Catalynt’s liquid copper sulfate disperses on contact — no crystals to break down, no product settling to the bottom, and no guesswork on dosing. It’s manufactured domestically and backed by a supplier that already serves the water treatment industry at scale.

Why Utilities and Contractors Choose Liquid Copper Sulfate

Crystal copper sulfate has a well-known problem: it sinks. Once it hits the bottom of a reservoir or pond, a share of that copper never reaches the algae it’s meant to control, and someone has to go back and apply more. A liquid formulation solves that at the source.

• Disperses immediately through the water column — no manual broadcasting or dragging
• Meters precisely through standard chemical feed pumps for repeatable, auditable dosing
• No dust exposure during mixing or loading, unlike bagged crystal
• One consistent product across your whole treatment season — no lot-to-lot variability from dissolving crystal on site

Where It’s Used

• Municipal Water Treatment Applied at raw water intakes, reservoirs, and basins to control algae before it becomes a taste, odor, or filtration problem. Dosing follows EPA label limits, including Lead and Copper Rule considerations for finished drinking water.
• Lakes, Ponds & Reservoirs Used by lake management contractors, HOAs, and golf courses to control algae and cyanobacteria blooms in impounded water without the labor of spreading crystal by hand.
• Irrigation Canals & Districts Keeps conveyance systems and canals clear of algae growth that restricts flow and clogs filtration and drip equipment.
• Wastewater Lagoons Controls odor-causing bacteria in lagoons and wastewater basins alongside standard neutralization chemistry.

FAQ

1. Is liquid copper sulfate safe for drinking water treatment? Yes, when applied according to EPA label directions and dosed within Lead and Copper Rule limits for finished drinking water. Always follow the label and consult your state drinking water program for permit requirements.
2. How is liquid copper sulfate different from crystal copper sulfate? Liquid copper sulfate dissolves and disperses instantly, so it doesn’t sink or settle like crystal. That means more even coverage, less wasted product, and no dust exposure during handling.
3. What size containers does Catalynt offer? Liquid copper sulfate is available in 1-gallon, 2.5-gallon, 30-gallon, 55-gallon, and 275-gallon tote sizes, plus bulk tanker delivery for large-volume municipal and industrial accounts.
4. Is Catalynt’s copper sulfate NSF/ANSI Standard 60 certified? NSF/ANSI Standard 60 certification is in progress. Contact Catalynt for the current certification timeline and to be notified when it’s finalized.
