Microfiltration, Ultrafiltration (UF) and Nanofiltration Membrane Systems

Newterra Microfiltration, Ultrafiltration and Nanofiltration Membrane Systems for total suspended solids (TSS) and oil removal from industrial wastewater and reverse osmosis (RO) pretreatment.  Newterra microfiltration, ultrafiltration and nanofiltration membrane water treatment solutions are engineered and built to maximize uptime and minimize process water maintenance requirements.

Ultrafiltration Systems can be used as pretreatment for our SeaMega Seawater Desalination Systems and both Ultrafiltration and Nanofiltration Systems are used in our Potable Water Systems.

Product Overview

Newterra Microfiltration and Ultrafiltration Solutions effectively remove abrasive TSS, turbidity and silt density index (SDI) constituents down to 0.01 microns allowing the recycling of valuable process fluids, such as coolants for tooling equipment. Used for wash water reuse, as well as providing a cost-effective approach to removing oil, grease, heavy metals and suspended solids from wastewater streams, Newterra ensures compliance with sanitary sewer discharge regulations.  Water and low molecular weight solutes (e.g. salts and some surfactants) are removed as permeate, while emulsified oil and suspended solids remain in the process stream and are removed as concentrate.

Features

  • Effective suspended solids filtration to 0.01 microns
  • Consistent permeate quality
  • Small footprint and skid mounted for easy installation
  • Reuse – savings on process water, mop water, coolants & cleaners
  • Cost-effective – reduced wastewater disposal or hauling costs
  • Can accommodate a wide range of feed water qualities
  • Modular – several units can be combined to address flow rate variations
  • Up to 98% recovery rates
  • Automated control & cleaning minimizes operator labor
  • Permeate flow rate controlled by a variable frequency drive (VFD)

Technical Specifications

Feed water is pumped or drawn via vacuum into the membrane skid and moves through the hollow fiber membranes. Water passes through and is sent to a permeate storage tank, but suspended solids are retained and build up on the membrane surface. Periodic membrane cleaning takes place automatically, using brief back pulsing, short-duration chemical cleanings or thorough chemical cleanings, depending on the increase in the trans membrane pressure.
