Magnesium oxide and Magnesium hydroxide for desulfurization

Some industrial processes are associated with significant sulfur level in their gaseous effluents.

As sulfur is related to acid rain issues, regulations on sulfur emissions are getting constantly tighter.

Magnesium oxide and Magnesium hydroxide play a major role in helping industries to face these more and more stringent requirements, while allowing to address the cost related issues in an optimized way.

The best solution for sulfur regulations issue

We offer a solution which is safer, cheaper, simpler (no corrosion), than typical caustic soda or lime based solutions. Please contact us so that we discuss about our references, and your project.



Waste water treatment

Safe and easy Magnesium-based alkali for Waste Water Treatment


In wastewater treatment applications, a  Magnesium-based reagent is a major solution for environmental constraints :

  • phosphorus removal
  • pH neutralization


Magnesium for phosphorus removal

Magnesium oxide, Magnesium hydroxide or Magnesium chloride are also used for phosphorus removal in waste waters. Precipitation of phosphorus into struvite in easily achievable which can then be reused as a fertilizer. When substituting FeCl3 or AlCl3, no specific equipment required.

The reactive Magnesium oxide, Magnesium hydroxide or Magnesium chloride we provide offers reliable results. The reactivity and the stability of our product make them preferred choices in wastewater treatment applications.


Magnesium oxide in pH control

pH control is obviously a key parameter to achieve a steady level of performance in your waste water treatment process. Magnesium oxide or Magnesium hydroxide, as a powder or as a slurry offers an ideal alternative for pH control compared to the other alkalis such as lime or caustic soda.

It buffers at a pH of about 9 so there is no risk of a pH overshooting and the reaction speed is comparable to the other chemicals. It is also environmentally friendly, safe and easy to handle.

Immediate Advantages


Even more importantly, the quantities of Magnesium oxide or Magnesium hydroxide to achieve a given level of neutralization will be drastically reduced compared to quantities of lime or caustic soda for the same effect. That will translate immediately into easier operations.

But above all into a significant cost reduction for these operations. Our teams of specialists will perform with you a diagnosis of your process to propose the most convenient solution.

They will then validate it at the lab scale before accompanying you through the needed industrial scale trials. Do not hesitate on soliciting them !


More than a provider, we are also a partner


TIMAB Magnesium is able to handle the whole implementation of Magnesium based reactive in your installation. We offer a complete service, from effluent sampling for laboratory diagnosis to tailor-made doses prescription, thanks to chemical analysis plus technical and economical study.

We perform in our labs. We also offer a full support for the performance of the industrial trials which validate definitively the solution.

This setup is key to offer you an optimized solution for your process, with no investment on your side.

This has been proven by the excellent results we have been achieving in the following industries : dairy, cheese plant, public or industrial water treatment plant, breweries, pastries, slaughterhouses, paper mills…




Neutralization of wastewater

In all industrial processes requiring water, particular care is given to the treatment of wastewater before discharging it back into the natural environment.

In all cases, the pH is an important parameter for the good progress of the process and / or for the protection of the environment:

-> Before the biological treatment in wastewater treatment plant, whether it is integrated or communal, pH control is a sine qua non condition to ensure the effectiveness of biological treatment (pH 6 -6.5). Too high pH leads to a degradation of the bacteriological environment and therefore affects the treatment of organic matter.

-> At the entrance of metanisation When the plant is equipped with a methanizer, ph control is a paramount parameter for the proper functioning of this one. In fact, the acetogenesis and methanogenesis reactions are the most effective at a pH between 6.5 and 7.5.

-> Prior to release to the natural environment, wastewater must meet controlled criteria to comply with regulatory standards. The pH of the wastewater must be neutralized in order to adapt to the pH level of the natural water (pH 6.5-8.5).


An alternative to soda for neutralization

  For all these applications, caustic soda is still the reagent most commonly used for its neutralizing power. Nevertheless, this product is more and more questioned because it has several notorious disadvantages. Indeed, sodium hydroxide NaOH, more commonly called caustic soda, is officially classified as a corrosive product. This involves risks for equipment, for the environment, and for humans. The handling of this reagent therefore requires the implementation of numerous safety measures.

TIMAB  Magnesium offers an exclusive alternative: liquid magnesium hydroxide, more relevant in terms of:

-> safety: Magnesium hydroxide is a totally safe product. Its safety is recognized for equipment, man and the environment.

-> economy: Our reagent being more efficient, the necessary doses are less important. This implies reduced consumption and therefore a reduction in the cost of reagents for neutralization of wastewater. In addition, the price of our raw material is much less volatile than that of soda.

-> efficiency: more effective neutralization power. 


A much more effective neutralization

By the nature of its components, our Magnesium hydroxide is a reagent whose alkaline power is significantly higher than that of soda.

According to theoretical calculations, Magnesium hydroxide neutralization power is twice as effective as soda (2.42 vs 1 in comparison with 30% soda)

During our factory tests, we were able to verify the neutralization potential of our Magnesium hydroxide, confirmed by recent trials in a plant in the agri-food sector (results on demand).

Our Magnesium hydroxide is in the form of milk, compatible with existing facilities. Switching from one to the other does not require any material investment, either for a test or for permanent installation. It is a non-hazardous reagent, easy to use. Our engineers will define with you the most appropriate dosage, depending on your installation, the nature of your effluents and your technical constraints.

TIMAB Magnesium is positioned as a key player for the success of your neutralization.

The only partner in Europe to offer this innovative product for a safer and more efficient wastewater treatment.

We also have wastewater treatment solutions in the US and in Asia. Feel free to ask our local team about it !
