Solids Flocculation, Flotation, and Dewatering System

Solids Removal Technology for Enhanced Wastewater Treatment

  • Achieve optimal contact between solids and polymers through a highly efficient injection of compressed air and polymer into the mixing system.
  • Space-efficient design, occupying only 2-4 times less space than conventional Dissolved Air Flotation (DAF) systems.
  • Experience cleaner effluent with enhanced solids removal, resulting in typically less than 0.1% Total Suspended Solids (TSS).
  • Enjoy unmatched adaptability, with the ability to adjust to varying flow rates and wastewater compositions more effectively than traditional DAF systems.
  • Reduce chemical usage significantly, typically requiring 20%-50% less chemicals compared to DAF systems, ensuring cost savings and environmental benefits.
  • Produce drier sludge for easier handling and disposal, enhancing overall efficiency in wastewater treatment processes.

Incorporating advanced technology, the Solids Flocculation and Flotation System is meticulously designed for enhanced solids removal efficiency. Its adaptability allows it to efficiently process various flow rates while requiring significantly less chemical usage compared to conventional systems. With a smaller footprint and the capability to produce drier sludge, this system ensures both environmental compliance and cost-effectiveness in wastewater treatment processes.

Solids Floculation and Flotation System

  • Better contaminant removal rates than DAF systems
  • Adaptability–adjusts to higher flowrates
    and higher contaminant levels without equipment changes.
  • Less chemicals–uses 20%-80% less chemicals than DAF systems
  • Smaller Footprint–uses less space than other flotation and
    flocculation systems.
  • Drier Sludge–the technology of using long chain polymers
    produces drier sludge(8 to 13% drier and over 20% after decanting.)

FAQs: Solids Removal

What is solids removal?

Solids removal refers to the process of separating solid particles from liquids, typically in wastewater treatment, industrial filtration, or bioprocessing applications. This process is crucial for ensuring the quality and purity of the liquid effluent or product.

Why is solids removal important?

Solids removal is important for several reasons. Firstly, it helps prevent clogging and damage to equipment downstream in industrial processes. Additionally, it ensures compliance with environmental regulations by reducing the concentration of solid pollutants in wastewater. Moreover, solids removal improves the quality of the final product in industries such as food and beverage or pharmaceuticals.

What are some common methods of solids removal?

Common methods of solids removal include sedimentation, filtration, centrifugation, flotation, and membrane processes. Each method has its advantages and is chosen based on factors such as the type of solids, desired level of purity, and throughput requirements.

How can I choose the right solids removal solution for my application?

Choosing the right solids removal solution depends on various factors such as the characteristics of the solids and liquid, desired level of filtration efficiency, available space, and budget constraints.
