Claim:
1. A water filtration method for treating a milk of lime solution (MOLS) that contains water, impurities and grit particles, comprising the steps of: (a) delivering the MOLS to a treatment vessel having upper and lower ends; (b) creating a turbulence in the treatment vessel to cause larger grit particles in the MOLS to settle out of the MOLS and form a bed of larger grit particles in the lower end of the vessel; (c) continuing the delivery of MOLS into the treatment vessel via a conduit that terminates within the bed of larger grit particles and through the bed of larger grit particles of clause (b) so that the larger grit particles in the bed filter out smaller grit particles and impurities from the MOLS at the lower end of the treatment vessel while creating turbulence in the treatment vessel so that water from the MOLS that has smaller grit particles and impurities filtered therefrom rises to the upper end of the treatment vessel; (d) drawing off the filtered water from the upper end of the treatment vessel.
