How to Choose a Water Filtration System for Agricultural Use In the U.S.?

Selecting the right agricultural water filtration system depends on four primary factors:​​

  1. Water Source

  2. Water Quality

  3. Irrigation Method

  4. Flow Rate Requirements

Step 1: Identify Your Water Source

Common Contaminants

Typical Filtration Solution

  1. Well Water »

  2. Canal Water »

  3. Reservoirs/Ponds »

  4. Reclaimed Water »

  5. Surface Water »

  1. Sand, silt, iron, & manganese »

  2. Algae, organic matter & sediment »

  3. Algae, weeds, & biological growth »

  4. Organics & suspended solids »

  5. Sediment, debris & algae »

  1. Sand separators, screen filters & sand media filters

  2. Sand media filters + screen/disc filters

  3. Sand media filters & wedge wire screen filters

  4. Multi-media filtration with automatic backwash

  5. Media filters & secondary polishing filters

Step 2: Test Your Water

A water analysis should include:

  1. Total Suspended Solids (TSS)

  2. Turbidity (NTU)

  3. Particle size distribution

  4. Iron & manganese

  5. pH

  6. Biological content (algae & organics)

The particle size distribution is especially important because it determines the filtration micron rating required to protect irrigation equipment.

Step 3: Determine Irrigation Type
Drip Irrigation

Requires the highest level of filtration.

  • Typical filtration: 120 – 200 mesh

  • Approximate particle removal: 130 – 75 microns

  • Common systems: Sand media filters, disc filters & screen filters

Micro-Sprinklers

  • Typical filtration: 80 – 120 mesh

  • Often uses automatic screen or disc filtration

Center Pivot Irrigation

  • Typical filtration: 40 – 80 mesh

  • Often utilizes screen filters or sand separators

Flood Irrigation

  • Minimal filtration requirements

  • Focuses primarily on debris removal

Step 4: Calculate Required Flow Rate

Filter sizing is based on system flow. Typical agricultural systems:

  1. Flow Rate: Under 100 GPM = Single automatic screen filter 

  2. 100 - 500 GPM = Sand media or disc filter system

  3. 500 - 2,000 GPM = Multi-vessel media filtration

  4. 2,000+ GPM = Engineered filtration systems with multiple vessels

Undersizing filters can cause excessive pressure loss and frequent backwashing.
