lime dosing calculation for ph correction

The pH of solutions can be altered by adding acids and bases. Soil pH management The first step is to determine the soil pH required for your crop. A raw water supply is treated with an alum dosage of 25 mg/L. In other words, the pH won't shoot up to 12. If you put too much ,acid, into a solution, you will have to use a base to raise the pH once again. The calcium hardness first decreased in ...

This variation is represented by the ,equation, y =-0.0003x2+0.0386x+5.0614 (r 2 =0.44). The VA/TA ratio was stable with the HRT variation since the values reported were not different from each other. The ,equation, y=0,0003x 2 +0.0386x+0.41 represents the VA/TA variation with the high correlation coefficient (r …

chemical reaction for cement

Chemical, reactions in concrete are both due to the materials used in the mix and those it may have come in contact with. The cause of cracking is the expansive reactions between the aggregate and the alkalis in the cement paste. The ,chemical, reaction occurs between active silica and alkalis producing an alkali-silica gel as a by-product. Get Price
