This article provides an overview of the poultry manure utilisation issues. It gives a comparative analysis of the methods of composting and vermiculation, production of organic-mineral fertilisers, granulation and thermal drying of the output raw product. Integrated combination of granulation and thermal drying is considered to be the most efficient in the poultry manure processing technology.
The influence of the power of ultrahigh-frequency electromagnetic radiation on the
degree of dehydration of a natural sorbent – clinoptilolite was investigated. It is established
that there is a certain threshold value of radiation power, in which dehydration of clinoptilolite
occurs. It was established that clinoptilolite activated in the electromagnetic field has a higher
than unactivated sorption ability for compounds of different nature, in particular, sulfur(IV)
oxide and formaldehyde
The results of research of the chemical activation process of clinoptilolite from Sokirnytskyi field are shown. As a result of the research, the effectiveness of the influence on zeolite hydrochloric and sulfuric acids are compared. It should be noted that the advantage is on the side of hydrochloric acid. It was established that the increase in the concentration of sulfuric acid and the time of zeolite processing leads only to the increase in the content of the amorphous phase.
This research involves studying the application of palygorskite from Dashukivka Deposit and clinoptilolite from Sokyrnytsia Deposit in production of organic fertilizers prolonged. It is found that maximum ammonia sorption capacity is 1.56・~10-2 mg-eq/g of sorbents. The composition proposed has a positive impact on condition of the studied soils. The pH level of soil solution shifts toward neutral, and the level of ammonium nitrogen is uniform throughout 24 days.
The adsorption properties of Transcarpathian clinoptilolite regarding Cr (VI) ions is studied. It was found that the adsorption isotherm has s-like form and belongs to the isotherm of type II. It is established that the adsorption proceeds further after the formation of monomolecular adsorption layer. It leads to the cteation of dimolecular layer. Вивчено адсорбційні властивості закарпатського клиноптилоліту стосовно іонів Cr (VI). З’ясовано, що ізотерма адсорбції має s-подібний вигляд і належить до ізотерми ІІ типу.
In the present paper the sorption of petroleum substances such as diesel fuels on zeolite beds was investigated. A natural occurring zeolite clinoptilolite, and mixtures of clinoptilolite and synthetic zeolites Na-P1 and Na-X type, in the ratio 3:1, were used in this study. Natural zeolite acquired from the mine tuffs in Sokyrnytsya (Ukraine). In order to obtain synthetic zeolites, F-class fly ash (Kozienice Power Plant, Poland) with sodium hydroxide was used and later it underwent the hydrothermal conversion.
