Whole house filtration system Cognitive-behavioral therapy for depression from bacteria, viruses, Non-chemical water purification systems and other contaminants commonly found in well water. Policy Collaboratory through the N. Traditional distillation and reverse osmosis systems do excellent jobs purifying the water, but filter out all the trace minerals that are naturally found in good quality drinking water. Looking for these certifications is a good place to start.

Non-chemical water purification systems -

The American Academy of Pediatrics links neurotoxins to:. The EWG found aluminum in the tap water of 30 states and fluoride in all of them. There are dozens of toxins in tap water.

The ones below are just some of the most dangerous. Fluoride is a controversial naturally occurring mineral found in groundwater.

Municipal water supplies in all fifty states add fluoride to drinking water, but research shows it acts as a neurotoxin to children in utero. In a study of Mexican mothers exposed to fluoride while pregnant, researchers found cognitive delays and low test scores in their children. Globally recognized as one of the worst neurotoxins for both children and adults, lead is a heavy metal commonly found in old homes.

Over the last four years, my lead investigations revealed:. Lead in household items like plates, chords, shoes, and toys. Lead paint on the Green Sprouts Sippy Cup.

Lead solder on the Planet Box insulated water bottle. Lead also leaches from older pipes into the tap water in communities all over the United States and the world. Most recently we have seen this in Flint, Michigan.

Did you know cancer-causing pesticides and herbicides end up in your water supply? The clothing industry and conventional farming are two contributors. Cotton fields used for traditional clothing production contaminate bodies of water and your family with toxic fertilizers. A carbon cartridge like the Pure Effect Superblock uses activated carbon particles to trap cancer-causing compounds.

Here are some of the most common cancer-causing toxins that Pure Effects removes:. Manufactures use PFAS or toxic fluorinated chemicals to produce firefighting foam and water repellent fabrics that contaminate the water supply.

A two-year laboratory study of rats and mice proves chromium-6 causes cancer in animals. Previous studies also show links to lung and stomach cancer from worker exposure in industrial environments. The EPA continues to stall chromium-6 regulations while two-thirds of Americans are exposed to this cancer-causing compound from their water supply.

In addition to pharmaceuticals, creams, lotions, perfumes, and over the counter drugs contaminate the water supply. A Associated Press report found everything from antidepressants and anti-anxiety medication to painkillers like Valium and synthetic estrogen found in oral contraceptives in the water supply—after water treatment.

Synthetic estrogen in the water supply hurt the fish population, too. A series of studies found male fish causes males to develop eggs in the testes, so what is it doing to developing children?

Sewage treatment plants are not currently designed to remove pharmaceuticals from water. Nor are the facilities that treat water to make it drinkable. There are hundreds of different types of water filters on the market.

I own both a whole house Friend of Water and a Pure Effect under-counter sink system. I love both for different reasons. Most water pitchers are inexpensive, made of plastic, and do a poor job of filtering a large amount of toxins.

Only a few pitchers remove lead or chromium. Some NBM readers report having to change the filters frequently. We use this when we travel. Gravity-fed water filters are a popular and affordable countertop option. One popular filter is the Berkey water filter.

The company claims to remove all kinds of contaminants, including fluoride. There are better whole house and countertop options available at a similar price point. The membrane separates any contaminants besides water molecules from passing through, stripping the water of natural minerals and electrolytes in the process.

Another downside is water waste. An RO system uses between four and five gallons of water to filter one. After looking at the above options, I decided to test two made-in-the USA whole house and countertop filters. I recommend either Friends of Water or Pure Effect for the best whole house water filter.

I recommend Pure Effect for the kitchen countertop models. Both companies target the toxins in water without removing necessary minerals.

Take a look at my guide on testing water filters and the pros and cons of each below before deciding what system is best for your home. Note: The ZeroWater pitcher and Mountain Valley Spring Water bottles are great options to use while waiting for your filter to restock.

Pure Effect is a boutique New York company that specializes in top of the line water filters. I recommend either the Pure Effect countertop or whole house filters for removal of all toxins currently Pure Effect is back-ordered on their whole house system until late Pure Effect water filters:.

The UV system is best in case of resistant microorganisms or water treatment plant failure, according to Igor, the CEO of Pure Effects. Timothy from Friends of Water can work with you to choose the best whole house water filter for your needs.

I found through testing that Pure Effect has better contaminate removal from their kitchen countertop models.

Instead of inexpensive materials or removing minerals, Pure Effect and Friends of Water use parts made out of natural materials like zeolite to leave minerals in and filter toxins out.

Then, contact both companies to see which filter is right for you. Did you find the best water filter for your family? Comment with your experiences and thoughts below, and subscribe to my newsletter for non-toxic living tips and guides for your entire family.

I mention in my longer post about water filters that I used two labs. National Testing Labs or Kar Labs. I have also tested at a local water testing facility. You can google water testing and your city and see if anything comes up.

Do you have a recommendation for a bath tub filter? Wanting to filter the water in birth tub at a birth center. At this point I feel like testing is the only way to know for sure how different filters work.

How is the water flow rate with the PE filter? I have low water pressure in my house so concerned it will run very slowly.

Have you looked into insinkerator filter? I have it for countertop filter with instant hot water dispenser. Does it have a filter in it? I have instant hot water as well. I wonder if there is a comparative chart showing the results from Berkey, Friends of Water, and Pure Effects..

