Odour control of liquid swine manure by aeration
Agriculture and Environment, 1977Abstract In Holland a number of farmers use an aerated storage basin for liquid swine manure. A description of this system is given. Two main problems are discussed: first how to minimize the high energy-consumption without odour complaints of the neighborhood and second how much nitrogen is lost, compared to untreated storage in a conventional way ...

Tile Water Quality following Liquid Swine Manure Application into Standing Corn
Journal of Environmental Quality, 2007ABSTRACTThe quality of water draining fields fertilized with liquid swine (Sus scrofa) manure (LSM) sidedressed into standing corn (Zea mays L.) at rates ranging from 0 to 94 m3 ha−1, either topdressed (TD) onto the surface, or injected (INJ) into the soil once annually for each of three consecutive years was evaluated.

Precipitation of Liquid Swine Manure Phosphates Using Magnesium Smelting By‐Products
Journal of Environmental Quality, 2007ABSTRACTSwine manure contains considerable amounts of total (P) and soluble phosphorus (PO4–P) which may increase the soil P content when applied in excess to crop requirements and, consequently, risk water eutrophication. The feasibility of using magnesium (Mg) from the by‐product of electrolysis and foundries (BPEF) for the removal of P from liquid ...

Electrolytic treatment of swine liquid manure in a full scale experiment
Journal of Environmental Science and Health . Part A: Environmental Science and Engineering and Toxicology, 1996Abstract A study was conducted to test the efficiency of electrolytic treatment in the control of odourous substances of stored swine slurries. For this purpose, a pair of copper electtrodes were placed, at a distance of 50 m from each other, in a pit (50×5.4×2.0 m) containing 540 m3 of diluted swine slurries (31 g/L COD, 1–2% TS).

Rate of Fall‐Applied Liquid Swine Manure
Journal of Environmental Quality, 2004ABSTRACTReducing the delivery of phosphorus (P) from land‐applied manure to surface water is a priority in many watersheds. Manure application rate can be controlled to manage the risk of water quality degradation. The objective of this study was to evaluate how application rate of liquid swine manure affects the transport of sediment and P in runoff ...

Archives of Environmental Contamination and Toxicology, 2008
Antimicrobials administered to livestock can be excreted up to 75% in the feces and urine. Liquid swine manure from confined animal feeding operations is generally retained in lagoon storage until it is applied as a nutrient source to crop and pasture land. Thus, the applied manure becomes a possible source of antimicrobials to aquatic ecosystems.

UV Inactivation of Bacteria in Raw and Pre-Treated Liquid Swine Manure
Environmental Technology, 2006The study was conducted to investigate the effectiveness of ultraviolet (UV) irradiation for inactivating coliform bacterial indicators in liquid swine manure samples using a laboratory-scale, low-pressure UV collimated beam apparatus. Raw liquid swine manure was brought from the field and stored at 4 'C for preliminary settling for 24 hours, which was

Agronomic Effectiveness of Calcium Phosphate Recovered from Liquid Swine Manure
Agronomy Journal, 2007A new manure treatment technology developed as an alternative to anaerobic lagoons on swine (Sus scrofa domesticus) farms includes solid‐liquid separation and subsequent recovery of soluble P as calcium phosphate from the wastewater. The objective was to determine the agronomic effectiveness of this calcium phosphate material.

SOIL INFILTRATION AND WETLAND MICROCOSM TREATMENT OF LIQUID SWINE MANURE
Applied Engineering in Agriculture, 2001Management systems are needed to minimize water quality concerns associated with liquid swine manure from large swine production facilities. Experiments were conducted to investigate the removal of ammonium–N, nitrate–N, and total phosphorus from liquid swine manure through the use of a soil infiltration and wetland system.

Chemically Enhanced Solids and Phosphorus Removal from Liquid Swine Manure
Transactions of the ASABE, 2018Abstract. Pig producers are under pressure to comply with increasingly stringent regulations aimed at protecting surface water quality. This study investigated the effectiveness of four chemical amendments [calcium carbonate (CaCO3), magnesium sulfate (MgSO4), aluminum sulfate (alum), and the polyacrylaminde (PAM) Superfloc C494] at enhancing solids ...
