5 Main Types of Pumps for Your Wastewater Treatment Facility
Untreated wastewater is a big health hazard to both rural and urban communities. Wastewater increases the risk of disease and can contaminate drinking water sources. For these reasons, residential, commercial, and industrial complexes should invest in efficient wastewater treatment technology.
Pump systems play a critical role in wastewater treatment. Discover the main wastewater pumps to consider for your wastewater treatment facility.
1. Diaphragm Pump
A diaphragm pump is a positive displacement system that forces out wastewater in a specified direction by use of air or hydraulic fluid. The diaphragm membrane separates the air and the liquid and valves on either side.
Low pressure inside the pump chamber draws in wastewater into the pump. In the next stroke, pressure rises to push the wastewater out in the direction desired.
The pump is ideal for wastewater with solid content. It has great dry running capacity and self-priming capacity and maintains constant efficiency. The minimal internal components reduce the risk of breakdown and cost of maintenance.
2. Centrifugal Pump
A centrifugal pump is a dynamic displacement system that offers enhanced reliability. The pump system leverages centrifugal force, which builds velocity to force wastewater out. The simple system relies on fast-spinning impellers to move wastewater from the entry point and through the exit.
The simple design makes this a low-maintenance pump, as it doesn’t include many moving parts. Centrifugal pumps maintain a steady output towards the discharge.
The low suction power is a major drawback for this pump system. You have to prime the pump by immersing it in the wastewater to start its operation.
3. Gear Pump
A gear pump is a positive displacement unit that relies on an inter-meshing gear system to create suction and draw water into the pump chamber. The gear system also ejects water on the other side of the pump.
Gear pumps can handle an extensive range of viscosities, and the system requires minimal maintenance. The pump system also allows you to control the output of the wastewater from your facility. For a new wastewater treatment facility, this pump is easy to construct and install.
The major drawback of these pumps is the higher noise levels from interlocking gears. You must also avoid waste liquid with abrasives, as this risks ruining the gears.
4. Lobe Pump
A lobe pump system comprises a mesh of lobes that turn without contact. A set of external timing gears prevent lobe contact as water flows into the casing.
When lobes go out of mesh, space is created in the cavity and wastewater flows through. Once the lobes form a mesh without contact, they push the liquid out through an outlet.
Lobe pumps are ideal for wastewater treatment facilities as they’re reliable and efficient and also offer the best sanitary qualities. The system is also corrosion-resistant and easy to clean.
The timing gears and seals add to the internal parts of the pump system and increase the risk of breakdown. Another drawback is the reduced lift when thin liquids flow through the lobes. This can affect the rate of wastewater output.
5. Submersible Pump
A submersible pump is a dynamic displacement pump inside wastewater at a treatment plant. The pump system drains away liquids in a wastewater treatment plant. When switched on, a motor starts and rotates an impeller. The impeller provides pressure to push liquids out into a discharge pipe.
Wastewater treatment is crucial for any large facility and a pump system boosts its efficiency. The process prevents health problems, protects the environment, and helps your organization comply with local by-laws.
