This paper presents a literature review of the quality of greywater generated in different, especially developing, countries, constituents found in greywater, some treatment systems, natural materials for treatment, some reuse strategies and public perception regarding greywater reuse. The review shows that generation rates are mostly influenced by lifestyle, types of fixtures used and climatic conditions. Contaminants found in greywater are largely associated with the type of detergent used and influenced by other household practices. Many of the treatment systems reviewed were unable to provide total treatment as each system has its unique strength in removing a group of targeted pollutants. The review revealed that some naturally occurring materials such as , sawdust, can be used to remove targeted pollutants in greywater. The study further showed that user perceptions towards greywater treatment and reuse were only favourable towards non-potable purposes, mostly due to perceived contamination or lack of trust in the level of treatment offered by the treatment system.
本文对不同国家，尤其是发展中国家产生的中水水质、中水所含成分、一些处理系统、用于处理的天然材料、一些回用策略以及公众对中水回用的看法进行了文献综述。综述表明，中水产生率主要受生活方式、所用洁具类型和气候条件的影响。中水所含污染物在很大程度上与所用洗涤剂类型相关，并受其他家庭习惯的影响。所综述的许多处理系统无法提供全面处理，因为每个系统在去除一组目标污染物方面都有其独特优势。综述显示，一些天然材料，如锯末，可用于去除中水中的目标污染物。研究还表明，用户对中水的处理和回用仅对非饮用水用途持赞成态度，这主要是由于他们认为中水受到污染，或者对处理系统提供的处理水平缺乏信任。
