Front-end loading (FEL) is the process for conceptual development of projects in processing industries. It involves developing sufficient strategic information and making decisions to commit resources in order to maximize the potential for success. FEL is usually followed by detailed design or detailed engineering.
Sewerage is the infrastructure that conveys sewage or stormwater using sewers. Learn about the history, types and challenges of sewerage systems, such as corrosion, water table lowering and fecal sludge management.
Learn about the definition, comparison, applications and types of decentralized wastewater systems, which treat and dispose or reuse wastewater from small and low-density communities, buildings and dwellings. Find out the advantages, challenges and examples of decentralized wastewater treatment technologies.
Learn about waste stabilization ponds, a natural treatment process for wastewater that uses different types of ponds with varying oxygen levels. Anaerobic ponds are the first stage of the system, where organic matter is digested by bacteria.
Learn about the history, operations, and controversies of the largest sewage treatment facility in Los Angeles, California. The plant treats 450 million gallons of wastewater per day and produces reclaimed water, biogas, and fertilizer.
Learn about the different types of wastewater treatment plants, such as sewage, industrial, agricultural and leachate, and the processes they use to remove contaminants and produce effluent. Find out the global trends, challenges and examples of wastewater treatment and reuse.
A constructed wetland is an artificial wetland that treats wastewater or stormwater using natural processes and plants. Learn about the two main types of constructed wetlands (subsurface and surface flow), their applications, and how they remove pollutants such as nutrients, pathogens, and heavy metals.
A sewer pipe is normally at neutral air pressure compared to the surrounding atmosphere.When a column of waste water flows through a pipe, it compresses air ahead of it in the system, creating a positive pressure that must be released so it does not push back on the waste stream and downstream traps, slow drainage, and induce potential clogs.
