Jan 01 2007 · When there are extremely high acid loads foaming may occur especially when organic matter is also present in the waste. Lime-Slurry Treatment for Acid Wastes Mixing acid wastes with lime slurries is an effective procedure for neutralization (Hoak 1944 Rudolfs 1943a b Smith 1943). The reaction is similar to that obtained with limestone beds.

A comparison of neutralization efficiency of chemicals

The results of neutralization experiments with lime stone or calcium carbonate suspension in water are presented in Table 5. The requirement of limestone is shown at three stages of neutralization corresponding to pH 4.8 6.0 and 7.2 and it is seen that the limestone requirement is 4.0 6.0 and 14.0 g respectively for 1 cu m of Plant water.

Limestone Treatment of Acid Mine Drainage

The high cost of lime as compared to limestone and the poor quality sludge (slow settling large volumes and low solids content) has stimulated work in the utilization of limestone. This paper reports on the current state-of-the-art of limestone treatment of AMD. Neutralization Process. The neutralization process provides the following benefits

Acid neutralizing capacityWikipedia

Acid-neutralizing capacity or ANC in short is a measure for the overall buffering capacity against acidification for a solution e.g. surface water or soil water.. ANC is defined as the difference between cations of strong bases and anions of strong acids (see below) or dynamically as the amount of acid needed to change the pH value from the sample s value to a chosen different value.

Acidified Lakes and Ponds VCE Publications

May 01 2009 · Hydrated lime (calcium hydroxide Ca(OH) 2) and quicklime (calcium oxide Ca(OH) 2) generally are not recommended for treating surface waters because they are corrosive difficult to control and may not be legal to apply.Hydrated lime and quicklime have been used for acid neutralization because less is needed (they have higher neutralizing values than pure limestone) but both are caustic.

NEUTRALIZATION CHEMICALS

The basic principle of neutralization of a base or acid requires either hydroxide ions (OH-) in a base for neutralizing an acid or hydrogen ions (H ) in an acid for neutralizing a base. Neutralization with Acid Since most chemicals listed above will work to neutralize waste streams cost considerations will often determine the selection.

What happens when acid reacts with limestone Questions

Jun 15 2008 · Limestone is mostly made up of the mineral calcium carbonate (CaCO3). This is not very soluble so rocks don t dissolve very quickly. But if you add an acid you add hydrogen ions (H ) which will react with the carbonate to form hydrogen carbonate HCO3- ions which are very soluble in water and the limestone will dissolve. Or if there is more acid two hydrogen ions will
