Dewindia is world leading reverse osmosis technology specialists. Our RO chemicals 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 are 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 offer a range of advanced technology RO Antiscalants for superior scale prevention performance, product stability across a wide pH range and excellent membrane compatibility.
Our range of high performance biocides are suitable for use in reverse osmosis systems to control biofouling in reverse osmosis membranes.
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.
To reduce 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 Silt Density Index.
Microbiological Testing & Membrane Autopsy
We perform extensive range of microbiological testing and analyses. We also offer membrane autopsy and analysis services that include bacteriological examination, light microscopy, electron microscopy, and polymer degradation tests.
