New technology that effectively removes contaminants

Norlex Systems has developed an advanced oxidation technology that safely and effectively disinfects and removes contaminants from wastewater. It is a highly cost-effective technology that significantly reduces the amount of excess sludge.

Our aquatic environment is under pressure. It is exposed to more and more contaminants, which occur in unnaturally high concentrations and represent an ever-increasing risk of pollution.

In Denmark, there is a great deal of focus on this pollution, and as a natural consequence, the regulations for wastewater treatment have been tightened. Therefore, it is crucial that wastewater treatment is optimised and streamlined.

Norlex Systems has continued to work on this and has introduced Norlex Systems Intense Oxidation® to the market, which is a completely new bubble technology for water purification of particularly high quality. The benefits of choosing this technology are quite clear:

5

It is a 100% chemical-free technology.

5

The ultrafine bubble technology breaks down contaminants.

5

The amount of excess sludge is significantly reduced.

NORLEX Systems Intense Oxidation® – innovative bubble technology

Norlex Systems Intense Oxidation® is a purification method based on a unique technology, which uses an oxidising gas to decompose the substances. It is an Advanced Oxidation Process (AOP) system whereby organic pollutants become oxidised and thus harmless.

The oxidising gas is injected into the wastewater as ultrafine nanobubbles, and when it meets contaminants, an effective decomposition process begins. The gas breaks down existing molecular structures, and the small bubbles attach to particles of contaminants in the wastewater. These particles are then carried to the surface and form a slurry layer that is skimmed off.

In this way, technology is able to remove contaminants in wastewater with incredibly high efficiency. Testing of the system shows particularly good results in the reduction of PAHs, phenols, pesticides and similar components.

This non-chemical purification technology can also use air (or any gas) to separate solids from the water, and results show that the total suspended solids are reduced by more than 99%.

A more efficient technology

The chemicals currently used for coagulation and flocculation in wastewater treatment can be quite expensive. In some cases, they can even prevent a good result from the treatment process as a whole, and, in addition, conventional chemical technologies generate quite a lot of excess sludge. With Norlex Systems Intense Oxidation®, the amount of excess sludge is significantly reduced. Therefore, there is subsequently less work with and lower costs from excess sludge, because the amount is so small.

The organic load of the waste stream is also significantly reduced – e.g., COD can be reduced by up to 80% and BOD by 50%. This helps in the subsequent treatment of the waste stream, which reduces the need for chemicals for the final purification.

Wastewater treatment with unprecedented efficiency

Wastewater treatment with unprecedented efficiency
Today, Norlex Systems’ bubble technology is used in the part of the water purification process where the sludge is separated from the water. When the oxidising gas is combined with a flotation system, an unprecedented efficiency is achieved.
In the flotation system, the liquid is separated into a sludge phase containing the unwanted contaminants and a “clean-water” phase by means of flotation.
The advantages of using Norlex Systems’ flotation during wastewater treatment are many:

N

Does not require specially trained staff.

N

The system is monitored by PLC alarms, which can be sent by text to the operator.

N

Requires less space than biological purification systems.

N

No secondary pollution caused by chemical additives etc.

N

Can decompose/transform highly degradable organic compounds.

N

Removes colour from wastewater.

N

Generates clean sludge without chemical residues.

Norlex Systems can combine the flotation system with a sludge drainage solution, so that the sludge volume is minimised.

The bubble technology will set new standards

Norlex Systems’ Intense Oxidation Flotation (IOF) will set new standards in the following areas:

N

In the removal of pollutants in water purification and wastewater treatment.

N

In pre-treatment of wastewater prior to biological purification, where it reduces wastewater chemicals and energy consumption.

N

In cooling towers where the product disinfects, so the consumption of biocides is reduced significantly.

N

For separation of oil and water, where Norlex’s IOF is able to remove even very small oil droplets in water and can simultaneously remove solutes.

N

In food production, for the washing of meat, fish, fruit and vegetables. The shelf life of food washed in water from Intense Oxidation treatment will be significantly longer because the microscopic bacteria that degrade the food are removed.

N

In aquaculture, for increased oxygenation of reservoirs. Nanobubbles of oxygen will significantly increase the availability of oxygen for fish and shellfish in reservoirs. At the same time, bubbles will have a disinfecting effect that greatly increases the water quality.

N

In membrane cleaning and prevention of fouling. With an Intense Oxidation system, fouling in membrane systems can be significantly reduced as biofilm and other organic substances decompose.
