Water Treatment Chemicals

Sodium Bicarbonate in Flue-Gas Treatment and Water Treatment Beyond food and feed, sodium bicarbonate (CAS 144-55-8, NaHCO3) has two important environmental uses: as a dry sorbent for removing acid gases from flue gas, and as a pH and alkalinity adjuster in water and effluent treatment. Both exploit the same chemistry – bicarbonate neutralises acids and

Chloramine T (CAS 127-65-1): A Solid Chlorine-Releasing Disinfectant and Oxidising Agent Chloramine T is the sodium salt of N-chloro-p-toluenesulfonamide – a white crystalline powder that releases active chlorine and is used both as a disinfectant and as an oxidising reagent. It sits between the harsh liquid hypochlorites and the modern halogenated hydantoins: a solid, comparatively

Phosphoric Acid in Water Treatment and Industrial Cleaning Phosphoric acid (CAS 7664-38-2) is a mild, food-grade-capable acid that does two distinct jobs in water and industry: it conditions water (as a pH adjuster and a phosphate corrosion inhibitor) and it cleans and treats metal (as a mild descaler and a phosphating acid that leaves a

Phosphoric Acid Supply to Africa: Water Treatment, Food and Industrial Use Africa is a major phosphate producer in its own right, so the phosphoric acid that matters for most buyers there is not fertiliser-grade bulk – it is the technical and food-grade acid used in water treatment, food and beverage processing, and metal treatment. This

Sulfamic Acid Supply to Africa: Packaging, Ports and Documents Africa runs some of the world’s most demanding descaling and cleaning duties – copper and gold plants, utilities, food and beverage factories – and sulfamic acid suits them because it is a solid, safe-to-store acid that works without the chloride risk of hydrochloric acid. This page

Sulfamic Acid Price and Supply: What Drives the Cost Sulfamic acid is a commodity descaler and cleaning acid, and its price swings more than most mineral acids because it is made from urea – a feedstock tied to the fertiliser and natural-gas markets. This page explains the cost structure and how to buy well, without

Sodium Metabisulfite Price and Supply: What Drives the Cost Sodium metabisulfite (CAS 7681-57-4) is a commodity, and its price moves with the cost of its raw materials, energy and freight – not with the season you happen to buy in. Understanding what drives the number is the fastest way to buy well. This page explains

Sodium Metabisulfite for Chromium(VI) Reduction and Metal Treatment Hexavalent chromium (Cr(VI)) is toxic and tightly regulated, and the standard way to remove it from wastewater is to reduce it to the far less harmful trivalent form, Cr(III), and then precipitate it as the hydroxide. Sodium metabisulfite (CAS 7681-57-4) is one of the reagents used for

Sodium Metabisulfite vs Bisulfite vs Sulfite: Choosing a Reducing Agent Sodium metabisulfite, sodium bisulfite and sodium sulfite are all sulfur-based reducing agents, and buyers often treat them as interchangeable. They are not: they differ in active sulfur content, form, solution pH and stability, which changes the dose and the choice. This page compares the three

Flocculant Selection Chart: PAM vs PolyDADMAC vs Polyamine by Charge and Application Organic flocculants build coagulated particles into flocs that settle, float or dewater. Choosing the right one is mostly about charge and molecular weight – after coagulation has done its job. This page pulls the three main organic flocculants (polyacrylamide, PolyDADMAC and polyamine) into
