About Aluminium Sulphate

Aluminium sulphate is a coagulant used to aggregate fine suspended solids so they can be settled and removed. It is used in swimming pool clarification, potable water treatment, wastewater and effluent treatment, and in paper and textile processing. Non-ferric grade is supplied where the application is potable.

Frequently asked

Questions we get about Aluminium Sulphate

What does RNJ Trading supply?
Swimming pool and water treatment chemicals. The range covers chlorine sanitisers — SDIC granules and tablets, TCCA 90, calcium hypochlorite and sodium hypochlorite — alongside pH and alkalinity correctors, a coagulant for water clarity, and cyanuric acid stabiliser. Everything is available in pail, drum and bulk-bag formats. The full list, with grades and pack sizes, is on the products page.
What is SDIC?
SDIC — sodium dichloroisocyanurate, also written NaDCC or dichlor, CAS 2893-78-9 — is a stabilised chlorine donor supplied as a white granule or a pressed tablet. It is one of the standard chlorine chemistries used in swimming pools and in water disinfection. We supply it in 56% and 60% available-chlorine grades, in two particle sizes, and in tablets from 1 g to 200 g.
What is the difference between SDIC, TCCA and calcium hypochlorite?
They are three different chlorine chemistries. SDIC and TCCA are chlorinated isocyanurates and are stabilised, meaning they contain cyanurate; calcium hypochlorite is unstabilised and contains calcium instead. They differ in available chlorine, in how quickly they dissolve and in whether their solution is acidic or alkaline — the typical values for each are published on its product page. Which one suits a given installation is a decision for the person responsible for that water system.
