A Jurisprudential Study of the Theory of Connection and Mixing in the Treatment of Polluted Water

Increasing population and rapid industrialization and declining quality of water resources around the world have placed limitations on water use. Therefore, one of the solutions to fix this problem is the use of unconventional water and wastewater treatment and its use in various applications of drinking, agriculture, and health. Despite the fact that this issue has been studied in detail from a technical and engineering point of view, but unfortunately from a jurisprudential point of view, the method of purifying polluted water from wastewater has not been dealt with. One of the important issues that jurists have dealt with in the matter of the method of purification of polluted waters is whether the treated wastewater is purified after the decay of the three attributes (smell, taste, and flavor) as soon as it is connected to the Asem waters (water which is considered inherently pure, and therefore may be used to purify oneself.) or not. There are two main views on this in jurisprudence. Some believe in the theory of connection and others believe that connection is not enough and mixing is a condition in addition to connection. In this paper, by explaining the jurisprudential background of the subject, the jurisprudential arguments of those who believe in the two theories of connection and mixing have been examined and Mukhtar's point of view has been explained in this regard. In this paper, Mukhtar believes in the theory of connection and the most important reason for proving this theory is Ibn Bazi's narrative from Imam Reza.
