Abstract: The invention relates to a storm water filtration system comprising: (i) a storm water drain pit (12); (ii) a filtering well (1) for filtering storm water; (iii) a storm water collection system (7) for storing filtered storm water: wherein the filtering well comprises: an inlet (2) for storm water to enter the filtering well; wherein the inlet (2) is in fluid communication with the storm water drain pit; an outlet (3) for filtered storm water to exit the filtering well; wherein the outlet (3) is in fluid communication with the storm water collection system (7); a filter (4) comprising man-made vitreous fibres (MMVF) for removing particles from the storm water, wherein the filter (4) divides the filtering well (1) into an inlet chamber (5) and an outlet chamber (6) such that storm water enters via the inlet (2) into the inlet chamber (5), passes through the filter (4) into the outlet chamber (6) and exits via the outlet (3). The invention also relates to a method of filtering and storing storm water using a storm water filtration system as described herein and a method of installing a storm water filtration system as described herein.

Abstract: The invention relates to a method of preparing a mineral melt in a cupola furnace that uses at least one plasma torch to provide heat energy to the furnace. The plasma torch uses nitrogen, carbon monoxide, carbon dioxide, or a mixture thereof as the carrier gas. The invention also relates to a cupola furnace for the preparation of the mineral melt, and the use of a plasma torch in a cupola furnace to reduce the amount of NOx and/or hydrogen in the furnace off-gas.
