How to treat wastewater in livestock farm?
Livestock wastewater is the third largest source of pollution after industrial wastewater and domestic wastewater. It has the characteristics of high organic matter concentration, high ammonia nitrogen concentration, high suspended solids and pathogenic bacteria content, etc. It is a kind of high-concentration organic wastewater that is difficult to treat. Why does livestock wastewater need to ...

SAS CMV Biogas Agricultural Methanisation, France - Case Study
In September 2015, 4 farms located in the Southern High Marned came together to operate a collective agricultural methanisation unit in Chalancey. Together, they combined to create the company SAS CMV Biogas. Nicolas LORIMIER and its associates then successfully inaugurated their first agricultural methanisation unit, recovering more than 15,940 tonnes of waste (livestock effluents) per year. To ...

What equipment is needed for a simple fertilizer manufacturing process?
If granular organic fertilizer is produced, the organic fertilizer manufacturing process needs to add an organic fertilizer granulator and dryer. The annual output of 10,000 tons of organic fertilizer generally does not require a cooler. The investment is not large, the factory site can be large or small, and generally requires 3 to 5 acres of land in total. The domestic sludge, kitchen waste ...

Installation of organic fertilizer production line equipment
As we all know, organic fertilizer production machine is the equipment that can process agricultural, forestry and animal husbandry wastes into commercial organic fertilizer. Organic fertilizer production equipment can not only effectively utilize the recyclable waste, but also bring additional economic income for related enterprises. However, if we want to achieve this effect, fertilizer ...

Production technology of bio organic fertilizer and factors affecting safety
We often use bio organic fertilizer in agricultural planting, and organic waste is its processing raw material. Chicken manure and crop straw as the main raw materials, after fermentation, they are further made into high-quality organic fertilizer products by drum granulation. The fermentation process can decompose chemical pesticide and chemical fertilizer residues, improve fertilizer quality ...

Disposing of your fallen stock during lambing season
In the UK, lambing season can start anytime from as early as November, all the way to June. Ensuring that this time period runs smoothly is vital as lambing season accounts for a large percentage of turnover. The location, size of herd and many other factors will determine when farmers decide to start preparing for lambing season. During this time, sheep farmers are preparing to care for up to 15 ...

The difference between organic fertilizer and chemical fertilizer
Difference between organic fertilizer and chemical fertilizer Chemical fertilizer, manufactured by chemical or physical methods, containing one or more nutrient elements for crop growth. Also known as inorganic fertilizers, including nitrogen, phosphate, potash, micronutrients, compound fertilizers, etc. It has strong pertinence and quick effect. There are many kinds of chemical fertilizers, the ...

The dangers of Mad Cow Disease!
The dangers of Mad Cow Disease! For the first time in over ten years Bovine Spongiform Encephalopathy (BSE) better known as Mad Cow Disease has reared its head again in the UK with cases recorded on a farm in Aberdeenshire, Scotland this October. A highly problematic virus that has previously devastated livestock in 1986 when 180,000 cattle were found to be infected, which led to a mass ...

A Guide to Compost Sheep Manure for Organic Fertilizer
Sheep manure contains protein, organic acid, cellulose, aliphatics and so on, and its organic matter content is higher other livestock manure. Without fermentation, sheep manure has various harmful bacteria that cannot be directly used on plants growing, or there would bring germs and parasite spreading. What’s worse, without proper disposal, sheep manure would generate heat to consume oxygen in ...

The ManureEcoMine pilot installation: advanced integration of technologies for the management of organics and nutrients in livestock waste
Manure represents an exquisite mining opportunity for nutrient recovery (nitrogen and phosphorus), and for their reuse as renewable fertilisers. The ManureEcoMine proposes an integrated approach of technologies, operated in a pilot-scale installation treating swine manure (83.7%) and Ecofrit® (16.3%), a mix of vegetable residues. Thermophilic anaerobic digestion was performed for 150 days, ...

Forced ammonia stripping from livestock wastewater: the influence of some physico-chemical parameters of the wastewater
In highly alkaline aqueous solutions (pH >10), the main form of dissolved ammoniacal nitrogen is the unionized free ammonia. Free ammonia, being a gaseous molecule, is easily stripped out from the solution. Increasing wastewater pH is frequently used to force ammonia removal. Herein, the effect of the variation of some physico-chemical characteristics of liquid cattle wastewater on ammonia ...

Case study - Converting livestock waste lagoons into a prosperous ROI
A Missouri project, believed to be the largest and most comprehensive livestock manure-to-energy of its type in the world, is currently under way. The project efficiently treats waste from approximately 2 million hogs. The farms are being covered by Industrial & Environmental Concepts, a designer and installer of cover systems for wastewater lagoons and tanks. Roeslein Alternative Energy of ...

Lowara pumps drive livestock operations
Animal output processed for safe disposal, reuse and renewable energy Xylem scope Xylem Lowara have installed several different types of pumps in this process cycle. Ranging from the DLV submersible pump fitted with Vortex impeller used in the pressurization of wastewater obtained from the separation of the digestate. Various high efficiency e-range pumps have also been used including the e-SH ...

Solid thickening and methane production of livestock wastewater using dissolved carbon dioxide flotation
Dilute manure is classified as wastewater due to the large quantity of water used in livestock production in Korea. Livestock wastewater treatment is required in order to reduce high moisture content and treat fluids discharged from the digestion process. In livestock wastewater treatment plants, large quantities of CO2 gas are produced at combined heat and power facilities as well as in the ...

Eco-physiological characteristics of
Pistia stratiotes and its removal of pollutants from livestock wastewaterThe effectiveness of water lettuce in removing pollutants including organic pollutants, nitrogen (NH3-N) and total phosphorus (TP) from livestock wastewater along with the physiological effects and their correlations, was studied for the first time. The results showed that the water lettuce had higher removal efficiency with low concentrations of livestock wastewater. The removal efficiency of ...

Integrated assessment of runoff from livestock farming operations: Analytical chemistry, in vitro bioassays, and in vivo fish exposures
Animal waste from livestock farming operations (LFOs) can contain varying levels of natural and synthetic androgens and/or estrogens, which can contaminate surrounding waterways. In the present study, surface stream water was collected from six basins containing LFOs. Aqueous concentrations of 12 hormones were determined via chemical analyses. Relative androgenic and estrogenic activity was ...

Adsorptive removal of sulfonamide antibiotics in livestock urine using the high-silica zeolite HSZ-385
The adsorptive removal of seven sulfonamide antibiotics using the high-silica zeolite HSZ-385 from distilled water, synthetic urine and real porcine urine was investigated. The pH greatly affected the adsorption efficiency, and the amounts of all sulfonamide antibiotics adsorbed on HSZ-385 decreased at alkaline conditions compared with that at neutral conditions. During storage, the pH and ...

Rising Meat Consumption Takes Big Bite out of Grain Harvest
http://www.earth-policy.org/data_highlights/2011/highlights22 World consumption of animal protein is everywhere on the rise. Meat consumption increased from 44 million tons in 1950 to 284 million tons in 2009, more than doubling annual consumption per person to over 90 pounds. The rise in consumption of milk and eggs is equally dramatic. Wherever incomes rise, so does meat consumption. As the ...
