Subject:
sampling; stream flow; water quality; nitrate nitrogen; watersheds; ammonium nitrogen; North Carolina
Abstract:
... The balance between resources expended and information obtained is an integral aspect of water quality investigations. As part of a Water Quality Demonstration Project in the eastern Coastal Plain, we monitored stream water quality at the watershed outlet. Four methods of assessing stream water quality were compared. These methods were time-composite sampling with continuous flow measurements (TC) ...

Subject:
nitrification; ammonia; pH; wastewater treatment; pellets; pig manure
Abstract:
... Nitrification of ammonia (NH 4 + ) is a critical component for improved systems of animal wastewater treatment. One of the most effective processes uses nitrifying microorganisms encapsulated in polymer resins. It is used in Japan in municipal wastewater treatment plants for higher nitrification rates, shorter hydraulic retention times (HRT), and lower aeration treatment cost. We evaluated whether ...

3. Treatment of swine wastewater using a saturated-soil-culture soybean and flooded rice system

Author:
Szogi, A.A.; Hunt, P.G.; Humenik, F.J.
Source:
Transactions of the ASAE 2000 v.43 no.2 pp. 327-335
ISSN:
0001-2351
Subject:
saturated conditions; wastewater treatment; constructed wetlands; pig manure
Abstract:
... Constructed wetlands have potential for treatment of livestock wastewater, but they generally contain wetland plants rather than agronomic crops. We evaluated two agronomic crops, saturated-soil-culture (SSC) soybean and flooded rice, in a constructed wetland system used for swine wastewater treatment. Both crop production and treatment efficiency were evaluated from 1993 to 1996 in two 4-m x33.5- ...
