Lime treatment to improve frictional resistance and stability of stiff clay slopes
… thus affecting the economy. Introducing lime, cement or other stabilizers to the potential shear zone or along the pre-existing slip surface of reactivated landslides is an alternative to increase the stability and reduce the rate of movement. The effectiveness of lime treatment of soils …

The treatment of a munitions manufacturing waste with lime, chlorine and permanganate
Lime, chlorine, and potassium permanganate have long been important chemicals in the treatment of municipal and industrial wastewater. Their effectiveness in treating munitions manufacturing wastes was determined in a laboratory study using bench scale coagulation tests designed to simulate the …

Engineering aspects of calcium carbonate and magnesium hydroxide precipitation in waste water reclamation
… some of the major problems associated with lime treatment in waste water reclamation. The contribution to knowledge is briefly outlined below. One of the major problems associated with lime treatment is the instability of lime-treated effluent, which may result in serious calcium carbonate …

Nitrification in a pine bark medium
… containers was treated with either 0, 3 or 6 kg lime m⁻³. “Soil” solution data and NO₃-N accumulation rate (NAR) data showed an earlier nitrification of NH₄-N at the 6 kg lime compared to the 3 kg lime treatment whereas NO₃-N was not found at the 0 kg lime treatment. In a 3rd experiment, pine …

Estudo da permeabilidade e estrutura de solo-cal
… and structure of a soil when stabilized with lime is the objective of this thesis. First, a bibliographic review is made on permeability of clay soils, and the modifications of physical soil properties due to lime treatment. A special permeameter was built which uses compressed air and permits …

Evaluation of Moisture, Suction Effects and Durability Performance of Lime Stabilized Clayey Subgrade Soils
… and unconfined compressive strength (UCS) of lime treated clayey subgrade soils. Two subgrade soils: the AASHTO class A-6 and A-7-6 are collected from US 491 road site in New Mexico. Cylindrical soil specimens are prepared according to NCHRP 1-28A at three lime percentages: 0%, 5% and 7% which …

EVALUATION OF BASE LINERS TO REDUCE NITROGEN AND SALT LEACHING FROM POULTRY LITTER STORAGE STOCKPILES TO THE UNDERLYING SOIL - A FIELD COLUMN STUDY
… in each column was covered with one of five treatments: alum, gypsum, lime, plastic, or control (no material). Nitrogen, K and Na concentrations increased between 15 and 91 days of storage. Ammonium losses under alum and lime treatment were not different from the control. Alum created adverse …

Water quality and productivity changes associated with the liming of a soft water lake
… with calcium carbonate for four years. The limestone treatment was done by revolving limestone drums installed above the lake on Meadow Creek. The limestone drum provided continuous treatment throughout the period. Limnological conditions of Meadow Creek and Sherwood Lake were monitored …

Membrane Processes for Sustainable Energy Applications
… from ligno-cellulosic biomass requires pretreatment of the biomass to hydrolyze hemi-cellulose, separate lignin and reduce cellulose crystallinity. During the pretreatment by dilute acid hydrolysis (or other method of hydrolysis), several grams of acetic acid per liter of hydrolysate are …

Spectroscopy as a tool for the management of soil acidification
… productivity in agricultural crops. While lime (CaCO3) application is an effective remedy for surface soil acidity, improved application and detection methods are required to manage acidity in subsurface layers. Testing the efficacy of acidity management through the soil profile at a high …
