WHOLE HOUSE/POINT OF ENTRY
Whole House Activated Carbon Water Filters/Auto Backwash Systems
Our whole house Auto Backwash Activated Carbon Water Filter connects to the main line of your home and filters all your home's incoming water, including water that runs through your shower and bath. The whole house activated carbon water filter is the perfect companion for a water softener system and it may be installed in municipal or well water. The activated carbon filter may be used after chlorination of your well or air injection treatment. The activated carbon filter is the final touch in any water application. It provides reduction of:
- Chlorine
- Chlorine By-products- Trihalomethanes (THMs): A group of organic chemicals, suspected of being carcinogenic.
- Bad Tastes and Odors
- Toxicity
- Herbicides, Pesticides and Insecticides
- Volatile Organic Chemicals (VOCs): Organic chemicals that turn into vapor
Whole House Iron Filter
Iron is one of the most common elements found in nature. Well waters can have iron content as little as 0.1 ppm up to 50 ppm or more. Problems like staining start occurring in waters that contain 0.3 ppm. Iron can also be found in several different forms. Ferrous and Ferric iron are the most common. Ferrous iron is colorless in solution, but when it comes in contact with air, it oxidizes readily, creating red solid particles which are known as Ferric iron. With the iron in Ferric form, the task of removing it from the water is then easily achieved.
The process of converting Ferrous iron to Ferric iron is dependent upon several factors. The most important factor for effective iron removal is the pH level of the water. The pH level strongly dictates which approach to take regarding the removal of iron. Higher pH levels are more favorable for effectively oxidizing the iron. A pH level of 6.8 or higher is desirable. Low pH waters can also be effectively treated for iron removal, but the process becomes a little more involving.
Watertech, Inc. has several options available for iron removal. A water analysis to determine the other water parameters is necessary to assure the correct system is applied.
pH Neutralizer Systems
pH neutral water should be within the 7.0 to 7.8 range. The easiest and most common way to resolve low pH problems is with the use of an Automatic Backwashing Neutralizer system. Backwashing neutralizer contains calcite (calcium carbonate) and magnesium oxide that slowly dissolves to correct pH. For applications with extremely high TDS, a chemical injection system can be used to inject soda ash solution into water to correct low pH.
Selecting the correct type of neutralizer for your specific application is very important. Generally, backwashing neutralizer can be used for most applications with water pH in the range 6.4 and above and a TDS of less than 150. Strong Acid Neutralizers with a 5:1 calcite/magnesium oxide mix are used in lower pH or high TDS conditions. We might recommend a higher calcite/magnesium oxide mix ratio for some applications. In some cases, our customers install a Water Softener downstream of a backwashing neutralizer to remove any hardness from their water.
You may want to consider a Chemical Injection System if your water contains a very high TDS level. This is because with an already large amount of dissolved solids contained in your water, it may not be possible for standard neutralizer media to have sufficient contact time to neutralize your pH. In this case, a soda ash solution chemical injection system is recommended. A soda ash injection system does not add any additional hardness to your water.
