Description

As the agency reported it.

However, 15% to 25% of the feed water becomes waste stream, called reverse osmosis concentrate or brine, presenting a disposal issue, especially critical for inland communities. Higher water recovery is limited by membrane scaling due to silica, phosphate, and hardness metals, such as calcium, associated with the brine. The project team has developed a new photobiological process that utilizes the biology of brackish diatoms and natural sunlight to remove these scalants, enables additional freshwater recovery from treated reverse osmosis concentrate using secondary reverse osmosis, reduces the concentrate volume to less than 5%, absorbs carbon dioxide, and produces beneficial algal bioresources. This project seeks to demonstrate continuous pilot photobioreactor operation using sunlight and reduction of the reactor footprint.
