Cooling Tower Blowdown Reuse DOW UF Membranes SFP-2860XP / SFD-2860XP PVDF Module 51 m2 High Flux

Industrial facilities with large cooling towers continuously discharge blowdown to control dissolved solids, and in water-stressed regions every cubic meter of that discharge is a lost resource. Treating blowdown with UF followed by RO allows the water to be recycled back to the cooling system, cutting makeup water demand by up to 80 percent. The DOW UF membrane SFP-2860XP / SFD-2860XP module is built for exactly this duty: high flux, compact footprint and the fouling resistance needed for cooling water containing corrosion products, scale particles and microbiological debris.

The XP high-flux version of the IntegraFlux 2860 module delivers 2.0 to 8.5 m3/hr from a 51 m2 PVDF fiber bundle while operating in the simple outside-in dead end mode. Because cooling tower blowdown chemistry varies with cycles of concentration and treatment chemicals, the module's wide pH tolerance and robust fiber construction keep the pretreatment rack reliable through every seasonal condition.

• High flux XP technology: the enhanced-permeability fiber delivers up to 8.5 m3/hr per module, minimizing the number of vessels in retrofit projects.
• Compact 51 m2 footprint: the 8-inch module fits existing UF racks and tight utility areas inside power and industrial plants.
• Removes foulants before RO: 0.03 um filtration strips suspended solids, corrosion products and biofilm particles from blowdown before the RO stage.
• Chemical-tolerant fiber: PVDF construction with pH 2-11 tolerance supports the scale-inhibitor and biocide-laden water typical of cooling systems.
• Automatic operation: dead end filtration with periodic backwash and air scour keeps the system running with minimal operator attention.
• Light and easy to handle: 48 kg empty weight simplifies module replacement in confined plant rooms.
• Proven industrial record: the IntegraFlux XP platform is widely installed in power plants, refineries and chemical facilities for water recovery.

Cooling tower blowdown reuse systems couple the SFP-2860XP modules with RO to recycle blowdown as cooling makeup. The UF step protects the RO from the particles, iron corrosion products and biofilms that accumulate in recirculating cooling water, enabling RO recovery rates that make the recycle loop economically attractive. Such systems are installed in steel mills, petrochemical plants, data centers and combined heat and power facilities.

The module is also used for side-stream filtration of cooling water, pre-treatment of river or pond makeup water and wastewater recycling in utility plants. Our engineers size the UF rack, select the backwash regime and calculate the water balance so that the cooling system's cycles of concentration stay within design limits.

SFP-2860XP / SFD-2860XP modules are supplied wet with sealed end caps in individual export packaging, complete with factory test certificates and handling instructions. Stock modules are available within 5-8 working days, and project quantities are produced to confirmed schedules.
