Water Treatment Chemicals

Glutaraldehyde (CAS 111-30-8) is one of the most effective and versatile biocides in industrial water treatment and oilfield operations. Its broad-spectrum activity, compatibility with brines and performance across a wide pH range make it a first-line choice for controlling bacteria — including sulfate-reducing bacteria (SRB) — in cooling water, injection water and produced-water systems. This

Glutaraldehyde (pentanedial, CAS 111-30-8) is a bifunctional dialdehyde with a unique combination of biocidal, crosslinking and tanning properties. It is the standard high-level disinfectant for medical instruments, a water treatment biocide, a leather tanning agent and a key intermediate in specialty chemistry. This article covers the manufacturing chemistry, the specifications, the applications and the safety

PolyDADMAC (polydiallyldimethylammonium chloride, CAS 26062-79-3) is a liquid cationic polymer sold in a range of solids contents, viscosities and purity grades. Because it has no single “purity” number, buyers often struggle to compare quotes. This purchasing guide covers the specification sheet, the COA, packaging and storage, and the supplier checklist for PolyDADMAC. 1. Reading the

In the paper mill, the wet end is a constant chemical balancing act: fibers, fines, fillers and dissolved anionic substances all compete for retention, drainage and cleanliness. PolyDADMAC (polydiallyldimethylammonium chloride, CAS 26062-79-3) is one of the most widely used cationic polymers in papermaking — as an anionic trash catcher (ATC), a retention aid component, and

PolyDADMAC (polydiallyldimethylammonium chloride, CAS 26062-79-3) is one of the most widely accepted synthetic organic coagulants in drinking water treatment. Its approval under standards such as NSF/ANSI 60, its effectiveness at low dose, and its minimal sludge production have made it a standard tool in municipal plants worldwide. This guide explains how PolyDADMAC works in drinking

PolyDADMAC (polydiallyldimethylammonium chloride, CAS 26062-79-3) is one of the most widely used cationic polymers in water treatment, papermaking and personal care. Its unusual ring-forming polymerization chemistry, very high charge density and regulatory acceptance for drinking water make it a unique product in the flocculant family. This article covers the manufacturing process, the properties that matter,

Polyacrylamide (PAM, CAS 9003-05-8) is one of the most important water-soluble polymers in industry, and its manufacturing process — from acrylamide monomer to the finished flocculant — determines everything about the final product: molecular weight, ionic type, residual monomer, dissolution behavior and price. This article describes the industrial manufacturing process of polyacrylamide in technical detail,

Polyacrylamide (PAM, CAS 9003-05-8) is sold by dozens of suppliers in a bewildering range of grades. Buyers who focus only on price often end up with the wrong ionic type or an inconsistent product that performs differently from batch to batch. This purchasing guide covers the specification sheet, the COA, packaging, storage and the supplier

Most people meet polyacrylamide (PAM, CAS 9003-05-8) as a water treatment chemical, but agriculture is one of its oldest and most valuable uses. Applied to soil or irrigation water, PAM binds soil particles, cuts erosion, improves infiltration and clarifies irrigation runoff. This guide explains how agricultural PAM works and how to apply it correctly. 1.
