Vacuum Pumps for Sewage treatment

Atlas Copco pumps for the sewage treatment industry offer long-term reliability with lower utility costs

The importance of vacuum pumps in the sewage treatment industry

Sewage treatment plays a crucial role in maintaining public health and environmental safety by treating wastewater from various sources like homes, commercial buildings, and industrial facilities. Vacuum pumps are an essential component in modern sewage systems, ensuring efficient transportation and treatment of wastewater. With advancements in technology, vacuum systems have become an attractive alternative to traditional gravity sewers, especially in areas with challenging terrain or limited space. 

Vacuum pumps for sewage treatment

Vacuum pumps are used to transport wastewater from its source, whether it's a residential area, a hospital, or a large industrial plant, towards a sewage treatment plant. Unlike traditional gravity-based systems that require a specific slope to function, vacuum sewer systems use negative pressure created by vacuum pumps to move sewage through pipelines. This flexibility in design makes vacuum sewer systems ideal for areas where laying conventional pipelines is difficult or costly.

A vacuum sewer system consists of several key components:

 

  • Collection chambers and vacuum valve pits that serve as points of wastewater collection from surrounding buildings.
  • Vacuum pumps that are installed at a centralized vacuum station, these pumps maintain the required vacuum throughout the piping network.
  • Control and monitoring components that ensure smooth operations, signaling when valves should open to let wastewater into the vacuum mains.

The vacuum pumps draw in atmospheric air through specialized air inlets, which transport wastewater into the collection tanks at a vacuum station. From here, pressured sewage pumps then move the wastewater towards the treatment plant.

Why choose vacuum sewage systems?

Traditionally, gravity sewer systems have been the norm, especially in densely populated areas where slopes can be easily incorporated into the design. However, gravity systems come with challenges. They are often combined with stormwater drainage, leading to potential overflows during heavy rains. Moreover, gravity systems are more prone to sewage leaks due to aging infrastructure.

In contrast, vacuum sewage systems offer several benefits:

 

  • Flexible Design

Unlike gravity systems, vacuum systems do not require a specific slope, allowing for more versatile pipeline designs. This is particularly useful in flat terrains or areas with high groundwater levels.

 

  • Reduced Leakage Risk

Vacuum systems are fully enclosed, reducing the risk of sewage leaks and contamination.

 

  • Lower Construction Costs

Vacuum systems require smaller diameter pipes, which are less costly and complex to install compared to gravity systems.

 

  • Hygiene and Water Efficiency

Vacuum systems use less water for flushing, making them more efficient and hygienic, as they prevent direct contact with sewage.

Which sectors are vacuum sewage systems ideal for:

Industrial sewage construction (EPCs)

These companies often seek efficient solutions for sewage transport, especially in large-scale projects. Vacuum systems are an attractive option due to their lower construction costs and flexibility.

Commercial buildings and residential housing complexes

Vacuum systems can help reduce operational costs and minimal maintenance requirements.

Public services

Universities and hospitals require reliable systems to manage large volumes of sewage. Vacuum systems provide efficiency and reduce downtime, making them ideal for these applications.

Atlas Copco vacuum pumps for the sewage treatment industry

Atlas Copco provides a range of vacuum pumps specifically designed for the sewage industry. With a focus on energy efficiency, reliability, and ease of maintenance, Atlas Copco's vacuum solutions offer significant advantages over traditional technologies like oil-sealed vane and liquid ring pumps.

GHS VSD+ Screw Vacuum Pumps

The Atlas Copco GHS VSD+ Screw series offers energy savings and reduced water consumption, making it an ideal choice for large sewage systems. It maintains required vacuum levels throughout the piping network to pull sewage from one place to the collection tank. It features variable speed drive (VSD) technology, which adjusts the pump's speed based on the demand, ensuring optimal performance and energy efficiency. This leads to a lower cost of ownership compared to traditional systems.

 

DZS A dry claw vacuum pumps

The DZS A dry claw series provides a dry, oil-free solution, which is critical for the humid environments often found in sewage treatment applications. For small installations or mobile applications claw technology is ideal. The dry claw design is easy to maintain and boasts a rugged construction, ensuring long-term reliability and minimal operational costs. Its oil-free nature also means fewer risks of contamination and lower environmental impact.
