Availability of fresh water is crucial nowadays in many parts of the world. Many natural water bodies are contaminated with chemicals. Phosphate is one among them. The study focuses on removal of phosphate using various herbs like neem, tulsi, rice husk by filtration. There is also a need for introducing a low-cost filter mechanism so as to make this water purification process available to everyone within the society. A lake water sample is also tested to determine the efficiency of the filter.
