The Best Method to Treat Surface Water – Lakes and Ponds

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 bacteria.

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 like this:

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!
