Mix & Match Customization with Programmable Pores. Not only can the membranes be customized to produce the desired product water, these membranes can also be customized to other characteristics of your feedstock water. As well as producing high purity water, the goal is reduce or eliminate pre-treatments, post-treatments and maintenance requirements.

The membrane is built by assembling components to give the desired performance. It is the standard automobile assembly process, but on the atomic scale: pick your model, pick your exterior finish, and pick your interior package.

How customizing your membrane works:
1. Define your desired product water. Then choose the best pore from the Pore Library.
2. Test your feedstock. Using a specially designed testing disk, test your feedstock to determine the best surface chemistries to prevent fouling and scaling.
3. Are additional capabilities needed? Can we engineer in a solution at the atomic scale?

CASE STUDY: POINT SOURCE AGRICULTURAL WATER CLEANUP
The rising importance of wastewater remediation is driven by the need to reclaim wastewater for drinking purposes, use in agriculture without developing toxic levels of chemicals in both soil and food, and the concern about discharging a range of injurious chemicals into the environment. We are now working with a water district interested in remediating 50,000 Acre Feet per year of agricultural runoff coming directly off of farmers’ fields. For this project, we would select the Urea Exclusion Pore. In addition to removing the full range of chemicals from pesticides, fungicides, and fertilizers - including phosphates and nitrates, residual arsenic and other groundwater contaminants - this pore removes urea, found in agricultural runoff from fertilizer use, animal waste, natural composting processes and tilling the soil. Urea contains 90% of the nitrogen in nitrate wastes, and must be removed. This pore is able to defeat urea – which is smaller than the desirable earth salts - while letting the larger earth salts pass, and then excluding larger contaminants. The result is high purity, potable water that is cleaner even than water treated with Reverse Osmosis and ultraviolet. To determine the best surface chemistries, we would test over multiple months to observe seasonal variations.

This project is focused on generating a new source of water in a water-parched part of the United States. If it were used in the Baltic Sea, on rivers leading into the Mediterranean, in the United States adjoining the Great Lakes or the Chesapeake Bay, this same pore would be used to stop the build up of nutrients that lead to algae blooms and eutrophication.
