Technology Description:

Membrane systems, type UF and RO

Membrane separation processes are based on a straight forward separation method, whereby specific filters will let water flow through while it retains suspended solids and bigger molecules. The selection of the right type of membranes and working conditions are important to determine the water quality and liquid fertilizer.

Technology Strengths,Weaknesses and Critical Indicators

Clean Water Membrane Systems can be used to reduce both suspended and dissolved solids depending on location specific requirements:

  • Can produce recycled dischargeable water (RO) and marketable products when paired with other technologies
  • Always produces two streams leaving system a stream retained and a stream that permeates the membrane.
  • Membranes of various size are often used together to get to clean water: microfiltration or ultrafiltration membranes first followed by reverse osmosis membranes—each allowing various sized particles through the membrane
  • Reverse Osmosis membranes are required to remove salts and achieve water suitable for discharge
  • 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 storage 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 

 

Nijhuis’s membrane filtration system, part of their Genuis System, includes Ultrafiltration and Reverse Osmosis.  Ultrafiltration is used to remove fine suspended solids from manure that has been pre-treated to remove course, fibrous solids by centrifuge and DAF.  Ultrafiltration effluent is further processed by an ammonia stripping system to remove ammonia-nitrogen with ammonium sulfate as a final product (see Nijhuis ammonia stripping technology).

 

Newtrient will continue to work with Nijhuis to further refine the cost and performance information as more information comes in with new commercial dairy installations.
