1 Explain the chemical process including substances

2017-3-30  1. Explain the chemical process including substances behind why subsurface limestone so easily weathers and erodes, leading to a karst landscape? Dissolution is the removal of bedrock through chemical weathering and the action of water and since limestone is composed largely of calcium carbonate, it reacts strongly with carbonic acid, which is found in ground

Chemical Treatment of Wastewater Process

2022-1-9  Chemical Stabilization. This chemical wastewater treatment process works in a similar fashion as chemical oxidation. Sludge is treated with a large amount of a given oxidant, such as chlorine. The introduction of the oxidant slows down the rate of biological growth within the sludge and also helps deodorize the mixture.
