Reverse Osmosis Chemicals

Dew is world-leading reverse osmosis technology specialists. Our RO chemical products are based on advanced formulations and include RO membrane cleaners, flocculants, Dechlorinators, biocides, scale inhibitors, and antiscalants. Our advanced formulations have been developed specifically for the international desalination and reverse osmosis sectors and offer significant safety, cost, environmental and operational performance benefits over traditional products.

Reverse Osmosis Membrane Cleaners

The use of high-quality membrane cleaners is an important part of any reverse osmosis plant program. There are advantages in cleaning membranes at an early stage of fouling, as irreversible damage can occur when cleaning excessively fouled membranes.

Reverse Osmosis Antiscalants

Dew offers a range of advanced technology RO Antiscalants for superior scale prevention performance, product stability across a wide pH range, and excellent membrane compatibility.

RO Biocides

Our range of high-performance biocides is suitable for use in reverse osmosis systems to control biofouling in reverse osmosis membranes.

RO De-Chlorinators

Chlorine removal from the feed water prior to it entering the RO membranes. This is because chlorine will destroy polyamide thin-film composite membranes and even trace amounts of free chlorine can cause oxidation damage, especially in the presence of metals such as iron.

RO Flocculants

To reduce the Silt Density Index (SDI) so that it does not exceed the maximum specified by the membrane manufacturer. We offer SDI test instruments that allow the accurate monitoring and analysis of the Silt Density Index.
