Pressure Vessels & Screens

INDUSTRIAL WATER TREATMENT SOLUTIONS

As a dedicated industrial pressure vessels supplier, Sepratech provides a full range of pressure vessels and screens designed specifically for water and wastewater treatment across demanding process environments.Our portfolio includes pressure and gravity vessels for ion exchange, multi‑media and sand filtration, softeners, and activated carbon systems used in manufacturing, power, refining, petrochemical, and other industrial facilities.

Whether you are upgrading an older plant, expanding capacity, or replacing a single tank, we can provide in‑kind replacements that match your existing footprints and connection points, or supply custom-engineered vessels tailored to your process requirements. This approach minimizes installation work, reduces downtime, and helps you return critical systems to service as quickly as possible.

Sepratech vessels are used across a wide variety of applications, including:

• Filtration and Clarification

• Multi‑media and sand filters

• Turbidity and suspended solids control

• Pre‑filtration ahead of RO, UF/MF, and other membrane systems

• Softening and Ion Exchange

• Hardness removal for boiler feed and process water
• Demineralization and dealkalization
• Specialized ion exchange applications using cation/anion resins

• Activated Carbon & Adsorption

• Organics and color removal
• Taste and odor control
• Polishing filters for reuse and discharge applications

• Industrial & Utility Service

• Cooling tower make‑up and side‑stream filtration
• Process water conditioning
• Potable water treatment for facilities and campuses

If you are unsure which vessel configuration is best for your process, our team can review your flow rates, raw water quality, and treatment goals and recommend a practical, cost‑effective solution.

Every site is different. Sepratech offers a broad set of options so vessels can be configured around your operating conditions, space constraints, and maintenance preferences.

Typical configuration options include:

• Orientation & Style

• Vertical or horizontal vessels

• Pressure or gravity operation

• Single‑vessel systems or multi‑vessel trains for higher flow and redundancy

• Size & Capacity

• A wide range of diameters and shell heights

• Custom nozzle locations and manway sizes

• Designed to accommodate your media loading, backwash rates, and service flows

• Connections & Layout

• Inlet, outlet, drain, backwash, and vent nozzles arranged to fit existing piping

• Flanged, threaded, or grooved connections based on plant standards

• Tied into existing skids, manifolds, or structural supports where required

We work from your drawings, photos, and field dimensions, then match or improve upon your current layout to simplify installation.

The design of the internal distribution system is often the difference between a filter that runs well for years and one that struggles from day one. Sepratech engineers and supplies a full range of internals to support new builds, troubleshooting, and retrofits. We can provide, replace, or upgrade:

• Filter Nozzles & Strainers

• Wide selection of slot sizes and patterns for different media and flow ranges

• Configurations to reduce media loss during backwash and maintain bed integrity

• Screens & Wedge Wire Elements

• Wedge wire screens, slotted pipes, and screen‑wound components

• Engineered for low pressure drop and uniform collection/distribution

• Laterals & Header/Lateral Systems

• Custom‑sized laterals for even flow distribution across the entire vessel diameter

• Header/lateral arrangements designed to match your existing nozzle deck or support floor

• Underdrains & Support Floors

• Plate underdrains and monolithic floors

• Retrofit solutions to replace aging or damaged internals without replacing the entire vessel

These internal components can be supplied as stand‑alone items or as part of a complete vessel upgrade.

Engineered Solutions Tailored to Your Operation

We don’t offer generic equipment. Our team studies your process, reviews system performance, and designs solutions built specifically for your plant’s flow rates, chemistry, contaminants, and operational goals.

Comprehensive Inventory

From LAMELLA® clarifiers to pressure vessels, RO membranes, media, resins, and custom internals, we maintain one of the industry’s most complete equipment and parts inventories—all backed by technical guidance from experienced engineers.

Rapid-Response Rental Systems for Urgent Situations

When downtime isn’t an option, our nationwide rental fleet delivers fast support. Clarifiers, filtration systems, carbon units, and softeners are ready for quick deployment during outages, system failures, or temporary production demands.

Long-Term Support That Protects Your Investment

Our relationship doesn’t end at delivery. Clients rely on us for ongoing maintenance, media change-outs, membrane cleaning, troubleshooting, and optimization to keep systems running efficiently and compliantly over the long term.

Many plants operate vessels that are structurally sound but no longer deliver the performance they once did. Sepratech helps extend the useful life of that equipment through targeted maintenance and retrofit services. Our team can assist with:

• Inspection of existing vessels and internals
• Replacement of worn or damaged filter nozzles, screens, and laterals
• Upgrades to distribution/collection systems to improve flow balance
• Media removal, evaluation, and replacement (sand, anthracite, garnet, specialty media, or ion exchange resins)
• Custom retrofits to convert older designs to newer internal arrangements

These services are especially valuable when capital budgets are tight, but reliability and water quality requirements are increasing.

Need Help?

If you’re planning a new project, preparing for an upgrade, or troubleshooting ongoing water treatment challenges, our team is here to help. Contact Sepratech’s professional services team to discuss your specific requirements, review system conditions, and explore the options best suited to your operation. We take the time to understand your goals so we can offer tailored recommendations, engineered solutions, and accurate quotes designed around your facility—not generic templates. Reach out today and let us help you build the most effective, reliable solution for your industrial water treatment needs.

Sepratech has been supporting industrial water and wastewater operators since 1989. Over that time, we have worked with facilities in power generation and utilities, refining and petrochemical plants, chemical processing, food and beverage, general manufacturing, and other industrial and commercial process facilities. This extensive experience allows us to quickly understand the constraints you’re working under—limited outage windows, space limitations, existing piping, and production requirements—and propose practical solutions that can be implemented without disrupting day‑to‑day operations.

When you contact Sepratech, you are working with a team that is focused on industrial results, not just components. We can review your current systems, drawings, and operating history; identify bottlenecks, failure points, or recurring maintenance issues; recommend vessel replacements, internal upgrades, or media changes; and provide clear budgets and timelines so you can plan work around plant production schedules. Our goal is to improve efficiency, enhance reliability, and help you get more value from the equipment you already own.
