A compact lightweight air filtration system is disclosed. The air filtration system includes a hydrophobic particulate/coalescing filter and a cleanable ozone converter housed in a housing with an inlet and an outlet. Air flowing from the inlet to the outlet passes through the particulate/coalescing filter element and then the cleanable ozone converter to remove particulates, aerosols, liquids, and ozone.

Provided is an ion wind generation device which is capable of providing a wide range of ion delivery and providing ion wind having a reduced ozone concentration near a nozzle without use of a filter or the like.

The ion wind generation device includes an electrode pair including a discharge electrode body having a discharge portion and a counter electrode body having a plurality of end portions, and generates ion wind by corona discharge that occurs due to a potential difference generated between the discharge portion and the end portions. The end portions are located spaced apart from one another in a single plane and disposed around an axis of the discharge electrode body in the single plane or disposed along a line in the single plane.

An apparatus for corona treatment, the apparatus including a corona treatment unit with an inlet side and an outlet side, wherein the unit includes one or more sets of transverse electrodes, at least one electrode in each set being connected to a high voltage source and at least one second electrode connected electrically to ground, wherein the second electrode connected to ground includes a rotatable roller. The apparatus is a through-flow apparatus adapted for corona treatment of material in sheets, and including at least one conveying table with a transverse direction and a longitudinal direction, where the at least one conveying table includes mechanical conveyor means. By such a solution is achieved an apparatus through which sheets of material can be conveyed and corona-treated without holding the material and pulling it through the apparatus.

Surface-oxygenated biochar compositions and sonication-ozonization methods create advanced hydrophilic biochar materials having higher cation exchange capacity, optimized pH, improved wettability, and toxin free components. These sonicated and ozonized biochar compositions are used as filtration materials for clean water and air, as phosphorus solubilizing reagents to mix with phosphate rock materials to make a slow-releasing phosphate fertilizer, as biochar soil additives to help solubilize phosphorus and reduce phosphorus fertilizer additions required to achieve desired soil phosphorus activity, crop uptake, and yield goals, as sand soilization reagents by utilizing their liquid gel-forming activity in the spaces among sand particles to retain water and nutrients and hold the sand particles together, as plant growth stimulants by using the humic acids-like surface-oxygenated biochar substances at a proper ppm concentration and as carbon sequestration agents to help control climate change for energy and environmental sustainability on Earth.
