Hospitals store large volumes of water to distribute through long and complicated pipework. Cleaning the water at this initial stage has benefits for an entire hospital's water network.
The quality of the water used in the Automated Endoscope Reprocessors (AER) is paramount for the cleanliness of endoscopes. This is particularly important at the final rinse stage where the disinfectant chemicals are washed off and bacteria is not introduced from this water. It is therefore critical that clean water is used.
Water delivered at point-of-use (POU) throughout the hospital should be safe for cleaning, washing and drinking as outlined in L8 and HTM 04-01. Bacteria such as legionella and pseudomonas can cause a serious threat to patient's health and if not properly controlled, can cause potentially lethal infections and diseases.
The purity of the water used in dialysis is critical in order to effectively clean the blood of patients. Impurities, chlorine and chloramines in the water and system can cause health problems with the patient, subsequently this requires an increase in medicines used for treatment.
One of the most important areas for water quality in a hospital. Water is used to clean instruments and critical components of systems used during operations and procedures on patients. Water for the water disinfectors should be softened. Water used in the production of clean steam or treated steam for the autoclaves, must be of very high purity.
Water used by patients for mouth rinsing should be bacteria free. Bench-top sterilisers are fed with water which must be free of impurities, as this can affect the instruments and cause scale build-up on expensive equipment. Water must also be bacteria free to prevent cross contamination of instruments. This area is considered critical as it falls under the guidance given in HTM 01-05.
Facilities and services make up a large part of a hospital and require filtration equipment to ensure that they function as expected. Such facilities include, kitchens, air handling units, laundry and boilers.
- Efficient boiler and HVAC systems save money
- Scale free ovens reduces maintenance and improves food quality
- Sterile clothing reduces infections
