Ardmore is receiving an infrastructure grant of $22.5 million for improvements to the Ardmore Wastewater and Treatment Plant, including the replacement of the wastewater treatment plant.
Lime or lime-soda softener control is usually based on treated water alkalinity and hardness. Samples are tested to determine the alkalinity to the P (phenolphthalein, pH 8.3) and M …
The Iowa Department of Natural Resources directed those cities using lime softening in drinking-water treatment to stop digging new lagoons to dispose of lime sludge.
Water treatment and sugar beet limes have neutralizing values of up to 120 and 80-90, respectively. Hence, it takes less water treatment lime, and often more sugar beet lime to neutralize acid soils. Users should have a laboratory analysis performed on any material before it is applied to their fields.
It is a shallow layer of highly permeable limestone under a portion of South Florida. It underlies Broward County, Miami-Dade County, Monroe County, and Palm Beach County, a total of about 4,000 ...

Historical Weather. Below are weather averages from 1971 to 2000 according to data gathered from the nearest official weather station. The nearest weather station for both precipitation and temperature measurements is HEADL which is approximately 13 miles away and has an elevation of 370 feet (140 feet higher than Limestone Creek Sewage Treatment Plant).
Hydrated lime is created when quicklime chemically reacts with water. It is hydrated lime that reacts with clay particles and permanently transforms them into a strong cementitious matrix. …
To efficiently remove nitrogen(N) and phosphorus(P) from wastewater treatment plant effluent (WWTPE) with insufficient carbon, sulfur-pyrite-limestone autotrophic denitrification (SPLAD) reactor and gravel heterotrophic denitrification (GHD) reactor were constructed. Results showed that SPLAD was successfully started after 8 days and was faster than GHD.
Lime has numerous applications in treating industrial wastewaters, especially where neutralization of acidic wastes is required. In steel plants, sulfuric acid-based waste pickle …
A limestone water treatment plant in Finland has successfully reduced the amount of ammonia present in the drinking water to just 20%. At yet another Finnish water treatment plant, technicians increased the alkalization water (a good thing, since acidic water rots teeth and causes other problems).
