Reliable additives for boiler water, cooling circuits, membrane systems and waste water treatment in the chemical and pharmaceutical industries

Our additives are specially formulated for regulated industries. Each batch is supplied with full documentation and certificates of analysis so that operators can prove auditability according to GMP or FDA at any time. Additionally we offer:

• Traceability via batch numbers and laboratory certificates

• Digital reporting system for seamless documentation of dosing, monitoring and system parameters

• Validated dosing strategies that comply with strict production specifications
  This means that chemical and pharmaceutical companies can not only safeguard their processes, but also have access to complete data in the event of an audit.

Cooling water systems in the chemical and pharmaceutical industries are often hygiene-critical and must be operated continuously and reliably. With our additives, operators achieve:

• Legionella-free and hygienically safe systems thanks to highly effective biocides and bioinhibitors

• Clean heat exchanger surfaces thanks to hardness stabilizers and dispersants → Lower energy consumption

• Long-term corrosion protection for metallic system parts → Less downtime due to leaks

• Stable processes even at high temperatures, changing loads or aggressive raw water qualities

The result: predictable operational reliability, reduced energy costs and a longer service life for the systems.

Membrane systems (e.g. reverse osmosis) are often critical systems in the pharmaceutical industry, as they are used to produce process or ultrapure water. Even the smallest deposits can jeopardize product quality.
Our additives offer clear added value here:

• Antiscalants prevent deposits caused by hardeners, sulphates and silicates

• Special cleaning agents dissolve protein, biofilm and organic residues that occur in pharmaceutical processes

• Cleaning boosters shorten CIP cycles and minimize downtimes
  Practical example: By combining antiscalants and cleaning boosters, a pharmaceutical company was able to extend cleaning intervals from 4 to 7 weeks, resulting in considerable savings in operating costs.

In pharmaceutical plants, any unplanned downtime jeopardizes production safety, batch validation and delivery capability. Boiler systems (steam for sterile processes, clean rooms, autoclaves) and cooling water systems (air conditioning, reactor cooling, process water) are particularly critical.

Typical risks:

• Corrosion in boiler and cooling circuits → Leaks, contamination

• Scaling in heat exchangers → Loss of performance, waste of energy

• Biofouling → hygienic risk, validation problems (e.g. in cooling towers with product proximity)

ALMA AQUA process additives significantly reduce these risks:

• Oxygen binders and corrosion inhibitors prevent material damage in boilers, thereby avoiding downtimes caused by leaks.

• Hardness stabilizers and antiscalants keep heat exchangers free of deposits, ensure constant energy efficiency and prevent validation deviations in energy/temperature profiles.

• Biocides and bioinhibitors control microbial growth in cooling water systems, which is particularly important in order to comply with hygienic GMP requirements.

In addition, we supply complete batch documentation and monitoring reports that can be used directly as evidence in audits (GMP, FDA, EMA). This not only prevents technical failures, but also strengthens the regulatory safety of operations.

Wastewater from the chemical and pharmaceutical industries is among the most complex of all. It is often contaminated discontinuously (e.g. by batch processes) and contains mixtures of organic residues, solvents, salts, heavy metals and nutrient imbalances. Typical problems:

• Highly fluctuating COD/TOC values → Overloading of biological stages

• Low biodegradability (high proportion of poorly biodegradable substances)

• Impurities such as surfactants or emulsions that impair flocculation and sludge stability

• High disposal costs due to poorly dewaterable sludge

ALMA AQUA process additives specifically address these points:

• Precipitants (e.g. iron or aluminum salts) remove phosphates, metals and colloidal compounds that would otherwise lead to unstable discharge values.

• Flocculants with precisely matched charge density ensure that even the finest particles are combined to form large, stable flocs - a prerequisite for reliable separation.

• Special sludge conditioning agents improve dewaterability → higher dry matter content, lower disposal costs.

• Trace substances and nutrient doses stabilize the biological residual stage by achieving an optimal C:N:P ratio.

The key in the chemical and pharmaceutical industry lies in a dynamic, adaptive additive strategy that compensates for load fluctuations. With our jar tests, pilot tests and online monitoring, we ensure that the wastewater quality remains reliably within the standard range - even with complex and changing loads.

In the chemical and pharmaceutical industries, energy and operating costs often account for a large proportion of total costs. Cooling water and boiler systems in particular are key consumers here. Even small deposits (1 mm of limescale or milkstone) can increase energy consumption by 10-15 %.

ALMA AQUA process additives specifically counteract this effect:

• Hardness stabilizers and antiscalants prevent crystal growth and keep heat exchanger surfaces clean.

• Corrosion inhibitors ensure a smooth surface without the formation of deposits caused by corrosion products.

• Defoamers stabilize boiler operation and prevent uneven steam formation.

By using these additives, operators in pharmaceutical industry projects have been able to stabilize their heat exchanger performance, increase energy efficiency and reduce CO₂ emissions. The added benefit: The measures can be measured immediately - by monitoring the approach temperature, efficiency or fuel consumption.

Pharmaceutical plants often use high-pressure boiler systems for steam generation - whether for sterilization, autoclaves or reactors. These systems often run 24/7 and are extremely sensitive to deposits and corrosion. Even minor faults can cause production stoppages and validation problems.

The conditioning strategy must therefore:

• Eliminate oxygen (oxygen binder) to prevent pitting and stress corrosion cracking

• Stabilize pH (alkalizing agent) to keep pipes and boiler walls in the optimum range

• Check hardness formers (hardness stabilizers, antiscalants) to prevent deposits on heating surfaces

• Ensure steam cleanliness (defoamer) to prevent foaming and product contamination

ALMA AQUA boiler additives are formulated precisely for these requirements and can be coupled with online monitoring so that operators receive real-time feedback on conductivity, pH and oxygen content. This not only maximizes operational safety, but also ensures auditability in GMP environments.
