Mobile and Temporary Systems for Water and Wastewater

RapiSand for Mobile Treatment

Mobile Solutions to Bridge the Gap

Whether you have a planned maintenance event, a unique treatment need, or even a particularly challenging location WesTech has a full line of mobile equipment for rent.

For temporary water treatment, regulatory compliance, and even testing, we can optimize a mobile system to meet the unique demands of your site. Our containerized and skid-mounted units are modular and can be combined for systems that address larger flows and multi-stage treatment. Flexible contract time frames can be as brief as one month or as long as a year or more.

Mobile Clarifier Units

Support for Your Mobile Wastewater Demands

Temporary equipment provides a safety net from potential disruptions, especially for operations such as power plants, mine water, and refineries. When the unexpected happens at a plant – an equipment failure or a developing water shortage – mobile wastewater treatment systems provide a quick-response solution. Whether interruptions occur from emergency repairs or scheduled maintenance, they can cause the plant to lose revenue or fail to meet discharge regulations.

With mobile units, treatment requires a smaller commitment of resources and provides easier installation, fewer operating costs, a reduced environmental footprint, and an opportunity to test trial solutions before investing in full-scale installations. The systems can also include electrical, piping, asset management, and installation, based on process flow.

A temporary system can meet the transitional need for a fill-in treatment system when you are waiting to replace your aging plant with a newer one. Combined with an operations contract, a mobile and temporary system can provide a complete, turnkey package.

Featured Equipment

  • Horizontal Pressure Filter

    Our multimedia pressure filter efficiently removes heavy metals and turbidity. The filter includes multiple cells that allow for a self-generating backwash system that uses source water. This eliminates the need for a separate filtered water tank.

  • RapiSand™ Ballasted Flocculation

    WesTech’s RapiSand™ ballasted flocculation system is a high-rate clarification process that removes suspended solids by combining rapid mixing and multi-stage flocculation, followed by sedimentation. This trailered system includes hydrocyclones to provide separation of coagulated solids and microsand to recycle through the system.

  • SuperDisc™ Disc Filter

    The SuperDisc™ provides a large amount of filtration area in a small footprint. Each disc houses a polyester mesh that is used for liquid-solids separation. The SuperDisc is a low energy system with automatic backwash – all contained on a mobile trailer.

  • Dissolved Air Flotation (DAF)

    WesTech’s DAF is designed around the industry standard mobile frac tank with all main components pre-mounted. An air induction pump is used to float solids before they are collected, and a chain-and-flight system removes the floating solids off the top of the water.

  • Containerized UF

    Our containerized ultrafiltration units are designed with the same efficient and reliable low-pressure filtration that our regular installations provide. The containers protect and secure the membranes, making them easier to transport and install.

Also Available

  • Clarifier

    With a mobile, standard frac tank as a foundation, our clarifier provides liquids/solids separation and turbidity removal for primary and secondary clarification.

  • Aeration Tank

    Our mobile aeration tank incorporates a premium aeration design, modular setup, and easy operation. The diffusion header has multiple diffusion attachments that can be adjusted for different air requirements.
