Blog circa New Filtration System Cuts Wastewater Risks for Screen Printing Industry

Screen printing professionals face an often-overlooked environmental challenge: the wastewater generated during the cleaning process. While the industry focuses on vibrant colors and precise designs, the hidden threat of microscopic solid waste particles silently contaminates drainage systems and undermines environmental commitments.

The Sgreen® filtration system introduces an innovative six-stage purification process designed to transform contaminated washout water into an environmentally safe resource:

1. Primary Defense: Disposable mesh screens capture larger particles like emulsion chunks and undissolved ink clusters.
2. Triple-Layer Refinement: Reusable mesh filters (86, 156, and 200 mesh counts) progressively remove smaller ink particles and contaminants.
3. Precision Filtration: A 70-micron filter captures subvisible particles that bypass earlier stages.
4. Ultimate Purification: The 20-micron final filter achieves water clarity surpassing visual detection limits.

This industrial-grade system offers multiple benefits for printing facilities:

• Prevents drainage system contamination and pipe blockages
• Reduces maintenance downtime by up to 40% in high-volume shops
• Complements existing water reclamation systems when used as pre-filtration
• Constructed with corrosion-resistant stainless steel for durability

To maintain peak efficiency, operators should:

• Conduct weekly inspections of filter media
• Implement ink management protocols to reduce solid waste at source
• Coordinate with water reclamation systems for maximum resource recovery

The compact system (31.73" W × 20.73" D × 18.92" H) accommodates standard workstations and includes replaceable filter components:

• 16 × 20" OD mesh screens (86, 156, 200 count)
• 70-micron and 20-micron cartridge filters
• Supplementary filtration pads

This technological advancement represents a significant step toward sustainable printing practices, addressing both environmental concerns and operational efficiency in industrial screen printing environments.
