LWR - First Wave
Livestock Water Recycling

Company Description:

Livestock Water Recycling Inc. (LWR) has a passion for manure and waste management. This passion grew out of a desire to clean the world's water and make a difference in how the world manages manure. LWR treatment technology is used at dairy, hog, and anaerobic digester operations. The patent protected system economically captures and concentrates valuable nutrients from manure, while recycling clean water. The result is reduced transport and handling costs, valuable fertilizer nutrients, a reusable water source, and a load off your mind. LWR's goal is to aid you in effectively managing your manure so that you can focus on milk and animal production.

Technology Description:

From the innovators at LWR, comes the First Wave System - offering you the same powerful segregation ability in a simple, easy to install, fully automated system. The result is a nutrient liquid rich in ammonia and potassium, and a valuable solid fertilizer material containing organic nitrogen and phosphorus that can be economically exported to far away fields.

 

The First Wave system eliminates solids in your lagoon and odors on your dairy!

 

Simple. Low Cost. Automatic Operation. The screen is constructed of stainless steel and mounted on an epoxy coated skid. It arrives pre-plumbed; with all electrical done for seamless connection.

 

  • Improve your operating profit margins
  • Expand your herd without acquiring more land
  • Strategically control nutrient application
  • Haul liquid free solids to far away fields
  • Eliminate solids from your lagoon
  • Control lagoon capacity

Technology 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.
  • Technologies include belt presses, centrifuges, dissolved air flotation systems and others all of these technologies require 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

LWR has recently added the First WaveTM system to their product line and are aggressively marketing to the dairy industry in the United States. In California specifically LWR has made strides to increase adoption of their technology. This system has not undergone third party testing but is reported to achieve significant phosphorus removal, there is lmited information on costs and nutrient concentration in the final product at this time.

 

The First WaveTM system is the same front end system that is used on the full scale LWR system but it eliminates the costs and operational issues associated with the membranes and does not claim to produce "clean" water. The fact that the membrane system has been removed reduces the cost and operational complexity of the system but does not reduce the costs associated with the flocculant used for removal of the TSS.

 

Newtrient has visited a LWR system on a dairy site in the United States that was originally installed as a full system but is now running as a First WaveTM system. The system visited was not operating full time, it was only operated 16 hours per day and the operator indicated that they were using a third party polymer for flocculation. The system appeared to be removing a significant amount of solids and the farm, although they were trying to minimize polymer use, reported significant phosphorus reduction in the final effluent.

 

Newtrient has reservations with this technology due to our lack of insight into the actual on-farm performance and value proposition. Newtrient has and will continue to reach out to LWR to get cost, performance and operating data on the system.
