PROCESS DESCRIPTION

PROCESS DESCRIPTION In a limestone contactor, water flows through a bed of crushed sieved limestone in a similar way as it would flow through a sand filter (Spencer, 2000). The pH of water that flows through the limestone bed will be adjusted until it nears equilibrium with calcium carbonate (CaCO3(s)). The components of a contactor include a ...

to Improve Soil quality

4 For example, the calculation for the use of wood ash as a material is as follows: Wood ashes (K2CO3) molecular weight = 138 CaCO3 = 100 100/138 = 0.72 (CCE) or 72% effective compared to CaCO3 So if a recommendation from a soil called for 1,000 lbs. of agricultural lime (CaCO3), then you would divide the CCE of 0.72 (K2CO3) into the rate needed to determine the
