| debris. Iron
in the water can cause the lines to clog and the automatic watering
system to fail. |
| This is a common
problem whenever high iron content water is used to water crops.

air, the iron particles released block the tiny end points causing
the sprinkling system to fail. If used to spray plants, the iron
particles released stain the plants. |

| For this
system, then, a necessary component is a meted feeder pump
that adds food grade phosphate to the water, which defeats
iron contamination. CWS is responsible for choosing the
right phosphate in the right solution mixture for the job.
At Johnson Nurseries both the iron
filter and the softener
are scaled to size to meet the necessary requirements -
in this case, 2000 gallons per day. |
