The　potential　of　forward　osmosis　for　water　treatment　can　only　be　maximized　with　suitable　draw　solutes.　Here　a　three-dimensional,　multicharge　draw　solute　of　decasodium　phytate　(Naw-phytate)　is　designed　and　synthesized　for　removing　organic　arsenicals　from　water　using　a　hybrid　forward　osmosis　(FO)　-　membrane　distillation　(MD)　process.　Efficient　water　recovery　is　achieved　using　Naw-phytate　as　a　draw　solute　with　a　water　flux　of　20.0　LMH　and　negligible　reverse　solute　diffusion　when　1000　ppm　organic　arsenicals　as　the　feed　and　operated　under　ambient　conditions　with　FO　mode.　At　50　degrees　C,　the　novel　draw　solute　increases　water　flux　by　more　than　30%　with　water　fluxes　higher　than　26.0　LMH　on　the　FO　side,　drastically　enhancing　water　recovery　efficiency.　By　combining　the　FO　and　MD　processes　into　a　single　hybrid　process,　a　100%　recovery　of　Naio-phytate　draw　solute　was　achieved.　Crucially,　organic　arsenicals　or　Nalo-phytate　draw　solutes　are　both　rejected　100%　and　not　detected　in　the　permeate　of　the　hybrid　process.　The　complete　rejection　of　both　organic　arsenicals　and　draw　solutes　using　hybrid　membrane　processes　is　unprecedented;　creating　a　new　application　for　membrane　separations.
