Scepter® Micro/Ultrafiltration System

Scepter® Micro/Ultrafiltration System

Ecodyne’s Scepter Microfiltration/Ultrafiltration systems represent the ultimate filtration solution for demanding applications with difficult process conditions or streams with high solids or viscosity. The Scepter® UF module is a cross-flow stainless steel membrane, constructed of porous stainless steel tubes which are coated with a unique titanium dioxide membrane. The result is a MF/UF system which performs regardless of the extreme pressures, pH and temperature.

Features & Benefits

  • Robust microfiltration/ultrafiltration: Constructed of stainless steel and titanium, our 0.1 or 0.02 micron filter prevents particle penetration and plugging and operates in the most challenging applications.
  • Leak Free – Gasket-free, all welded construction gives outstanding mechanical stability
  • High Solids Content – Large diameter tubes handle up to 50% suspended solids by volume.
  • Full pH Range – Operates the entire pH range of 0-14
  • High temperature compatible—able to operate continuously up to 600°F / 315 °C.
  • Steam Sanitizable – Can easily be steam sanitized with no negative effects.
  • High pressure capability—up to 1,000 psig / 70 bar.
  • Chemical Compatibility – Easily withstand chemical sanitization, aggressive caustic and acid cleaning agents
  • Flexible Configuration – Can operate in either horizontal or vertical orientation.

How it works

  1. Continuous Operation – The Scepter feed pump pressurizes the feed to the required pressure (determined through pilot testing) and injects it into the circulation loop that provides circulation cross-flow in the Scepter filtration tubes. Filtrate passes through the filtration layer on the inside of the Scepter tubes and into the shell side of the module. Flow of filtrate is controlled through a flow control valve on the shell side of the module. The tube side of the module concentrates solids to the target level and is purged through a flow control valve to downstream dewatering or disposal.
  2. Batch Operation – In batch mode, the concentrate returns to the feed tank, where it mixes with the incoming feed to increase the feed tank concentration. When critical feed tank concentration is achieved, the tank contents are directed to recovery or disposal.
