OptiClean A CIP chemical
What is CIP?
- CIP is the abbreviation of Clean In Place, which is a cleaning method for cleaning equipment without changing the position of the equipment.
- Chemical cleaning of the membrane system is mainly divided into acidic cleaning and alkaline cleaning. Acidic cleaning agents are used to remove inorganic contaminants, including iron pollution, while alkaline cleaning agents are used to clean organic contaminants, including microorganisms. When preparing the cleaning agent, it is best to use the product water of the membrane system to prepare the cleaning solution. Of course, in many cases, qualified pretreated effluent can also be used to prepare the cleaning solution. The raw water may have a large buffering capacity, and more cleaning agents may be needed to reach the specified pH value. The pH of acid cleaning is about 2, and the pH of alkaline cleaning is about 12.
- OptiClean™ A is a low pH (acidic) powdered cleaner combining select chelants and solubilizing agents to remove metal hydroxides, carbonates, sulfates, calcium phosphates and other similar scales. OptiClean™ A provides broad spectrum scale removal, and is ideal for situations where limited information is available on foulant make-up. Combining OptiClean™ A with an alkaline cleaner such as OptiClean™ B for particulate and organic removal provides a comprehensive cleaning.
Advantage of OptiClean A CIP chemical
- Readily dissolvable powdered cleaner provides efficient shipping and handling
- Phosphate-free formula to reduce negative impact on the environment
- Buffered pH to maintain optimum cleaning performance throughout cleaning cycle
- Best results when used in conjunction with either OptiClean™ B or Lavasol™ 2
- Classified for use in membrane systems producing drinking water (ANSI/NSF/CAN Standard 60)
Application of OptiClean A CIP chemical
- For use on reverse osmosis (RO), nanofiltration (NF), ultrafiltration (UF) and micro-filtration (MF) membranes
- Formulated to dissolve inorganic precipitants from the membrane surface
- To chelate and remove oxides of iron and aluminum from the membrane surface
When do I need to clean the RO membrane?
When you notice any ONE of the following changes:
- NPF (Normalized Permeate Flowrate) = Permeate flow rate reduced by 10 – 15%
- NDP (Normalized Differential Pressure) = Differential pressure from 10 – 15%
- NSP (Normalized Salt Passage) = The amount of salt passing through the membrane increases from 10 – 15%
The benefits of the above indicators bring:
- If these limits are exceeded for a long time, it may not be possible to recover as before!
- Helps you plan your membrane cleaning activities proactively
- Determine your plant’s standard membrane washing frequency and stick to it
How to use organic OptiClean A CIP chemical
The standard CIP diagram is as follows:
- The CIP chemical solution flow operates in the same direction as the filtration process. CIP chemical solution circulation time is from 30-90 minutes. Recommended CIP for each Stage. Maximum flow is 152 liters/minute for 8 inch RO membrane and 38 liters/minute for 4 inch RO membrane. Maximum cleaning pressure is 60 psig (4.2 bar).
- In case the RO membrane is heavily clogged, at the initial CIP, it is recommended to separate the stream and discharge 10 – 20% of the membrane cleaning solution stream to avoid residues that have separated from the membrane and then stick to the membrane surface. When re-operating the RO system, the permitted water stream after filtering must be discharged to ensure that residual membrane cleaning chemicals are completely removed from the system.
- Rinse the membrane with RO water before operating the system again
# Note: In case of using multiple types of OptiClean chemicals to clean the membrane, absolutely do not mix the chemicals together but must CIP each type to avoid mixing them together to change the properties of OptiClean. Flow depends on the type of pump used. If the flow is not enough, it can be divided into CIP for each stage. Pressure below 3 bar. During chemical immersion, to maintain a stable temperature the flow rate must be low
Tips for cleaning membranes quickly:
- To shorten the stability time of salt, clean with alkaline chemicals with high pH (OptiClean B) first, and acidic cleaning chemicals with low pH (OptiClean A,D,S) later.
- Choose the right membrane cleaning chemical according to the type of scale.
- You should change and adjust CIP parameters when the water color changes and the pH changes as follows: When you see the pH increase more than 0.5 during the inorganic cleaning process (add chemicals to stabilize the pH within the specified range of producer). When you see the pH decrease more than 0.5 during the organic cleaning process (add chemicals to stabilize the pH within the manufacturer’s specified range).
- Report should be recorded after CIP (date/stage/cleaning conditions (performance, steps, time), cleaning performance).
- You should check the filter cartridge before CIP.
Choosing the right membrane cleaning chemicals is very important because frequent and poor cleaning will shorten the life of the membrane, and sometimes the wrong choice of cleaning chemicals can stain the membrane again. faster and reduces membrane life. Cleaning will be more effective if it is properly adjusted to each individual film condition.
