Why We Need CIP

This report contains the CIP for the RO plant at EEAP. The RO plant

CIP required when the surface of RO membrane is subjected to

fouling by foreign materials which may be present in the field water

such as Hydrates of metal oxides, Calcium precipitates, Organic and

biological matters. (The term” fouling” here includes the buildup of all

kinds of layers on the membrane surface, including scaling.

CIP of RO plant mostly required on the Basis of following 3 points:

• When the ∆p across the membranes increases 10%

• Permeate flow decreases 10%

• TDS increases abnormally.

In normal operation, the membrane in reverse osmosis elements can

become fouled by suspended solids, microorganisms, and mineral scale.

These deposits build up during operation and cause loss in water output or

salt rejection, or both. Regular cleaning of the membrane elements

minimizes the loss of performance and extends membrane life.

Membrane cleaning systems are designed to be used with any RO system

to clean membranes without removing them from the system. Our cleaning

systems are provided with hoses and quick disconnect fittings to allow easy

connection to the membrane system.

CIP Activity

• RO plant CIP activity started at 0900 hrs. at 1st March

• First of we fill the cleaning tank with permeate water.

• Chemical used for CIP are Genesol 703, Genesol 37, Genesol 30

• Take samples for Analysis before the CIP

• Before CIP starts note down all the parameters of RO plant. • After that starts the first bath with Gensol 703 for 02 hours by adding

10 kg.

• In this bath 15 minutes are for circulation and fifteen minutes for

soaking.

• After that starts the 2nd batch by adding 15 kg chemical time required

for that bath was 4 hrs.

• During this cleaning we frequently note down the ph. of solution, that

was alkaline solution and PH remains from 10.5 to 12

• After this complete flushing of system take place.

• After that we started the acidic cleaning with Genesol 37.

• Total time required for this activity was 05 hrs.

• 30 minutes for circulation and 40 minutes for soaking.

• After that bath with acidic chemical complete flushing was done,

• The RO plant cleaning activity was end at 00:30 hrs.

• Then we take RO back in service and note down its parameters after

cleaning.

• Took the sample for lab analysis after cleaning.

Data Comparison before and after CIP

Data and LAB Results

Conclusion

• After CIP the completion it was observed that the permeate flow is

increased from 10 GPM to 20 GPM.

• ∆p across the membrane is decreased from 105 psi to 95 psi.

• Permeate TDS are also decreased.

Recommendation

It is recommended that when a RO machine is going to shutdown,

carefully consideration must be paid. And For the membrane storage

procedure in order to minimize the potential for micro biological growth in

the system.

Preservation

Short term shut down of an RO system (24-48 hours) generally does not

require special membrane storage procedures. The RO should be cycled

(run in operational mode) for at least 15 minutes every 24-48 hours to

reduce the potential for bio-growth and stagnation within the system. Some

systems use a permeate flush during shutdown. This type of cycling will

allow the system to remain “operationally” ready, and it will allow for a

slightly longer time between flush cycles.

For prolonged storage (i.e. several days to several months), the following

procedures are recommended. These procedures will help protect and

preserve the elements from bacterial growth. The elements can be left in

their housings or unloaded and stored separately.

Typically, one of the following lay-up solutions is used depending upon

application

Regulatory limitations, preference, and chemical availability:

1. 0.5 to 1.0% sodium bisulfite or Biocide.

Preservation procedure

The following procedure is recommended for RO storage with biocide

solution.

• Prepare the appropriate strength sodium bisulfite or biocide solution

in the Cleaning tank by diluting with permeates water.

• Circulate the solution through the RO system for 15 to 20 minutes.

• When the RO system is filled with this solution, close the valves to

retain the solution in the RO.

• Repeat Steps 2 and 3 with fresh solution every 15 days

• When the RO system is ready to be returned to service, flush the

system to drain until the

• Permeate water meets quality specifications, then return the machine

to service

Dear Faisal Farooq

As per our telephonic conversation I have sent you the procedure for RO

cleaning and Ro preservation, kindly review these and reply me if you want to add

some points or any suggestion .we are using Gensol membrane cleaner chemicals

for RO CIP.

Also please confirm your visit at plant sight tomorrow for ROpreservation activity.
