pH Control, Equalization and Screening

We have extensive experience in designing and providing pH control, equalization and screening Systems for a wide range of industrial applications.

pH Control Systems Applications:

• Prior to pretreatment (e.g., DAF) processes to better control chemical coagulation and flocculation
• Post pretreatment to correct pH after a pretreatment chemical program
• Prior to biological treatment to ensure optimum process conditions
• Final discharge to meet permit requirements
  System Include:
• State-of-the-art monitoring and control devices
• Properly sized and mixed neutralization tanks
• Reliable chemical delivery systems
• Acids and caustics
• CO2

Equalization Systems
Applications:

• Tanks are designed based on the flow and contaminant equalization goals of a specific application and can be provided in a variety of materials of construction
• Tank mixing systems include mechanical and diffused air options that are tailored to the type of wastewater being processed System Include:
  
  • pH monitoring and control
  • Flow and level monitoring and control
  • Off-gas control

Screening Systems
Applications:

• Prior to treatment to remove large solids from wastewater stream
• Typical screens have 0.02" - 0.03" openings to remove large solids that can damage downstream equipment System Include:
  
  • Internally-fed screens
  • Externally-fed screens
  • In-channel screens

These screening systems can be configured with optional controls and pumping stations to meet specific project needs.
