  2. Antifreeze - Wikipedia

    en.wikipedia.org/wiki/Antifreeze

    Besides cooling system corrosion, biological fouling also occurs. Once bacterial slime starts to grow, the corrosion rate of the system increases. Maintenance of systems using glycol solution includes regular monitoring of freeze protection, pH, specific gravity, inhibitor level, color, and biological contamination.

  3. Basement waterproofing - Wikipedia

    en.wikipedia.org/wiki/Basement_waterproofing

    The drainage system collects any water entering the basement and drains it to an internally placed sump pump system, which will then pump the water out of the basement. The Federal Emergency Management Agency (FEMA) recommends basement waterproofing with a water alarm and "battery-operated backup pump" as a preventive measure against the high ...

  4. Sump pump - Wikipedia

    en.wikipedia.org/wiki/Sump_pump

    Sump pumps are used where basement flooding may otherwise happen, and to solve dampness where the water table is near or above the foundation of a structure. Sump pumps send water away from a location to any place where it is no longer problematic, such as a municipal storm drain, a dry well, or simply an open-air site downhill from the building (sometimes called "pumping to daylight").

  5. Cold trap - Wikipedia

    en.wikipedia.org/wiki/Cold_trap

    When performed on a larger scale, this technique is called freeze-drying, and the cold trap is referred to as the condenser. Cold traps are also used in cryopump systems to generate hard vacua by condensing the major constituents of the atmosphere (nitrogen, oxygen, carbon dioxide and water) into their liquid or solid forms.

  6. Backflow prevention device - Wikipedia

    en.wikipedia.org/wiki/Backflow_prevention_device

    Backflow prevention device. The simplest, most reliable way to provide backflow prevention is to provide an air gap.An air gap is simply an open vertical space between any device that connects to a plumbing system (like a valve or faucet) and any place where contaminated water can collect or pool.

  7. Ethylene glycol - Wikipedia

    en.wikipedia.org/wiki/Ethylene_glycol

    So, while providing freeze protection and an increased boiling point, ethylene glycol lowers the specific heat capacity of water mixtures relative to pure water. A 1:1 mix by mass has a specific heat capacity of about 3140 J/(kg·°C) (0.75 BTU/(lb·°F)), three quarters that of pure water, thus requiring increased flow rates in same-system ...

    The 122 free-throw attempts were the most in a Division I game since 1996-97 and the 79 personal fouls were the highest in a D-I game since 2017.

  9. Vacuum sewer - Wikipedia

    en.wikipedia.org/wiki/Vacuum_sewer

    vacuum systems are not capable of transporting sewage over very long distances, but can pump long distances from the vacuum station to the next sewage treatment plant or main gravity sewer. vacuum sewerage systems are only capable of the collection of wastewater within a separated system (not for the collection of storm water)
