Introduction
Sanborn Technologies provides membrane systems for waste minimization and resource recovery, particularly effective for wastewaters containing oily emulsions or fine suspended solids. These systems offer a reliable alternative to extensive physical and chemical treatments, providing environmental benefits by reducing energy use and eliminating airborne pollution.

Membrane Separation Process
Membrane separations utilize tight filters to separate smaller molecules like water from larger ones such as oil emulsions. Sanborn employs two main types of membranes: Ultrafiltration (UF) and Nanofiltration (NF), both known for their ease of use and reliability.

Ultrafiltration (UF)
UF systems are versatile, separating particles down to 0.005 microns. They are chemically resistant and can reduce waste by up to 98% without chemical additives. UF systems are ideal for applications like vibratory finishing and can produce sewerable effluent, significantly lowering disposal costs.

Nanofiltration (NF)
NF uses tighter membranes than UF, operating at pressures between 100-200 psi. It is suitable for low solids applications and requires prefiltration. NF is a middle ground between UF and Reverse Osmosis (RO).

Other Membrane Technologies
Microfiltration (MF) separates particles down to 0.1 micron and is used for suspended solids removal and metal hydroxide clarification. Reverse Osmosis (RO) is a high-pressure process for separating water from dissolved salts and metals, but it is not ideal for oily waste.

Membrane Configurations
Membranes are available in wide and narrow channel configurations. Wide channels are suitable for high solids applications, while narrow channels are cost-effective for waste streams without solids.

Applications
Membrane systems are used in various applications, including metalworking coolants, aqueous parts washer solutions, vibratory and deburring wastes, mop water, food processing wastes, air compressor blowdown, and printing press washwaters.

Sanborn Oil Separator (SOS)
The SOS is designed to remove free oils from wastewater efficiently, available in 5 GPM and 10 GPM configurations. It is compact, easy to install, and requires minimal maintenance.

Conclusion
Sanborn Technologies' membrane systems provide effective solutions for waste minimization and resource recovery, offering significant cost savings and environmental benefits.
