Question

significance of residual sodium carbonate in wastewater

Answer 1

Explanation:

The effect of Carbonate and bicarbonate ions concentration on water quality is expressed by the term Residual sodium carbonate (RSC). The risk of high sodium content in irrigation water is due to the tendency of the clay particles to absorb sodium and release the magnesium and calcium ions.

Answer 2

Answer:

The residual sodium carbonate (RSC) index of irrigation water or soil water is used to indicate the alkalinity hazard for soil. ... When dissolved sodium in comparison with dissolved calcium and magnesium is high in water, clay soil swells or undergoes dispersion which drastically reduces its infiltration capacity.
