The Ultimate FAQ Guide for Membrane Cleaning Systems.

Continuous feed water treatment using perforated membranes can potentially result in clogging or fouling of the respective membranes. To thwart the consequential deterioration in performance, membrane-based treatment systems necessitate membrane cleaning systems.

Frequent cleaning prolongs your membrane’s lifespan and membrane cleaning skids make the process easier. In this article, we provide expert answers to frequently asked questions on our systems.

➣What is a Membrane Cleaning System?

A membrane cleaning system is simply a device used to clean reverse osmosis, Nanofiltration, ultrafiltration, and microfiltration membranes within their system housing. With a system, you do not have to pull apart your membrane from its housing structure for cleaning or unclogging.

RO CIP skids utilize varying membrane cleaning mechanisms to effectively clean the membranes. Common methods deployed include backward, forward, and air-flush membrane cleaning mechanisms. For optimal results, chemical cleansing (using HCL, HNO_3, and H₂O₂) is deployed.

Membrane cleaning skids have varying tank capacities and can clean different amounts of pressure vessels simultaneously.

➣What is the Proper Membrane Cleaning Process?

To clean your membranes, you have the liberty of choosing your ideal membrane-cleaning methodology from the following processes.

Backward flush.

Cleaning via backward flush is simply reversing the filtration process. Pressure (almost 2 times the ordinary filtration flux) is applied to force the permeate backward thereby flushing out the accumulated constituents.

Forward flush.

Forward flush makes use of rapid flow to generate turbulence that forces constituents stuck on the membrane out. Forward flush is however incapable of flushing out elements trapped in the membrane perforations calling for the backward flush.

Air flush.

Air flush is often deployed in tandem with the forward flush. To increase the turbulence, the air is injected during the forward flush thereby forming bubbles, which elevate the turbulence. Consequently, the pollutants trapped around the membrane’s surface are flushed out.

Chemical cleaning (acids or alkaline).

Chemical cleaning involves the addition of disinfectants like hydrogen peroxide or cleaning agents like nitric acid and hydrogen chloride. The solution containing the permeate and the cleaning chemicals is circulated through each stage, adhering to the recommended flow rate.

➣What is the Significance of Membrane Cleaning Systems?

Over time, contaminants ejected by the semi-permeable membrane accumulate on its surface resulting in a clogged membrane. Consequently, the system’s flow rate begins to depreciate resulting in lower productivity. Predictive membrane cleaning seeks to mitigate the repercussions of a clogged membrane by undertaking cleaning before the system exhibits a lower production rate.

Reactive membrane cleaning on the other hand seeks to arrest the decrease in performance by cleaning the membranes after there has been a noticeable change in performance levels. However, both approaches ensure that your membrane-based treatment system continually treats water at a high flow rate.

➣What are the Various Applications of Membrane Cleaning Skids?

Membrane cleaning skids are applicable in virtually all membrane-based filtration systems. Irrespective of your system’s size or the number of membranes, you can deploy a membrane cleaning system to unclog, clean, or descale your membranes.

They make certain your system’s high production standards are continually met. In addition, membrane cleaning units save you money on the untimely replacement of membranes. They are ideal for use in seawater reverse osmosis desalination systems, Nanofiltration units as well as ultrafiltration plants.

➣What is the Flow Rate of Membrane Cleaning Systems?

NEWater’s standard membrane cleaning systems have a flow rate ranging from 8-210 gallons per minute. This is approximately 1.8 to 48 meters cubed per hour. The flow rate of a system depends on the operating pressure and consequently determines the productivity of the membrane cleaning system. You can contact our specialists for further information on the ideal flow rate for your membrane cleaning skid.

➣What Factors Should I Consider When Purchasing a Membrane Cleaning Skid?

Existing membrane cleaning systems are specifically made for use in certain membrane-based systems. Therein it is crucial that you do some background checks on the prospective skids and their suitability for your respective application. Underneath, is a summary of key aspects for your consideration before you purchase a membrane-cleaning skid.

