NO-DES Unit Applications

​

The primary use for the patented NO-DES flushing system is flushing potable water distribution mains. NO-DES flushing alleviates wasting large amounts of water associated with conventional flushing methods. The energy and money required to pump, pressurize, and treat wasted water is saved.

​

Relative to the use of chloramines as a disinfectant and the issues associated with it, such as the breakdown/loss of residual, elevated free ammonia levels, nitrification and the resulting bio-film growth.

​

We’ve developed our NO-DES flushing process in a way that enables the NO-DES flushing unit operator to combat these issues by both flushing and boosting chloramine levels at the same time. This is achieved by precisely adding the appropriate amounts of liquid chlorine during the flushing cycle, which then combines with the measured free ammonia in the water to reform chloramines.

​

Many utilities flush solely to remove water with high free ammonia levels, in an effort to prevent nitrification from occurring. The NO-DES unit can be used solely for that purpose as well, reducing the free ammonia levels and reforming chloramine levels to the desired concentration in large sections of main (much larger than a flushing cycle).

​

The significance of using our NO-DES unit is that it can target specific areas in the water distribution system where and when chloramine or chlorine boosting is needed – which is a feature unique to our product. Used in this manner, it functions as a portable chloramine or chlorine boosting system. Flushing can also be performed at the same time, which will significantly slow down the deterioration of the systems disinfectant residual in the future.

​

By incorporating the 1.0 micron absolute filter cartridges water quality is improved and health risks are eliminated by removing particulates, bio films, etc; and safety is ensured with the ability of adding an optional disinfectant.  National Pollution Discharge Elimination System (NPDES) regulations and associated issues are reduced significantly or eliminated.

​

Operating for less than the cost of current conventional flushing methods, the NO-DES system can be utilized 24/7, 365 days a year, without negatively affecting the water distribution system and customers. The NO-DES unit controls the flushing flow rates preventing any damage or water hammer to your water distribution system.

 

Leading by example in water conservation, the NO-DES flushing system eliminates the need to open fire hydrants and waste large volumes of water, especially for those utilities that have voluntary or mandatory rationing requirements in place.

 

Secondary Applications

 

The NO-DES unit can be used to conserve water when large water meters are tested in the field. Instead of discharging water into the street, a 2-1/2″ hose is attached to the top of the meter test-tap pipe with the water flowing through the NO-DES unit and back into the distribution system via a hydrant. Not only does the NO-DES unit filter and disinfect the water that is being circulated through it and into the distribution system, the NO-DES unit’s flow meter can be used to confirm the accuracy of the meters being tested.

​

Flushing after water main repairs is a must to remove any contaminations incurred during the repairs and from the loss of pressure. The NO-DES unit eliminates the need to flush to the street after a water main repair and also safely adds disinfectant without wasting additional water. By using the NO-DES system, not only is the water clean and safe, it is ready for Bac-T sampling.

​

The NO-DES unit is designed to be used as a standard booster or transfer pumping unit. Benefits of the NO-DES unit include the ability to filter the water being transferred as well as chlorination, which are not available with traditional booster systems.

​

The NO-DES unit can perform tank draining. Simply connect one end of the transfer hose to the drain outlet of the tank and the other to the inlet of the NO-DES unit. A separate transfer hose is then connected from the discharge of the NO-DES unit to a hydrant. The NO-DES unit will filter the water that is being transferred into the distribution system and can be optionally chlorinated.
