What is wastewater treatment?
Additional wastewater treatment processes are required to remove additional pollutants, such as the nutrients nitrogen and phosphorus. If a treatment facility is to remove 90 percent of the nutrients in the influent (an anticipated requirement for some HRSD facilities), it is necessary to install additional processes that use microorganisms that differ from those in secondary treatment, use additional chemicals and add an effluent filtration system. This significantly increases plant construction and operation costs.
What is the primary treatment of wastewater?
Primary Treatment. When wastewater enters the treatment plant, it flows through a screen that removes large floating objects such as trash, sticks and rags. The wastewater then typically flows to a grit chamber and a sedimentation tank.
What is secondary treatment?
Secondary Treatment. Secondary treatment facilities speed up the processes of nature, allowing microorganisms (bacteria and other organisms) to remove 80-90 percent of the "organic matter" - or human, animal and plant waste. The most commonly used secondary treatment technique in HRSD plants is the activated sludge process.
What are the requirements for wastewater treatment?
The final treated wastewater must meet strict state and federal permit requirements established under the Clean Water Act. These requirements are designed to protect both human health and aquatic life in our waterways. Laboratory workers monitor water quality frequently at the wastewater treatment plant, to make sure it meets permit limits.

What are the different types of water treatment systems?
The most common types of household water treatment systems consist of: 1 Filtration Systems#N#A water filter is a device which removes impurities from water by means of a physical barrier, chemical, and/or biological process. 2 Water Softeners#N#A water softener is a device that reduces the hardness of the water. A water softener typically uses sodium or potassium ions to replace calcium and magnesium ions, the ions that create “hardness.” 3 Distillation Systems#N#Distillation is a process in which impure water is boiled and the steam is collected and condensed in a separate container, leaving many of the solid contaminants behind. 4 Disinfection#N#Disinfection is a physical or chemical process in which pathogenic microorganisms are deactivated or killed. Examples of chemical disinfectants are chlorine, chlorine dioxide, and ozone. Examples of physical disinfectants include ultraviolet light, electronic radiation, and heat.
