2. Ozone monitor - Wikipedia

   en.wikipedia.org/wiki/Ozone_monitor

   An ozone monitor of this type operates by pulling an air sample from the atmosphere into the machine with an air pump. [3] During one cycle, the ozone monitor will take one air sample through the air inlet, and scrub the ozone from the air; for the next cycle, an air sample bypasses the scrubber and the ozone value calculated.

3. Portable water purification - Wikipedia

   en.wikipedia.org/wiki/Portable_water_purification

   Portable pump filters are commercially available with ceramic filters that filter 5,000 to 50,000 litres per cartridge, removing pathogens down to the 0.2–0.3 micrometer (μm) range. Some also utilize activated charcoal filtering.

4. Advanced oxidation process - Wikipedia

   en.wikipedia.org/wiki/Advanced_oxidation_process

   These reactive species can be applied in water and can oxidize virtually any compound present in the water matrix, often at a diffusion-controlled reaction speed. Consequently, ·OH reacts unselectively once formed and contaminants will be quickly and efficiently fragmented and converted into small inorganic molecules.

5. Swimming pool sanitation - Wikipedia

   en.wikipedia.org/wiki/Swimming_pool_sanitation

   An electrically operated water pump is the prime motivator in recirculating the water from the pool. Water is forced through a filter and then returned to the pool. Using a water pump by itself is often not sufficient to completely sanitize a pool. Commercial and public pool pumps usually run 24 hours a day for the entire operating season of ...

   The balloon will test changes in aerosols in the stratosphere. One thing scientists, conservationists and researchers are clear on is that solar geoengineering is not a get-out-of-jail card for ...

7. In situ chemical oxidation - Wikipedia

   en.wikipedia.org/wiki/In_situ_chemical_oxidation

   The processes involved with ozonation (treating water with ozone) only leave behind O 2. Ozone can also react with many of the important environmental contaminants. In addition, because ozone is a gas, adding ozone to the bottom of the contaminant pool forces the ozone to rise up through the contaminants and react.
