Wastewater entering the treatment plant includes items like wood, rocks, and even dead animals. Unless they are removed, they could cause problems later in the treatment process. Most of these materials are sent to a landfill. 2. Pumping The wastewater system relies on the force of gravity to move sewage from your home to the treatment plant.

What are the different types of wastewater treatment?
Wastewater from commercial and industrial processes is usually divided into the following four categories and dealt with accordingly: 1. Some wastewater can be treated on-site and reused within the plant for various purposes. 2. There are some wastewater treatment plants that are designed to treat industrial wastewater. 3.
What are the basic components of a wastewater treatment plant?
The type and order of treatment may vary from one treatment plant to another, but this diagram of the Ottawa-Carleton wastewater treatment plant illustrates the basic components. The primary level of treatment uses screens and settling tanks to remove the majority of solids.
Which wastewaters are difficult to treat?
Some wastewaters are more difficult to treat than others; for example, industrial wastewater can be difficult to treat, whereas domestic wastewater is relatively easy to treat (though it is increasingly difficult to treat domestic waste, due to increased amounts of pharmaceuticals and personal care products that are found in domestic wastewater.

How does wastewater get to the treatment plant?
Sewers collect the wastewater from homes, businesses, and many industries, and deliver it to plants for treatment. Most treatment plants were built to clean wastewater for discharge into streams or other receiving waters, or for reuse.
How many types of wastewater treatments are there?
There are three main stages of the wastewater treatment process, aptly known as primary, secondary and tertiary water treatment.
Which is a type of wastewater?

What is a product of wastewater treatment?
Sewage sludge is the solid, semisolid, or slurry residual material that is produced as a by-product of wastewater treatment processes. This residue is commonly classified as primary and secondary sludge.
What is primary wastewater treatment?
Primary treatment removes material that will either float or readily settle out by gravity. It includes the physical processes of screening, comminution, grit removal, and sedimentation.
What are the types of wastewater you can find two types of wastewater household and wastewater?
There are two types of wastewater. Blackwater contains human waste and harmful pathogens. Greywater consists of water discharge from sources such as showers, sinks and washing machines. Although greywater is not clean enough to drink, it does not contain harmful pathogens.
