OCH CL -201  ALKALINE MEMBRANE CLEANER

OCH CL 201 is a specially formulated cleaner for removing heavy metal fouling, bio-foulants, slime, polysilicic scales and other colloidal/particulate based foulants from reverse osmosis membranes. OCH CL 201 is also effective in removing calcium, silt, organics and metal sulfides.

 Features:

Highly effective & easy to handle concentrated liquid

Effectively restores membrane performance deteriorated due to scaling

Harsh on foulants but gentle on membranes

GENERAL SPECIFICATIONS:-

pH as such                     : > 11

Specific Gravity             : NA

Appearance                    : colorless liquid

Water solubility             : Complete

 DIRECTION OF USE:-

OCH CL 201 should be fed in CIP tank to prepare solution for offline cleaning. The dosage and frequency of addition depends upon the severity of fouling/scaling, typical dosages are mentioned below:-

Routine offline cleaning: OCH CL 201 is normally recommended at a dose level of 2% solution to be circulated for one hour at low velocity followed by 1-2 hours soaking then one hour high velocity circulation and permeate flushing. It is used against calcium, metal oxides, bio-foulants and other foulants.

Typically it is recommended to be used before acidic or biocidal cleaning for better efficacy, however actual cleaning programme may vary and will be suggested by our OCH representative after carefully examining your system.

OCH CL -202  ACIDIC MEMBRANE CLEANER

OCH – CL 202 is especially formulated for Removing Calcium Carbonate, Calcium Sulfate, Iron, Inorganic Scaling, Metal Hydroxides, Minerals, and Colloidal Material (Inorganic Type)

OCH CL -202 is a stable, non-foaming, surfactant-free, acid compound specifically designed for TF type RO membranes and membrane systems. It is effective on many types of common mineral scales associated with membrane fouling. It is effective at low temperatures up to 120°F.

Features:

Highly effective & easy to handle concentrated liquid

Effectively restores membrane performance deteriorated due to scaling

Harsh on foulants but gentle on membranes

 GENERAL SPECIFICATIONS:-

pH as such                     : < 2

Specific Gravity             : 1.10 – 1.20  

Appearance                    : colorless liquid

Water solubility             : Complete

 Direction for use

OCH CL 202 should be fed in CIP tank to prepare solution for offline cleaning. The dosage and frequency of addition depends upon the severity of fouling/scaling, typical dosages are mentioned below:-

Routine offline cleaning: OCH CL 202 is normally recommended at a dose level of 3-4% solution to be circulated for one hour at low velocity followed by 1-2 hours soaking then one hour high velocity circulation and permeate flushing. It is used against calcium, sulfates, hydroxides and other foulants.

Typically it is recommended to be used after alkaline or biocidal cleaning for better efficacy, however actual cleaning programme may vary and will be suggested by our OCH representative after carefully examining your system.
