Pharmaceutical water treatment for the industry

Current challenges in the pharmaceutical industry

The pharmaceutical industry is constantly facing new challenges. The issue of corporate sustainability, the importance of patient safety, new regulations and requirements as well as the need for a flexible production infrastructure are currently defining the requirements for water treatment.

Into the future with customised solutions

As an experienced manufacturer of water treatment systems, we understand these challenges. We offer flexible services for your existing systems and solutions for customised new systems. A partnership that not only lasts today, but also tomorrow.


Quality engineering and service for your pharmaceutical water

Purified water plays an irreplaceable role in pharmaceutical production. As one of the few raw materials produced directly on site, it is subject to strict quality requirements and regulations. We have specialised in meeting the specific requirements of the pharmaceutical industry for purified water (PW) and water for injection (WFI).

Our aim is not only to offer technologically leading solutions, but also to fulfil the highest quality and safety requirements.

We focus on the specific design requirements for water treatment plants as well as the strict requirements for their implementation and operation in order to ensure microbiological purity in production at any time.​

Successes that speak for themselves

"We have been relying on Herco's system technology for 19 years now and can testify to the reliability of the system technology and Herco's service. During this time, not a single membrane change has been necessary on the reverse osmosis system. This is possible thanks to the unique dead-zone-free design of the reverse osmosis system, the reliable maintenance and the particularly good quality of the sophisticated technology."

Questions and answers relating to pharmaceutical water

What is pharmaceutical water treatment?

Pharmaceutical water treatment is the process of purifying water to prepare it for pharmaceutical production. This includes the removal of contaminants such as organic compounds, microorganisms and ions. The treated water is used as an ingredient in medicines or to clean equipment which is utilised in the manufacture of medicines.

Why is the treatment of pharmaceutical water important?

Pure water is a critical raw material in the production process of the pharmaceutical industry. The purity of water is crucial to ensure the safety and efficacy of medicines and microbiological purity, as well as to avoid contamination that could lead to production errors or health risks.

What are the quality requirements for pharmaceutical water?

Pharmaceutical water must fulfil strict regulatory standards, which can vary depending on the application and country. Common standards include the regulations of the United States Pharmacopeia (USP), the European Pharmacopoeia (EP) and the Japanese Pharmacopoeia (JP). These set limits for specific contaminants and microbiological purity.

How does the treatment of pharmaceutical water work?

The cleaning process usually begins with pre-filtration to remove large particles. Methods such as reverse osmosis are then used to remove dissolved solids, followed by processes such as UV irradiation or ozonisation for disinfection.

What are the differences between the various treatment methods?

The different methods of water treatment, such as distillation, reverse osmosis and ion exchange, are used depending on the specific water quality requirements and the desired level of purity. While distillation is a very effective but energy-intensive method, reverse osmosis offers a more cost-effective solution for the removal of ions and microorganisms.

Where are the technologies for pharmaceutical water treatment used?

The technologies are used worldwide in pharmaceutical production systems. These include areas that require high purity standards, such as the production of injections, infusions and other sterile medicines.
