Modular High-Capacity UV Disinfection System
Safe Water Solutions (Brown Deer, Wisconsin) is offering a new, modular, high capacity disinfection system that has demonstrated high inactivation rates when used over a wide range of microorganisms and viruses. The Model TH-IC
is said to incorporate significant advances in ultraviolet technology. It can be optimized by application for disinfection of industrial effluent, process water, drinking water, wastewater (primary, secondary, or tertiary effluent), combined sewer overflows, and stormwater discharges. The equipment is compact and well-suited for use by mobile forces and disaster relief teams.
The unit's disinfection chamber contains 18 60-in.-long ultraviolet lamps that run the length of the space. Each lamp is protected by a teflon-coated quartz sleeve. Temperature inside the sleeve is maintained within the optimum operating range. Reduced maintenance and minimal fouling are said to be made possible by these sleeves and by the TH-IC's unique turbulator flow pattern, which is established by three rows of segmented stator blades, each arranged in a helix and welded to the inner chamber wall. All contaminants in the water are brought repeatedly and positively on to the sleeves surrounding the 18 UV lamps. This ensures that multiple lethal doses are delivered. Vigorous turbulence in the chamber and the sharp-edged stator blades break down suspended solids, further enhancing disinfection efficiency.
A detector on the outer wall of the irradiation chamber measures the intensity of the 253.7 nm UV radiation it receives through the flowing water. Electronics within the control panel continuously monitor key components and the UV intensity at the specific germicidal wavelength. This data is used to compute and display actual intensity, lamp status, and safety circuit alarm.
Maximum flow rate for primary effluent is 660 gpm, and up to 1,400 gpm for clean water applications. The system can accommodate operating pressures up to 145 psig. Installations are sized according to flow rate and water quality, and multiple units can be manifolded to handle increased flows or variable water quality. The system is skid-mounted on a 316L stainless steel frame for ease of installation and placement. An enhanced cleaning arrangement is an option, as is remote monitoring.
