About EP Water

EP water has a number of synonyms, including:

• EP purified water
• Pharmaceutical water
• EP pharmaceutical water
• Pharmaceutical purified water
• pH.eur water
• Water EP
• EP H2O

EP water is a grade of water that has been produced to meet the requirements of the European Pharmacopoeia (EP), an internationally-recognised standard whose specification guarantees a certain level of quality.  EP water is one of a number of Pharmacopoeia waters, including USP water (United States Pharmacopoeia), BP water (British Pharmacopoeia), and JP water (Japanese Pharmacopoeia).

Properties of EP Water

Each grade of water will differ slightly but all waters produced to these standards are very low in impurities, such as heavy metals, nitrates, chlorides, and sulphates, and will meet certain conductivity and pH specifications.

EP water has a conductivity of less than 5.1 microsiemens, nitrates of less than 0.2 ppm, heavy metals of less than 0.1 ppm, TVC of less than 100, chlorides of less than 70 ppm, sulphates of less than 250 ppm, pH between 5-8, residue on evaporation of less than 100 ppm, and it passes the oxidisable substances test.

EP water is recognised worldwide and has many applications including product testing, analytical work and manufacturing.  Many companies specify the use of EP water in their processes to ensure that a specific level of quality is adhered to, particularly where unwanted trace elements or minerals could affect the outcome.

How We Manufacture EP Water

When we manufacture EP water, we use deionised water as a feedstock in a twin pass reverse osmosis (RO) system.

RO is a type of ultrafiltration, and once the water is in this system, it’s continuously moving through the ring main and the storage tank. This means that it’s always passing through the RO and then an ultraviolet (UV) sterilisation stage. The water is then bottled, typically in 25L containers and 1,000L IBCs, or used in process. We also carry out weekly testing to ensure compliance with the current specifications for both EP and USP purified water.
