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.
 After the water has served its many uses, it needs to be collected and transported to the wastewater treatment plant to be treated and returned to the environment. Wastewater flows increase along with the collection system toward the treatment plant.
 When gravity flow is not economically or technically possible, pump stations are used and the pumps are controlled to achieve a stable, secure flow to the wastewater treatment plant. The closer to the treatment plant you get, the larger the pump stations become, in order to handle the increased flows. At the wastewater treatment plant’s intake pumping station or Headworks station, the municipal wastewater network ends.
 The raw wastewater is then pumped into the wastewater treatment plant’s coarse screens and onto the treatment process. Combined pump stations are designed to handle the daily wastewater flows as well as stormwater and other surface run-off and are common in many wastewater networks. When designing a combined station, you should consider the normal fluctuations from the sewage network as well as the maximum inflow resulting from storm events.
 Both these inflow rates can differ widely from each other, and the maximum inflow can be much greater than the normal flow. Wastewater can be difficult to transport and manage with large amounts of organic solids, rags, and other waste matter that challenges wastewater pumps. High demands are placed on reliable pumping since spills and overflows will cause damage to the environment and result in fines.
 This is when Thai Khuong Pumps can help, with state-of-the-art pump station designs and proven non-clog pumps for tough media and all your specific pumping requirements.
 UNDERSTANDING YOUR CHALLENGES Wastewater Pumps, Wastewater Treatment
  • Maximum pumping reliability
  • Minimum energy usage
  • Intelligent control systems
  • Problems with hydrogen sulphide (odor)
  • Challenging pump station layout in urban areas
  • Esthetically pleasing design (invisible)

In each technology, the processing system is done through the process. With each step, the wastewater, sludge, and treatment chemicals will be different, so each stage will have dedicated pumps are used to ensure the system achieves optimal performance.

1. Sewage transportation before and after treatment: centrifugal pumps, submersible pumps

2. Transportation chemical, chemical feed: Centrifugal pump, dosing pump

3. Sludge transport, and sludge treatment: Screw pumps, centrifugal pumps, compressed air pumps

4. Gas supply system: Low-pressure screw blower

5. Mixing tank: mixer

Role of Pumps in Wastewater, 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, Wastewater Treatment

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.

Centrifugal Pumps

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 pump is the diaphragm pump. 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.

High-Pressure Pumps

These pumps employ the 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.

Agitator Pumps

This type of pump supplies kinetic energy along with the pump intake.

Circulation pumps

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 Thai Khuong Pumps, 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 you 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.
