With the increase in population and subsequently waste, it is crucial that waste management is done properly and efficiently. Industrial, commercial or residential zones require proper wastewater treatment.
More than residential and commercial zone, wastewater treatment is highly sought after in industrial arenas like chemical, manufacturing or food processing factories. Primary, Secondary and tertiary are the three different types of processes and the end result depends on the process used. The type of process used depends on the industry and the end results as well as the contaminants in the water.
However, one thing remains similar among all these processes and it’s the fact that they all use wastewater pumps.
What exactly are the pumps used for?
Pumps are used to basically pump the wastewater from sumps and collection pits to where it gets treated and back for usage.
There are various types of pumps for different situations. Pump and related wastewater technology have developed rapidly over the past few years. An example is leveraging one of the leading pump alarm systems to notify you when the sump is getting full or when the wastewater is overflowing.
Even within the treatment plant, wastewater pumps are used to transfer the water from different tanks for purification.
Below are few types of pumps and what they do. The first 3 are the most common types of pumps while the rest aren’t that common.
If you didn’t already figure it out from the name, these types of pumps leverage the centrifugal force to generate enough speed to move the water through the pipes. They have impellers that rotate similar to a mechanical fan. You can identify these types of pumps from their large outlet and small intakes.
Positive Displacement Pumps
Centrifugal pumps are quite simple in design, but positive displacement pumps have many components like rollers, impellers and gears which are used to move the fluid through the pipes. They are known for their high durability and their ability to move liquids containing solids(slurries).
Diaphragm pumps are most known positive displacement pumps. Diaphragm pumps have a cavity and a membrane to filter the solids and feature discharge valves alongside.
Submersible Water Pumps
As the name implies, these types of pumps are immersed in the fluid they are moving. Most common application of submersible water pumps are sewers or slurries. Because the pump is submerged it is operated using level sensors.
There are different types of submersible water pumps to handle only liquids while some types can handle solids as well.
High Pressure Pump
High pressure pumps leverage the axial piston principle and are known for their compactness and lightweight.
Water Pressure Booster Pump
The only use of this type of pump is to control and give a boost to the water pressure in the treatment plant.
This is also similar to water pressure pump. An agitator pump increases the kinetic energy of the fluid in the intake.
Progressive Cavity Pumps
This type of pump is used to transfer water from the suction area to the discharge area.
These are just a few types of pumps being used today n water treatment plants. There are other types like circulation pumps and trash pumps etc. Finally, the type of pump used depends on your requirement and end goals.
