Research of biological agents effects on reduction of ammonia concentration in stables of intensive farm animals breeding

Abstract

ABSTRACT:In the study are presented results of experiments using bio-technological agents Amalgerol, Bio-Algeen G-40 and BIOSTRONG 510 in intensive pig, poultry breeding and cattle slurry treatment for ammonia emissions reduction. The measuring was conducted, suggested and verified by continual method through the measuring station ASECO and instrument 1312 Photoacoustic Multi-gas Monitor of firm INNOVA Air Tech Instruments. The reached results confirm unambiguously possibility to reduce ammonia emissions from farm animals breeding. ; CO 2 ± 3.4 mg/m 3 ; COMMETER 03121, temperature ± 0.21°C; humidity ± 1.8%. Keywords Method with utilisation of photo-acoustic spectroscopy (FAS)For measuring of ammonia concentration will be used the device 1312 Photo-acoustic Multi-gas Monitor of firm INNOVA Air Tech Instruments with multi-channel sampling and portioning system 1309.The principle of measurement is based on absorption of infrared light passing through the sample of gas. The photo-acoustic method measures directly the amount of absorbed light energy by measuring the acoustic energy radiated by the gas molecule before this has absorbed the light. The measured signal evaluation is conducted by means of appropriate software, processed and recorded. The apparatus enables to measure simultaneously in one site up to 5 gases and water vapour.At the end of 2003 this method was approved by the Czech Inspection for Environment and by Ministry of Environment of the Czech Republic for authorised measuring of ammonia emissions. The withdrawing sites layoutThe withdrawing site layout has a significant effect on objectivity of measured values. In prevailing amount of new or modernised stables for pigs and poultry breeding is used the forced ventilation. For measuring of ammonia concentration with respect to environment loading we choose the withdrawing site as close as possible to the output fans or slots in dependence on type of ventilation (negative pressure or positive pressure), where ammonia concentration in stable is highest, but not just in the flow of the drawn off air.For measuring and analysis of quantities is necessary to distribute measuring to some sites.The withdrawal sites in stable are placed:In zone of animals, i.e. in part of stable reserved between floor and height of staying animal or cage ceiling;In zone of operators, i. e. in part of stable determined for motion of operators providing basic maintenance of technology, poultry, treatment, veterinary control etc. Measuring is conducted in the respiration zone of standing man.In zone of ventilation, i.e. in space where ammonia emissions leave into atmosphere. Mostly it concerns measuring on drawing off ventilators. Measuring is significant for determination and verification of emission factor in framework of emission amount announcement into integrated register of pollution. METHOD OF MEASURED RESULTS EVALUATION AND CALCULATION RELATIONS Calculation of pollutant concentrationFor calculations are used relating conditions, when humidity, temperature and static press...

Possibility of reduction of ammonia emissions from manure storage piles

“…It causes a significant limitation of current emissions -up to by 40-68%. Through the practical verification, its declared activity and effectiveness was confirmed by the utilization in our country (JELÍNEK et al 2004;NÁVAROVÁ 2001) and abroad (GJORDSLEV 1992).…”

“…These are in addition completed by a component of paraffin distillates of the pharmaceutical quality class. Amalgerol Classic stimulates development of microbial strains participating in biodegradable processes and simultaneously consumes products of this decomposition for cellular tissues of own strain within the process of rapid multiplication (JELÍNEK et al 2004). It causes a significant limitation of current emissions -up to by 40-68%.…”

Through the practical verification, its declared activity and effectiveness was confirmed by the utilization in our country (JELÍNEK et al 2004;NÁVAROVÁ 2001) and abroad (GJORDSLEV 1992).Before the loading of broilers, the bedding in the broiler shed was treated with the 3% solution of Amalgerol Stall Max FL in a dose of 0.25 dm 3 per 1 m 2 of the bedding surface. Amalgerol Stall Max FL is a biotechnological agent with disinfection and desinsection properties and was used instead of common desinfection and desinsection chemicalbased agents.…”

“…According to the Protocol an advisory code of Good agricultural practice needs to be established, published and disseminated taking into account the specific conditions within the specific territory and shall include provisions on: -Nitrogen management, involving the whole nitrogen cycle; (JELÍNEK et al 2004). Good agricultural practice resulting from the Czech legislation concerning atmosphere protection is based on the principle of ammonia abatement technologies.…”

“…The application of biotechnological agents is one of the verified ammonia abatement technologies that could be used in the housing systems. These agents, when properly used, provably and significantly reduce ammonia emissions by certain percentage in comparison with reference technologies commonly used in the housing systems (JELÍNEK et al 2004). The goal of this survey was to verify the reducing effect of the biotechnological agents on the ammonia emissions from pig and broiler farmyard manure storage piles.…”
