Being aware of and controlling chemical dose rates in water treatment is important to avoid product wastage and minimize the residual chemical load discharged into the environment. Convenient, easy-to-use calculators will assist with cost projections during budget preparation and allow to verify whether the actual chemical usage is on track with the budget during the project execution phase.

Jar tests on construction projects help select and quantify a chemical treatment program for removal of suspended solids from stormwater run-off.  As the project progresses, jar tests help confirm that the chemicals are not "over-dosed" resulting in product wastage and potentially harmful residual release or "under-dosed" resulting in non-compliant site discharges.
