The Fleck 2900 2” control on the Metered 2” Nitrate Twin Alternating System and the Fleck 3900 control on the Metered 3” Nitrate Twin Alternating Systems are used where 24 hours protection is needed such as schools, hospitals and other such establishments and the small to larger municipalites depending on the flow rate you are needing. The Twin Tank Alternating System insures continuous nitrate reduction with one tank always in service while the other is in regeneration or in standby. The systems are metered so that regeneration is always on a pre-set basis for precise and economical treatment of your water.

 


ABOUT KRUDICO’S COMMERCIAL/MUNICIPAL NITRATE REDUCTION SYSTEMS

Krudico's Nitrate Reduction systems are available in many different tank and control valve sizes to handle both your flow rate requirements and the nitrate con-tent of your water. All systems are alternating in design in that one or more tanks are on line while one tank is in regeneration/standby. All control valves are meter initiated, the gallonage between regenerations is pre-set to prevent overruns and minimize salt consumption.

The 1 1/2" systems are twin alternating only while the larger 2" and 3" models may have two, three or more tanks in parallel for higher flow rates and capacities, dependent on the individual needs of the water supply.

All models are equipped with internal "no hard water" bypasses so that raw water containing nitrates cannot enter the system during regeneration.

Tanks made of non-corrosive fiberglass which eliminates the potential leaks from pitting, etching or electrolysis, problems common with metal tanks.

Krudico, Inc. has been a forerunner in nitrate reduction using nitrate selective resins since they became available in the mid 1980's. Prior to the manufacture of selective resins, nitrates were reduced by running water through standard anion resins manufactured by several USA and foreign companies.

The standard anion resins, while able to reduce nitrates, had one large liability. If the water to be treated contained sulfates, the sulfate ions were held onto the resin media stronger than the nitrate ions. Therefore, if the equipment malfunctioned, ran low on salt for regeneration or the water chemistry changed, nitrates could be "dumped" in the water supply at much higher levels than contained in the influent raw water. This is caused by the stronger held sulfates pushing the nitrates off the resin during the normal service run of the equipment.

Nitrate Selective resin has a higher affinity for nitrates than sulfates, therefore preventing the dumping of high amounts of nitrates even if the resin is run past it's capacity. At that point, the effluent nitrates will be no worse than what is contained in the influent raw water supply.

Interior Distribution System made of non-corrosive PVC with .010 slotting to prevent resin loss.

 
2" & 3" N03 SYSTEM CONTROL VALVES

The Krudico 2" models have a separate control valve mounted on each tank. These systems can be installed with two or more tanks in parallel, dependent on the flow rates required and the Nitrate removal needs. There is one common 2" or 3" reset meter on the effluent or outlet line of the total system that measures the water flow. When a preset amount of water has passed through, the meter signals for one tank to go into regeneration. After regeneration, this tank will stay on standby until the reset meter calls for another tank to go into regeneration. At this time, the standby tank will come back on line and allow the second tank to go into regeneration/standby. This sequence is continuous in either two tank or multiple tank installations.

If the meter calls for a second tank to regenerate before the first tank has finished its cycle, the meter will hold off the signal until the first tank is ready to come back on line. This is to insure proper flow rates are available at all times.

All of the control valves are equipped with a "no raw water" bypass to prevent untreated water from entering the system during the regeneration cycles.
