Osmosis is the phenomenon of lower dissolved solids in water passing through a semi-permeable membrane into higher dissolved solids water until a near equilibrium is reached. Reverse Osmosis (RO) is a membrane process of purification which removes most of the the total dissolved solids (TDS) in water by reversing the natural process of osmosis. Pressure is applied to a TDS-concentrated solution against a semi-permeable membrane, causing pure water to diffuse through the membrane. RO has become an important...

In desalination plants it is of great importance for the operation of the entire plant that the pre-treatment of the water is good before the salt is to be removed. For reverse osmosis (RO) desalination plants a good pre-treatment is essential for avoiding membrane fouling, resulting in reduced water production and increased operational costs.

AQQA is the ideal system to act as a prefiltration for Reverse Osmosis desalination systems. It is installed directly after the intake from the ocean. By taking out particles > 0,1 µm, the sensitive R.O. membranes can be protected and work much more reliable with a higher output.

Microorganism and bacteria control is increasingly an important topic of discussion in the oil and gas industry. Inadequate disinfection and treatment of well injection water and stimulation fluids, used in the recovery of oil and gas has been proven to lead to a host of negative consequences, including: - Souring the well with hydrogen sulphide gas H2S, Microbiological induced corrosion, Loss of fluid stability during injection., Plugging of the well, Damage of equipment and components (e.g. RO membranes,...Premium
It may seem paradoxical, but processes used to clean water actually also create wastewater. Reverse Osmosis creates clean water by forcing the water through a semipermeable membrane that filters out many moleclues. The problem is with the water that`s left, that does not pass through the membrane, which has an extremely high concentration of salts and minerals. This water is called RO reject or reverse osmosis concentrate. Reverse Osmosis reject can sometimes equal as much as half the volume of the...

The purpose of de-chlorination is the removal of free chlorine and combined chlorine compounds from potable water, as supplied by municipal water supplies. Chlorine will oxidize the surface of thin film composite polyamide membranes, causing the membrane to lose its ability to repel or reject salts. As a result, the membranes used in Reverse Osmosis (RO) or Electro-deionisation (EDI) systems will exhibit shorter lifetimes when exposed to chlorine in the water they are treating and membrane manufacturers will...Premium

Reverse Osmosis or RO is a system used to produce an ultra-high quality of water with use of membrane. Reverse Osmosis plants are required in many production processes. Damage to these high quality membranes can easily be caused if no pre-filtration is in place to protect the system from high loading, this can result in extremely high costs of repairs, ranging from tens of thousands to millions, not to mention the loss of production to a company if as a result of plant failure production has to be...

Reverse Osmosis (RO) technology has been used for years in various industries to separate dissolved solids from water by forcing the water through a semi-permeable membrane. RO is also commonly used to purify drinking water and desalinate seawater to yield potable water. The water and other molecules with lower molecular weight (specific weight of molecules allowed to pass through is dependent on the selected membrane) pass through the micropores in the membrane, yielding a purified water stream called the...
