Team 504 Apollo: Dialysate Water Filter Project

We are working towards reducing water waste in the process of hemodialysis

About Us

The objective of this project is to reduce the quantity of waste-water in the dialysis process by efficiently purifying standardized filtered water and spent dialysate to ultra-pure water. To achieve this we will be utilizing carbon nanotube (CNT) membranes and a Reverse Osmosis system.

Handle a maximum flow rate of 1000mL per minute
Purify water to a Total Dissolved Solids (TDS) measure of less than 0 ppm
Recycle sent dialysate at an efficiency of 75%

CNTs are microscopic tubes of carbon that can be used to capture or adsorb contaminants like metals and minerals from water. They have been used in other fields such as electronics, medicine delivery, and space materials research. The image shown gives an idea of what our buckypaper filter looks like as well as the full system responsible for runnning the water through the filter. The second picture shows a vertically aligned CNT buckypaper.

The video below shows the normal operation of the full system.
