Nanoporous activated carbons were prepared by hydropyrolysis processing from various biomass precursors – apricot stones, been pods, bamboo, etc. The obtained carbon adsorbents are distinguished with moderately high surface area and prevailing microporous structure. Their properties determine their application as effective adsorbents for removal of organic (phenols, etc.) and inorganic pollutants (metal ions, etc.).

The purpose of this report is to propose possible engineering solutions for the construction, reconstruction and modernization of the existing irrigation infrastructure in our country . These solutions can assist beneficiaries in the application process for the Rural Development Program 2014-2020 under sub-measure M4.3 "Support for investment in infrastructure related to the development, modernization or adaptation of agriculture and forestry". In order to achieve this goal, the state of the existing irrigation infrastructure has been analyzed and the specifics of the irrigation systems in our country have been assessed. Based on this several model systems of different type and construction were selected. For some of the irrigation fields, possible technical solutions concerning their completion, reconstruction and modernization have been analyzed.
The poor technical condition of the existing irrigation infrastructure in our country and “Common Strategy for Management and Development of Hydro melioration and Protection against Harmful Effects of Water”, which was prepared by a World Bank, give us reason to expect the financing of projects for the rehabilitation and modernization of irrigation systems. Analyzed good practice in this area shows that project management is essential to the qualitative and effective achievement of the main goal. In the report, special attention has been paid to the process of planning certain priority projects for the rehabilitation and reconstruction of irrigation infrastructure at the construction stage and an analysis has been carried out for the different areas of management (time, costs, quality, human resources, communications, supplies and risks).
