The DEP___DLP SERIES is a centralized self-cleaning filtration system engineered for the continuous treatment of irrigation water, nutrient solutions, fertilizers, livestock water, wastewater, and industrial process liquids. Designed for demanding fertigation, agricultural, livestock, and water-treatment applications, the system combines advanced disc filtration technology, automatic backflushing, and intelligent hydraulic control to provide uninterrupted filtration with minimal maintenance and operating costs.

Unlike conventional filtration systems that require shutdowns for manual cleaning or cartridge replacement, the DEP___DLP SERIES performs automatic self-cleaning cycles while remaining fully operational. During backflushing, only one filter module is cleaned at a time, while the remaining filters continue operating without interrupting water or liquid supply to the process.

Advanced Disc Filtration Technology

The DEP___DLP SERIES uses a high-efficiency disc filtration system designed to remove suspended solids, organic matter, sand, sediment, and other contaminants from water and liquid solutions.

Each filter consists of a stack of specially designed discs that provide both:

• Surface filtration

• In-depth filtration

As the untreated liquid flows through the disc channels, contaminants are retained within the filtration media, while the filtered liquid exits through the outlet manifold.

An integrated Helix System generates a controlled helical flow inside the filter housing. The resulting centrifugal effect keeps larger particles away from the filtration surface, reducing clogging, extending filtration cycles, and minimizing the frequency of automatic cleaning operations.

Continuous Self-Cleaning Operation

The system operates through two fully automated phases.

Filtration Phase

• Untreated water or process liquid enters the inlet manifold.

• The flow is evenly distributed across all filter modules.

• Suspended solids and contaminants are retained inside the disc channels.

• Filtered liquid is supplied continuously to the irrigation network, dosing system, livestock facility, or downstream treatment process.

Automatic Backflushing Phase

When cleaning is required, the control system isolates one filter module while the remaining units continue normal filtration.

During backflushing:

• Hydraulic valves reverse the flow direction.

• Pressurized water enters the filter tangentially.

• The disc stack expands and vibrates.

• Retained particles are removed from the filtration surfaces.

• Contaminants are discharged through the drainage manifold.

The cleaning cycle is completed within seconds, without interrupting the supply of filtered liquid.

Intelligent Control System

The DEP200DLP SERIES automatically manages filtration and cleaning cycles through multiple activation methods:

• Differential-pressure monitoring

• Time-based cleaning cycles

• Manual operator activation

• External PLC or automation signals

• Remote control and monitoring options

This flexible architecture allows easy integration with fertigation controllers, water-treatment systems, centralized dosing units, and Industry 4.0 process-control platforms.
