You ask and we answer! MgWater Technical Director Matt Madolora offers solutions to common water treatment problems.

QUESTION: What is the most cost efficient way to effectively meet the EPA’s Office of Water’s Disinfection Byproducts Rules (DBPRs) for public water systems (PWSs)?

ANSWER: The DBPRs require PWSs to comply with established maximum contaminant levels (MCLs), operational evaluation levels (OELs), and maximum residual disinfection levels (MRDLs) for disinfectant residuals. The purpose is to improve public health protection by reducing exposure to disinfection byproducts. In addition, PWSs using conventional filtration are required to remove specific percentages of organic material that may react to form DBPs through the implementation of a treatment technique.

The Nutri-Mg++® process is a proprietary strategy that enables municipalities to enhance their treatment of potable water while protecting their water distribution assets and fortifying their water supply with magnesium, an essential nutrient for human health. Magnesium hydroxide can be substituted for the sodium from monovalent caustic soda, soda ash and/or other chemistries, resulting in enhanced coagulation, flocculation and sedimentation; up to a 55% reduction in TOC removal requirements, improved biofiltration and reduced inorganic sludge.

Properly refined and processed magnesia results in consistently improved alkalinity. This makes EPA requirements attainable, requires fewer chemical deliveries, and improves plant performance, resulting in a significant cost savings for the PWS.
