Reverse Osmosis

Did you know that reverse osmosis can remove dissolved salts from water? 

Reverse Osmosis is the best option to reduce or totally remove salinity in agricultural or industrial water. Our PLC controlled RO units require minimum commissioning time, are easy to operate and can be integrated into any industrial environment with MODBUS protocol.

Media Filtration

Media filtration is the most commonly used pretreatment process.

Water flows through one or more layers of granular media to remove suspended matter.

Oxidation plus filtration is also a common method to remove elements that in reduced form are dissolved like Iron or Manganese

Wastewater MBBR

Biological wastewater treatment is the most widely used method for removal of biodegradable materials from wastewater.

MBBR sewage treatment plants are the small footprint, simplicity of operation, ability to withstand weather flow variations and versatility and adaptability to remove not only BOD but also biological nitrogen with no operational attention or interruption.

Frequently asked questions

In ordinary filtration (called dead-end filtration), the feed moves towards the filter medium. All the particles that can be filtered by the filter settle on the filter surface so the filtration is not sustainable without removing the accumulated solids.

Reverse Osmosis uses a different type of filtration, called crossflow filtration, where the feed moves parallel to the filter medium to generate shear stress that avoids build-up at the membrane surface and creates a steady-state balance thanks to the sweeping effect. This requirement makes it necessary to separate the feed into two streams, a permeate (purified) flow and a concentrate flow that carries the concentrated contaminants that did not pass through the RO membrane.

As the concentrate feed gets more concentrated it has more osmotic pressure to overcome and a higher feed pressure is required to “push” water through the reverse osmosis membrane.

As a result of the cake layer balance on the membrane surface and the pressure limitations on the RO elements, each solution has a maximum practical concentration that determines the minimum percentage of water rejection and it will always be higher than zero.

All of them are common membrane filtration processes. Membrane porosity in micro, ultra and nanofiltration is too large for ion rejection but exhibit negligible osmotic pressure so operating pressures are usually much lower than in RO systems.

Membrane configurations and system designs are quite similar to those used in the single-stage RO process. The main difference between those processes is the membrane pore size:

  • Microfiltration: pore size around 0.1 microns, many microorganisms are removed but viruses remain in the water. Cannot remove dissolved substances.

  • Ultrafiltration: pore size around 0.01 microns, particles up to that size and many viruses are removed. Cannot remove dissolved substances.

  • Nanofiltration: pore size around 0.001 microns, most organic molecules and a range of salts (divalent ions) are removed. Nanofiltration pore is still slightly larger than the size of the common salt molecule (ClNa).

  • Reverse Osmosis: pore size around 0.0001 microns, removes most minerals and monovalent ions. While RO removes many harmful minerals, it also removes some healthy ones, this is why it is often remineralised.

Nanofiltration and RO remove Mercury, Lead, Heavy Metals, Arsenic, all germs and viruses and make hard water soft.

RO membranes will require periodic cleaning, typically one to four times per year, depending on the feed water quality, concentrate recycling and other factors. As a rule of thumbs, whenever the normalised pressure drop increases more than a 15% or the permeate flow decreases more than a 15% it is time to clean the membranes.

Fouling is the accumulation of the filtered particles on the membrane surface to the detriment of the filtering function. Scaling can be considered a type of fouling caused by the precipitation of dissolved elements.

The concentration factor in a RO system is the ratio between the amount of purified water (permeate flow) and the water that is sent to drain as concentrate. The more water you recover as permeate flow the higher the % of recovery and the higher % of salts in the concentrate stream.

As the degree of concentration increases in the concentrate stream, the solubility limits can be exceeded making salts precipitation on the membrane surface as scale.

Auto-flushing is a procedure in which, periodically, the permeate valve is closed and the concentrate valve is open to allow a high velocity flow flush away the scale built on the membranes surface. 

Clean-in-place (CIP) is a procedure to clean reverse osmosis membranes more deeply than auto-flushing in order to restore the permeability towards baseline levels. Performed periodically, it is a good option to reduce the chemical exposure risk to the service technicians.
