Introduction The McDowell Creek Wastewater Treatment Plant (WWTP) serves as a critical environmental safeguard for the rapidly growing northern Mecklenburg County region. Operated by Charlotte Water, this 12-MGD facility is strategically located within the Mountain Island Lake watershed—the […]
Introduction to Tertiary Filtration Selection For municipal and industrial engineers, the tertiary filtration stage is frequently the final safeguard between regulatory compliance and permit violations. As National Pollutant Discharge Elimination System (NPDES) permits tighten—particularly regarding total phosphorus (TP) limits of < 0.1 mg/L and strict turbidity requirements for Title 22 water reuse—the margin for error […]
Introduction One of the most frequent debates in municipal advanced treatment design centers on the selection of tertiary filtration technology. Engineers are often tasked with balancing the stringent pathogen rejection of low-pressure membranes against the energy efficiency and simplicity of depth filtration. This dichotomy is best represented by analyzing DuPont – Memcor vs Aqua-Aerobic for […]
1. Introduction Filtration systems represent a critical unit process in both municipal water treatment and wastewater resource recovery facilities. As regulatory limits for turbidity, suspended solids, phosphorus, and pathogens tighten, the reliance on advanced filtration technologies has intensified. In the context of potable water, filtration serves as the primary barrier against protozoan cysts (Giardia and […]
Wastewater treatment is an essential process to ensure that water returned to the environment is free from harmful pollutants and can support aquatic life. Among the diverse technologies employed, cloth media filters stand out for their effectiveness in filtering out fine particulates from wastewater. These filters operate by using layers of cloth material as a […]
