Groundwater Workshop

Session One – November 4, 2020, #921024 – 2.0 TCHs for Water Operators (18-2020) $60
Iron & Manganese Removal
This session will cover reducing iron and manganese using oxidation, detention and filtration as well as challenges when influenced by additional contaminants. This presentation will wrap up discussing piloting for Fe/Mn reduction.

Dealing with Water Hardness
chemistry for hardness removal and using lime and soda ash, pellet softening and other methods while defining hardness, discussing the general precipitation reactions and treatment processes. Process flow schemes as process components will be discussed.

Session Two – November 12, 2020, #921025 – 2.0 TCHs for Water Operators (18-2020) $60
Groundwater Treatment Intro
Will discuss what groundwater is and what regulations require it to be treated; the common contaminants and methods of treatment. A brief discussion on piloting will be included.

Reducing Arsenic
This presentation addressed the background, treatment and processes for arsenic reduction. It discusses the various forms and occurrences of this contaminant and its current regulations. The common methods of removal of; oxidation, coagulation, co-precipitation and adsorption as well as a couple alternative methods e.g., ion exchange, lime softening and reverse osmosis. A brief discussion of which application is appropriate is also included.

In Radionuclide Treatment, the outline includes the background on radium, radon and uranium. The MCLs are included and occurrences in the US. Ion exchange, HMO feed, RO/NF and air stripping are discussed and several case studies are presented.

Session Three – November 18, 2020, #921026 – 2.0 TCHs for Water Operators (18-2020) $60
Removing Ammonia from Groundwater
The presentation outline includes defining Ammonia, its regulations and treatment process options as well as the pros and cons of each method. The treatment processes of aeration, ion-exchange, RO, chlorination and nitrification will be discussed.

Nitrate Reduction in Drinking Water
This discussion will address the regulatory limits, health concerns and several methods including ion exchange, reverse osmosis and distillation approaches

PFOA/PFOS in Drinking Water
This discussion will address the history, health effects, classification, types of the contaminant, transmission, as well as discussion as to the various new and existing methods of mitigation and treatment.
