Do you know why many industries are turning to Abrizan’s specialty solutions for MED systems after years of using generic materials?⚠️

The use of specialty chemical solutions in multi-stage desalination (MED) systems not only prevents corrosion and scale, but also reduces operating costs by up to 25% and doubles the life of the equipment. Abrizan’s Mitreh brand products are designed with customized formulations, precisely based on the unique chemical challenges of each MED system.

Why are generic solutions not enough for MED systems?

MED systems operate in conditions of high temperatures, extreme salt concentrations and variable pH. Generic chemicals:

• Decompose at high temperatures
• React adversely with sulfate or silica ions
• Do not provide adequate corrosion protection for copper alloys or stainless steel

In contrast, specialty water treatment solutions are formulated with three key factors in mind—feedwater composition, equipment alloy type, and operating pattern.

⚙️ Four key advantages of Mitreh solutions in MED systems

➕ 1. Targeted prevention of complex scale types

MED systems typically encounter a combination of scales:

• Calcium carbonate (CaCO₃)
• Calcium sulfate (CaSO₄)
• Silica (SiO₂)
• Magnesium hydroxide (Mg(OH)₂)

Mitreh brand anti-scale and anti-scale products contain dispersant polymers and crystal inhibitors that:

• Inhibit the formation of scale nuclei
• Keep fine particles in suspension
• Effective even at high TDS concentrations (up to 70,000 ppm)

If you want to know what type of scale is dominant in your system, read the article [Scales and corrosion in MED desalination plants].

➕ 2. Intelligent multi-faceted corrosion protection

In MED, corrosion can occur from three main sources:

1. Oxygen corrosion (due to air leakage)

2. Acid corrosion (in low pH conditions)

3. Stress corrosion cracking (in sensitive alloys)

Mitreh thermal system anti-corrosion products:

• Contain film-forming inhibitors (such as molybdate and nitrite)
• Combined with liquid oxygen scavengers (such as substituted hydrazine or carbozide)
• Compatible with copper alloys, 316L stainless steel and titanium

✅ Technical note: In MED systems, the use of nitrite-free anti-corrosion agents is recommended to prevent the formation of nitrosamines (carcinogens) — and Mitreh offers such formulations.

➕ 3. Control biofouling without damaging equipment

Biofilms grow in the colder MED effects (usually effects 4 and above). Using chlorine or hypochlorite in these systems is dangerous because:

• It causes pitting corrosion in stainless steel
• It reacts with ammonium ions to produce toxic trihalomethanes

In contrast, non-oxidizing “mitreh” biocides (such as DBNPA and stabilized glutaraldehyde) and biodispersants:

• Remove biofilm from the surface
• Operate without increasing the risk of corrosion
• Stable at 40–60°C

➕ 4. Compatibility with chemical wash processes

Even the best antifouling program sometimes requires periodic washdown. Mitreh products are designed as an integrated ecosystem:

• Mild acid washes (citric or acetic based) for carbonate deposits
• Acid-based descalers for sulfate and silica
• Alkaline detergents for grease and biofilm
• Neutralizers and degreasers after washing

This coordination prevents side reactions between the different materials. For the correct implementation of this process, see the [MED Desalination Chemical Wash Steps] guide.

How do waterborne solutions increase ROI?

Many people think that specialty materials are “more expensive.” But in reality:

Real data: A refinery in southern Iran reduced steam consumption by 12% and unplanned shutdowns by 70% after replacing generic materials with Mitreh thermal antifouling.

❓❓❓FAQs about using eluent solutions in MED❓❓❓

❓ Are these materials compatible with our RO or MSF systems alongside MED?

Yes. Mitreh formulations are also optimized for combined systems (such as MED + RO). For example, their antifoulings do not clog the RO membrane and do not cause problems in the desalination unit.

❓ Do we need to change the dosing system?

No. All Mitreh products are supplied as ready-to-use solutions or soluble powders and are compatible with standard dosing systems.

❓ How do we make sure that these materials are suitable for our system?

Abrizan Company offers free laboratory services and consultations:

• Feedwater analysis
• Sediment type identification
• Alloy compatibility testing
• Operational simulation in the laboratory

If you observe symptoms such as decreased production or increased temperature, first read the article [Signs of the need for chemical flushing of MED desalination plants].

❓ Why do large industries choose Abrizan?

• ✅ Domestic formulation: No dependence on imports
• ✅ 24/7 technical support: On-site engineering team
• ✅ ISO 17025 laboratory: Data-driven, not guesswork
• ✅ Experience in sensitive industries: oil, gas, power plants, petrochemicals

Also, Abrizan is the only manufacturer in Iran that offers specialized scale removers for hydrocarbon compounds and acid-base descalers with integrated corrosion inhibitors — features that are vital in oil units connected to MED.

✍️ Conclusion: Expertise is the Difference

In complex systems like MED, one size does not fit all. Mitreh’s specialist solutions are not only designed based on water chemistry, but also formulated with a deep understanding of the industry’s operational challenges. This combination allows industries to not only pay less but also significantly increase system reliability.
