USING POLYALUMINIUM COAGULANTS IN WATER

  • How does sap evaporation improve water retention?
  • Improved retention is from reduced evaporation and from SAP absorption of water from soil during drying. Efficiency of SAP application depended on soil type, SAP type, SAP concentration, and their interactions. Superabsorbent polymer (SAP) efficiency in water absorption and release depends on soil properties and SAP type and concentration.
  • Does sap concentration affect water retention capacity?
  • Improvement in water holding capacity increased with an increase in SAP concentration. Improved retention is from reduced evaporation and from SAP absorption of water from soil during drying. Efficiency of SAP application depended on soil type, SAP type, SAP concentration, and their interactions.
  • What are the advantages of adding a sap to the soil?
  • A main advantage of adding a SAP to the soil seemed to be its ability to absorb water from the soil during a drying period and thus decrease water loss to evaporation and increase water availability for crop production.
  • Which sap is most effective in retaining water after 10 h drying?
  • The SAP with the large-size beads (BJ-2101M) appeared to be the most effective SAP in maintaining the smallest fraction of water loss in the soil–SAP mixtures among the four SAPs after 10 h drying. Our results clearly showed that SAPs mixed with soils reduce the contribution of clay to the water retaining ability of soils even at drying conditions.
