What Is A Waste Stabilization Pond? A waste stabilization pond is a man-made depression confined by earthen structures. It is designed and built for wastewater treatment, which reduces the organic content and removes pathogens from wastewater. Waste stabilization ponds may be used as part of a sequence of treatment processes where the final step is […]
What Is Aerated Lagoon? An aerated lagoon is a waste water treatment process that uses a large basin with mechanical aerators to maintain aerobic conditions and prevent settling of biomass. Wastewater flows through the lagoon, retaining for a set period of time, and exits through an outlet. The initial microbe population is lower than in […]
What Is Extended Aeration Process? Aeration is a process that uses air or oxygen to treat wastewater. The most common types of aeration include conventional aeration and extended aeration. Extended aeration is a type of aerobic treatment process for waste water and water bodies that may be contaminated with harmful organic matter. This method forces […]
What Is A Facultative Lagoon? A facultative lagoon is a waste stabilization pond used for the biological treatment of industrial and domestic wastewater. The water flows into the lagoon and then through an aerator, mixed with air and allowed to settle out before being pumped out again. The purpose of these lagoons is to reduce […]
What Is A Reclaimed Water? Reclaimed water refers to wastewater treated for reuse. With modern technology, it can be used for various purposes after treatment, depending on the source and delivery method. Water reclamation refers to the process of converting wastewater from cities or industries into reusable water for various purposes. The types of reuse […]
What Is Upflow Anaerobic Sludge Blanket Digestion? The UASB process uses anaerobic microorganisms to degrade wastewater in a tank, with a blanket of granular sludge suspended by upward flow and gravity aided by flocculants. After 3 months, the blanket matures and small granules with bacterial aggregations form. These aggregations grow into dense biofilms known as […]
What Is An Imhoff Tank? The Imhoff tank is a chamber designed for the treatment of sewage. It was named after the German engineer Karl Imhoff who lived from 1876 to 1965. The tank is comprised of two separate chambers: the upper chamber where the sewage undergoes clarification through settling and sedimentation, and the lower […]
What Is A Manhole? The term “manhole” is also used informally to refer to utility covers mounted on the surface of streets, sidewalks, and driveways, such as those for electrical or fibre optic cables or telephone lines, or cable television wires. The word “manhole” dates back at least as far as the early 19th century; […]
What Is A Groundwater Recharge? Groundwater recharge is the process where water flows from the surface to underground aquifers, replenishing the groundwater supply. It happens both naturally, through precipitation, and artificially, like when rainwater or treated water is directed to the subsurface. The primary way water enters an aquifer is through recharge. Estimating recharge rates […]
What Is A Utility Vault? Utility vaults are underground structures that provide access to underground public utilities such as water and sewer lines. They minimize costs associated with digging up roads or sidewalks during repair or construction projects. The purpose of a vault is to house utility lines, such as electric and gas lines. The […]
