2 Algae are fast-growing, photosynthetic microorganisms that absorb nutrients and produce valuable biochemical byproducts... In this presentation a technology is described that utilizes the controlled growth of algae as the driving force for a best management practice
3 Our work focuses on a patented technology, the algal turf scrubber, that has proven to be reliable and effective as a tool for nutrient removal from a waterbody.
4 The algal turf scrubber (ATS) utilizes native algae that grow attached to a screen in a shallow, flowing water system. This technology contrasts with most algal growth systems that utilize suspended algae instead of attached algae. One advantage of the ATS is that attached algae are easier to harvest than suspended algae.
5 Eutrophication in the Chesapeake Bay is associated with out-of-control algal growth. However, the algal turf scrubber technology relies on controlled algal growth!
6 The ATS technology has been implemented at the large scale in Florida and Texas and we are now hoping to scale-up from experimental studies that have been conducted throughout the Chesapeake Bay watershed
7 We envision the algal turf scrubber as the basis of a green economy that cleans polluted water and provides a valuable byproduct that can be used as a feedstock for biofuels or for other useful products.
8 Nutrient removal by the algal turf scrubber is calculated as follows: Nutrient removal rate = biomass production rate x nutrient content of biomass grams nutrient/m2/day grams dry weight/m2/day grams nutrient/grams dry weight Typical biomass production rates range from 5 30 grams dry weight/m2/day and typical nutrient contents are 3-5% nitrogen and % phosphorus.
9 We ve operated experimental algal turf scrubbers all around the bay as noted on the map to the right. Data has been gathered at least over an annual cycle at each of these sites.
10 Walter Mulbry of USDA has operated scrubbers for more than a decade
11 Walter s original work focused on dairy wastewaters.

13 Some of the experimental ATS were small scale. This system was located on the Patuxent River.
14 The small scale systems were one square meter in area
15 Data from the small scale systems was similar to the larger systems.
16 From the spring of 2008 to the fall of 2009 the algal turf scrubber technology was tested at Exelon s Muddy Run hydroelectric facility.
17 Two experimental ATS were constructed and operated at Muddy Run. Each raceway was 300 feet long and 1 foot wide. One raceway had a 2% slope and the other had a 1% slope. These systems were operated from 2008 to 2009.
18 The algal growth in these raceways was studied to gather information for optimizing the design of large scale ATS.
19 To harvest algae, the water flow was stopped and the system was allowed to drain. Then algae was harvested with a shop vac.
20 The productivity of the ATS raceways at Muddy Run was high, compared to natural ecosystems, but algal growth was limited by low temperatures in the winter months.

23 A number of recent studies have been conducted at the Virginia Institute of Marine Science in the lower Bay
24 Data from the VIMS ATS systems indicates higher productivities than found in the more northern portions of the Bay
25 Algal species composition varies along the salinity gradient of the Bay. This species of diatom is common in brackish water but absent in freshwaters.
26 Our largest experimental system is located on Maryland s Eastern Shore in a farm setting. Our challenge here has been to run the pumps on solar power
27 Work on the Eastern Shore has demonstrated harvest techniques at a larger scale than most of our experimental systems
28 We hope the algal turf scrubber represents a new BMP that can compliment the existing conservation tools available to farmers for nutrient removal
