This slide presentation begins by defining calcite contactors as atreatment device throughwhich water flows anddissolves a packed-bedof calcite (calciumcarbonate). It outlines case study designassumptions that include: permeate quality; finished water goal; blended contactor/by-pass quality; and, post caustic soda. It lists the required criteria fordesigning a calcite contactor that include:by-pass percent;hydraulic loading rate;media depth;calcite particle size; and,calcite purity. Case study consumption and costs are given, along with advantages and disadvantages.
