Abstract

Se describe un método para la limpieza de la superficie de una membrana de RO o NF obstruida o con costras con una solucion que contiene uno o más polímeros termosensibles. Más específicamente, el método comprende: tratar la superficie de membrana incluida en una disposicion de separacion por membranas con una solucion que contiene uno o más TRP, donde dicho TRP es soluble en dicha solucion y por lo menos una cantidad efectiva de dicho TRP se difunde por una capa de suciedad obstructiva depositada sobre dicha superficie de la membrana, hacer que dicho TRP difundido en dicha capa de suciedad obstructiva sea insoluble y, optativamente, enjuagar la membrana.
