I'm interested in buying a property that's listed as having well water and I was wondering which system could sanitize the water to city water standards?"
Thanks for emailing. For your application we recommend a Chlorinator, Contact Tank and Carbon Filter. The chlorinator will automatically inject a small amount of chlorine, and the water will be sanitized just like city water.
Chlorination and the Stenner Pump Chlorinator System
Chlorine is a low cost and safe method of eliminating odors and bacteria, and it works great in oxidizing iron, manganese and other contaminants in water so they can be filtered out.
Although there are other ways to eliminate microorganisms and odors in water, chlorination is the most commonly used because it is low cost and effective. Often combined with filtration, chlorination is an excellent and cost-effective way to disinfect drinking water supplies, eliminate odors, and oxidize iron, and other metals.
For easy and accurate chlorine injection we recommend a Stenner Pump and solution tank system. The Stenner pump uses liquid chlorine bleach. The system is reliable, easy to install, very easy to use. It can be adjusted to get just the right amount of chlorine needed for the application.
The chlorinator can be adjusted so the chlorine levels are very low in the household (similar to city water) or a low cost carbon filter can be installed to remove any trace of chlorine tastes and odors.
Contact provides optimal contact time after chlorine, soda ash, peroxide or other water treatment grade chemicals have been injected into the water. By using a contact tank, the amount of solution needed is less and insures that the solution being injected is thoroughly mixed and dissolved in the water.
These WellMate Contact Tanks are made of a seamless inner shell of molded polyethylene and are impact and corrosion resistant. The tanks are high quality NSF/ANSI 61 certified tanks for drinking water. Inlet and outlet connections are 1-1/4” but can be reduced to 1” or ¾” if needed.
Carbon Backwash Filter Systems
Our Carbon Backwash Filter Systems remove chlorine, tastes, and odors at exceptionally high flow rates with little or no pressure drop. Unlike expensive carbon filter cartridges, the Carbon Backwash Filter Systems use a bed of high grade activated carbon to filter out chlorine, chemicals and sediment. With these systems the carbon is backwashed and rinsed clean automatically, meaning there's no need to change short-lived filter cartridges, and no problems with pressure drop from clogged filters. The carbon media typically lasts for 3 - 5 years and is easy to dump out and change. Save hundreds of dollars over expensive filter cartridges and enjoy great flow rates with little or no maintenance required.
Here is a diagram of a typical installation. These systems are designed to be easily installed by any plumber or person familiar with basic plumbing:
Metering Pump & Tank: 45MHP-10 Stenner Pump with 15 gallon heavy-duty polyethylene solution tank; Pump output 0.5 to 10.0 gallons per day (1.9 to 37.9 liters per day); voltage 115 or 220V; 60 Hz. This is a complete system that comes with everything you need: solution tank; metering pump; tubing; fittings; and injection check valve.
Contact mixing pressure tank 40 gallon
Dimensions 16" diameter x 53" height
Gives contact time to allow chlorine to properly treat the water.
Carbon 7000-SXT 1.5 CF
Excellent for use in dechlorinating water and removing many tastes and odors. Unlike carbon cartridges which can trap sediment and dirt causing pressure drop these systems automatically backwash out trapped sediment alleviating pressure drop. Fleck 7000 control provides high flow with very little pressure drop.
