Mobile Filtration | WesTech Engineering

Innovative Mobile Systems for Water and Wastewater Filtration

WesTech’s mobile filtration units deliver flexible, on-demand solutions designed for both industrial and municipal applications. These systems support compliance, protect downstream processes, and improve overall water quality when permanent filtration systems are unavailable or offline.

Available on a rental basis, our temporary mobile filtration systems can be rapidly deployed and integrated into existing infrastructure. They are well suited for emergency response, seasonal treatment demands, planned outages, pilot testing, and project start-ups. They provide reliable filtration performance without the time or capital investment of permanent installations.

Unlike clarification, which targets bulk solids removal, mobile filtration serves as a critical polishing and barrier step. WesTech’s fleet supports multiple filtration approaches, including membrane and media-based technologies, to capture fine particles and biological material that impact cooling systems, discharge limits, and water reuse applications.

All systems can operate as standalone filtration solutions or be paired with clarification, reuse, and solids handling processes to support broader water treatment goals.

Our Mobile Filtration Offerings

Mobile Disc Filtration

Our mobile SuperDisc™ filtration units provide compact, high-rate water filtration in a small footprint. These containerized disc filters are designed for rapid deployment, they excel at tertiary polishing, reuse applications, stormwater treatment, and interim filtration support.

Key Advantages

Removes fine TSS down to 10 micron, and floc carryover for clearer, more stable treated water
Protects downstream UF membranes from fouling
Plug-and-play containerized packages with PLC controls for fast tie-ins

Mobile Pressure Filters

Our mobile horizontal pressure filters provide flexible particulate and targeted contaminant removal using multi-layered sand, mono-media, or greensand configurations. They are ideal for turbidity reduction, iron and manganese control, and polishing after clarification in industrial and municipal applications.

Key Advantages

Removes suspended solids, oxidized metals (As/Fe/Mn), and color/taste/odor
Pressure vessel with automated valving and backwash for fast, low-touch startup
Provides its own backwash, eliminating the need for a backwash storage tank and pumps

Mobile Reverse Osmosis

Our containerized, or trailered, plug-and-play reverse osmosis systems address dissolved-solids control, brackish/seawater desalination, and high-purity industrial water needs. Perfect for emergency potable water production, process/boiler makeup, ZLD pretreatment trains, and pond dewatering.

Key Advantages

Removes dissolved salts (TDS), hardness, silica, and metals
Delivers up to 700 gpm low-conductivity permeate for critical processes
Containerized skids with high-pressure pumps, VFDs, and onboard CIP

Frequently Asked Questions

What is the role of mobile filtration in water and wastewater treatment?

Mobile filtration gives you fast, modular polishing and barrier steps – removing suspended solids, metals, and microorganisms, and protecting downstream equipment – without committing CAPEX. It’s built for planned outages, emergency response, pilots, and capacity pinch points, then scales up or down as your needs change. WesTech’s lineup includes mobile disc filtration, pressure filters, gravity filters, ultrafiltration (UF), and reverse osmosis (RO), all engineered for rapid deployment and simple tie‑ins.

How does filtration differ from clarification?

Clarification removes bulk solids by settling or flotation; filtration captures the finer fraction and provides a tighter, more consistent barrier – often the last step before reuse or RO. Mobile clarification is used when you need high solids reduction at the front end, and through mobile filtration (disc, pressure, UF, RO) to hit final quality specs or protect membranes.

When should I use a mobile filtration system instead of permanent infrastructure?

Choose mobile systems when time, risk, or uncertainty are high: during plant maintenance, start‑ups, and emergency repairs; while validating a process change; or when you need compliance quickly but want to defer CAPEX.

WesTech’s mobile units are designed to be on site within days and run with minimal setup and training. Our units are available on flexible rental terms, so you can meet targets now and decide on permanent upgrades later.

What types of contaminants can be removed through disc filters, pressure filters, ultrafiltration, or reverse osmosis?

Use disc filters for polishing suspended solids and fine floc carryover; pressure filters (with the right media) for turbidity, iron, and manganese; UF for a consistent particulate and microbial barrier, delivering RO‑ready SDI (< 3); and RO for dissolved salts (TDS), hardness, and metals when you need high‑purity or desalinated water. Together, these mobile steps let you tailor removal to your feed and finish‑water targets – in a temporary, scalable platform.

How do filtration systems integrate with other mobile treatment options, such as clarification or softening?

We build temporary trains to match your water and permit: for example, DAF/clarification to knock down bulk solids, then pressure or disc filtration, then ultrafiltration (UF) to stabilize SDI, and finally reverse osmosis (RO) for dissolved salts or high‑purity needs. For high‑TDS or ZLD applications, we’ll pair softening and filtration ahead of RO to protect downstream thermal equipment or to concentrate salts for near zero liquid discharge. All of these steps are delivered in mobile, plug‑and‑play modules that tie in quickly on site.

What level of treated water quality can be expected from each mobile filtration technology?

Disc and pressure filters reduce turbidity and suspended solids; pressure filters (with proper media and oxidation) also target iron and manganese for clear, stable effluent. UF provides a consistent particulate and microbial barrier and is sized to deliver RO‑ready SDI (typically < 3) so you can run higher recoveries with fewer fouling events. RO then removes dissolved salts (TDS), hardness, and many metals to meet high‑purity or desalination targets. Final guarantees depend on feed quality and run conditions; we’ll size media, membranes, and chemistry to your analysis and operating goals.

How does WesTech ensure mobile filtration units meet compliance for potable water and wastewater discharge?

Compliance starts with the right process train and pretreatment – softening, clarification, filtration, UF, and RO are combined as needed to hit your permit or drinking‑water specification. Our containerized systems are engineered for rapid deployment and reliable operation, backed by ISO‑aligned quality processes and industry experience supplying regulated markets like power and municipal water. We commission on site, train operators, and can provide monitoring and operation services so you stay on spec throughout the rental term. The equipment is built with NSF approved wetted materials and coatings.