Chemical scale inhibitors are also routinely used to enhance the solubility of these scale-forming salts. More recently, a new method of scale control has been introduced that removes these scale forming impurities by the electrochemical deposition of calcium and magnesium and other salts at the cathode of an electrochemical cell.

Direct current is applied to the cell at a rate sufficient to drive the precipitation reactions at the cathode. These devices are electro-synthesis cells that produce a buildup of calcium hydroxide, magnesium hydroxide and other salts at the cathode.

These insoluble salts are then removed to allow the continued flow of current from anode to cathode. The driving force for the electrochemical cell reaction is determined by the voltage applied between the electrodes. The total voltage is determined by the theoretical voltage, which is the sum of the anode and cathode half-cell voltages; the overvoltage required to achieve the desired production level; and the electrolyte resistivity water resistivity.

This determines the total cell voltage required to drive the reaction. The current requirement can be estimated from a formula worked out by Faraday that expresses the quantity of electric charge required to produce the desired yield of precipitated salt. This is the product of the electric current and the length of time it flows through the cell.

The estimated power requirement is determined by multiplying the voltage times the current flow to yield the kilowatt-hour per kilogram of salt produced. Because of the high electrical resistance of water, the power cost for this process can be significant over traditional chemical treatment methods.

Other factors that should be reviewed with this process include the cost for equipment maintenance, solids disposal and electrode replacement. As with all electrochemical processes, the selection and durability of the anode is important. Ozone: Ozone is second only to fluorine as an oxidizing agent.

As such, ozone functions as a very strong oxidizing biocide in cooling towers and drinking water systems. It has been marketed as an alternative to other oxidizing biocides, such as chlorine and bromine, for bacteria and algae control in cooling towers since Ozone is produced in a corona discharge generator by passing a stream of dry air through an electric arc to yield O 3.

The generators come in various output capacities depending on the rated capacity of the cooling tower and microbiological demand. Typically, 0.

The power consumption is about 15 kWh per pound of ozone produced. Most experts agree that ozone is very effective in controlling microbiological growths in cooling towers. However, additional claims by ozone proponents that it conserves water, prevents scale deposition and mitigates corrosion are in dispute.

Some ozone programs have been applied with no tower bleed resulting in the deposition of a white sludge in the tower basin and low flow areas of the system. Because it is such a strong oxidizing agent, ozone tends to attack materials of construction if overly applied or poorly controlled.

Ultraviolet light: Ultraviolet UV lamps produce light with a wavelength of nm. When bacteria are exposed to UV radiation, the organisms are rendered unable to reproduce and thus considered dead.

This process is most effective in water that is relatively clean and pure to minimize the absorption of light by suspended solids and other debris. Ultraviolet light is only lethal during the time that the organism is exposed directly to the light.

It produces no residual effect in the water and therefore, does not kill biofilms that form on surfaces not exposed to the UV radiation.

Another class of non-chemical water treatment methods that have come into their own in the last 30 years is reverse osmosis RO and electro-deionization EDI. Reverse osmosis RO : RO utilizes a pressure differential across a semipermeable membrane to reject dissolved salts at the membrane surface while allowing the purified water to permeate through the pores of the membrane.

These membrane separators have been fabricated in a variety of configurations including spiral wound and hollow fiber modules.

For more information, see: Strategies for Water Reuse, CE, September , pp. Unless a use for the RO reject is found, reverse osmosis will consume more fresh water than ion exchange. Electro-deionization EDI : This process is similar to RO in that it utilizes ion exchange membranes and resins to separate the feedwater into a purified water stream and a concentrated brine stream.

The potential difference between the electrodes creates the driving force across the membrane. Positively charged ions selectively pass through the membrane and are attracted to the cathode.

Negatively charged ions are separated by the membrane and move toward the anode. The result is a final product stream of de-ionized water as illustrated in Figure 3. Reverse osmosis and electro-deionization are used in many applications to replace more traditional ion-exchange processes.

When used in place of ion exchange demineralizers, for example, the acid and caustic regeneration chemicals can be eliminated. This limits worker exposure to these chemicals, reduces the amount of acid and caustic discharged to waste, and eliminates the need to purchase, ship, store and handle corrosive chemicals.

The non-chemical water treatment methods discussed in this article share one thing in common. They utilize electric current in one fashion or another to condition water.

Instead of buying, shipping, storing and feeding chemicals to prevent scale, mitigate corrosion, and control microbiological growths, these devices simply plug into the wall. This feature offers many benefits at a time when plants are seeking ways to decrease worker exposure to hazardous chemicals and reduce waste disposal costs.

However, as indicated, some of these devices make claims that are difficult to substantiate based on independent, unbiased, scientific evaluation. As expected, the manufacturers of this equipment offer testimonials and case studies to support their claims.

Notwithstanding claims to the contrary, many cases have been reported where the equipment failed to perform as advertised, resulting in equipment damage and unscheduled downtime.

For this reason, it is best to seek the advice of an unbiased, knowledgeable expert when considering the application of non-chemical water treatment methods. The good news is that when properly applied, many of the non-chemical technologies discussed in this article help plants conserve water, reduce chemical consumption, minimize waste, and save energy.

This is not only good for the environment, but good for business, too. Eliassen, R. Water Works Assoc. William Harfst is president of Harfst and Associates, Inc.
