Germkil RO Membrane Sanitizer

Description

Product Description: RO Membrane Sanitizer

This is a high-purity disinfectant solution used to eliminate microbial growth within the RO system. Unlike standard cleaners, this germicidal formula penetrates the cell walls of microorganisms to ensure the system is sterile. It is also commonly used as a “Preservation Liquid” when the RO plant needs to be shut down for a long period.

✅ Advantages

Complete Sterilization: Kills 99.9% of bacteria, viruses, and algae that survive standard cleaning cycles.

Prevents “Bio-Film” Re-growth: By killing the bacteria at the source, it prevents the quick return of slimy bio-films.

Long-Term Preservation: If your RO plant is going to be closed for more than 48 hours, this chemical prevents the water inside the membranes from “rotting” or smelling.

Non-Oxidizing (Usually): Most membrane-grade germicides are non-oxidizing, meaning they are safer for the membrane material compared to harsh chlorine.

DM Water Purity: Being blended with DM water ensures no new minerals are introduced during the sterilization phase.

🛠️ How to Use

Sanitization is typically the final step after the Acidic and Alkaline cleaning cycles are complete.

System Preparation: Ensure the membranes are already cleaned and flushed.

Dilution: Mix the sanitizer with RO permeate water in the CIP tank. (Follow the specific dilution ratio provided on your label, usually 0.1% to 0.5%).

Circulation: Pump the solution through the membranes for 30 to 45 minutes.

Soaking (Crucial): For full sterilization, let the membranes soak in the solution for 1 to 2 hours.

Note: If preserving the membrane for shutdown, leave the solution inside and close the valves.

Final Flush: Before starting the RO for production, flush the system for at least 15–20 minutes to drain, ensuring no germicide remains in the product water.

❌ Disadvantages & Risks

Rinse-Out Time: It can take a long time to completely flush the chemical out. If not flushed properly, the product water might have a chemical taste or smell.

Handling: Even though it is not as aggressive as HCl, germicides are toxic. They can cause skin irritation and should never be ingested.

Frequency: Over-sanitizing can sometimes lead to premature aging of certain types of membrane spacers.

Disposal: You must check local environmental laws before draining large amounts of germicidal waste into the sewer.

💡 The Complete “Cleaning Sequence”

If you are doing a full maintenance of your RO system, this is the correct order to use all the chemicals we discussed:

Antiscalant: (Used daily during normal operation).

Hypochlorite: (Used in pre-treatment to keep raw water clean).

Acidic Descaler (HCl/Citric): (To remove hard scales).

Alkaline Cleaner (NaOH): (To remove organic slime).

Sanitizer (Germicide): (The final step to kill any remaining bacteria).
