The Well Water Fix Other Companies Cannot Do: Chlorine Injection
in Bradenton.
When a well has heavy iron, sulfur, or bacteria, the box-unit systems hit a wall. Chlorine injection treats the cause — it oxidizes the iron and sulfur and kills the bacteria that make the smell come back — then filters it all out before it reaches your house. It is the system we are known for.

When iron, sulfur, or bacteria overwhelm a basic system
A fine-mesh softener or an air-injection filter is a great fix for a well with light-to-moderate iron and sulfur. But some wells are tougher — heavy iron, strong sulfur, or the real culprit: iron and sulfur bacteria. These are living organisms that build a slimy biofilm in your well, tanks, and lines. Oxidation-only systems do not kill them, so the rotten-egg smell keeps coming back no matter how many times you shock the well. That is exactly where the box-unit companies stop — and where chlorine injection is the answer.
How chlorine injection actually works
It is a controlled, proven process — and one we know cold. A Stenner metering pump, fed from a solution tank and triggered by a flow switch, injects a precise dose of chlorine into your water line only when water is actually moving. The water then flows into a retention tank (or aerator), and this is the part most companies gloss over: it gives the chlorine the contact time it needs to do its job. Disinfection and oxidation are not instant — some things clear in seconds, others need up to 45 minutes of contact time. Size that contact wrong and the system underperforms. From there the water runs through a backwashing carbon filter that removes the oxidized iron and sulfur and takes the chlorine back out, and then into your softener. What reaches your taps is clean, clear, and chlorine-free.
Here is the way to picture it: we are basically building a small, carefully controlled swimming pool for your water — giving the chlorine the time it needs to kill the bacteria and oxidize the iron and sulfur — and then filtering all of it back out so you are not drinking pool water. Our founder spent more than five years running commercial pools right here in Bradenton and Sarasota before water treatment — acids, neutralizers, chlorination, Stenner pumps — so dialing in chlorine dose and contact time is second nature here. (We use Stenner because it is reliable and easy to service — quality, same as everything else we install.) This is the kind of system that rewards someone who actually understands the chemistry, not someone installing a box.
Why it treats the cause, not just the symptom
This is the difference that matters. Air injection oxidizes iron and sulfur, but it does not kill the bacteria that produce them — so the slime rebuilds and the smell returns. Chlorine injection removes the bacteria and the biofilm at the source, which is why, when a test shows bacteria, it is the system we recommend. It is not the “no-chemical” marketing angle, but it is the one that actually solves the problem for good — and the chlorine is filtered out before it ever reaches you.
Custom-built, sized to your water
There is no off-the-shelf box for this. We build each chlorine injection system to your well — matching the pump, contact time, and filter to your actual iron, sulfur, and bacteria levels — on a name-brand Clack valve so it stays serviceable for years. We confirm every number at your free in-home test (or from your lab results) and size it precisely, because an under-built system will not keep up and an over-built one is money wasted.
Technical specifications
Ideal for
- ✓ Wells where the rotten-egg smell keeps coming back after you shock the well (a sign of bacteria)
- ✓ Heavy iron or sulfur that a softener or air-injection filter cannot keep up with
- ✓ Wells that test positive for iron/sulfur bacteria or coliform
- ✓ Reddish or black slime in toilet tanks, filters, or fixtures
- ✓ Anyone who has already tried a “no-chemical” system and still has the smell
Why we build every system on Clack
The control valve is the brain of the filtration side, and it is the part that actually wears out over the years. We build on the name-brand, certified Clack WS1 so you are never trapped: it is easy to service, with no proprietary parts, so a repair down the road is fast and simple — whether our techs handle it or you do it yourself with a video. (See our Fleck vs. Clack breakdown.)
Because a chlorine injection system is custom-built, it carries the manufacturer warranties on the Clack valve and media plus our own labor warranty — a shorter term than a Puronics factory system, but on certified, name-brand parts, and always spelled out in writing at your quote. (Our Puronics systems carry a lifetime manufacturer-defect warranty; we will tell you exactly which applies.)
Maintenance
You top up the chlorine solution periodically — how often depends on your water and usage — and the carbon filter backwashes itself. We keep the whole system on a simple service schedule so it keeps doing its job, and because the filter valve is Clack, service is quick and never locks you into one company.

“I cannot say enough amazing things about this company and system! We had three companies come out and Hydrology stood out on every level.”
“We’ve had our system now a month and absolutely love it. My wife is a hair beautician with over 30 years of experience and definitely can tell the difference with the water.”
“Wow, I can definitely feel a difference in my hair, skin, and when I wash my hands. I knew getting a water softener was a priority and I’m so glad I decided to go with Hydrology.”

What hard water does to a home: the Battelle study →
Will I be drinking or showering in chlorine?
No. The chlorine is metered in only to oxidize the iron and sulfur and disinfect the water, and the backwashing carbon filter removes it before the water reaches your house. The water at your taps is clean, clear, and chlorine-free.
Why not just use air injection (no chemicals)?
Air injection oxidizes iron and sulfur but does not kill the bacteria that cause them. If your well has iron or sulfur bacteria, the biofilm rebuilds and the smell returns. Chlorine injection removes the bacteria at the source, which is why it is the right call when a test shows bacteria.
How do I know if I have bacteria?
The biggest clue is that the rotten-egg smell keeps returning after you shock the well, or you see reddish/black slime in tanks and fixtures. A water test confirms it. If there is no bacteria and your iron/sulfur are moderate, we will recommend the simpler air-injection system instead — we do not oversell.
Does it use electricity?
Only a small metering pump. There is no high energy draw, and there is no salt for the injection side.
How much maintenance is it?
You refill the chlorine solution periodically and we service the system on a schedule. It is very manageable, and we handle the technical part for you.
What is the warranty?
As a custom build it carries the Clack valve and media manufacturer warranties plus our own labor warranty, in writing. Our factory Puronics systems carry a lifetime manufacturer-defect warranty; we will tell you exactly which applies to your system.
