Coagulant Selection Chart: PAC vs Aluminium Sulfate vs Ferric Sulphate vs Ferrous Sulphate Coagulant choice sets the dose, the pH correction, the sludge volume and the clarity you can achieve. This page pulls the four common water-treatment coagulants into one selection chart so you can shortlist before you jar-test. The four are polyaluminium chloride (PAC),

How to Buy Polyaluminium Chloride (PAC): Specs, Al2O3 and Basicity PAC (polyaluminium chloride, CAS 1327-41-9) is not a single specification – two suppliers can quote “PAC” at very different quality and price. To buy it well you need to fix three things: the Al2O3 content, the basicity and the grade (drinking water or industrial). This

Polyaluminium Chloride (PAC) in Water Treatment in Africa Africa’s water sector is expanding fast – municipal supply, industrial wastewater, mine water and reuse. Polyaluminium chloride (PAC, CAS 1327-41-9) suits that environment well: it works across a wide pH range, is effective in cold water, forms flocs quickly and needs less pH correction than alum, which

PAC vs Aluminium Sulfate vs Ferric Sulphate: Choosing a Coagulant Coagulant choice drives the whole treatment train: dose, pH correction, sludge volume and the clarity you can achieve. The three workhorses are polyaluminium chloride (PAC), aluminium sulfate (alum) and ferric sulphate. This article compares them on the things that matter in practice – pH window,

Water Treatment Chemicals: How the Pieces Fit Together Water and wastewater treatment is a sequence of chemical steps, and buying it product-by-product leads to mismatched doses, incompatible grades and missed savings. This page is the overview of the water-treatment chemicals we supply, why each is used, and how they work together – from coagulation and

Sodium Metabisulfite Export to Africa: Grades, Packaging, Ports and Documents Buying sodium metabisulfite (Na2S2O5, CAS 7681-57-4) for an African mine, utility or food processor is mostly a logistics and paperwork exercise once the specification is fixed. This article covers the grades and specifications you should confirm, the packaging and container options, the ports and trade

Sodium Metabisulfite for Water Treatment in Africa Water treatment is one of the biggest uses of sodium metabisulfite (Na2S2O5, CAS 7681-57-4), and Africa is one of the regions where the demand is growing fastest. Municipal utilities, desalination and reverse-osmosis plants, mines and food processors all use it to remove chlorine and control oxidation. This article

Buying DDAC: What Matters DDAC (didecyl dimethyl ammonium chloride, CAS 7173-51-5) is a liquid cationic biocide supplied as an 80% solution. Buying it well means confirming the identity and active content, checking residual amine and pH, choosing the right form for your process, and respecting the regulatory and compatibility rules that apply to quaternary ammonium

DDAC vs Benzalkonium Chloride: An Overview DDAC (didecyl dimethyl ammonium chloride) and BAC (benzalkonium chloride) are the two best-known quaternary ammonium biocides, and they are frequently compared, substituted and blended. Both are cationic, both are broad-spectrum antimicrobials, and both follow the same incompatibility rules — but their structures differ, and that difference shapes their performance
