Chlorination Systems

Chlorination Systems are a very useful and practical way to handle a wide variety of water quality problems.  Chlorine is an oxidant, meaning it can chemically change the molecular structure of many impurities. Oftentimes, the molecular structure of the newly formed impurity is easier to remove from the water supply. An excellent example of the oxidation process is the oxidation of iron.  When chlorine in water interacts with dissolved iron, it alters it from a ferrous (fe+2) to a ferric (fe+3) state.  The ferrous iron, sometimes called a clear water iron, cannot be easily filtered out of water; however, the ferric iron, sometimes called red water iron can be easily filtered out.  Other impurities in the water are also affected by the oxidation principle of chlorine.

Additionally, chlorine is a powerful disinfectant, able to kill bacteria, viruses, and many other micro-organisms.  This tactic has been used for over 100 years.  Virtually all municipally treated water has chlorine added, often in a couple of different phases of the treatment process.  Although very effective for bacteria and viruses, there are some micro-organisms such as cryptosporidium and giardia that are not effectively destroyed by chlorination.

Although chlorine does have some wonderful properties, it also has some negative characteristics.  Chlorine will combine with certain organics in a water supply and create other organic compounds.  One set of these organic compounds is known as Trihalomethanes, which have been linked with the occurrence of cancer. Another negative of chlorinated water (especially in high doses) is that the water is more aggressive towards piping, valves, faucets, and other plumbing fixtures.  Finally, many consider chlorinated water to have an objectionable smell.

But there is good news: the three negative characteristics of chlorinated water are virtually eliminated on a GW Pumps & Purification chlorination system. Although these negative characteristics exist after the chlorinator and retention tank, the water is sent through a de-chlorination filter before going into the plumbing system. The GW de-chlorination filter has been designed to remove oxidized iron, trihalomethanes, chlorine, and many other impurities.

There are many components involved in a typical Chlorination system.  The following is a listing of the components and a short description of the purpose of the component.

(A) Well – The water source
(B) Well Pump – The pump that provides water flow and pressure to the plumbing system.
(C) Sample Port – A hose bib or other valve that is installed to test the water quality. It is important to have a sample port prior to any water treatment equipment to test the untreated water at this point.
(D) Injector Fitting – This is a special fitting that has been designed to handle the corrosive chlorine and to prevent water from the pressurized pipe from flowing backwards into the chlorinator and/or solution tank.
(E) Chemical feed pump – This is the pump that creates high pressure and low flow. Depending on the model, some of these pumps, flow as low as 1/4 ounce per minute.
(F) Solution Tank – This tank is a non-pressurized tank that holds a mixture of liquid chlorine and purified water. In some cases straight liquid chlorine is used. Upon installation of your system, one of GW’s water experts will provide the proper mixture for your tank.
(G) Retention Tank or Contact Tank – This tank is designed to provide sufficient contact time, usually about 20 minutes, for the chlorine to properly serve its intended purpose. If you want to be able to continuously flow 5 gpm, you would need a 120 gallon retention tank. In no case should a system be installed without a retention tank.
(H) Pressure Tank – This tank uses compressed air in a sealed compartment to act as a buffer, storing the pressure created by the well pump. When filled(or at ~50 PSI), this tank should contain about 30% water and 70% compressed air. When nearing empty(or at ~30 PSI), this tank should contain only 2-3% water and 97-98% air. At ~30PSI the well pump should turn on and begin serving the needs of the home and also filling the pressure tank with water. The well pump will continue to run until the pressure reaches ~50 PSI. The experts at GW prefer to install the pressure tank after the retention tank to keep flow going past the injector fitting during normal system operation.
(I) Pressure Switch – Based upon the pressure being sensed, this switch turns on/off the well pump. Most Chlorination water systems also use the pressure switch to turn on/off the chemical feed pump at the same time the well pump turns on/off.
(J) Sample Port – A hose bib or other valve that is installed to test the water quality. It is important to have a sample port prior to the de-chlorination filter. Water at this point should contain the presence of free chlorine, If it does not, adjustments may be required to the chlorination system.
(K) De-chlorination filter – This filter removes the excess chlorine from the water supply, and also a wide variety of organics. The model shown in the image above includes an automatic back-washing controller. If iron or manganese is present in the well water, it is very important to install a back-washing de-chlorination filter.
(L) Water out – Water leaving this point is ready for either further treatment by a softener or other device and/or distribution into the plumbing system.

