Fertilizer solar pond: Observations from small-scale experiments with (NH4)(2)SO4 as a candidate salt
Commercially available fertilizer salt (NH4)(2)SO4 is used to establish a salinity gradient in a small outdoor tank. The hydrodynamic and thermal behavior of the pond was compared with a pond containing NaCl. For temperature gradients between 40 and 100 K/m and salinity gradients between 200 and 600 kg/m(4) the data suggest that results for (NH4)(2)SO4 are consistent with the Nielsen boundary criterion for NaCl.
