Cactus UV purification systems are available for residential and light commercial use, and are engineered to reduce bacteria, cysts and most viruses to safe levels. The X-8 model is available for 8-gpm flow and the X-12 model works for 12-gpm flow. Air-cooled lamps and a standard anti-fouling system allow for a wider and more effective temperature range as well as minimized quartz fouling.
DUV Series UV water disinfection systems are designed for commercial applications from 7 to 25 gpm and feature a stainless steel treatment chamber, visual viewport for lamp operational status, heavy-duty ballast power supply and grounded power cord. The optional UV monitor provides a zero to 100% display of UV lamp intensity.
With its patent-pending secondary window and PTFE probe body, this new UV sensor is designed for long field life and ease of servicing. The single-piece primary PTFE probe body is resistant to leaks, and the removable secondary window enables users to service a fould sensor in minutes with no tools required.
This year’s winning projects for the second annual Top Water Quality Projects program come from all corners of the water treatment marketplace. These winners represent the most innovative and challenging projects submitted by readers to Water Quality Products (WQP) for recognition this year.
To be considered, all projects must have been in the planning or implementation phase in the past 18 months.
Over the years, the public has become more aware of drinking water quality issues. Urban development has placed increased stress on water resources, which in turn has increased the need for cost-effective methods to treat drinking water. This is true regardless of whether the installation is at a single point of use (POU) or at the point of entry (POE) for treating all water used in the home.
Choosing the right treatment option for the water supply
More than ever, sustainable surface and groundwater supplies are essential to communities across North America and around the world. The strains of industry and agriculture on groundwater are noticeable as pressures on water supplies intensify and supply patterns change. The increase in agriculture over vulnerable aquifers, climate change and hydrocarbon production are impacting water quality. Unregulated use or uncontrolled flow of groundwater can cause water quality degradation and conflict between water users.
Small drinking water systems opt for POE UV treatment
UV Pure Technologies’ ultraviolet water purification systems are leaders in effectiveness and advanced technology. Patented Crossfire technology is self-cleaning, fail-safe and virtually maintenance free. Hallett systems are NSF 55 Class-A certified; Upstream systems meet NSF 55A standards at UVT levels as low as 50%. All offer remote monitoring.
Safe drinking water is a privilege in North America. Though essential to good health, it is often taken for granted. It is delivered to our homes or offices for our enjoyment with little thought given to where it originated or how it got there. We expect water to come forth as required. We expect water to both look and taste good. We expect our health to be protected. It is only in times of crises that our awareness is devoted to this invaluable resource.
The advantages of combining chemical and physical processes
Trial and error methods are often used when developing products. Thomas Edison, with 1,093 patents, more than any other inventor, took many products and ideas and made them better. He would merely take a very good product, such as the light bulb, and make it commercially available. The light bulb had already been invented and used in labs, but Edison took the idea and developed it into a cost-effective product that could be sold commercially.
A few savvy tweaks greatly impact product development
