JWC Environmental – FRC Dissolved Air Flotation

Trusted Wastewater Solutions

About the Company:

IFO wastewater screens are great for primary screening, effectively removing process water from offal (meat and feathers). IFU and IFS screens excel at secondary screening where flow rates are higher and solids loading is lower. The design of these screens and their slow speed operation reduces water usage, increases solids, discharge dryness and minimizes blinding. JWC | IPEC IFO, IFU and IFS Internally Fed Drum Screens are flexible in design to fit into your existing infrastructure, saving you time and money.

About the Solution:

PWL DAF systems are open tank, low-built separators, meaning the tanks are only built as high as 8 to 10 feet tall, as opposed to PCL plate pack DAF units which have side walls reaching upwards of 16 feet. Reason being, the PWL design is optimized for treating wastewater heavily loaded with solids that require significant amounts of free surface area for flotation and separation.

Solution Strengths, Weaknesses and Critical Indicators

Chemical flocculation technologies remove the non-dissolved particles from the waste stream typically resulting in irrigation quality “tea water”:

  • Produces a clay like cake which is high in phosphorus and with significant amounts of organic nitrogen.
  • Supported technologies include belt presses, centrifuges, dissolved air flotation systems and others; all requiring flocculants to achieve high rates of solids removal
  • There is significant variation of chemical and energy use depending on site and by technology
  • There is significant variation of operational intensity depending on site and by technology
  • There is significant variation of cost depending on site and by technology
  • Proven technology for nitrogen recovery, phosphorous recovery, storage reduction, GHG reduction, and odor control

Newtrient Comments/Opinions:

 

Suspended solids/phosphorus recovery technologies:

  • Produces a concentrated source of phosphorus from a renewable source
  • Include belt presses, centrifuges, dissolved air flotation systems and others
  • There is significant variation of chemical and energy use by site and by technology
  • There is significant variation of operational intensity by site and by technology
  • There is significant variation of cost by site and by technology
 
FRC's DAF has not been evaluated using Newtrient's 9-point scoring process because, although their process appears to be suited for use on dairy manure, they do not currently have any dairy based projects.