• The number and size of pressure vessels were necessitated.
• The type of system you intend to clean (Nanofiltration, reverse osmosis, microfiltration, or ultrafiltration).
• The cleaning process and cleaning agent.
• How the membrane cleaning system is joined to the water treatment plant.

➣Which Membranes are Viable for Treatment by a Membrane Cleaning System?

Membrane fouling occurs in all membrane-based water treatment systems. For sustained, top-notch performances, regular cleaning, descaling, and unblocking of the semi-permeable membranes are necessitated.

During filtration, some of the alienated contaminants remain trapped on the membranes’ pores and surfaces.  To prevent membrane fouling from occurring or progressing, NEWater manufactures membrane cleaning skids suitable to clean the following types of water treatment membranes.

• Reverse osmosis membranes.
• Microfiltration membranes.
• Ultrafiltration membranes.
• Nanofiltration membranes.

Back to the guide ⇪

➣What Causes Membrane Fouling?

Membrane fouling is often a consequence of three causes:

Soiling.

Soiling is an aftermath of colloids like clay, silt, and silica being entrapped on the membrane’s surface. It is highly common in seawater RO membranes and is often resolved using chelating agents.

Adsorption.

Adsorption (also referred to as absorption) is a result of biological elements such as proteins, microorganisms, fats, and greases forming biopolymers on the membranes. To flush out the biopolymers, an appropriate chemical agent is deployed.

Precipitation.

Precipitation on the other hand is a consequence of the over-saturation of the solution. The contaminants are forced to alienate from the solution, consequently sticking to the membrane’s surface.

➣What is the Lifespan of Reverse Osmosis Membranes?

Typical reverse osmosis membranes have a life expectancy ranging from 3 to 7 years contingent upon the application. Other influences that determine the lifespan of an RO membrane include; the quality of pretreatment, frequency, and effectiveness of membrane cleaning, design, and the membrane’s quality.

The quality of feed water also significantly affects the lifespan of an RO membrane. Seawater is likely to evoke the buildup of a biofilm around the membrane’s surface due to the high concentration of dissolved salts and microorganisms.

Groundwater, on the other hand, is likely to foul the membrane by prompting scaling as a result of high calcium, magnesium, and iron concentrations. Failure to enforce predictive or reactive membrane cleaning considerably lowers the life expectancy of the RO membrane.

➣When is it Necessary to Clean Membranes?

There are two approaches to membrane cleaning, predictive and reactive cleaning. Our specialists advocate for predictive membrane cleaning because it prevents the repercussions of a fouled membrane. Our engineers recommend you clean your membrane whenever the following indicators are exhibited.

• When the system exhibits a 10% decrease in permeate flow rate.
• When the operating pressure drops hikes by 10 or 15%.
• When the impurity passage rate surges by 5 to 10%.

➣What are the Basic Components of Membrane Cleaning Systems?

RO CIP skids are so effective because of the high-quality components they are made of and the effective consumables they utilize. Below we briefly summarize the basic components that make up a superior and cost-efficient membrane-cleaning skid.

Mixing tank.

Containers with varying capacities are key components of membrane cleaning skids given they provide an avenue for preparing and storing the cleaning agent. Most mixing tanks possess a mechanical mixer, which facilitates sufficient dilution. When cleaning an 8-inch vessel with 6 elements, a mixing tank with a capacity of 60 gallons is recommended.

Cartridge filter.

In between the pressure vessels and the pump, there is often a filter responsible for keeping large constituents off the membrane-cleaning skid.  The filter pores are often 10-20 micron-sized and replacement should be enforced once the pressure drop hits 10-15psi.

Connectors.

Additionally, membrane cleaning systems have connectors that link them to the membrane-based system. It is recommended that each stage of vessels should be cleaned separately at a relatively high flow rate.

Other components include a means of heating, thermometer, PH reader, and a pump.
