The present invention relates to an apparatus which makes the fine-grain fraction, generated during the waste treatment processes of producing fuel from municipal waste, suitable for further utilization in biogas plants as a valuable organic matter.
This invention relates to a biofilm carrier made of structured yarns (1) comprising filaments (2), where each individual filament (2) constituting the central yarn (1) forms a continuous fibre running over the entire length of the yarn (1) and filaments (2) are fixed to each other by anchor points (3) along the length of the yarn (1), and structured yarns (1) are fixed at fixing points (5) of a mesh structure (6), and each structured yarn (1) forms a loop (4) between two adjacent fixing points (5), the arc length (T) of which is greater than the distance (t) of the two fixing points (5).
The present invention relates to a method for treating municipal and industrial waste water performed in a sequential batch reactor (SBR) system, where the biological oxidation, nitrification, denitrification, phosphorous removal processes and solid separation takes place in one or multiple treatment basin(s), and more particularly to a process performed in a sequencing batch reactor (SBR) system for efficiently removing phosphorous from waste water treated. The invention also relates to an apparatus to perform the method according to the invention.
Arrangement for adjusting the soil moisture of a sports field, the structure (S) of which contains a field surface (P), a tread layer (9) below the field surface (P), and a support layer (T) formed below the tread layer (9), and the tread layer (9) is separated from the support layer (T) by a separating layer (V), a network of drainage pipes (6) is arranged in the support layer (T) and connected to a pool (M), and the support layer (T) is lying on a waterproof film (4). The basin (M) is provided with a filling valve (26) and a sluice opening (13) the lower flow level (A) of the latter is arranged below the upper level of lower crushed stone layer (A).
The present invention relates to a process for the composting of solid, organic solvent-free herbal residues left over from steam distillation / hydrodistillation; and to the production of stable, mature compost containing reduced levels of pathogenic microorganisms and of phytotoxic substances.
