Study of the effectiveness of the small municipal sourcess sewage sludge extensive stabilization for their use as a fertilizer
The article is devoted to the presentation of partial results of a study aimed at determining the potential use of extensive sludge dewatering technology for small municipal WWTPs (up to 1000 PE) in the conditions of the Czech Republic. The study has shown that the use of technology based on extensive sludge dewatering and their stabilization in sludge dewatering reed beds with suitable wetland vegetation can be an alternative to other technologies. Especially in combination with constructed wetland (CW) based WWTPs, which are characterized by lower sludge production.
Fidings from testing of selected biochemical products to the heritage sites water elements environment adjustment
The article is focus on the presentation of knowledge from testing of selected biochemical preparations for the treatment of the environment of water elements of historical gardens and parks and cultural monuments.
Water elements represent a significant part of the environment of cultural heritage sites, conservation zones and areas. To fulfil the required functions, which may include social, historical, recreational and educational, but also environmental functions; it is necessary to ensure their corresponding target state.
Potential of the nature-friendly measures application for water retention in the landscape and improvement of the ecological status of water bodies
An analysis and assessment of the nature-friendly measures potential for water retention in the landscape were carried out as a part of the work on the concept of protection against drought impacts in the Czech Republic.
Non-invasive and economical techniques of water elements environment quality and maintenance solution in the frame of historical monuments care – presentation of the project
The research team from the Brno office of WRI and reference laboratories in Prague started from March 2016 work on a research project DG16P02M032 “Non-invasive and economical techniques of water elements environment quality and maintenance solution in the frame of historical monuments care”.
Horizontal and vertical flow constructed wetlands belong among frequently used near-natural methods of treatment of wastewater from small municipalities in the Czech Republic. They consist of one or more filter fields connected in series or in parallel.
Small water reservoirs are one of the principal elements of agricultural landscape in the Central European context. The monitoring of the quality of aquatic environment of selected ponds and small reservoirs (SWR) in areas of southern and central Moravia and the Vysočina Region was carried out in 2013 to 2015.
Quality of sludges and wastes from household and small wastewater treatment plants and their utilization in agriculture management
The aim of this article is to introduce partial sections of the research projects TA02020128 and TA02021032 (Technology Agency of the Czech Republic). These parts of the projects pay attention to the issue of quality of sludge and other wastes produced in wastewater treatment plants (WWTP) using activated sludge process, anaerobic processes (including septics) and extensive (natural) wastewater treatment plants (with horizontal subsurface flow reed-beds), which also include mechanical pre-treatment.
