Acid Membrane Cleaner for RO Membranes for Removal of Calcium Carbonate Scale Fouling

5 lb Pail of AM-11-5 Acid Cleaner for RO Membranes


In normal operation, the membrane sheet in reverse osmosis membrane elements can become fouled by suspended solids, microorganisms, and mineral scale. AM-11 Acid RO membrane cleaner is specifically formulated to Calcium Carbonate, Mineral Scale, Hardness, Iron, Barium, Sulfate, and other scaling from RO membranes.

Carbonate scale fouling can be identified by the following symptoms:

  • The RO Membrane will likely exhibit low permeate flow
  • The RO Membrane will likely exhibit low salt rejection
  • The membrane may feel heavier than normal

Regular cleaning of the membrane elements minimizes the loss of performance and extends membrane life. Membrane elements should be cleaned whenever the normalized permeate water output rate drops by 10% from its initial flow rate (the flow rate established during the first 24 to 48 hours of operation), when salt passage in the product water increases over 5-10%, or when normalized pressure drop across the membrane increases by 10-15%.

AM-11-5 RO membrane acid cleaner is sold in powder form in a 1 gallon pail. Chemical mixing instructions, membrane cleaning instructions, product specifications, and SDS/MSDS sheets are included with each container. AM-11 is not considered DOT hazardous for shipping.

Applied Membranes, Inc. acid membrane cleaner is a result of over 35 years of hands-on experience of water quality engineers and chemists. WaterAnywhere offers technical expertise and assistance in troubleshooting and cleaning of RO membranes to give you an optimum system performance.

Benefits of Regular Use of AMI Acid and Alkaline Membrane Cleaners

  • Maintains system performance and product water quality at a higher level
  • Reduces Operating Costs by reducing energy requirements to reach required product flow
  • Reduces Maintenance costs by prolonging membrane life, and reducing strain on other components in the system

RO Membrane Cleaning Sequence:

It is recommended to start with the alkaline cleaning then follow with the acid cleaning after the system has been flushed.
1. Alkaline Cleaning - AM-22 (if required)
2. FLUSH
3. Acid Cleaning - AM-11
4. FLUSH

Note: Acid cleaning may be performed alone, but alkaline cleanings should always be followed by an acid cleaning after the system has been flushed.

Interactive Dog Toy
Color: Orange
My 100 lb shephard/golden mix likes this toy but she tends to get agitated with it. I have to keep an eye on her because she destroys toys in record time. The only complaint I really have is once she gets interested and plays for a long time it needs to be charged and she doesn't want me to take it to be charged. Wish the charge lasted a little longer or there were two of the inner parts so one could charge while she is playing with the second one. The plastic ball could be made of rubber so the teeth marks don't show up.

Bouncy, not hard, and good value.
Style: Fetch Balls (Pack of 10), Size: 2.5 inch
Great balls for the ball launcher and not rockhard like some of the solid rubber balls. These have great bounce, and because of the two holes, they make a fun whistling noise as they fly through the air. My dogs love them and they are a good value. By the way, if you throw them too hard, they will go through chain-link and no climb fence because they squish a bit!

Excellent dog balls — safe design and very durable
Style: Fetch Balls (Pack of 3), Size: 2.5 inch
These fetch balls from Amazon Basics are fantastic, and my dog absolutely loves them. One of the biggest reasons I prefer these over other brands is the hole that runs through the center of the ball. This is a very important safety feature: if a dog were to accidentally get the ball stuck in the back of the throat, the hole allows air to pass through. That small detail could literally make a life-saving difference. Aside from the safety benefit, they bounce well, are easy to clean, and hold up to a lot of playtime. They’re firm but not rock-hard, and my dog goes crazy for them. Great value, great quality, and a thoughtful design. Highly recommended for dog owners who want a safer alternative to standard solid rubber balls.

Great ball for heavy chewers
Style: Assorted Balls (Pack of 3), Size: 2.5 inch
Great toy for my Doberman. She chews through tennis balls in about 15 minutes but these are very durable. She likes to chase them but also just chew on them.
