Selectrocide for dairy drinking water
Improve Water. Increase Production. Strengthen the Herd.
Remove slime (biofilm) from waterlines, drinkers and troughs, reduce mastitis and disease pressure, and improve water intake, milk production and milk quality across the milking herd, dry cows, heifers and calves.

The problem
The Cost of Dirty Water on a Dairy
Water is the largest single input a dairy cow takes in every day. The slime you find in a dirty drinking water line is biofilm, and it turns the line, the tank and the trough into a working reservoir that costs you intake, gain and health long before anything looks wrong.
- 01 Slime builds up The slime in the waterline is biofilm, and it keeps reseeding the water passing through to every drinker and trough.
- 02 Cows drink less Off-flavor, odor and visible fouling suppress water intake across the milking herd.
- 03 They eat less Water drives feed intake, so feed conversion slips right along with it.
- 04 Milk production drops Milk production, milk quality, condition and average daily gain all track drinking water.
- 05 More illness and treatment Loose manure, wet bedding, mastitis and hoof pressure, then more labor, more antibiotics, more culls and higher mortality.

Slime Shelters Bacteria
The slime on the inside of a water line is biofilm, a living layer bonded to the pipe. It shelters bacteria from ordinary sanitizers, restricts flow, plugs drinkers and float valves, and keeps reseeding the water passing through. Iron and manganese, mineral and lime scale buildup, organic matter and the algae behind green water in an open tank all build up alongside it and make the problem worse.
Why Bleach Falls Short
Chlorine loses strength as pH climbs. Above about 7.5 it converts to hypochlorite ion and gives up most of its killing power, and most farm water sits right in that range. Bleach, acids and peroxides are also consumed by organic load before they reach the biofilm, so repeated shock chlorination costs more every time and is hard on drinkers, tanks, fittings and lines. The result is poor water quality holding back intake and performance, plus labor inefficiency and overcomplicated chemical programs.
Cows Drink Less
Off-flavors, odor and visible fouling suppress water intake. Cows and calves that drink less eat less, and feed conversion, milk production and milk quality follow the water.
A Route for Reinfection
You can clean the parlor, the alleys and the footbaths and still put pathogens like Salmonella, E. coli and Prototheca back through the water line. Until the line itself is clean, the drinking water keeps handing the problem back to the herd.
How it works
From the tote to the trough.
See how the system works from start to finish: make chlorine dioxide in the tote, pull it into the water line with a proportional injector, and send treated water through the lines to every drinker.
Livestock water treatment system showing chlorine dioxide generated in a tote, drawn into the incoming water line by a proportional injector, and carried through the water lines to the drinkers.
Make it on site
Drop the pouch into a tote of water. It generates Ultra-Pure chlorine dioxide right there on the farm.
Connect the injector
Run the tote into a proportional injector on your water line, including Dosatron style units.
Set your treatment rate
Set the injector for the concentration you need.
Treat every drinker
Treated water moves through your existing lines all the way to the last drinker in the barn.
No generators, no bulk chemical mixing, no complicated equipment.
The solution
Where Selectrocide® Works on a Dairy
Drinking Water Systems
Ultra-Pure chlorine dioxide generated on site in a sealed micro-reactor. Continuous low ppm dosing and shock treatment for waterlines, drinkers, troughs, tanks and wells.
- Destroys bacteria and pathogens in the water system
- Removes and prevents biofilm and slime
- Oxidizes iron and manganese buildup
- Improved water intake, feed conversion and milk production
- Cleaner water, drinkers and troughs, and lower mortality
- One program replaces or reduces several chemicals

Water Treatment for Dairy Farms
Selectrocide cleans the water, strips biofilm already built up in the lines, and keeps new build-up from taking hold.
< 1 ppm
Municipal water
Continuous dosing rate for municipal water sources.
1–2 ppm
Well water systems
Higher organic load in well water may require up to 2 ppm.
< 0.8 ppm
Residual before consumption
Residual chlorine dioxide should remain below 0.8 ppm before cows drink.
20–50 ppm
Initial shock treatment
Used to flush and clean the system before transitioning to maintenance.
Waterline Dosing and Treatment Guide
- Test at the drinker, not only at the dosing point.
- Adjust the program to the actual water source and system.
- Always confirm the rate for your application on the product label.
Exact dosing varies by water source, organic load, and system type. Water testing is recommended before establishing a final protocol.
