Indicator material comprising a polymeric gel carrier and polymeric indicator

Indicator material comprising a polymeric gel carrier and polymeric indicator

The invention relates to a polymeric indicator fixed in a polymeric gel carrier, wherein the polymeric gel carrier comprises a hydrophilic polymer, wherein the polymeric indicator and the hydrophilic polymer are present together in the form of a combined cross-linked hydrogel network fixed by chemical bonds.

Waste sorting equipment

Waste sorting equipment

The aim of the present invention is to provide a more cost-effective and space-saving alternative for sorting mixed inorganic waste from household collection into several fractions with less need for high-value industrial equipment than usual. The invention comprises an apparatus (100) for mechanically preselecting separately collected or presorted communal waste, the apparatus comprising: a ballistic separator (110) separating the feed waste into a 2D fraction, a 3D fraction and a fine particulate fraction and producing them as an output stream, and a ballistic separator (110) an optical sorter (120) connected to the output of the ballast separating the incoming 2D fraction into a positive 2D fraction and a 2D residual fraction and producing them as an output stream, wherein the 3D fraction serving output of the ballistic separator (110) and the positive 2D fraction output of the 2D optical sorter at least one of which is connected to a manual sorting unit.

Municipal waste processing equipment

Municipal waste processing equipment

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.

Biofilm carrier

Biofilm carrier

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).

Modified continuous flow sequencing batch reactor and a method for treating waste water

Modified continuous flow sequencing batch reactor and a method for treating waste water

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.
