Utilization of fly ash for treatment of coal mines wastewater : Solubility controls on major inorganic contaminants
Abstract Acid mine drainage (AMD) has been reacted with coal fly ash in a 24 h equilibration time using 1:3 and 1:1.5 FA:AMD ratios by weight to produce neutral and alkaline process waters. TheExpand

Partitioning of major and trace inorganic contaminants in fly ash acid mine drainage derived solid residues
Acid mine drainage was reacted with coal fly ash over a 24 h reaction time and species removal trends evaluated. The evolving process water chemistry was modeled by the geochemical code PHREEQC usingExpand

Impact of dairy manure addition on soil nutrients in northeast and south central Kansas
Sixty four percent of the fields (14 of 22) in northeast and south central Kansas would be able to apply dairy manure on a nitrogen basis if the current swine manure application regulat ions wereExpand

Passive neutralisation of acid mine drainage by fly ash and its derivatives: A column leaching study
Abstract Active treatment of acid mine drainage using fly ash (FA) generates solid residues. This work investigated the suitability of using the solid residues (SR) generated from the process forExpand

Manure and lagoon nutrients from dairies using flush systems
Nine primar,y lagoons and solids storage basins were sampled on Kansas dairies using flush systems. These samples were analyzed for nutrient content of wastewater and sand manure. The manure moistureExpand
Labor requirements for handling manure from concrete basins
Time requirements for loading a manure spreader and traveling to and from the field varied from 20 to 30 min per load. However, standardizing the data showed that 5 to 7 min were required per 1,000Expand
Nutrient analysis of sandladen dairy manure
Nine concrete storage basins were sampled on Kansas dairies and analyzed for nutrient content of sandladen dairy manure. The manure average 75% moisture content during the three sampling periods. TheExpand
Impact of Soil Phosphorus Limits on Fields Receiving Dairy Waste
Sixty four percent of the fields (14 of 22) in northeast and south central Kansas would be able to apply dairy manure on a nitrogen basis if the current swine manure application regulations wereExpand
