Chemtex’s RO Antifoulant is a super-threshold RO membrane antiscalant and antifoulant which is able to stabilize a wide range of supersaturated salt solutions, thereby preventing the precipitation on the membrane surface.

It reduces the risk of scaling and eliminates the use of hazardous acids, resulting in efficient plant operation with highest possible conversion rate.

It is a very effective antiscalant for waters with LSI upto +2.5, Iron upto 1.2ppm in reject, High SDI.

Key Features and Benefits

• Effective scale inhibition
• High recovery rate
• Low chemical dosage
• Cost Effective
• Effective Iron fouling control by sequestration
• Reduced frequency of membrane cleaning
• Compatible with all types of membranes
• Completely organic and biodegradable

Chemtex's High pH Silica Antiscalant is a chemical compound that is useful for preventing silica fouling in the RO membrane. The silica antiscalant is a alkaline product and is very much suitable for being added to drinking water system.

RO Antiscalant, manufactured by Chemtex Speciality Limited, is a liquid antiscalant for RO membrane system. Using Chemtex’s RO Antiscalant controls inorganic scales of calcium, magnesium, barium, stronium, fluoride, iron and silica. Chemtex’s RO Antiscalant ensures above 80% reduction in scaling tendencies if used continuously.

It is a very effective antiscalant for waters with LSI upto 2.7, Iron upto 1.4ppm in reject, Silica upto 175ppm (or mg/l), High SDI. It is compatible with ALSTAFLOC series of coagulant and flocculants (polyelectrolytes).

Chemtex’s RO Antiscalant keeps RO capacity close to design, and minimizes shutdowns and membrane cleaning cost.

Key Features and Benefits

• Effective scale inhibition
• High recovery rate
• Low Chemical dosage
• Cost Effective
• Effective Iron fouling control by sequestration
• Reduced frequency of membrane cleaning
• Compatible with all types of membranes
• Completely organic and biodegradable

Chemtex’s High pH Membrane Cleaner is an alkaline liquid product for cleaning of contaminants like oils,organic compounds, silica scales and biological slimes and films from RO/NF/UF membranes.

Chemtex’s High pH Membrane Cleaner also contains organic dispersants that helps to break down colloidal clay deposits and imparts better efficacy to biocides by penetrating into films.

Key Features and Benefits

• High pH formulation for excellent system clean up
• Removes oil, silica scales, organic matter and bio-foulants
• Very effective even in low concentrations
• Excellent dispersing properties for quick and easy removal of soil
• Low foaming cleaner for ease of use in recirculation method
• Concentrated cleaner and Cost effective
• Easy to use and handle for its liquid state
• Biodegradable

Application and Dosage
Chemtex’s RO Cleaning Chemical should be diluted with DM or RO permeate water to prepare a stock solution of 2-5%v/v. This solution should be re-circulated through the membranes for 2-4 hours (including a soak time of 30-60mins) and flush out the system with DM or permeate water till equal pH is achieved at both ends of pass. For detailed cleaning procedure, please refer the Procedure Sheet provided.

Note: Shake the container well before use. Replace the solution with new one if the cleaning solution becomes severely fouled and turbid.

In multi-pass systems, best results can be achieved if each pass is individually cleaned

For severely fouled or choked membrane a higher concentration upto 10% v/v should be used after cleaning with ALKRO CL27 (High pH membrane cleaner).

Chemtex’s Ro Dechlorination Chemical Is An Excellent Ro Feed Water De-Chlorinator. It Is A Concentrated Liquid For The Elimination of Residual Chlorine Prior To The Ro Membrane System.

This Is Necessary Because Some Membrane Materials Such As Tfc Membranes Can Be Irreversibly Damaged By The Presence of Strong Oxidizing Agents Such As Chlorine.
