A Comprehensive Guide to the Types of Wastewater Pumps used in Wastewater Treatment
Today, with drastic global climate changes and widespread droughts, Waste Water Management has become more crucial than ever before. Wastewater treatment is the need of the hour in commercial, residential complexes as well as in industrial zones.
Wastewater Treatment Plants – The Pressing Need of the Hour
Wastewater treatment plants play a vital role in places like industries where large volumes of wastewater are discharged every day. Wastewater treatment not only gives you the satisfaction of doing your bit to the Earth’s most precious resource but also could reduce your overall operational costs significantly.
In industries like chemical, food processing, manufacturing, pharmaceutical and several others, wastewater treatment plants are a must to meet government regulations and rules. When it comes to treatment plants, there are three different treatment processes used like – primary, secondary and tertiary. The quality of treated water depends on the type of treatment process used.
Different industries employ different types of treatment processes, based on the quantity of wastewater, contaminants in it and the level of purity required and other miscellaneous factors. However, what remain common among all wastewater and sewage treatment plants is that they all depend on wastewater pump(s) for the process.
Role of Pumps in Wastewater Treatment
These pumps are used to move wastewater from the collection pit to the treatment plant and back into the industry.
There are plenty of wastewater pumps depending on the application and usage requirements. Here in this article, you can find all that you need to know about these pumps in one place.
Let’s get started.
Commonly used Types of Wastewater Pumps
In any wastewater treatment plant, pumps play a vital role. They help in collecting the wastewater from different parts of the plant and transfer it to the treatment plant. Once the water is purified, pumps then assist in moving the treated water to places where it is required or to a storage tank.
Based on the technique used for water treatment as well as the force required, there are several types of wastewater pumps in usage.
Let’s take a look at the types of pumps based on their operation.
As the name implies, these pumps make use of a centrifugal force to create sufficient velocity to displace the fluid through the system. Centrifugal pumps come with rotating impellers. These are parts that resemble a mechanical fan. It has a small intake and a large outlet.
Highlights of a centrifugal pump that makes it ideal for wastewater treatments:
- Simple and straightforward design that makes it practical to operate
- The moving parts are highly durable, ensuring that your pumps last for long
- Require minimal maintenance
Positive Displacement Pumps
These pumps make use of rollers, gears, impellers to displace fluid through the system. They are highly durable and are able to pump both liquids as well as slurries with lots of solid particles. The most popular type of positive displacement pumps are the diaphragm pumps. As the name states, these pumps have a chamber and a diaphragm membrane and are fitted with discharge valves.
Other Popular Types of Wastewater Pumps
There are plenty of wastewater pumps depending on the specific requirements of a particular application. Here are a few common ones:
Submersible Water Pumps
As the name suggests, these pumps are entirely submerged in the liquid they are displacing. They are mostly used to drain sewage or slurry. The pump is placed under the wastewater or sewage levels, and its operation is controlled with the help of level sensors.
While some submersible pumps can handle only liquids and are used to drain water from trash pumps and sumps, others can handle solid sewage as well.
These pumps employ axial piston principle and have a compact and light design. They can either be variable delivery pumps or fixed displacement pumps.
Water Pressure Booster Pumps
As the name indicates, these pumps are used in wastewater treatment plants to control and boost water pressure.
This type of pumps supplies kinetic energy along the pump intake.
These pumps are used when you need to keep the slurry moving through the treatment plant.
Progressive Cavity Pumps
Here, in these pumps, storage tanks or pipelines are used to transfer fluids and slurry from the suction area to the discharge area.
Apart from these, there are several other types of pumps used in wastewater treatment like mixed flow pumps, lift stations, and trash pumps.
Ultimately, the type of sewage pump you choose for your water treatment plant depends on several factors. The pump you choose must be able to withstand the abrasion and corrosion caused by the slurry or wastewater. Also, the pumps used in industrial plants are vastly different from those used in residential complexes. The former pumps must be highly durable and heavy-duty to handle large volumes effectively.
Here, at Sintech, we provide you with different types of wastewater pumps, which are customized to suit your specific requirements and applications. Our pump experts analyze the volumes of wastewater your generate, the contaminants in the water and the level of purity required, to help you select the ideal pump that minimizes overall operational and maintenance costs while lasting long term.
