Water Quality and Treatment Process Testing Capabilities
Corona operates a water quality and treatment
process laboratory at our Louisville, Colorado location.
Rapid Small-Scale Column Tests (RSSCTs)
RSSCTs are small-scale models of a full-scale GAC column. They require much less time and water than a full- or pilot-scale column and can be used to determine predicted breakthrough of some compounds and compare performance of different GAC types.
Corona can operate up to 4 simultaneous RSSCTs with up to two EBCTs each. RSSCTs can be designed with either the constant or proportional diffusivity method.
Used to simulate coagulation/flocculation to optimize chemical doses and compare chemical products. Have used them to test coagulants and polymers for DBP precursor removal and with PAC to evaluate MIB and geosmin removal.
Used to evaluate the adsorption of a compound onto a media (the distribution of a molecule between the solid and liquid phases).
Corrosion Coupon Testing
Corrosion coupons are used to compare relative rates of corrosion within a distribution system under various corrosion control strategies. Lead and Copper Rule Optimal Corrosion Control Treatment efforts often require this type of immersion testing.
Simulated Distribution System (SDS) Testing
Used to estimate disinfectant residual decay in the distribution system as a function of hydraulic residence time. Is also used to evaluate DBP formation in the distribution system.
Breakpoint Chlorination Testing
Used to determine approximate dose and the reaction time required to achieve breakpoint chlorination for ammonia removal.
flow through columns
Used to simulate filter, adsorption, or ion exchange media operation at pilot scale. Can be used to evaluate compound removal or compare media types..
