Maximize the effectiveness of existing treatment methods Ultraviolet disinfection systems pose a daunting problem to their manufacturers and users. Extremely effective at their job when working at full strength, their functionality is easily reduced by film buildup caused by water conditions, which can render treatment ineffective. The UV light bulb, which delivers the appropriate dose of light based on design specifications, is enclosed in a quartz crystal sleeve. Glass is not used, because glass does not transmit UV light very well. During the course of operation, the quartz crystal sleeve becomes warm, and scale and bio-film deposit on the sleeve. The deposits hinder the transmission of the UV light, and reduce the disinfection ability of the UV unit. To restore full functionality, it is necessary to remove the unit from operation, and clean the quartz sleeve with an acid solution. This results in unnecessary downtime and chemical handling. The use of a TWT chemical-free deposit control system will protect the UV quartz sleeve from this disruptive buildup, reducing downtime and maintenance costs. |

The Triangular Wave System should be installed before the upstream entrance to the UV unit. The system will treat the scale and biofilm-forming particles to prevent deposition, substantially increasing the periods between sleeve cleaning operations. Reverse osmosis membrane filtration systems are also very effective in what they do, but are known to frequently become clogged with scale and biological particles, and must be back-flushed on a periodic basis in order to maintain that effectiveness. The efficiency of the filtration units is monitored by measuring the amount of permeate (clean water) that passes through the unit in a given time. The brine (dirty water upstream of the filter) becomes more concentrated with scale ions and bacteria, viruses, and algae as the filtration unit works. Periodically, some of the brine will be bled off to reduce the brine concentration. Another common problem with RO units is the buildup of scale along the edges of the filter membrane. That scale can open channels and allow the filter to be short circuited. To maintain effectiveness, a Triangular Wave Deposit Control System should be installed upstream of the RO unit to treat the scale and biological particles. The particles will remain suspended in the brine, and membrane clogging will be greatly reduced. Furthermore, scale will not form around the edges of the membrane.
The Triangular Wave Deposit Control System is able to control bacterial contamination by removing the habitat the bacteria need to feed and propagate. Corrosion in water systems is commonly caused by either acid action or biological action. With higher concentration ratios allowed, the Total Dissolved Solids levels and pH levels rise. At higher pH's there is a smaller chance of corrosion according to Langlier's Scale. Scale will deposit when pressure, temperature, or pH change quickly. In the case of a spray nozzle, the pressure rapidly changes and scale collects at the nozzle opening. The Triangular Wave System treats the scale particles so that they are in crystal form. The scale particles stay suspended in the water and do not attach to the nozzle opening.
