Water Treatment can treat all types of problems and concerns:

Advanced Plumbing of Connecticut - WaterHard water is water that has high mineral content (in contrast with “soft water”). Hard water is generally not harmful to one’s health, but can pose serious problems in industrial settings, where water hardness is monitored to avoid costly breakdowns in boilers, cooling towers, and other equipment that handles water. In domestic settings, hard water is often indicated by a lack of suds formation when soap is agitated in water. Wherever water hardness is a concern, water softening is commonly used to reduce hard water’s adverse effects.
Advanced Plumbing of Connecticut - WaterAcidic water can be corrected by several water treatment strategies. A common treatment is injection of soda ash, and a more aggressive treatment is the injection of caustic soda (sodium hydroxide). This is usually accomplished by injecting a solution of the soda ash or caustic soda directly into the water pipe.

A second strategy is to run the water through a bed of calcite (the most common treatment mineral) or corosex. As the low pH water passes through the bed, the mineral dissolves into the water and raises its pH.

Calcite treatment raises the pH by adding calcium carbonate to the water. This has the sometimes undesirable effect of increasing the hardness of the water slightly. Calcite and corosex are most commonly used in backwashing filters, but calcite alone can be used with simple upflow filters if the water is reasonably clean. Calcite is also commonly used in cartridge form as a postfiltration treatment for undersink reverse osmosis units. RO lowers pH, and calcite filters are used to bring the pH back to neutral.

Advanced Plumbing of Connecticut - Water Under the right conditions, ferrous iron can be removed by ion exchange (a water softener) or by oxidizing it to ferric iron then removing it with mechanical filtration. Ferrous iron “can be removed with a softener provided it is less that 0.5 ppm for each grain of hardness and the pH of the water is greater than 6.8.” (The Enting Corporation Engineering Handbook. Not everyone would agree.) Generally, it is accepted that about 5 ppm fe is the upper limit for removal with a water softener. Ferrous iron is most commonly removed by oxidation (with air, ozone, potassium permanganate, chorine, or hydrogen peroxide) and filtration. This is a tricky process at times and different filter media are pH dependent at different levels. Some media (Filox, Birm, Greensand) can act as both oxidizer and filter if conditions (pH and dissolved oxygen, for example) are right.

Ferric iron cannot be removed by a water softener, but it can be removed readily by filtration–even with a simple wound string filter, although backwashing filters are most commonly used because iron stops up conventional sediment filters quickly unless the amount is very small.

Heme iron can be removed by a scavenger anion resin or by oxidation with chlorine followed by mechanical filtration.

When iron bacteria are present, the standard treatment is chlorination followed by filtration.

Advanced Plumbing of Connecticut - WaterPathogenic bacteria are treated in a variety of ways. Chemical oxidation is the most common. The most frequently used chemical is chlorine, but chloramine (a mixture of chlorine and ammonia) is gaining in popularity. Ozone is another powerful chemical oxidizer used to disinfect water.

Bacteria can also be removed by filtration. Submicron filters are excellent bacteria removers. In fact, ceramic filters, made by the world’s oldest water filter company, were initially developed to remove bacteria from the polluted waters of the Thames. Filters that are classed as microfilters and ultrafilters are effective against bacteria, as is reverse osmosis, though manufacturers of reverse osmosis do not normally claim bacteria removal as a function of their products.

Ultraviolet light is another standard defense against pathogenic bacteria. UV is actually classified as a sterilizer because it works by disabling the microbes’ ability to reproduce.

Advanced Plumbing of Connecticut - WaterActivated carbon adsorption is the most standard approach to taste/odor improvement. Oxidation/reduction is also used. Chlorine is only partially effect for odor improvement, and chloramine is not effective at all. Chlorine dioxide and ozone are excellent oxidizers for odor improvement. Hydrogen peroxide is very effective against hydrogen sulfide.

“Activated carbon has an excellent history of success in treating taste and odor problems. The life of the carbon depends on the presence of organics competing for sites and the concentration of the odor causing compound.” — Enting Engineering Handbook.

Advanced Plumbing of Connecticut - WaterTaste and odor problems in water are often considered together. Many taste/odor issues are related to the disinfectants used in water treatment.

Other causes are mineral contaminants, for example:

Chlorides in excess of 500 ppm produce a “salty” taste.

Blue green algae, depending on its quantity, can cause “grassy” and “musty” tastes and odors, as well as a “spicy” odor. Algae is also blamed for “fishy, rotten, septic, and medicinal” odors.

Hydrogen sulfide gas causes what is commonly called a “rotten egg smell.”

Rotting vegetation is probably the most common cause of taste/odor problems, however.

Advanced Plumbing of Connecticut - WaterActivated carbon is the most commonly used color reducer. Anion exchange (usually following a water softener) is a common treatment for tannins, and certain types of macropore carbon are also effective at tannin removal. Iron and manganese coloration are treated in the standard ways that iron and manganese are treated. See sections on iron, manganese and copper for methods of reducing these contaminants and consequently the color alterations that they cause.
Advanced Plumbing of Connecticut - WaterSediment, a naturally occurring material that is broken down by processes of weathering and erosion, and is subsequently transported by the action of wind, water, or ice, and/or by the force of gravity acting on the particle itself.

Sediments are most often transported by water (fluvial processes), wind (aeolian processes) and glaciers. Beach sands and river channel deposits are examples of fluvial transport and deposition, though sediment also often settles out of slow-moving or standing water in lakes and ocean dunes and loess are examples of aeolian transport and deposition. Glacial moraine deposits and till are ice-transported sediments.

Advanced Plumbing of Connecticut - WaterRadon can be removed from water by using one of two methods: aeration treatment or granular activated carbon (GAC) treatment.

Aeration treatment involves spraying water or mixing it with air, and then venting the air from the water before use.

GAC treatment filters water through carbon. Radon attaches to the carbon and leaves the water free of radon. The carbon may need special handling in its disposal if it is used at a high radon level or if it has been used for a long time.

In either treatment, it is important to treat the water where it enters your home (point-of-entry device) so that all the water will be treated.

Advanced Plumbing of Connecticut - WaterRusty water occurs from sediment in the pipes or rust from the inside walls of the water mains.The rust can be disturbed and temporarily suspended in water with unusual water flows from water main breaks or maintenance or by flushing of a hydrant. This discolored water is not a health threat. When the water is discolored it is recommended to either not wash laundry or to use a rust stain remover or regular detergent but not chlorine bleach as it will react with the iron to form a permanent stain.

The other major cause of brown, red, orange or yellow water is rusty water pipes in your building. If old, rusty pipes are discoloring your water, consult a licensed of plumbing materials or an experienced plumber. Water that is being discolored by rusty pipes is not a health hazard; however, it is an indication that the pipes are corroding and they can eventually leak.

Advanced Plumbing of Connecticut - WaterCalcium is readily removed from water by a simple sodium form ion exchanger, commonly known as a water softener. Reverse osmosis removes 95% to 98%, but removal of hardness usually causes scaling of RO membranes. Calcium can also be removed by deionizers (hydrogen form cation exchangers), dialysis, distillation and ultrafiltration.
