Let us cut right to the chase. If you have read any of very own past articles
during the nearly 20 years I have written this blog, you might know one thing: I
am not a big fan regarding chlorine. There are a few reasons:
It is hard to keep the correct concentration involving chlorine as it degrades rapidly; The “point-of-injection” can crystallize and necessitate cleaning the injection fitting (not really hard, but it takes time); and
Chlorine combines with organics in the water and forms carcinogenic disinfection by-products (DBP’s) like trihalomethane (THM) – and that is the prime reason When i dislike chlorine.
That said, I would not even think about using anything but chlorine to treat and lake, pond or surface water supply. Why? Because there is not another process that works as properly and economically as chlorination! Chlorine is a good disinfectant in addition to disinfection is certainly needed with any surface water supply, as it might contain harmful bacteria, such as e-coli, giardia, and cryptosporidium. Pairing chlorination and other sub-micron filtration rids the water of these products.
Additionally , most surface water contains algae (at smallest
seasonally) and chlorine is one tried and proven technique for killing it.
Prolonged contact and continuous feeding connected with chlorine is the ONLY
tried and true method of treating surface standard water. Just because you are
using chlorine, does not mean there are disinfection by-products in your water
supply. You see, we take out the excess chlorine plus DBPs with prolonged
contact with Coconut Shell Granular Set off Carbon GAC) so that after treatment,
the water is together bacterially and chemically pure. The chlorine and many
other harsh chemicals that are potentially present are gone, as well as the
I had a good gentleman last week tell me that he was
disappointed I recommend chlorine for the “makeup water ” for his coy
water-feature, as well as his homes water supply. He was upset because the guy
didn’t want to use chlorine. He would have been more upset should i hadn’t
recommended it. Some people have tried hydrogen peroxide H2O2) and I admit that
I too have tried the fact that, I am a big fan of H2O2 Technology… except on
pond or surface water treatment.
You see, H2O2 is a popular oxidizer, but
not a good disinfectant. Chlorine is a great disinfectant, yet not a good
oxidizer. Hydrogen peroxide works well when you use it as the oxidizer, like
iron and sulfur removal. You have to usage chlorine on surface water, no ifs,
ands as well as buts! Technically, you could also use ozone, but at an
astronomical cost: 3 or 4 times more than chlorine for a properly-sized product
and even that is problematic.
The gentleman I mentioned above was
initially concerned that chlorine would be able to get into his coy pool. NOT
TRUE! The chlorine is consumed in the process and the extra is removed with
prolonged contact carbon filtration. Certainly no chlorine will be present in
the water supply. A typical Chlorination Product for surface water might look
From left side to right, you have the Proportional
Injection System above the White Chlorine Storage Tank that is where you mix the
very chlorine with water). Next, you have the Retention/Contact Water tank or
Tanks, followed by one or two depending upon the system) Backwashing Carbon
Filters. Finally, there are Two Post-Filters and in many cases, a strong
Ultraviolet Light just for bacterial redundancy.
Surface water will be site-specific, so if your lake or pond is provided with by a spring or well, you may need a water softeners or simply Iron Filter. In some cases, excessive sand, sit or muck necessitates the use of a Backwashing Sediment Filter and if you possess tannin, you may want to consider utilizing a Pulsr Disrupter Cartridge.
An individual final word of advice: Since “prolonged contact”
is so vital in killing bacteria as well as removing the chlorine, it’s better to
go a little too big, than too small. Prepare that one down. Remember, after 45+
years of doing this (and making a lot of mistakes along the way), The (Water)
Medical professionsal knows best!
