Filter Systems for Surface Finishing

Palm Technology supplies a full line of filtration systems engineered to meet the exacting needs of surface finishing operations. We offer systems designed for bag, cartridge, disc, and high-flow filtration, each built to handle aggressive chemistries, variable particulate loads, and continuous-duty cycles. Partnering with leading manufacturers like WARCO, we deliver filtration units that support consistent bath quality, extend solution life, and improve overall plating performance.

Bag Filtration Systems

Bag filtration systems are an excellent choice for general-purpose filtration in plating, cleaning, and wastewater processes. These systems use replaceable felt or mesh filter bags and are ideal for operations where large volumes of particulates need to be removed quickly. Available in single- or multi-bag configurations, they are easy to maintain, cost-effective, and work well in high-flow applications. Palm supplies bag filter housings in polypropylene (PP) for most acid and alkaline solutions, PVDF for high-temperature or highly aggressive chemistries, and stainless steel for solvent or oil-based systems.

Cartridge Filtration Systems

Cartridge filters offer finer filtration capabilities and are ideal for sensitive processes where clarity and particle control are critical—such as electroless nickel, precious metal plating, and final rinses. Cartridges come in various lengths and micron ratings and can be used in single or multiple housing arrays. With options for absolute or nominal-rated cartridges, these systems provide precision filtering in compact, efficient packages. Palm offers housings in PP for standard chemistries, PVDF for corrosive fluorides or strong oxidizers, and stainless steel for solvent compatibility.

Disc Filtration Systems

Disc filters are a compact solution well suited to small tank volumes or processes requiring continuous operation in tight spaces. These systems use stacked filter discs to trap particulates while allowing for easy maintenance and quick media changes. Disc filtration is popular in decorative plating, lab-scale systems, or where mobility and footprint are considerations. Like other filtration types, disc units can be configured in PP, PVDF, or stainless depending on chemical compatibility and operating temperature.

High-Flow Filtration Systems

For large tanks, high circulation rates, or systems with heavy particulate loads, high-flow filtration systems offer unmatched throughput and durability. These systems use oversized bag or cartridge elements to handle high volumes with lower pressure drops, reducing maintenance and increasing efficiency. High-flow systems are common in zinc, chrome, or phosphate lines where solution turnover is critical. Palm custom-engineers high-flow units in thick-walled PP or PVDF for chemical resistance or 304/316 stainless steel for heavy-duty mechanical environments.

Material Selection for Chemical Compatibility

The right filtration material is critical to long-term system performance. Polypropylene is the industry standard for many acid and alkaline chemistries, offering good chemical resistance and cost efficiency. PVDF is used when higher temperature stability or resistance to aggressive acids like chromic or nitric is required. Stainless steel is chosen for processes involving solvents, oils, or where mechanical strength and high-pressure operation are needed. Palm engineers will evaluate your specific chemistry, operating temperature, and flow rate to recommend the best material of construction.

Full Integration and Support

At Palm Technology, we don't just supply filters—we ensure they work seamlessly within your entire process system. From pump and filter pairing to automation controls and tank layout, we offer complete integration support. Whether you're replacing an old filter unit or designing a new turnkey plating line, we make sure your filtration system is sized, selected, and built for reliable performance.
