Ultrafiltration Large Series
Brochure Download
SANBORN’s UFV Series of Ultrafiltration systems bring compact wastewater disposal/reuse technology to manufacturing facilities. Designed for waste volumes of up to 1,500 gallons per day (GPD), these economical systems allow for simple, continuous operation with a minimum of energy and operator involvement. All UFC systems employ ultrafiltration membrane technology to separate water and dissolved chemicals from suspended solids and emulsified oils. The process reduces wastes by as much as 98% without the use of chemical additives!
The separation process is mechanical and operates without messy and expensive pre-filtration and, in most cases, produces a reusable or directly sewerable effluent thus dramatically reducing waste of disposal costs.
Models are shipped pre-wired and pre-piped for easy installation. Options include an integrated free-oil separator, automatic fluid transfer system, flushing shutdown system and packaged water reuse designs.

Frequently Asked Questions
Ultrafiltration, often called U/F, is a membrane-based wastewater treatment process used to separate water from larger contaminants in water-based solutions, emulsions, and suspensions. Under pressure, water passes through permeable membrane elements while larger materials, including emulsified oils, fine solids, and other suspended contaminants, are retained and concentrated.
The clarified permeate can be collected for reuse or discharge when it meets the requirements of the application and applicable regulations, while the concentrated waste is managed separately.
Ultrafiltration is generally suited for water-based industrial waste streams containing suspended solids, colloids, emulsified oils, burnishing soap, coolants, cleaners, and similar process contaminants. It can be used in mass finishing, cleaning, machining, and related manufacturing operations where aqueous wastewater must be treated before reuse, discharge, or off-site disposal.
Bel Air can review the wastewater stream, contamination level, daily volume, and reuse or discharge requirements to determine whether ultrafiltration is appropriate.
Yes. Ultrafiltration can reduce wastewater volume and produce clarified permeate that may be collected for reuse in an appropriate process or directed to discharge when it meets site-specific and regulatory requirements.
Whether treated water is suitable for reuse depends on the original wastewater stream, the required water quality, and whether additional treatment is needed. Bel Air can help evaluate the appropriate configuration for recirculation or disposal.
The Large Ultrafiltration Series is a skid-mounted, single-pass wastewater treatment system that circulates process fluid through wide-channel tubular membrane elements under pressure. Water passes through the membranes as clarified permeate, while solids, colloids, emulsified oils, and other retained contaminants remain in the process stream and become increasingly concentrated.
Crossflow filtration helps keep solids moving through the membrane elements and helps discourage fouling. The tubular configuration is designed to process wastewater containing suspended solids and emulsified matter without relying on chemical additives as the primary separation method.
Clarified permeate is directed to a 200-gallon storage tank or to a drain when permitted. The storage tank can include a supply pump and dispensing valve to return treated water to the process as needed. The concentrated waste stream is managed separately.
For unattended operation, the system’s recirculation pump automatically shuts off if low-pressure or high-temperature conditions are detected. Periodic membrane cleaning with a mild alkaline washer solution helps maintain performance.
The Large Ultrafiltration Series includes systems with nominal capacities of 250, 750, and 1,500 gallons per day. Actual daily throughput can vary based on the condition of the wastewater, including solids concentration, oil or emulsion content, temperature, and the required level of treatment.
The series is designed for larger-volume industrial wastewater applications where unattended operation and reduced operator involvement are important.
Large Ultrafiltration Series systems use tubular membrane elements and crossflow filtration to separate solids, colloids, emulsified matter, and oily emulsions from the wastewater stream. The wide-channel tubular configuration is designed to accommodate solids and help discourage membrane fouling during processing.
The ultrafiltration process uses membrane separation rather than chemical additives to concentrate the waste emulsion and solids. Clarified permeate can be directed to the included storage tank for reuse or to a drain when permitted, depending on the application.
Yes. The Large Ultrafiltration Series is designed for unattended operation and includes controls in a single enclosure. For protection, the recirculation pump automatically shuts off under low-pressure or high-temperature conditions.
The skid-mounted systems are pre-piped and pre-wired to support installation, although periodic membrane cleaning and normal system inspection are still required.
Membrane cleaning frequency depends on the wastewater chemistry, solids concentration, oil or emulsion content, operating hours, and the volume processed. Periodic cleaning with an appropriate detergent or mild alkaline cleaning solution helps remove buildup and maintain consistent membrane performance.
Large Series systems use tubular membranes designed to process higher-solids wastewater streams, but cleaning and replacement intervals should be based on actual operating conditions, permeate flow, pressure, and treatment performance. Bel Air can recommend an appropriate maintenance approach based on the wastewater stream and system configuration.
