Water Treatment Chemicals

Chemistry for the People Who Treat Water

Hepure has supplied remediation chemistry since 1994, and much of what we ship into contaminated groundwater does the same work in a treatment plant. Permanganate oxidizes iron and manganese. Ferrous iron reduces hexavalent chromium. Calcium polysulfide precipitates metals as sulfides. Activated carbon adsorbs organics, and zero valent iron reduces selenium. The difference is the reactor: a tank, a filter, or a pond instead of an aquifer.

We don’t design or operate treatment systems. Your engineer, operator, or treatment provider sets the process. Our job is getting them the right chemical in the right form, the data behind it, and a supply they can count on, along with straight answers about how each product behaves in water. This page lists what we supply for each kind of water and links to the water treatment details on every product page.

Oxidants

Oxidants turn dissolved iron, manganese, and sulfide into solids that settle or filter out, and they break down organics that cause odor or resist biological treatment.

Potassium Permanganate

The long-standing oxidant for iron and manganese removal, hydrogen sulfide, phenols, and manganese at mine sites. It stays active long enough to finish in a contact basin, and the water stays pink until the demand is met, which makes it easy to control. Dry crystals in 55-lb pails and 330-lb drums, or pre-mixed solution up to 5%. Water treatment uses

Sodium Permanganate

The same permanganate chemistry as a 40% liquid that feeds straight from a metering pump: no dissolving tank, easy dose changes, and simpler logistics at remote sites. Drums, totes, or tankers, at full strength or pre-diluted. Water treatment uses

Hydrogen Peroxide

Oxidizes sulfide for odor and corrosion control, drives Fenton’s chemistry with ferrous iron for phenols and other hard-to-treat organics, destroys free and weakly complexed cyanide, and serves as the oxidant in UV advanced oxidation. It breaks down to water and oxygen, so it adds no salt. Quoted from 3% to 35% by weight. Water treatment uses

Powdered Activated Carbon

Carbon adsorbs what oxidants can’t touch or shouldn’t: taste and odor compounds, trace organics, and PFAS. Both of our carbons are powdered. You dose them into water and remove them with the solids; they aren’t made for packed filter vessels.

CarbPure TRA

Our potable-water carbon: certified to NSF/ANSI 61, meets ANSI/AWWA B600-16, iodine number of at least 800 mg/g, and formulated for fast adsorption when contact time is short. It targets geosmin and MIB, algal toxins, DBP precursors, atrazine, and PFAS. Supersacks or pneumatic bulk trailers, for wet or dry feed. Water treatment uses

Fluxsorb RP

Domestically manufactured powdered carbon for contaminated waters and sediments where potable certification isn’t required: batch treatment of process water and collected stormwater, and amending contaminated pond and basin sediments. Bulk bags or bulk trailers. Water treatment uses

Reducing and Precipitating Agents

Some contaminants won’t leave the water until they’re chemically reduced, hexavalent chromium and selenium among them, and dissolved metals often need sulfide or iron to get below discharge limits.

Ferrous Sulfate

Reduces hexavalent chromium to Cr(III) across a wide pH range, catalyzes hydrogen peroxide in Fenton’s treatment, and forms iron floc that co-precipitates arsenic and chromium. 50-lb bags, with the hydrate form and assay stated on the certificate of analysis. Water treatment uses

Remotox Calcium Polysulfide

Reduces Cr(VI) and precipitates lead, zinc, cadmium, and copper as sulfides, which are far less soluble than hydroxides. It fits industrial wastewater, mine water polishing, and batch treatment of metals in collected stormwater. 29% solution in pails, drums, totes, or tankers. Water treatment uses

Ferox PRB Zero Valent Iron

High-purity granular iron, more than 95% Fe with 96% in the 20/60 mesh range. It reduces selenium in mine water, captures dissolved phosphorus when mixed into stormwater sand filters, and serves as the reactive media in barriers that treat seepage. Water treatment uses

pH Control

Sodium Hydroxide

Neutralizes acidic water and raises pH for hydroxide precipitation of metals: in industrial wastewater, at small and remote mine sites where a lime plant doesn’t make sense, and in batch treatment of collected runoff. 25% solution in 560-lb drums and 2,400-lb totes, or blended to the strength your feed system wants. Water treatment uses

Electron Donors for Biological Treatment

Emulsified Vegetable Oil and Sodium Lactate

Bacteria that reduce nitrate, selenate, and sulfate need an electron donor, and the sulfide they make from sulfate precipitates dissolved metals. Emulsified vegetable oil releases slowly, over months to years, for in situ and passive treatment of mine water and seepage. Sodium lactate ferments within days for a fast start. Water treatment uses: emulsified vegetable oil, sodium lactate.

What We Supply Beyond the Drum

• The right form for your feed system. Dry or pre-mixed potassium permanganate, 40% or pre-diluted sodium permanganate, peroxide from 3% to 35%, and sodium hydroxide at 25% or a custom strength.
• The paperwork your files need. Safety data sheets, specification sheets, and certificates of analysis. If you need a document we haven’t posted, we’ll send it.
• Quantity math. Give us your design dose and flow, and we’ll turn them into order quantities, packaging, and a delivery schedule.
• Delivery that fits the schedule. Distributor relationships across the United States usually mean a shorter freight run, and paired chemicals, such as peroxide and its ferrous catalyst, ship on one order.
• Straight answers. How a product behaves in water, what it’s compatible with, and how to handle it. If one of ours isn’t right for your water, we’ll say so.

You don’t need every detail to start a conversation, but the more of this you have, the faster we can turn a real number:

• The product and the strength or form your design calls for
• Quantity per delivery and expected annual use
• Packaging that suits your storage and feed: pails, drums, totes, bags, or bulk
• Delivery address and receiving constraints, such as dock or liftgate needs
• Certifications and documents your permit or utility requires
• Your schedule

Common Questions

Does Hepure design water treatment systems? No. Your engineer, operator, or treatment provider designs and runs the process. We supply the chemistry and the product knowledge behind it: how each chemical behaves, how it’s handled, and how it ships.

Which of your chemicals are certified for drinking water? CarbPure TRA is certified to NSF/ANSI 61 and meets ANSI/AWWA B600-16. Our potassium and sodium permanganate, hydrogen peroxide, ferrous sulfate, and sodium hydroxide are certified to NSF/ANSI/CAN 60. Ask for the listings with your quote.

Is your activated carbon granular? No. CarbPure TRA and Fluxsorb RP are powdered activated carbons, made to be dosed into water and removed with the solids. They aren’t designed for fixed-bed filter vessels.

Can you deliver in bulk? For most of the line, yes: tankers for sodium permanganate, large pre-mixed potassium permanganate orders, Remotox, and emulsified vegetable oil; pneumatic bulk trailers for CarbPure TRA; bulk bags or bulk trailers for Fluxsorb RP. Sodium hydroxide ships in drums and totes, and ferrous sulfate in 50-lb bags.
