  We discuss the phenomenology of type-II seesaw by extending the Standard
Model with additional Higgs doublets and scalar triplets additionally invoked
with $\Delta(27)$ flavor symmetry for the explanation of non-zero neutrino
masses and mixings, matter-antimatter asymmetry and lepton flavor violation.
The non-zero neutrino masses can be realized via type-II seesaw mechanism by
introducing scalar triplets transforming as triplets under $\Delta(27)$ while
we add additional $SU(2)_L$ scalar doublets to have correct charge lepton
masses. We further demonstrate with detailed numerical analysis in agreement
with neutrino oscillation data like non-zero reactor mixing angle,
$\delta_{CP}$, the sum of the light neutrino masses, two mass squared
differences and its implication to neutrinoless double beta decay. We also
discuss on the matter-antimatter asymmetry of the universe through leptogenesis
with the decay of TeV scale scalar triplets and variation of CP-asymmetry with
input model parameters. Finally, we comment on implication to lepton flavor
violating decays like $\mu \to e \gamma$, $\mu \to 3 e$ processes.
