Abstract: A method is described for improving water retention in soil, which involves mixing a super absorbing resin (SAR) composite with the soil. The SAR composite comprises a natural pozzolan and at least one polymer or copolymer. The SAR composite may be in the form of granules having an average longest dimension of 0.2-10 mm, though the SAR composite may be pelletized or formed in other sizes. The SAR composite may release water at a faster rate in a soil when exposed to drought conditions.

Abstract: Macroparticulates may be formed through at least partial self-assembly by reacting an epoxide-containing (meth)acrylic polymer or copolymer with a compound bearing a nitrogen nucleophile. An internal cavity may be formed when functionalizing the (meth)acrylic polymer or copolymer in the presence of a hindered amine base. When appropriately functionalized, the macroparticulates may be used to sequester a contaminant from a substance in need of contaminant remediation, such as produced water or flowback water from a wellbore job site. Reclaimed water obtained from the macroparticulates may be utilized to form a treatment fluid. The macroparticulates may be located within a continuous flow line, particularly within a removable cartridge, to promote removal of at least one contaminant from a substance in need of contaminant remediation. The substance in need of contaminant remediation and/or the macroparticulates may be visually or spectroscopically interrogated to determine whether the macroparticulates have become saturated with contaminant.
