WRS - Wastewater Recycling System

The Right System For Wastewater Filtration Problems

FSI offers both microfiltration and ultra-filtration systems for wastewater treatment. The WRS filtration system is designed to treat oily wastewater and process fluids. The system produces clean water that is typically suitable for reuse or discharge, while concentrating organic and inorganic contaminants down to less than 10% of the original waste volume. This meticulously designed system exhibits the flexibility to handle a wide array of waste feeds including both free and emulsified oils. These systems are designed to treat/recycle wastewater from various sources such as rinse, process, and wash water to comply with local discharge regulations and RCRA requirements or to be recycled for maximum savings. 

Wastewater Recycling System P&ID

There are two major cornerstones in FSI’s WRS Wastewater Recycling System for oily wastewater recycling applications. The first key development is the integration of FSI’s process knowledge into pre-packaged systems targeted specifically at recycling applications. A full range of systems have been engineered and sized to fit the most common washer sumps (50 to 10,000 gallons). 

The second and most important key to the success of these recycling systems is the application of hydrophilic membranes which is highly resistant to fouling by both tramp and emulsified oils.  The membranes come with a hollow fiber configuration, which has the advantage of structural strength over conventional sheet membranes, i.e. no issue of delamination. In addition, the pore size and morphology of the membranes have been designed to ensure complete passage of recycled components (e.g. water and cleaners) while retaining greater than 99.9% of the oils. All these robust properties allow FSI’s membrane to successfully endure the harsh process environment of parts washing facilities. 



Super Hydrophilic Membranes

  • Resists oil fouling
  • Handles up to 60% free oil
  • Provides high/stable output over the life of the membrane

Solvent Resistant Membrane

Compatible with most hydrocarbons, free oils, acids, and the expansive class of polar organic solvents used in many industrial plants, the Super Hydrophilic membrane can operate at temperatures up to 170° F and is stable through a broad pH range from 2 to 12

Specially Designed Membrane for Parts Washing Applications
