Legionella Risk in Hotels over COVID Lockdown

Biocides & Disinfectants, Case Studies, Knowledge Base, Legionella, News

Evidence is emerging of the significant increase in Legionella growth in premises offering overnight accommodation where the usage/occupancy was affected during the 2020/21 COVID lockdown. The information strongly suggests that there is a potentially increased risk of Legionella exposure for those people staying in hotels or similar accommodation when the sites come back into full use in 2021. Legionella infections include the potentially fatal Legionnaires’ disease, an atypical form of pneumonia, with a high mortality rate.

A Study of Activ-Ox Chlorine Dioxide effect on Hotel Legionella Control in lockdown As the UK emerged from the first lockdown and businesses started to reopen, the challenge of maintaining good microbiological control, during this Lockdown period became apparent. To study this, Feedwater carried out comparative data analysis to evaluate the impact of chlorine dioxide…

Coagulation and Flocculation – Process Fundamentals

Closed System Treatment, Cooling Water Treatment, Facilities Management, Knowledge Base

Suspended matter in raw water supplies is removed by various methods to provide water suitable for domestic purposes and most industrial uses. The suspended matter can consist of large solids which settle by gravity alone without any external aids and ‘non-settleable’ material often colloidal in nature. Removal is generally by coagulation, flocculation and sedimentation. The…

What is Corrosion?

Boiler Water Treatment, Closed System Treatment, Cooling Water Treatment, Facilities Management, Knowledge Base

Corrosion is the reversion of metals to their natural state by oxidation, an electrochemical reaction that causes a loss of the metal structure. The site where corrosion occurs is called a corrosion cell. Corrosion may take a variety of physical forms. General corrosion occurs when corrosion cells are spread broadly across large surface areas; pitting…

Choosing your Closed System Corrosion Inhibitor

Closed System Treatment, Facilities Management, Knowledge Base

Corrosion inhibitors for Closed, heating and cooling water systems Corrosion inhibitors are an essential to ensure the longevity and efficient operation of your closed heating or cooling water system. The two main types of treatment for closed systems are nitrate or molybdate based corrosion inhibitors. In certain circumstances using a Tannin based inhibitor may be a better choice if,…
