  • The UV Uprising: How UV Disinfection Will Claw Its Way To Prominence
    The UV Uprising: How UV Disinfection Will Claw Its Way To Prominence

    Chlorination in all of its forms — gas, liquid, or solid — has been the primary way for treatment plants to disinfect the treated wastewater. The treatment plants that use gas chlorination must face federal regulatory oversight in the form of a Risk Management Program (RMP). Liquid chlorine plants trade in the regulatory oversight for a more expensive and less effective product. While chlorine in its solid form is good for small treatment facilities known as package plants (named for their mobility). However, ultraviolet (UV) technology is rapidly altering the landscape of disinfection throughout the industry.

    Endocrine Disrupting Compounds And Their Treatment

    Endocrine disrupting compounds (EDC) are a subset of chemicals identified as contaminants of emerging concern, or “CECs.” EDCs are chemicals that can affect the endocrine (hormonal) systems of humans and animals. Hormones regulate reproduction, growth, and behavior. Anything that can potentially disrupt those functions must be studied carefully.

ABOUT DRINKING WATER DISINFECTION

WATER DISINFECTION

Water disinfection is the process of removing unwanted chemicals, biological contaminants, suspended solids and gases from contaminated water. It is also the elimination, deactivation or killing of pathogenic microorganisms.

Methods used include physical processes such as filtration, sedimentation, and distillation, biological processes such as slow sand filters or activated sludge, chemical processes such as flocculation and chlorination and the use of electromagnetic radiation such as ultraviolet light.

Ozonators produce small quantities of ozone which is a strong oxidizing agent that kills pathogens over a short period of time.
