Turning Pre-Separated Liquids Into A Valuable Resource: How POLYLESS MFT Supports More Efficient Irrigation Management

Water management in agriculture is becoming increasingly demanding. Farmers and plant operators are expected to optimise the use of available resources, reduce waste, manage liquid streams more responsibly and, wherever possible, recover value from materials that were once considered difficult to handle. In this context, the quality of liquid treatment upstream of reuse is no longer a secondary issue—it is a practical factor that directly influences storage, pumping, distribution and the overall efficiency of irrigation systems.

This is precisely where POLYLESS MFT, the micro-filter developed by SAVECO, delivers measurable value. Designed for the treatment of pre-separated liquids, the unit performs high-efficiency micro-filtration through a system in which a motor-driven internal tool generates the force required for separation, while a screen retains the solid phase and allows the filtered liquid fraction to be discharged separately. According to the official product brochure, the machine can operate with screen spacing as fine as 25 microns (0.025 mm), ensuring exceptionally high separation efficiency within a compact footprint.

For agricultural operations, this capability is more significant than it may initially appear. Irrigation systems depend on continuity, reliability and consistent liquid quality. When liquids still contain fine suspended solids, fibrous material or residual particles, the result is often operational inefficiency: pumps work harder, downstream equipment experiences greater wear, and distribution systems become more vulnerable to clogging, blockages or reduced long-term performance.

By improving the quality of the liquid fraction after primary separation, micro-filtration creates better conditions for reuse and more efficient handling. Cleaner liquids are easier to store, transfer and distribute, while reducing the risk of system interruptions and maintenance-related downtime.

This perspective is further supported by recent academic research. A 2025 study conducted by the University of Ferrara on nutrient recovery from digestates examined different livestock and organic waste matrices, including a microfiltered swine digestate processed using a SAVECO 40 MFT unit. One of the key findings was that pre-treatment steps such as clarification and micro-filtration can increase ammonium removal efficiency by 15–25%, significantly improving the suitability of the liquid phase for subsequent recovery and reuse.

In practical agricultural terms, this confirms the role of micro-filtration not only as a separation step, but as an enabling technology for more efficient liquid management and more reliable integration into circular irrigation and fertigation strategies. It supports a broader shift in agriculture—from waste treatment towards resource optimisation.

POLYLESS MFT fits naturally into this approach. Farms and agricultural facilities increasingly require solutions that support circular thinking: reducing the solid content in the liquid phase, simplifying subsequent storage and transfer, and making treated liquids easier to manage in applications linked to irrigation, fertigation or water recirculation strategies.

The product brochure itself presents the equipment as part of a ‘high-tech solid-liquid separation’ approach for the circular economy. This is particularly relevant in agriculture, where any improvement in reuse potential can translate into both operational and environmental benefits.

One of the key strengths of POLYLESS MFT is that it does not rely on complexity to deliver performance. SAVECO highlights a stainless-steel structure, an IE3 premium efficiency electric motor, cemented carbide mechanical seals, a dedicated control panel and a progressive cavity pump among the main features and accessories. At the same time, the focus remains firmly on user benefits: very low maintenance requirements, high throughput rates combined with low energy consumption, and affordable spare parts.

Serviceability has also been carefully considered. The top hatch is designed to provide quick and easy access to the main machine components, reducing inspection and maintenance times and supporting greater operational continuity.

This balance between performance and simplicity is particularly important in irrigation-related agricultural environments, where operators are not looking for an isolated piece of machinery, but for a dependable process component that integrates seamlessly into daily operations without creating unnecessary servicing burdens.

Equipment used in these contexts must be robust, straightforward and economical to run. A solution that improves liquid quality but requires constant intervention may struggle to deliver real value in the field. By contrast, a solution that enhances liquid management while remaining accessible in terms of maintenance and operation is far more aligned with the practical needs of modern agricultural users.

The available model range further supports this flexibility. According to the brochure, POLYLESS MFT is available in two versions—MFT-260 and MFT-500—both equipped with 7.5 kW drive power. The units are designed to handle pre-separated liquid streams with inlet dry matter content between 1% and 5%, delivering throughput capacities of up to 10 m³/h and 20 m³/h respectively under standard operating conditions.

SAVECO identifies livestock farming, pig farming and biogas plants among the main applications, confirming the equipment’s relevance wherever organic liquid streams require refinement after an earlier separation stage.

From an irrigation perspective, this positioning is particularly significant. Agricultural operators managing digestate-derived liquids, manure-related streams or other process liquids often require an intermediate treatment step capable of stabilising the liquid fraction before transfer, reuse or further process integration.

In these cases, micro-filtration is not simply about removing particles. It is about enabling more manageable liquids, supporting more stable downstream performance and contributing to better overall process control. When irrigation systems or reuse strategies depend on cleaner liquid fractions, a micro-filter becomes a strategic asset rather than just an accessory.

Within the wider WAMGROUP range, this approach reflects a long-standing focus on practical, market-oriented solutions for wastewater treatment and process efficiency. WAMGROUP is recognised globally for technologies supporting solids-liquid separation, bulk material handling and wastewater treatment, with a strong emphasis on user-friendly, industrial-quality equipment solutions developed around real operational needs.

This background strengthens the positioning of SAVECO equipment such as POLYLESS MFT—not as generic machinery, but as purpose-built technology designed to deliver measurable improvements in plant performance, sustainability and resource efficiency.

In agriculture today, efficient irrigation is no longer simply about delivering water. It is about delivering a liquid stream that is suitable for the system it enters, while supporting broader goals of sustainability, resource recovery and operational continuity.

By helping transform pre-separated liquids into a better-managed and more valuable resource, POLYLESS MFT offers a concrete and practical answer to this challenge.
