With the growth of the Aquaculture Industry and the demand for more fish processing come other issues that must be addressed.One of the largest issues being the treatment of blood water and production waste.
DAF – requires compressors, saturators, media and small orifices in order to create bubbles. The bubbles produced are relatively large, resulting in inefficient flotation and removal of suspended solids. The small orifices and media are easily clogged causing loss of performance and even system failure.
Aeration Chambers – require expensive and power hungry blowers to provide air supplySettling Ponds – require large areas which are not available in urban locations
TSS – Total Suspended SolidsThe more opaque the water, the less effective UV systems
The heart of this technology is in the Micro Bubble Generator (MBG ) which allows intimate mixing of water and any number of gasses. This patented process provides the ability to create ultra fine bubbles, as small as 5 µm, resulting in unprecedented flotation ability along with maximized contact between the water and the gas due to the increased surface area provided by the minute bubbles.
Muddy River Technologies is a Canadian owned and operated company based in Delta B.C.Muddy River designs and manufactures its own unique and novel proprietary technology for the water and waste water industry.Systems have been installed in the Food Processing industry, the Agriculture industry as well as for the Department of National defense and the Department of Fisheries and Oceans at their Pacific Biological Station
This uses a MASS ( Micro Air Separation System ) to introduce ambient air into the waste stream, and along with appropriate adjustments to the water chemistry, float the waste from the water producing an effluent low in BOD and TSS. Viruses, bacteria, other micro-organisms and remaining colour are dealt with in Stage Two.
This uses a special MASS unit where ozone is introduced into the stream instead of just ambient air. The ozone removes remaining colour and oxidizes any remaining blood protein in the water. Due to the total dissolution of the ozone gas in the water under pressure for a given time, there is more efficient contact for the ozone to kill or deactivate any bacteria, viruses and other micro-organisms if present.

Restrictions to Industry Growth<br />One of the largest issues being the treatment of blood water and production waste from fish processing<br />
Blood Water Waste<br />Produced during fish harvesting and processing<br />Contains sea water, fresh water, salted ice and fish blood<br />Also may contain <br />Dirt<br />Fish entrails<br />Viruses and Pathogens such as IHN <br />Must be treated and discharged<br />
Treatment of Blood Water<br />Discharge requires <br />Reduction of suspended solids <br />measured as Total Suspended Solids (TSS) and Biological Oxygen Demand (BOD)<br />Reduction of Biological Oxygen Demand and Chemical Oxygen Demand<br />measured as Biological Oxygen Demand (BOD) and Chemical Oxygen Demand (COD)<br />Disinfection of pathogens and other harmful agents<br />
Treatment Options<br />1. Dissolved Air Flotation (DAF)<br />Compressors, saturators, media and small orifices create bubbles which attach and float particles to the surface <br />Problem: bubbles are relatively large resulting in inefficient flotation and removal of suspended solids<br />Problem: small orifices and media are easily clogged causing loss of performance and system failure<br />Problem: does not treat bacteria or pathogens<br />
Conventional Blood Treatment Options<br />2. Aeration Chambers<br />Assist in reducing BOD and COD<br />Problem: requires expensive and power hungry blowers to provide air supply<br />3. Settling Ponds<br />Wastes are allowed to settle leaving clean water on surface<br />Problem: requires a very large area and considerable time. Requires periodic clean-out<br />None of these processes disinfect the water<br />
