RO Water Plant:

Brackish Water:

If a source of brackish water is available, this may be used as the feed source for the RO Plant. This will result in very substantial capital cost and operating cost savings compared to seawater RO Plant. The key to using brackish water, however, is that the TDS of the water source should remain relatively constant over time.

In some cases the pumping of the brackish water causes lowering of the groundwater table, with the result that sea water intrusion may occur and an increase of the TDS of the water source over time. An RO Plant designed to treat brackish water will either work inefficiently or stop working as the TDS increases. In addition, when there is seawater intrusion, the original groundwater source may be ruined, and it will take years for it to regenerate.

Seawater Source. The development of a good seawater source for the RO Plant is perhaps the single most important factor in ensuring the success of the RO system. There are three main types of seawater sources, and many variations. The best one will depend on the local site and ocean conditions, and the local geology.

RO Plant Itself:

Water from the seawater source is pumped under pressure to the sand filters. If biological fouling or chemical scaling are expected, chemicals may be dosed upstream of the sand filters. For a seawater system, approximately one-third of the water pumped to the plant will become product water (permeate) and about two-thirds will become brine (concentrate).

The sea water passing through the sand filters then passes through a 5 micron pre-filter which provides protection for the RO membranes.

Post Treatment. Water produced by an RO Plant must be treated further to balance the pH and ensure the water will not cause corrosion in the water distribution system. There are several ways of achieving this.

Mineral Filter. In this first type of system, the water passes through a pressure vessel containing minerals which dissolve into the water. The minerals, which resemble crushed coral, adjust the pH and add hardness to the water to minimize corrosion in the water distribution system. This type of system is a simple and reliable means of treating the product water.

Chemical Dosing. A second means of treating the product water is to dose chemicals such as lime or soda ash into the water to adjust the pH and add hardness. This type of system requires more operator attention than a mineral filter, and is more appropriate for larger systems.

Membrane cleaning methods:

There are several different membrane cleaning methods, such as forward flush, backward flush and air flush.

 

  • When forward flush is applied, membranes are flushed with feed water or permeate forward. The feed water or permeate flows through the system more rapidly than during the production phase. Because of the more rapid flow and the resulting turbulence, particles that are absorbed to the membrane are released and discharged. The particles that are absorbed to membrane pores are not released. These particles can only be removed through backward flushing.
  • Backward flush is a reversed filtration process. Permeate is flushed through the feed water side of the system under pressure, applying twice the flux that is used during filtration. When the flux has not restored itself sufficiently after back flushing, a chemical cleaning process can be applied.
  • During a chemical cleaning process, membranes are soaked with a solution of chlorine bleach, hydrochloric acid or hydrogen peroxide. First the solution soaks into the membranes for a number of minutes and after that a forward flush or backward flush is applied, causing the contaminants to be rinsed out.
  • A newer cleaning method is the so-called air flush or air/ water flush. This is a forward flush during which air is injected in the supplier pipe. Because air is used (while the water speed remains the same), a much more turbulent cleaning system is created.

 

Forward flush

When forward flush is applied in a membrane, the barrier that is responsible for dead-end management is opened. At the same time the membrane is temporarily performing cross-flow filtration, without the production of permeate.

The purpose of a forward flush is the removal of a constructed layer of contaminants on the membrane through the creation of turbulence. A high hydraulic pressure gradient is in order during forward flush.

Backward flush

When backward flush is applied the pores of a membrane are flushed inside out. The pressure on the permeate side of the membrane is higher than the pressure within the membranes, causing the pores to be cleaned. A backward flush is executed under a pressure that is about 2.5 times greater than the production pressure.

Permeate is always used for a backward flush, because the permeate chamber must always be free of contagion. A consequence of backward flush is a decrease in recovery of the process. Because of this, a backward flush must take up the smallest possible amount of time. However, the flush must be maintained long enough to fully flush the volume of a module at least once.

Air flush or air/ water flush

Fouling on the membrane surface needs to be removed as effectively as possible during backward flush. The so-called air flush, a concept developed by Nuon in cooperation with DHV and X-flow, has proved to be very useful to perform this process. Using air flush means flushing the inside of membranes with an air/ water mixture.

During an air flush air is added to the forward flush, causing air bubbles to form, which cause a higher turbulence. Because of this turbulence the fouling is removed from the membrane surface.

Chemical cleaning

When the above-mentioned cleaning methods are not effective enough to reduce the flux to an acceptable level, it is necessary to clean the membranes chemically.

During chemical cleaning chemicals, such as hydrogen chloride (HCl) and nitric acid (HNO3), or disinfection agents, such as hydrogen peroxide (H2O2) are added to the permeate during backward flush. As soon as the entire module is filled up with permeate, the chemicals need to soak in. After the cleaning chemicals have fully soaked in, the module is flushed and, finally, put back into production.
