Wastewater Treatment

Overview

Overview

Wastewater treatment is the process of removing contaminants from water discharged from domestic, industrial or commercial premises as well as surface run-off. Wastewater treatment typically utilises mechanical, biological, and chemical processes to remove these contaminants. Grundfos can supply a whole range of components for a complete mechanical, biological, and chemical wastewater treatment plant.

The process of wastewater treatment varies from simple tanks, relying solely on sedimentation, to the refined treatment processes with advanced biological treatment that we know today. Treatment aims at reducing the pollution contained in the wastewater such as bacteria and viruses, oxygen consuming components, nutrients, pharmaceuticals, chemical substances and heavy metals from wastewater before it is discharged to the receiving waters.

Grundfos has decades of experience developing controller and monitoring systems for pumping solutions and manufactures its own pump motors for all fluid types and flow requirements. This ensures a perfect match with hydraulics, motors, electrics, and all other mechanical components that make up a comprehensive pumping solution, ensuring the best possible efficiency point. 

Control and monitoring systems increase the potential for improving both efficiency and reliability. Grundfos supplies external variable speed drives (Grundfos CUE) that are pre-programmed for the Grundfos range of products, ensuring optimal operation.

The high-efficiency motors developed by Grundfos, with or without an integrated or external variable frequency drive, meet and in some cases exceed the requirements set by motor-efficiency legislation around the world. Considering that on average 85% of a normal pump system's Life Cycle Cost (LCC) is energy costs, switching to Grundfos pumps with high-efficiency motor technology can mean a LCC reduction of up to 50% and a reduction in environmental impact.

Grundfos offers a broad range of equipment designed specifically for wastewater handling and treatment. The sustainability of a sewage treatment plant requires that the solution is durable, ensuring cost effective and trouble-free operation. Grundfos remains with you and your solution for the duration, offering commissioning agreements to ensure correct installation and service agreements offering cover for all eventualities, from routine maintenance to spare parts.

Simulation for optimising tank design

Flow simulations provide designers with documentation that a mixer/flowmaker configuration will meet specifications.

Flow simulations using Computational Fluid Dynamics (CFD) give designers the chance to compare real-life outcomes of mixer and flowmaker configurations before the design is finalised. Grundfos has been systematically providing CFD flow simulations as documentation since 2004.

CFD simulations enable designers to find the optimal position and number of mixers to:

  • Ensure solids remain in suspension
  • Maintain an optimal velocity in the aerobic zone
  • Ensure against dead zones
  • Prevent backflow during aeration

Is it worth the effort?
When there is more than one mixer in a tank, there is a risk that they actually work against each other. Efficiency drops, and in some cases operators install more mixers to reach the desired effect. A flawed design can be very expensive to rectify.

CFD simulations visualise the effect different mixer configurations will have on the flow in a given tank. By comparing different configurations and positions, it is possible to find a balance between capital expenditure in terms of the number of mixers installed and operating expenditure in terms of mixing effect/kWh.

Most process tanks are based on one of few typical shapes, so it is normally relatively fast and economic to apply a CFD simulation to a specific project.

Please contact Grundfos next time you are involved in a wastewater treatment plant project. A CFD simulation could save a lot of time and expense.
