F110HDZ
ARKA
The F110HDZ is a 4-inch automatic disc filter designed for farm irrigation systems and commercial water treatment applications requiring continuous filtration with self-cleaning capability. This unit uses stacked disc elements to remove suspended particles from water, with an automatic backwash function that cleans the filter elements without interrupting the water supply to downstream systems.
The F110HDZ filter employs a stack of grooved disc elements that capture particles as water passes through the narrow channels formed between adjacent discs. During normal filtration, water flows from the outside of the disc stack inward, with trapped particles accumulating on the outer surface. When the pressure differential across the filter reaches a predetermined threshold, the automatic backwash cycle initiates, reversing the flow through a portion of the disc stack to flush accumulated debris out of the system.
The F110HDZ features a modular design that allows multiple filter units to be connected in parallel to accommodate higher flow rates or expanded system capacity. Each unit maintains consistent filtration performance, and the modular configuration enables system designers to scale filtration capacity according to project requirements. The plastic body construction contributes to corrosion resistance and reduced overall system weight.
The automatic backwash function is driven by hydraulic pressure and controlled by an integrated valve system that directs water flow through the filter in reverse direction during cleaning cycles. Unlike manual filters that require operator intervention, the automatic system initiates backwashing based on pressure differential or timed intervals, reducing the need for on-site personnel and supporting unattended operation. The backwash process cleans one section of the disc stack at a time while other sections continue filtering, maintaining uninterrupted water supply.
The F110HDZ disc filter supports different filtration grades by using disc elements with varying groove depths and spacing. This allows operators to select the appropriate level of filtration based on source water quality and downstream equipment requirements. Common filtration grades address particle sizes ranging from coarse sediment removal to fine filtration for drip irrigation systems that require protection against emitter clogging.

The head loss characteristics of the F110HDZ disc filter vary with flow rate and filtration grade. The unit is designed to maintain low pressure drop across the filter element during normal operation, with head loss increasing gradually as particles accumulate on the disc surfaces. The 130 micron disc configuration shows specific head loss values at different flow rates, with the relationship following a predictable curve that allows system designers to calculate pressure requirements for specific installations.
For the 4-inch F110HDZ model, head loss values remain within acceptable ranges for typical agricultural irrigation operating pressures. The head loss curve serves as a reference for system design, enabling engineers to properly size pumps and pipeline components to compensate for filter pressure drop under expected flow conditions. Actual head loss in field installations may vary based on water quality characteristics and disc filtration grade selected.
In farm irrigation systems, the F110HDZ automatic disc filter protects downstream equipment including drip emitters, micro-sprinklers, and spray nozzles from clogging caused by suspended particles. The automatic backwash feature reduces maintenance labor for large irrigation systems where manual filter cleaning would require significant time and personnel. Farms and agricultural operations benefit from consistent filtration performance and reduced downtime associated with filter maintenance.
Industrial facilities use automatic disc filters for process water treatment, cooling water systems, and water recycling applications. The modular design allows configuration of filtration systems sized to match specific industrial flow requirements. The automatic self-cleaning function supports continuous operation in industrial settings where process interruption would affect production schedules and operational efficiency.
Greenhouse and nursery operations rely on consistent water quality for healthy plant growth. The F110HDZ disc filter removes particulate matter that could clog drip irrigation lines or affect nutrient delivery systems. The automatic backwash capability reduces maintenance demands on facility staff, allowing them to focus on crop management rather than filter maintenance.
The F110HDZ automatic disc filter installs in the main water supply line upstream of the irrigation or distribution system. Proper installation requires sufficient space around the unit for maintenance access and backwash discharge piping. The unit should be positioned with inlet and outlet connections aligned to minimize pipeline stress, and pressure gauges should be installed on both sides to monitor differential pressure across the filter element.
Backwash cycles can be configured to initiate based on pressure differential across the filter or according to a timed schedule. Pressure differential activation triggers backwashing when the accumulated debris causes a specific pressure drop, providing an efficient cleaning schedule that responds to actual filter conditions. Timed activation follows a preset schedule, which may be appropriate for applications with consistent water quality and predictable particle loading.
The F110HDZ disc filter supports multiple filtration grades determined by the disc element specifications. Different disc configurations provide varying levels of particle removal, from coarse filtration for sediment removal to finer grades suitable for drip irrigation protection. Operators select the appropriate disc grade based on source water quality and the requirements of downstream equipment.
The automatic backwash function uses hydraulic pressure to reverse water flow through a portion of the disc stack, flushing accumulated particles out through the drain outlet. The backwash valve directs flow through the filter in reverse direction, causing the disc stack to slightly separate and release trapped particles. During this process, other sections of the filter continue normal filtration, ensuring uninterrupted water supply to the system.
Yes, the modular design of the F110HDZ allows multiple units to be installed in parallel to handle higher flow rates or provide additional filtration capacity. Each unit operates independently with its own backwash cycle, and the system can be expanded by adding more filter units as flow requirements increase. This scalability makes the filter suitable for projects ranging from small installations to large commercial irrigation systems.
The automatic backwash function requires sufficient inlet pressure to drive the reverse flow through the disc stack and effectively remove accumulated particles. Systems with low inlet pressure may require pressure boosting or alternative backwash configurations to ensure effective cleaning. Operators should verify that system pressure meets the minimum requirements for backwash operation before installation to ensure proper filter performance.
