I want to know how they work. I have not been able to find an article that explains them.
1. Do they have a detector that detects the amount of time they have been installed?
or
2. Do they have a chemical sensor that detects the composition of the filter contents?
or
3. Do they have a sensor that measures the volume of water passing through the filter since
installation?
or do they work in some other way. What triggers the red light to come on.

My well water is highly corrosive. It has destroyed 3 pressure tanks in two years and has caused numerous leaks in the system. I am using a slow sand filter. The well supplies the water used for irrigation on our property too. We consume roughly 15,000 gallons of water a day from that well.
Does anyone know a good system to handle that high a volume of water? Thanks

I heard a news few years ago that a woman died because of drinking too much water during a water drinking contest. So what is the maximum volume of water that a full grown man can drink safely in one sitting?

I’m not looking for numbers. I’m wondering if you placed a penny in a pond, would it displace more water than if you put it in the boat in the pond. I heard that if you put it in a boat because an equal volume of water weighs less than the penny since its displacing gits mass. So which is it?

i want to know the step by step procedure on how to determine the microbial load of a certain water sample (purified water). i want to use the membrane filtration method to do this microbial load determination. i want to know how much volume of water is allowed to pass thru the filter. is it tested undiluted? or do i need to dilute it in a buffer solution? how to compute for the colony forming units (bacteria and molds) found on the filter after the incubation period. how to report the results? what is the allowable count for purified water? can you give any reference or literature for this?
