Compressed Air Energy Storage (CAES) plants are largely equivalent to pumped-hydro power plants in terms of their applications, output and storage capacity. But, instead of pumping water from a lower to an upper pond during periods of excess power, in a CAES plant, ambient air is compressed and stored under pressure in an underground cavern. When electricity is required, the pressurized air is heated and expanded in an expansion turbine driving a generator for power production.

This video helps you select the correct style Harmsco liquid filtration cartridge for your specific application.

Before you can determine what type of filter you will need, you need to identify what type of contaminates you are removing:

  • Is it a tiny particulate or a large solid?
  • Is it hard, fibrous, gelatinous?
  • Is it a liquid such as a solvent, oil, or ink?

The three main filter types are:

  • Depth Filters work best on liquid contaminates such as gels, solvents, ink and oils.
  • Bag Filters designed to work best with large contaminates.
  • Pleated Filters are most efficient for filtering particulates.

Harmsco Filter Types

Remember: a low-cost filter that needs frequent replacement costs more to use than a higher-cost filter that rarely needs to be changed.

Great info about disinfecting your private well from etrlabs.com:

Well disinfection can eliminate or reduce many different kinds of harmful bacteria (germs, viruses and microorganisms), as well as non-harmful bacteria that can cause unpleasant tastes or odors. A change in your water’s taste, color or smell may not always be a health concern, but it could be a sign of serious contamination problems. You should disinfect when:

  • Coliform bacteria are present
  • After flooding of a well
  • After plumbing installation or changes
  • After casing or pump repairs
  • During the start up of seasonal wells
  • When taste changes or odors are present
  • As part of annual well maintenance

Unfortunately, many people use the wrong disinfecting agent and may do more harm than good to their water supply and their health. Laundry bleach should not be used for disinfecting a well, it should be used for laundry purposes only, that is what is was created for. This type of bleach is not pure and may contain harmful toxins which is why you can not drink or bathe with the water while it is in your well water system. Routine chemical disinfection is critical to maintaining a safe private water supply. Why not use a safe product specifically designed to treat well water.
