How can you assure adequate water quality to keep your drip system functioningat an optimal level? Start by choosing the right filtration for your particular conditions.To a degree, filtration is as much art as science. But there are several quantifiableparameters that can help you determine the right size filter for your needs. Theseinclude:1. Minimum and Maximum Operating Flow. This is the most critical factor when

sizing a filter. Do not confuse flow rate with line size; they often are notcompatible. For example, a two-inch filter that accommodates a 100 GPM (gallonper minute) flow rate will not work for a system with a 150 GPM flow rate; inthat case you would need to go up to the next larger size, or a three-inch filter.

2. Water Source. This determines what kind of debris you are you trying to trap.Generally speaking, well water contains inorganic debris such as sand, whilepond or surface water contains largely organic matter such as algae and leaves.Inorganic matter requires a smaller screen to trap the sand and sediment thatwould pass through a larger screen.

3. Minimum and Maximum Operating Pressure. Accurate pressure readings areimportant for two reasons: 1) each filter type has a maximum rated pressure ofoperation; and 2) if your system calls for an automatic, self-cleaning filter,minimum operating pressure must be maintained when the filter’s flushingmechanism is engaged.

4. Size of Downstream Orifice to be Protected. Generally speaking, a filter isnecessary to keep debris from clogging downstream sprinklers or other emissiondevices. The size of those orifices will determine the pore (i.e. micron) size ofyour filter element. As a rule of thumb, the proper filter porosity should maintaina ratio of 1:5 for drip irrigation and 1:3 for sprinklers. More specifically: drip80-100 micron (200-150 mesh); micro sprinklers (jets) 150-200 micron (100-80 mesh); impact sprinklers and rotors 200-400 micron (40-80 mesh).

5. Budget: This parameter is complex. One should take into account not only theinitial cost of a filter but also the cost of maintaining a system without filtration.Automatic, self-cleaning filters are more expensive than manual filters, but whenlabor costs are factored in may be less expensive in the long run.

Automatic Water Filter

rip irrigation systems take the worry outof watering – unless emitters become

clogged with dirt and other contaminants that spewforth from the water source. Then watering becomesa labor-intensive process requiring constant monitoringand frequent cleaning, often canceling out the timeand money saved by the drip system itself.

Water quality is a key factor in the success ofdrip irrigation systems. The purity of the water canbe affected by many factors including seasonalchanges, pipeline conditions and flow velocity, rateof turnover of ponds, and changing sources of water,among others.

The Tekleen Automatic Filter is self cleaning and operates on line pressurealone, eliminating the need for an external power source. The filter offersthe following benefits:• Fully automatic and self-cleaning• Environmentally friendly• Cost-effective• Maintenance free• Compact design
