LWR Manure Treatment System


The LWR System is a great addition to any dairy! It can be placed at a flush or scrape dairy operation to effectively treat the livestock manure. In addition to the large volumes of milk a dairy cow produces, large amounts of manure are also created. To maintain and eventually grow an operation, manure needs to be treated properly to reduce any potential negative environmental impact it may have. The LWR System does just that - it is able to completely segregate and concentrate all of the nutrients in the manure from the water. This process captures the value of manure resulting in clean water, dry solid nutrients, and a concentrated liquid nutrient all available for reuse at your operation. The dry solids are rich in phosphorus and organic nitrogen, while the concentrated liquid nutrient contains ammonia and potash.

Here are some of the ways your farm will benefit from installing an LWR Manure Treatment System

Nutrient Optimization: After treatment, all of the nutrients can be economically transported to the location where they are most useful. As an example, phosphorus at many farms is either an environmental issue or of little value. By extracting the material and transporting it to a phosphorus-deficient location, it becomes a valuable product. The LWR system’s ability to concentrate and segregate nutrients reduces the overall volume that needs to be handled thus reducing costs.

Improved Profitability: The LWR system captures, segregates, and concentrates nutrients that can be used to replace fertilizer purchases or sold to local crop farmers. Generally, there is a 20 – 30% improvement in profitability with the installation of a LWR system.

Fertilizer Timing: The manure, once treated, is reduced in volume and can be applied once a year at the optimal time for crop growth — no more wasted applications. Nutrient overload is no longer an issue, instead of continuously spreading manure the fertilizer outputs from the LWR system can be precision applied as needed. This will also prevent potential nutrient runoff into fresh water sources. Excess nutrients can be sold to create an additional revenue stream.

Stable Water Source: A clean, reusable water source is established. This allows operations to recycle the majority of water that has been used in the barns thus close-looping an operation. The water can be used for irrigation, cleaning or consumption. The concentrated liquid nutrient output rich in ammonia and potash will not clog spreader hoses. In addition, there will be reduced scale in the on-farm manure piping systems.

Ammonia Capture: Under current practices, manure leaves the barn and sits in storage for several months. This allows the ammonia to “degas” from the manure, losing between 60% and 70% of the manure’s nitrogen value. Moreover, further losses occur during application. By capturing the ammonia immediately, these losses are eliminated. This process also reduces odor which will improve neighbor relations and result in a more pleasant work environment for employees.

Reduced Storage: Installing an LWR system reduces infrastructure, eliminates full lagoons, and maintains good operations due to the immediate manure processing. A small portion of the treated liquids, which are free of solids and very low in odor, are stored for their optimal use; storage of the solids requires only a small area. LWR’s small system size (60 ft. L x 24 ft. W) requires significantly less space than a lagoon or pond.

Pride in Environmental Initiatives: Manure recovery is one of the few truly sustainable environmental opportunities. This is impressive to ownership, regulators, neighbours, and the farm employees. Management and employees who are proud of their operation make for a more enjoyable work environment, which decreases turnover and improves profitability. With implementation of LWR’s technology, the farm remains a quality space where both the buildings and land assets increase in value.

Soil and Land Preservation: Conventional manure management means trucks hauling thousands of tons of manure, thereby compacting the soil and damaging its productive capability. By concentrating the liquids into a much smaller volume and removing the solids, the LWR system eliminates soil compaction and increases crop yield.
