Paterson Iron Remover (Air Injected system) Advanced Iron Removal System
How Does the Paterson Iron Remover work?
The Paterson Iron Remover is a complete system for iron removal that is intended for use on private wells that contain levels of iron in excess of .3ppm to as high as 15ppm. The first operation is the injection of air into the water line by the Micronizer valve, a unique valve with a built-in, adjustable venturi. The injected air then oxidizes the soluble iron in the raw water after an appropriate contact time in the contact tank plumbed inline. The fine particles of oxidized iron are then filtered out of the water in the filter tank by a bed of specially formulated media. This media is periodically backwashed to waste by the automatic filter valve that the Paterson system is equipped with. This backwashing process rinses the iron that has been collected in the bed to your drain line.
These systems are fairly easy to install and require little to no maintenance.
System comes complete with:
- Pentair Logic series 263 automatic control valve on filter tank
- Fibreglass Contact tank which matches the system size
- Quick connect AVC (air vent control)
- Micronizer (air injection valve)
- Complete installation manual and warranty
The system requires the water to be within 6.5 to 10.0pH and have a minimum 5.0GPM for backwash rate.
Calculate the System Pump Capacity/Backflow Rate
1. Using a stopwatch or the second hand of your wristwatch, record the time that it takes for the pump to go through a complete pumping cycle – that is the time from when the pump starts at the low pressure setting (usually 20 or 30 psi) to when it shuts off at the high pressure setting (usually 40 or 50 psi).
2. Using a bucket or container, open a tap and collect the water until the tank pressure falls to the low pressure setting and the pump starts. By dividing the number of gallons collected by the time measured in (1) above, the capacity of the pump to deliver water to the pressure tank is obtained. A MINIMUM OF 5 GPM (gallons per minute) IS REQUIRED FOR THE PATERSON IRON REMOVER TO FUNCTION PROPERLY AND DRAW ENOUGH AIR THROUGH THE MICRONIZER VALVE. This usually requires a minimum of a ½ HP jet pump or a 1/3 HP submersible pump. To maximize flow rates on pumps at the low end of the necessary capacity, use a 20-40 psi pressure switch.
To ensure an adequate flow for backwashing the filter media, please ensure the following: 10” tank, 5GPM; 12” tank, 7 GPM; 13” tank, 10GPM. If inadequate backwash flow rates are used, the filter media will not be flushed properly and will eventually become plugged with iron and fail.
3. The pumping cycle should be at least 20 seconds. In some cases, the existing pressure tank may need to be replaced if it has too little capacity to allow this.
DRAW-DOWN _______÷ CYCLE TIME ______________x 60
= PUMPING RATE ______________
EXAMPLE: DRAW-DOWN is 6 gals; CYCLE TIME is 53 secs; then, PUMPING CAPACITY equals:
6 gals ÷ 53 secs x 60 = 6.8 gpm
This sytem is not recommended for Manganese removal but will reduce if not remove most levels of Hydrogen Sulfide.
