Abstract: Water is one of the most important substances on earth; nowadays, its pollution is one of the main environmental problems. Textile industries pose a significant environmental problem for earth. Firstly, it is due to their huge water consumption, and secondly, they produce a lot of wastewater contaminated with dyes, chemicals, suspended solids, etc. These contaminants can make water unsuitable for the desired purposes (e.g., drinking, watering, washing and showering). The one of the promising methods for the removal of dyes from the contaminated wastewater is adsorption. In this process, we can use low cost waste materials as an adsorbent. This paper presents an overview of utilization of the spent coffee grounds for the removal of dyes from wastewater.
