When designing a commercial drinking water system using ultraviolet (UV) light for disinfection, you will need to know the local regulations, how to determine flow rates, what options may be required and whether you need pre-treatment. When speaking about commercial establishments, I am referring to restaurants, daycare centers, schools, hospitals, parks and other entities that serve the public.
Overview of state regulations, determining flow rates, system options and pre-treatment requirements
Finding the right housing depends a lot on the application in which the housing will be used. Being familiar with your water filtration needs as well as researching the benefits of various types of housing will help you make the right decision.
The following is part two of a two-part article.
The cartridge often is thought of as the heart of a filter system. However, the cartridge operates within a housing and even a cartridge that is perfectly matched to the application won’t perform adequately if it’s not also matched to a housing that meets the same application requirements. Specifying them together as an integrated system is the best way to assure they provide optimal performance.
Over the years, water quality has noticeably deteriorated worldwide. This decline in water quality stems from the extreme demand on very limited natural resources. Various principles of filtration are used in many applications to improve the general quality of the water that is being treated. Along with screen filters, coagulation/filtration, neutralizing filters, oxidizing filters, clairifying filters and carbon filters are other treatment methods that may be used.
Various filter technologies stretch limited natural resources for drinking water
Legionellosis, the disease caused by Legionella spc., is common, though most people would guess it is extremely rare. Outbreaks of Legionellosis, defined as a cluster of three or more cases in a single locale, occur regularly in the United States and much of the developed world. Outbreaks have been reported in Australia, Holland, Thailand, Japan, England and many other countries. In the U.S., the Center for Disease Control (CDC) receives reports of 1,000 cases of Legionellosis annually.
