    Product Overview

    Preservative and dechlorination agent for water treatment.

    Detailed Description

    Sodium Metabisulphite supplier in Oman - Global Chemicals LLC provides food grade and technical grade SMBS for dechlorination, food preservation, and industrial applications in Muscat, Sohar, Salalah. Our sodium metabisulfite effectively removes residual chlorine and serves as antioxidant. Sodium Metabisulphite (SMBS, Na₂S₂O₅) is an important reducing agent and dechlorination chemical in Oman's water treatment, food, and wine/brewing sectors. In RO membrane systems, SMBS is the standard dechlorination chemical dosed upstream of RO membranes — because polyamide thin-film composite (TFC) membranes are irreversibly damaged by chlorine, even at low concentrations. Oman's extensive seawater RO desalination infrastructure at Ghubrah, Barka, Sohar, Al Qurayyat, and Salalah all rely on SMBS dosing for membrane protection. In food preservation, SMBS (E223) prevents browning, inhibits microbial growth, and extends shelf life of dried fruits, juices, and processed foods. In the brewing industry, SMBS sterilises equipment and prevents microbial contamination. Global Chemicals LLC supplies SMBS technical grade (for RO and water treatment) and food grade (E223) in 25kg bags. SDS and CoA with every delivery.
