WATER PURIFICATION SYSTEMS

Water purifi­ca­tion is the process of remov­ing unde­sir­able chem­i­cals, bio­log­i­cal con­t­a­m­i­nants, sus­pend­ed solids and gas­es from water with the goal of pro­duc­ing water fit for a spe­cif­ic pur­pose. Most drink­ing water goes through a dis­in­fec­tion process, but water purifi­ca­tion may also be designed for oth­er pur­pos­es, includ­ing ful­fill­ing the require­ments of phar­ma­co­log­i­cal, med­ical, chem­i­cal and indus­tri­al appli­ca­tions, or just to upgrade the drink­ing water sup­ply. The meth­ods used include phys­i­cal process­es such as sed­i­ment fil­tra­tion, car­bon based fil­tra­tion, sed­i­men­ta­tion with sand fil­ters; chem­i­cal process­es such as floc­cu­la­tion and chlo­ri­na­tion and the use of ultra­vi­o­let light or ozone.

FOR YOUR HOME OR BUSINESS

On an indi­vid­u­al­ized basis, water purifi­ca­tion sys­tems can be installed for the removal of almost any of the poten­tial water qual­i­ty con­cerns you may have.  For exam­ple, lead is typ­i­cal­ly removed from drink­ing water with either a reverse osmo­sis water purifi­ca­tion sys­tem or a car­bon fil­ter designed specif­i­cal­ly for the removal of lead from water. Water soft­en­ers are typ­i­cal­ly installed to remove dis­solved iron or man­ganese and hard­ness min­er­als in the water through a tech­nol­o­gy called Ion Exchange (see below for more detailed infor­ma­tion on this).  A water soft­en­er will also remove dis­solved lead from the water as well, how­ev­er they are usu­al­ly installed ahead of the pip­ing where the poten­tial for lead leach­ing is most like­ly to occur and is not rec­om­mend­ed for this pur­pose.  To remove par­tic­u­late iron or man­ganese, a prop­er­ly sized sed­i­ment fil­ter is required.  Radon or arsenic in the water requires oth­er tech­nolo­gies and sys­tems.  Start­ing with a water test is the best way to deter­mine what type of water purifi­ca­tion sys­tem makes the most sense.

In addi­tion to the above sys­tems described, there are many oth­er types of sys­tems to remove bad tastes & odors, sed­i­ment and many oth­er objec­tion­able min­er­als and con­t­a­m­i­nants in the water.  For more detailed infor­ma­tion on bad odors and tastes that may be present in your water, see the link at: http://h2ocare.com/bad-odor-taste-water/.

HOW HARD IS THE CAMBRIDGE WATER SUPPLIED BY CAMBRIDGE WATER DEPARTMENT (CWD)

Water purification for Cambridge, MA

Accord­ing to CWD, the hard­ness of the city’s tap water is typ­i­cal­ly around 40 to 60 parts per mil­lion or 3 to 4 grains per gal­lon.  See the chart at left for com­par­i­son.  CWD’s water is “slight­ly to mod­er­ate­ly hard” and varies only slight­ly through­out the city. Hard­ness also varies slight­ly by sea­sons of the year.  A water soft­en­er can imme­di­ate­ly solve the issue of hard water in your Cam­bridge home. Water hard­ness refers to the con­tent of the min­er­als cal­ci­um and mag­ne­sium in your water.  When using dish­wash­ers, you may notice a slight increase in “spot­ting” or streak­ing on glass­ware, flat­ware or white residue in kitchen­ware and show­ers.  This residue con­sists main­ly of cal­ci­um car­bon­ate, the same ingre­di­ent found in anti-acid prod­ucts and not a known health risk, how­ev­er the aes­thet­ic affects in your home can be dam­ag­ing and annoy­ing.   Also, over the course of time, it is pos­si­ble to accu­mu­late dam­ag­ing scale build-up inside your home’s pip­ing dis­tri­b­u­tion sys­tem which can be expen­sive to fix or replace.

 

THE AFFECTS OF HARD WATER

Hard water inter­feres with many clean­ing tasks, from doing the laun­dry to wash­ing dish­es to tak­ing a show­er. Wash­ing your hair in hard water may leave it feel­ing sticky and dull.  Dish­es and glass­es get spot­ted and a film may build up on show­er doors, bath­tubs, sinks and faucets.  Clothes can look dingy and feel rough and scratchy.   Mag­ne­sium and Cal­ci­um may have major affects on your home’s plumb­ing and your abil­i­ty to clean, even though the EPA has no pub­lished lim­its on these.  Scale from hard water can build-up inside water heaters insu­lat­ing the tem­per­a­ture sen­sor inside the tank cre­at­ing extra work to bring the tem­per­a­ture up to the set lev­el.  This reduces the life of your hot water heater and will like­ly require ear­ly replace­ment.   Hard water can also cause scale build-up in pipes that can low­er water pres­sure through­out the home.

DAMAGING HARD WATER SCALE UN-CHECKED

The pri­ma­ry hard water min­er­als are cal­ci­um and mag­ne­sium (the hard­ness min­er­als), while iron and man­ganese (“The Stain­ers”) can also be found in water, most­ly in pri­vate wells.  Depend­ing on whether the contaminant’s form is in solu­tion or par­tic­u­late, these con­t­a­m­i­nants can be removed with a water soft­en­er and/or a prop­er­ly spec­i­fied sed­i­ment water fil­tra­tion instal­la­tion.

A water soft­en­er will improve your water great­ly if you have hard water min­er­als, iron, or man­ganese in your water.   If oth­er impu­ri­ties are con­firmed in the water test, they can be removed with oth­er types of water fil­tra­tion sys­tems.  The max­i­mum allow­able lev­el (per the Envi­ron­men­tal Pro­tec­tion Agency) for iron as a sec­ondary con­t­a­m­i­nant is .3 parts per mil­lion and for man­ganese is .05 parts per mil­lion. Small amounts of these min­er­als can have very notice­able, even dam­ag­ing affects on your home’s water qual­i­ty.

Water soft­en­ers vary, includ­ing up-flow ver­sus down-flow which can make a big dif­fer­ence, par­tic­u­lar­ly if there are ele­vat­ed lev­els of iron or man­ganese in the water.  In some cas­es where the water chem­istry is more com­pli­cat­ed, a dif­fer­ent type of water fil­tra­tion sys­tem may make more sense to remove iron or man­ganese.
