Our research aims to study how to use dried lemon peels and ground moringa in purifying gray water, as well as what is the difference between the properties of the two samples of washing machine water before and after purification in terms of transparency, salinity, acidity and oxygen.
We asked the following questions:
1. How can dried lemon peels and ground moringa be used to purify water?
2. What is the difference between the properties of the two samples in terms of transparency, salinity, acidity, and oxygen?
With increasing interest in environmental sustainability and reuse of water resources, purifying used washing machine water is a major environmental and economic challenge. The research includes studying the use of low-cost, environmentally friendly natural materials such as dried lemon peel and dried and ground moringa leaves in purifying washing machine water. To answer the research questions, we dried the lemon peel and moringa leaves, ground the moringa into a powder in the form of a powder, and placed specific amounts of materials in the purification tool so that the washing machine water could pass through it to evaluate its effectiveness in removing pollutants (oils, detergents). This became clear to us by measuring the acidity, salinity, transparency, and oxygen before and after purification. We concluded that lemon peel has the ability to absorb oils and odors because it contains acidic compounds and aromatic substances. Moringa leaves are also efficient in precipitating fine impurities and suspended materials because they contain proteins that act as natural coagulants.
