    Analysis of poultry manure utilisation methods to produce organic fertiliser
    (Lviv Politechnic Publishing House, 2018-02-26) Malovanyy, Myroslav; Odnorih, Zoryana; Kanda, Mariya; Lviv Polytechnic National University
    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.

    Determination of an impact of the composition on the pH level and the concentration of ammonium nitrogen in soil of Pustomyty distrаct, Lviv region
    (Publishing House of Lviv Polytechnic National University, 2017) Кanda, Maria; Malovanyy, Myroslav; Оdnorih, Zoryana; Lviv Polytechnic National University
    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.

    Integrated adsorption and ultrasonic technology for water treatment processes
    (Publishing House of Lviv Polytechnic National University, 2016) Vronska, Nataliya; Malovanyy, Myroslav; Koval, Iryna; Starchevskyy, Volodymyr
    The aim of this work is to study the process of water purification from mechanical and chemical pollution and pathogenic microflora by adsorption and ultrasonic methods. Proposed technology reduces bacterial contamination and purifies water from organic pollutants, improving its quality.
