Whole House Iron Filter
Iron is one of the most common elements found in nature. Staining problems occur in waters that contain as little as 0.3 ppm (parts per million) iron. Iron is found in several forms, the most common of which are Ferrous (Fe++) and Ferric (Fe+++) iron. Ferrous iron is colorless in solution, but when it comes in contact with air, it oxidizes readily, creating red solid particles which are easily filtered from the water. 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 an ion exchange process is used. 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.
Whole House Activated Carbon 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.
Reduction of:
- • Chlorine
• Chlorine By-products- Trihalomethanes (THMs):
A group of organic chemicals, suspected of being carcinogenic.
• Bad Tastes & Odors
• Toxicity
• Herbicides, Pesticides, & Insecticides
• Volatile Organic Chemicals (VOCs): Organic chemicals that turn into vapor.
The Ozone Process Works In Three Easy Steps
1) Ozone Injection/Oxidation:
Ozone is a tri-atomic oxygen (O3) which has a very high oxidizing power. It is a gas produced from air and high voltage electricity. The ozone is injected into the water. At this point oxidation of iron, sulfur and manganese is immediate.
2) Aeration:
The elimination (off gassing or venting) of the ozone and other gasses/odors such as sulfur occurs by an ozone stripping action. As water flows down the Off Gas Tank, ozonated water rises and strips gases from the incoming water.
3) Filtration:
The final step for removing the oxidized material is filtration. Formulated in 1988, SPS10 Is a natural physical filter media requiring only water for backwash. No chemicals or oxidizing media is necessary. SPS10 is non-porous and inert. It yields a high flow and requires a low backwash rate.
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 Neutralizing system. This system 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 6.0 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.