I got home after a days work at 7 pm on a Saturday only to... realize that I had no water. My initial thought was that I needed a replacement well pump. I called gw immediately and the on call tech (Rick) told me that based on the symptoms I described that he was certain the pump was not the issue. He told me that he would arrive within 45 minutes. He arrived in more like 30 minutes. Rick was prompt, courteous, and highly knowledgeable. He didn’t’t seem to mind me hanging around and learning from him. I feel like in my moment of desperation he could have sold me much more than what was actually needed. I know that I made.the right decision to call gw. I appreciate the honesty and excellent customer service. Thank you - thank you - thank you. All businesses need outstanding techs like Rick!,,,read more

Huge shout out to GW Pumps & Purification for installing... our new hot water heater yesterday. After the old one flooded out last Thursday we set up an appointment with Home Depot to have one installed on Saturday. Well, the tech didn't show up and stopped answering calls so I decided to go local but everywhere was closed Sun/Mon for the holiday weekend. After calling around various places yesterday and being told I would have to wait 1 to 2 weeks GW Pumps & Purification rearranged their schedule and got a guy out yesterday afternoon. The tech, Ray, was nothing but nice and helpful and after being without hot water for 5 days we were back in business!read more

Let me start by saying I have only 4 stars because there is... always room for improvement (I use that in my work also).With that said I had top notch service and have not had one problem since my install about a yr ago. I take care of a building that had a band aid original system, they unstood my needs and concerns to have water on by the end of day when installing an entirely new system.I look forward to working with them again to set my system up to my security system to get system warnings.Thank youNathanOne Harbor Placeread more

I have nothing but great things to say about this... company/team. Polite, punctual, accommodating, and reasonably priced. My shallow well pump went out and I was without water for a little over a day. Everyone I called said they couldn't have a field service rep to my place until 3 days later. Finally, I found GW Pump's info online around 1pm and reached out. After they heard my predicament, they contacted a FSR that was finishing up with another job and got me scheduled for later that afternoon. They assessed/repaired my pump and got everything up and running again for me. I wish there were more stars to give this team. Thank you everyone involved at GW Pumps!read more

I have an under-the-sink reverse osmosis system that... stopped producing water. I called yesterday and could have had someone come out then had I been home, but Gary came out today and was FANTASTIC!!!!! He is very knowledgable and answered all of my questions in layman's terms. He was extremely professional, kind, and caring. I already plan to use this company again in the new year for my routine maintenance for my water softener system. I couldn't be more pleased with this company. Fair pricing, speedy service, kind and professional people, what more can I ask for!read more

In April 2018 GW Pumps and Purification installed a new... pool pump system at my home. Daniel O'Brien was professional, personable, and listened carefully to my wishes, suggesting two options for a new pool pump system to meet my criteria. I selected to install a Pentair/Sta-Rite Brand VS series pump with 1-1/2 maximum horsepower variable speed with motor and electronic control panel for set up of three operational speeds and one "quick clean" speed. My old pool pump motor had burned out, had been extremely noisy, and had been a dangerous eyesore with a mess of tangled wires laying on top of the ground. Gary, the technician installing the new system did an excellent job of working with me to figure out a plan to improve the layout and appearance that has all wires enclosed neatly in conduit on the concrete slab and the remainder of the wires buried underground along with all parts of the system clear of any possible damage from lawn service equipment. I am so pleased with my new pool pump system which is quiet, neat looking, and providing me with great performance. I was very impressed with the high quality of the service and the products of GW Pumps and Purification.read more
