Study and Research on Cleaning Procedures of Anaerobic Digestion Products / Studium A Výzkum Postupů Čištění Anaerobní Digesce


This paper focuses on increasing quantities of digestate, a final product of anaerobic digestion, in biogas stations being built as alternative sources of energy. The potential use of digestate is limited due to its rather specific physical properties. This paper presents current approaches to digestate and digestate management. The objective is to compare the properties of digestate and the products of its separation via centrifuging, i.e. the liquid phase known as digestate liquor, and the solid phase referred to as digestate fibre. Its focus is mainly laid on techniques for dewatering digestate in low-solid anaerobic processes only, which have been tested for the effectiveness of the basic physical and chemical methods including their combinations. The measured results show that the use of coagulants and flocculants for this purpose would be very problematic in practice with regard to their high consumption as well as the need to input other elements into the process.

Predicting the vessel lumen area tree-ring parameter of Quercus robur with linear and nonlinear machine learning algorithms

regression by using linear spline regression and a likelihood-based model to explain nonlinearity in the relationship between tree rings and precipitation. One of the most accurate and tested process-based models, the Vaganov-Shaskin model ( VS model, Shishov et al ., 2016 ; Vaganov et al ., 2011 ), uses a piecewise linear function to model the relationship between daily environmental data and tree-rings. A similar idea is implemented in a simplified version of the VS model – the VS-Lite model ( Tolwinski-Ward et al ., 2011 ). The advantages of using nonlinear models
