ESIL RESEARCH

advanced pharmaceutical removal

TESTING:
​On July 27, 2015, ESIL researchers conducted a lab test on the effectiveness of ESIL treatment in removing pharmaceuticals from water.  A spiked sample of pharmaceuticals was purchased from ALS Environmental Laboratory in Waterloo, ON.  5ml of the spiked sample was added to 20 gallons of water in a mixing tank.  A sample bottle was filled from this tank which constituted the "Pharma-Raw" sample.

An ESIL Home Unit was set up to draw water directly from the mixing tank containing the pharmaceuticals.  The ESIL unit was powered on and treated several gallons of water directly from the tank before a sample of the treated water was taken.  The treated water was passed through the ESIL system only once.  The sample taken constituted the "Pharma-Treated" sample.

Samples were taken to ALS Laboratory where the results were processed.

The Results were exceptional.
ESIL technology removed pharmaceutical contaminants to levels below detection.  The only remaining contaminant detectable had been reduced by more than 99%.
​We are proud of our test results.  Feel free to view the original documentation below.

nIAGARA BREW CLUB CASE STUDY

Owner of Niagara Brew Club Tests Quality of ESIL Water for Brewing

Jeff Chcoski - Owner of Niagara Brew club prepared six separate batches of beer using three types of beer.  For each type of beer, one was prepared with ESIL treated water and one was prepared with his current water filtration system.

Results:
1. Fermentation occurred more rapidly and yeast was much more active in the ESIL treated water batch.  In the image to the right, the ESIL treated water is shown on the left with yeast overflowing.  Their regular treated water shown on the right to be much less active.
2. Boiling occurred faster for the ESIL treated brew than the comparison on all three occasions.
3. 0.5% higher alcohol content was present in 2 of the 3 ESIL treated beers when specific gravity was tested for all batches.

Discussion:

1. Fermentation may have occurred more rapidly and to a greater extent in the ESIL water because the yeast had a non-competitive environment within which to propagate.  When heavy metals and bacteria are present, they draw oxygen as they oxidize and metabolize.  Their presence causes competition for the available oxygen and therefore limits the amount available to the yeast.  By removing these contaminants, the yeast has access to all of the available oxygen and therefore, thrives.
2. Boiling may have occurred more rapidly due to the removal of contaminants.
3. Higher alcohol content may have occurred due to the more active yeast.

esil PROCESS WITH eFFLUENT WASTEWATER

ESIL Trial: Hamilton Wentworth Wastewater 1992

Purpose: 
Test the capability of the ESIL system to treat organics (bacteria, viruses) in wastewater (primary effluent).  Current treatment for wastewater at this location involves heavy use of chemicals and time for particles to settle before being treated and discharged into Hamilton Harbour via Windemere Basin.

Testing:
A sample was taken from Woodward Ave. wastewater treatment plant.  The sample was taken after primary clarifiers had been added (settleable solids were removed).  The sample was sent to Acres Analytical Ltd. in Niagara Falls for testing.

COD (chemical oxygen demand) was tested as the indicator of effectiveness.  
This represents the level of bacteria present in the sample.

Conclusions:
COD was reduced from 484 ppm to undetectable levels.  
In one pass through the ESIL system, the water met the Ontario Drinking Water Objectives (ODWO) standards for potable water.
Settling rate of sediment was 10 times faster with the ESIL system than that achieved with chemicals.

Environmental Implications:  
The inorganic solids produced through this treatment were found to be readily settleable and easily removed.  These solids not only have a recyclable value, they also no longer require aerobic digestion, incineration or disposal in a landfill.  These once-hazardous solids are now inert.

What is COD?

What is Potable Water?

What is effluent water?

In environmental chemistry, the chemical oxygen demand (COD) test is commonly used to indirectly measure the amount of organic compounds in water. Most applications of COD determine the amount of organic pollutants found in surface water (e.g. lakes and rivers) or wastewater, making COD a useful measure of water quality.

Potable water is water which has been classified as safe to drink.

Primary effluent includes water flowing through the sewers and storm drains or the waste water discharge from industrial facilities.

In the context of wastewater treatment plants, effluent that has been treated is referred to as secondary effluent.

e.coli test

In December 1995, ESIL commissioned Walker Laboratories of Niagara Falls, Ontario to conduct a test on the effectiveness of the ESIL water treatment system at eliminating E.coli. Results are shown below.


RESULTS:
As seen below, the E. coli level in raw effluent was reduced from 3,200,000 counts/100ml to less than 2 counts.
This is a reduction of more than 99.99% after a single pass through the ESIL treatment process. 

The electricity in the ESIL treatment process kills bacterial and viral organisms such as E. coli, Giardia, and Cryptosporidium.

esil vs other treatment methods

Our Quality is What Sets us Apart

The ESIL Treatment process consistently provides water free from contaminants while delivering all the naturally occurring beneficial minerals.

Undesirables such as arsenic, lead, cyanide, mercury, pharmaceuticals and bacteria are removed.
Beneficial Minerals such as Calcium, Magnesium, and Potassium remain at their naturally occurring levels.

See the chart below for a discussion on how ESIL water compares to other treatment methods.

Compared to Reverse Osmosis

Reverse Osmosis cannot deliver the same continuity in results as ESIL. RO forces water through a fragile semi-permeable membrane. The membrane stretches over time, gradually allowing larger particles through. RO systems cannot deliver a continuously consistent level of bacteria removal. The sensitive membrane is also compromised by even trace amounts of oil or chlorine which commonly occur in tap and well water.

RO removes beneficial minerals along with contaminants. The water that is produced with RO filtration is void of minerals.  Refer to the World Health Organization's article on demineralised water for a more in depth look at the health risks associated with it.

Compared to Tap Water

Tap Water is treated with chlorine. Chlorine will kill any bacteria in the water. It will not, however, eliminate heavy metals, pharmaceuticals or any other undesirables in your water. Using chlorine produces THMs (trihalomethanes) as a reaction occurs between chlorine and bacteria. The THMs will remain in the water after the chlorine has dissipated, leaving a carcinogenic substance behind that can be absorbed internally through drinking or externally while bathing.

Chlorine will not reduce the harmful levels of pollutants in the water from ground contaminants such as fertilizers or nitrates. Nor will it remove pharmaceuticals that are becoming an increasing concern in our tap water sources.

Compared to spring Water

On a given day, spring water may be acceptable to consume while the next day, it may be unfit to drink.  For example, After a rainstorm, ground contaminants such as pesticides and fertilizers get flushed into spring water sources.  Spring water does maintain the natural minerals after being treated with UV lamps.  Inorganics such as arsenic, lead, cyanide and mercury, however, also remain.  UV lamps are rarely 100% effective. The effectiveness of treatment is variable depending on flow of water and scale build up on the lamp.

World Health Organisation advises against drinking R.O, Distilled and other demineralised waters 

According to a research report by the World Health Organization (WHO), there are significant health risks to drinking demineralised water and the ideal range for drinking water is between 100-500 mg/L TDS (total dissolved solids).  
ESIL water is NOT demineralised.
​
We drink water because our bodies need it. More so now than ever before, we are concerned about contaminants in our water that may be hazardous to our health. We should also be concerned that the water we are drinking still contains healthful minerals.

ESIL Technology is good for the Earth.

The ESIL process does not waste ANY water  

Traditional filtration  re-locates contaminants to a landfill where they seep back into the water supply.  After the ESIL process, contaminants are ion-bonded and inert .  They   will never again enter and influence   the water supply.

Minimal power requirements allow units to run off-grid.
