Nutrient Extraction and Recycling from Manure
Manure is full of nutrients that can be used to improve soil health and fertility on agricultural operations. Controlling the application of these remains a challenge that liquid-solid separation of wastewater can provide solutions for.
In addition to removing suspended solids from livestock runoff wastewater, flocculation enhances the removal of phosphorus from water, giving a liquid fraction that is rich in organic nitrogen and ammonia. Irrigation with this product instead of liquid manure reduces the risk of nutrient accumulation in the soil and phosphors runoff that can cause eutrophication in downstream waterways. The solid fraction, on the other hand, contains a heightened concentration of nutrients, especially phosphorus, which can be used for fertilization, composting and renewable natural gas (RNG) production. The reduction in moisture, and the increased handleability of flocs that are held together through the bridging mechanism make it easier to transport the manure and process it.
Potassium
Potassium is an essential macronutrient in agriculture, playing a crucial role in various plant physiological processes. It enhances root development, improves drought resistance, and aids in photosynthesis by regulating the opening and closing of stomata, which controls gas exchange and water loss. Additionally, potassium activates numerous enzymes involved in protein synthesis and carbohydrate metabolism, contributing to overall plant health and crop quality.
Nitrogen
Nitrogen is a crucial nutrient in agriculture, essential for plant growth and development. It is a key component of amino acids, the building blocks of proteins, and is integral to chlorophyll, which plants use in photosynthesis. Adequate nitrogen availability promotes vigorous growth, enhances leaf and stem development, and increases crop yields.
