Water & Wastewater

As an engineer in today’s water industry, you are under pressure to attain higher throughput with current assets, whether you are on the potable or wastewater treatment side. You are now being asked to push the operational envelope with plant that was designed for lower demand. However, you still have to meet exacting quality standards with less chemical dosing and lower energy consumption. Not only must upgrades and retrofits be cost-effective and safe, but this must be demonstrated in advance, sometimes with new technology, like UV disinfection.

Simulation tools, such as CFD, can help evaluate alternative options quickly and reliably, steering you to the right investment decisions.

In many units such as settling tanks and disinfection units, internal flow details can have a huge influence on performance. We use CFD simulation to match retention, mixing, reaction or settling time requirements to actual residence time distribution, diagnose underperforming units, evaluate alternative design or selection options and retrofits.

Evaluations include:

• Flow distribution
• Solids settling, suspension and hold-up
• Agitator sizing
• Energy consumption
• Residence time distribution
• Dosing effectiveness

Applications include:

• Clarifiers
• Service reservoirs
• Chlorine and ozone contact tanks
• UV disinfection units
• Digesters
• Mixing zones
• Aeration lanes
