  In this note, we prove an effective linear volume growth for complete
three-manifolds with non-negative Ricci curvature and uniformly positive scalar
curvature. This recovers the results obtained by Munteanu-Wang. Our method
builds upon recent work by Chodosh-Li-Stryker, which utilizes the technique of
$\mu$-bubbles and the almost-splitting theorem by Cheeger-Colding.
