parties in the water sector in the purpose to protect the environment and combat the scarcity of water resources. This valorization cannot be done without making the appropriate treatment in order to respect the norms. In this work, we are developing a general method to conceptualize a treatment station equipped with biogas digester, UV reactor and Reverse Osmosis (RO) unit. The modeling approach developed permits to test and to ameliorate the efficiency of each cited technique. The main basic equations used are those of Maxwell, mass transfer, radiation transfer and energetic transfer. We have made an analytical resolution of those equations and we have expressed the necessaries formulas for the design of each technique. Results from case studies were presented.
