Advanced Mini Screens
Compact screening technology delivering fine solids removal in space-constrained installations with minimal footprint
Overview
What is Advanced Mini Screens?
Advanced mini screens provide effective fine solids removal in applications where space limitations prevent installation of conventional screening equipment. These compact units incorporate sophisticated screening mechanisms into minimal footprints, making them ideal for upgrades, package plants, decentralized systems, and retrofit installations.
Despite their small size, mini screens deliver performance comparable to larger equipment through innovative designs featuring optimized screen geometries, efficient cleaning mechanisms, and high-quality screen media. Automatic operation ensures continuous performance without manual intervention, while stainless steel construction ensures durability in harsh wastewater environments.
Spans Envirotech's advanced mini screen solutions include static wedge wire screens, self-cleaning rotating screens, and perforated plate screens engineered for maximum efficiency in minimal space. Our compact designs integrate seamlessly into existing facilities, providing reliable solids removal without requiring extensive civil modifications.
Process
Mini Screen Operation
Flow Entry
Wastewater enters the compact screen chamber through an inlet designed to distribute flow evenly across the screen surface, preventing overloading of specific areas.
Solids Capture
Fine screen openings (0.5-3mm) retain suspended solids, debris, and fibrous materials while allowing water to pass through. Wedge wire or perforated plate construction prevents blinding.
Automatic Cleaning
Rotating brushes, spray nozzles, or screen movement continuously clean captured solids from screen surfaces, maintaining high screening efficiency throughout operation.
Screenings Removal
Removed solids are conveyed to collection containers or chutes by integrated mechanisms. Compact screenings handling minimizes installation space requirements.
Screened Water Discharge
Clean water flows through the screen to downstream processes. Low headloss design minimizes pumping requirements and energy consumption.
