Quebec company unveils pig slurry treatment technology. INRS will monitor the performance of the Solugen process for the treatment of pig manure by performing physical-chemical analyses at various stages. This week, André Beaulieu Blanchette, president of Développement Solugen Inc., unveiled his innovative process for the treatment and ...

The slurry used was taken from a pig farm located near Castelo Branco. Slurry acidification was performed by addition of concentrated sulphuric acid (5ml to 1L slurry) to reach a final pH of 5.5. Slurry separation was performed on farm with a decanter centrifuge. Slurry application rates were of 80 kg N ha-1 in autumn (oat crop) and 170 kg N ha ...

Phosphorus emissions are often not explicitly clay minerals (Li, 2006) and organic matter (Acosta et al., 2011). mentioned in LCA studies on treatment of pig slurry, due to a lack of The separation efficiencies for these elements are quite high data (Lopez-Ridaura et al., 2009) or due to the assumption that P in (Popovic et al., 2012), so the ...

The untreated pig slurry and continuously acidified pig slurry were stirred prior to full-scale separation at the pig farm by means of three different separation technologies: (i) a screw press (Börger BS50, Börger , Borken-Weseke, Germany), (ii) flocculation using polymers and drainage with a filter band separator (AL-2 model 812P ...

During the treatment of raw pig slurry by batch aerobic fermentation, the presence of surfaces for bacterial attachment resulted in a 1,000-fold increase in the microbial population. In the absence of such surfaces, a 65% reduction of the chemical oxygen demand (COD) of the manure was obtained after 168 h of aeration, whereas a value of 90% was ...

The technologies for slurry treatment analysed are currently used in Denmark or have high potential applicability. Emissions from slurry, liquid and solid fractions were analysed from the moment the slurry was excreted by pigs until 20 years after field application, as modelled by the Farm-N model (Hutchings, 2010). The effects of all emissions ...

With the goal of alleviating the environmental pressures caused by pig manure treatments, this study tried to 1) evaluate the environmental impacts of 1 ton pig slurry under each treatment technology, 2) identify environmental hotspots of each technology, and 3) propose strategies to promote appropriate treatment methods.

Liq. pig manure is converted to fertiliser by: (a) adding to the manure a soln. of P2O5 and K2O; (b) mixing the soln. with a prod. which can retain water, in the form required in the final prod., to give a shaped, conditioned fertiliser, which is (c) dried. The ratio of P2O5 and K2O in the soln. is such as to give the required ratio of N, P and K in the final prod., and is a function of the ...

On commercial pig production farms in South East (SE) Asia, the liquid effluent is often discharged into rivers. The discharge is a hazard to the environment and to the health of people using water from the river either for consumption or for irrigation. Therefore, a simple percolation biofilter for treatment of the liquid effluent was developed.

Slurry treatment, different solutions and technologies. Pig farming is of major economic importance in many countries in the world. This figure has increased year on year over several decades, with industrial-type farms proliferating despite land-use criteria, thereby contributing to a marked imbalance between livestock farming and agriculture.

Polán and Consuegra plants for efficient treatment of pig slurry. SENER has developed technology for anaerobic co-digestion of slurries that avoids greenhouse gas emissions when applying the slurry as manure, suppresses the bad odours given off in that process and recovers the renewable energy from the slurries in the form of combustible gas ...

Pig slurry mixed with bulking agent (P+WS) and the solid faction separated from it, both with (PSF+WS) and without bulking agent (PSF), were composted for 13 weeks. Samples for analysis were taken from composting piles at the start of the process and at 3, 6, 9, and 13 …

Air was admitted directly into the centrifugal pump as it was pumping liquid pig slurry. The mass transfer coeff. of oxygen into water (KLa) was measured and then pig slurry used to obtain similar results. The max. gas-liquid mass transfer coeff. (KLa) achieved for the water, pig slurry and separated pig slurry were .0013, .0043 and ..0046 sec ...

Pig slurry is a mixture of farm animal excrements combined with other discharges such as washing water, feed and straw (bedding) losses. When the mixture of water, excreta and various discharges includes at least 85% water, it is considered as slurry.

Abstract BACKGROUND: Manure treatment in intensive livestock farming is required to reduce the risk of negative environmental impacts by nitrogen disposal. Biological removal through intermittent a...

The livestock waste discussed in this paper targets liquid manure or slurry (mix of urine, faeces, and cleaning water, usually with a water percentage of 90% or higher) produced at dairy, pig and poultry farms. The reason of such a targeting is that treatment and application of dry manure is ususally

The wastewater treatment plant (WWTP) investigated operates on an intensive pig fattening farm and is designed for the treatment of 823 m3/d of pig slurry. Before treatment all excrements from pig farm (capacity for 20 000 pigs) accumulate in a collection pit. In the first stage, the solid fraction (SF) of

Pig slurry is produced in massive quantities – more than 930 million cubic metres in the EU alone in 2008. Traditionally, farmers disposed of this mix of urine, faeces and waste water by simply spreading it on the ground as fertiliser. But an increase in intensive farms has left farmers with more manure than they can handle.

Therefore, a simple percolation biofilter for treatment of the liquid effluent was developed. Pig slurry was treated in test-biofilters packed with different biomass for the purpose of selecting the most efficient material, thereafter the efficiency of the biofilter was examined at farm scale with demo biofilters using the most efficient material.

A wastewater treatment system using bamboo groves was assessed for the pig slurry treatment. Three field plots were designed on an agricultural area and planted with 40 bamboo clumps on each plot. A total of 67 m3 of pig slurry was spread on two plots in two forms: raw slurry and centrifuged slurry.

A subsurface flow constructed wetland is used as the main slurry treatment, and the treated slurry is stored in an impermeable pond. In this research, the pig slurry was sampled from two different points; the first one was the raw pig slurry tank, and the second point was the input of the farm's CW, which is the pretreated pig slurry.

Filtration is a simple ecological process for the treatment of effluents. This research examined the physicochemical properties of micronutrients, macronutrients, and heavy metals (HM) removed after the slow filtration of pig slurry (PS) through multiple media: sands, silt loam soils, fly ash, and zeolite. The objective was to find a new layer that can be added to our constructed wetland (CW ...

Treatment significantly (P < 0·01) affected D values with control > ammonia > urea, as did incubation temperature; 4 > 14 > 25°C. Conclusions. Urea and to a lesser extent ammonia may be used to disinfect Salmonella-and/or Y. enterocolitica-contaminated pig slurry, decreasing the storage time required while increasing its fertilizer value.

This paper describes a pilot scale treatment plant that has been designed and built for the thermal inactivation in pig slurry of two viruses that infect pigs--African swine fever virus (ASFV) and swine vesicular disease virus (SVDV). The plant treats pig slurry continuously at a rate of up to 100 l …

"Treatment, ideally directly on the farm, is a truly sustainable solution," says Carsten Tamminga of BD Blue Systems. The company belongs to the Big Dutchman group and focuses its business activities on the question of how pig managers can use their slurry sensibly.

This paper reports the working results from a farm-scale plant of pig slurry treatment built next to a commercial pig farm in which liquid pig manure was treated by a sequential process consisting ...
