Membrane micro-filtration unit EF/EFC series

Compact Skidskidfor wastewater treatment

Overview
Memtek EFC-Series microfiltration systems are engineered for wastewater treatment and process filtration. They use proprietary crossflow tubular membranes to remove precipitated contaminants and deliver filtrate suitable for discharge, reuse in non-critical rinses, or as feed to reverse osmosis (RO). The modular design supports standalone units, combined trains or integration with existing equipment. When used as RO feed, typical plant water recovery is 75–90%. Standard E-Series units handle flows up to 400 gpm; larger capacities are available through custom design. These systems provide continuous solid/liquid separation and simplified operation.

EF Advanced Membrane Filtration Systems
The basic EF skid-mounted package is compact and includes core process and cleaning components. Key elements include:

• Membrane modules (proprietary crossflow tubular membranes)
• Recirculation pump
• In-place cleaning loop
• Backpulse mechanism
• Instrumentation and controls

EFC Advanced Membrane Filtration Systems
The EFC configuration expands the EF skid package by adding recirculation and slurry handling features. The EFC system includes:

• Recirculation tank with level controls
• Anti-swirl baffles
• Slurry transfer pump

RX and RXP Reaction Systems
RX/RXP reaction systems are process-ready tanks designed to support chemical reaction and mixing upstream of membrane separation. Typical features include:

• Corrosion-resistant tanks
• Heavy-duty mixers
• Metering pumps
• Chemical reaction monitors and controllers
• Level controls and alarms
• Inlet, overflow and drain ports
• Control panel
• Access platform and covers

Materials of Construction
Systems are built for chemical and abrasion resistance. Key construction details include:

• Membranes: fluorocarbon tubular membranes — non-plugging, abrasion- and chlorine-resistant
• Process tanks: fiberglass-reinforced epoxy (FRP) or high-density polyethylene (HDPE)
• Wetted components: PVC, polypropylene, nylon, stainless steel or other corrosion-resistant materials

Technical specifications

• Standard E-Series flow capacity: up to 400 gpm (standard units); custom designs available for higher flows
• Filtrate quality: suitable for discharge, reuse in non-critical rinses, or as RO feed
• RO recovery when used as RO feed: typical plant recycle 75–90%
• Separation mode: continuous solid/liquid separation via crossflow tubular membranes
• EF system components: membrane modules, recirculation pump, cleaning loop, backpulse, instrumentation & controls
• EFC additions: recirculation tank, level control, anti-swirl baffles, slurry transfer pump
• Construction materials: fluorocarbon membranes; tanks in FRP epoxy or HDPE; wetted parts in PVC, polypropylene, nylon, stainless steel
