Purification & Filtration Systems
Protect irrigation infrastructure from source to emitter
Farmnet designs and supplies complete water filtration systems for agricultural irrigation — sand and gravel filters, disc filters, screen filters, and centrifugal separators. Matched to source water quality and flow requirements, with automatic backwash management and integration into the Farmnet Platform.
our core strengths
Proven at Scale, Built for Performance
Farmnet manages the variables that determine crop consistency and operational efficiency. Systems are deployed across greenhouse, open-field, and indoor production environments, providing real-time control of temperature, humidity, CO₂, water delivery, and nutrient dosing.
Operating at national scale within the world's largest agricultural economy. Farmnet systems support dense networks of greenhouse and open-field operations across the highest-intensity production regions.
End-to-end production capability. Controllers, fertigation units, and system components are designed, produced, and validated within Farmnet's dedicated industrial facilities.
More than a decade of continuous development in agricultural control systems, refined through multiple technology generations and operational requirements.
Multidisciplinary engineering organisation focused on agricultural automation, control architecture, hardware design, and software systems.
Systems operating across diverse climates and production models—from arid environments to advanced controlled-environment agriculture.
Thousands of systems in continuous 24/7 operation, generating long-term performance data that informs system reliability and design.

Key Features
Source-matched filtration
Filter type, media, and filtration degree are specified based on actual source water analysis — not generic sizing.
Automatic backwash management
Differential pressure sensors trigger backwash cycles automatically when filter media reaches loading threshold — no manual intervention.
Emitter and equipment protection
Removes suspended solids, algae, and organic matter that cause drip emitter clogging, valve seat wear, and fertigation equipment damage.
Multi-stage filtration options
Coarse pre-filtration (centrifugal or sand) combined with fine filtration (disc or screen) for demanding source water conditions.
