pac_toc function

Calculate DOC Concentration in PAC system

Calculates DOC concentration multiple linear regression model found in 2-METHYLISOBORNEOL AND NATURAL ORGANIC MATTER ADSORPTION BY POWDERED ACTIVATED CARBON by HYUKJIN CHO (2007) Required arguments include an object of class "water" created by define_water initial DOC concentration, amount of PAC added to system, contact time with PAC, type of PAC

water must contain DOC or TOC value.

CHO(2007)

pac_toc(water, dose, time, type = "bituminous")

Arguments

• water: Source water object of class "water" created by define_water
• dose: Applied PAC dose (mg/L). Model results are valid for doses concentrations between 5 and 30 mg/L.
• time: Contact time (minutes). Model results are valid for reaction times between 10 and 1440 minutes
• type: Type of PAC applied, either "bituminous", "lignite", "wood".

Returns

A water class object with updated DOC, TOC, and UV254 slots.

Details

The function will calculate DOC concentration by PAC adsorption in drinking water treatment. UV254 concentrations are predicted based on a linear relationship with DOC.

Examples

water <- define_water(toc = 2.5, uv254 = .05, doc = 1.5) %>%
  pac_toc(dose = 15, time = 50, type = "wood")
