Dynatec – Containerized MBR System

The Wastewater Membrane Specialist

Company Description:

Our Mission is to create value by providing high quality wastewater and purification treatment systems and excellent service at below average cost. The pursuit of this mission has enabled us to earn and retain the trust, confidence and business of our customers. Value is the primary force that fuels our growth. While the size and scope of our projects have grown over the years, we have maintained our small company qualities that allow us to give personal attention to every project. The principals of the corporation are intimately integrated in all project work. We will continue to pursue work for small and large companies alike and provide solutions to industrial and domestic wastewater problems. Our goal remains providing quality through products and services that produce reasonable growth.

Technology Description:

Dynatec’s containerized MBR system uses Dynatec’s  HiRate™ concept using tubular   out-of-basin membranes. This concept provides many advantages:

  • The system has the ability to operate at much higher levels of mixed liquor suspended solids (MLSS) than conventional systems and immersed MBRs.
  • High levels of MLSS allow for higher levels of treatment, improved discharge quality, lower Waste Activated Sludge (WAS) volumes as well as increased flows from the same size reactor vessels.
  • The HiRate™ concept is simple, requiring minimal operator attention.
  • An available option allows for remote monitoring and/or control for even less operator attention.
  • The system can be provided with aerobic digestion alone, or with nitrification/denitrification for total nitrogen removal.
  • The system is provided complete with system feed pumps and screening installed.
  • The membranes used provide up to 5-log levels of bacteria removal, reducing fecal discharge to non-detect levels.
  • The effluent from the system is suitable for many non-potable uses, including irrigation and toilet flushing. The effluent is suitable for further treatment, such as reverse osmosis without the requirement of any pre-treatment, since no suspended solids are present, and residual organics  are present only at low concentrations.

    Technology Strengths, Weaknesses and Critical Indicators

    Ultra-Filtration (UF) Membrane Based Nutrient Removal technologies can be used to reduce both suspended and dissolved solids depending on location specific requirements:

    • Produces low nutrient irrigation water and marketable products when paired with other technologies
    • Always produce a stream leaving membrane and stream rejected by membrane
    • Membranes of various size: Micro-filtration, Ultra-Filtration and Nano-Filtration each allowing various sized particles through the membrane
    • Depending on the membrane, effective pre-treatment to remove coarse, fibrous solids as well as fine suspended solids are important to system viability and reliability
    • Membrane failure and high pressure/energy costs can be a concern
    • Proven technology for nitrogen recovery, phosphorous recovery, and pathogen reduction.

    Newtrient Comments/Opinions:

    Membrane Based Nutrient Removal technologies:

    • Produces recycled water and marketable products when paired with other technologies
    • Always produce a stream leaving membrane and stream rejected by membrane
    • Membranes of various size: Microfiltration, Ultrafiltration and Reverse Osmosis—each allowing various sized particles through the membrane
    • Reverse Osmosis required to remove salts and achieve water suitable for discharge
    • Effective pre-treatment to remove coarse, fibrous solids as well as fine suspended solids are important to system viability and reliability
    • Membrane failure and high pressure/energy costs can be a concern
