Livestock Water Recycling

About the Company:

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, beef, hog, and anaerobic digester operations. The patented system economically captures and concentrates valuable nutrients from manure for use as fertilizer and/or feedstock for biogas generation while recycling clean water. LWR First Wave systems has been verified and validated for Carbon Credit generation. LWR has captured and analyzed over 3 million data points to date using its proprietary machine learning driven software and sensor capabilities.

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 production. The systems are scalable and come in 5 different sizes.

LWR can arrange leasing and alternate financing solutions to fit installation goals and timelines.

About the Solution:

PLANT System LWR’s patented process technology uses both mechanical and chemical treatments to remove manure contaminants and segregate valuable fertilizer nutrients at large livestock operations. As the manure effluent flows through the process, solids are sequentially removed. The result is valuable segregated fertilizer nutrients and clean water that can be reused around the barns.

Nutrient & Water Recovery

The nutrient and water recovery capacity of the PLANT System extracts up to 75% of the water from manure while concentrating and segregating nutrients. By concentrating and segregating the nutrients, you are given more control over your nutrient application which minimizes your field work. The result is clean, potable water, dry solids that are rich in both phosphorus and organic nitrogen and a concentrated stable ammonium and potassium liquid.

The Water

The water from the PLANT System is completely safe and suitable for discharge. The process removes all disease-causing pathogens found in livestock manure and can be used for flushing the barns and irrigation. With a new source of renewable, clean water, your farm will be cleaner and your manure management more efficient.

The Nutrients

The manure, once treated, is significantly reduced in volume, taking stress off of lagoons and storage pits. Nutrients can be applied once a year at the optimal time for crop growth, maximizing their value. Eliminate nutrient overload by strategically applying fertilizer as needed, where necessary, eliminating any risk of nutrient runoff. Excess nutrients can be sold to create an additional revenue stream.

LWR's PLANT System can completely treat livestock effluent - it recycles all parts of the manure so that they can be reused at the farming operation. There is zero discharge, and no additional equipment is needed to ensure proper treatment. LWR's system recovers clean water which will not contaminate groundwater sources and concentrates the nutrients in the effluent to significantly reduce handling and transport costs.

Solution 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 achieve cleaner 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 LWR has multiple systems in place and is 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 undergone third party testing in Canada on hog operations and proved that they can achieve significant phosphorus removal but the study indicated that costs and nutrient concentration in the final product was not in line with expectations.

Newtrient has not been able to confirm the claims made by LWR on a dairy site in the United States. Newtrient is aware of LWR systems that have been installed and are no longer functioning and others that are operating less than full time, the reasons behind all these operational modes is not fully understood by Newtrient at this time. 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.
