Rental Water Treatment Systems Support Industrial Wastewater Reuse

Forward-thinking industrial plants are treating and reusing their process wastewater. Industrial wastewater reuse is often a smart approach for economic and sustainability reasons. But what happens when the process wastewater treatment system needs routine maintenance or breaks down?

Unexpected downtime can force plants to scale back production or shut down altogether—at monumental expense.

To keep the plant online, plant managers typically bring in vacuum trucks, which draw the wastewater into the truck’s tank. From there, they either rent water storage tanks and store the water onsite or pay to have it hauled away and treated offsite. Both approaches add significant cost to the budget and may slow down operations.

Temporary water reuse solutions offer a practical alternative that can save time and money.

Benefits of rental water reuse systems

United Rentals offers fully customizable temporary water treatment installations that take the place of a permanent system until it’s back online. Built to specification, these installations offer several advantages over other stopgap approaches.

• Cost: All in all, temporary onsite water treatment is often the least expensive solution.
• Flexibility: Temporary solutions are customized based on which system components are down. Installations range from a single portable clarifier to complex solutions that mimic multiple components. They can be designed to address any number of water quality issues including suspended solids, oils, metals and organic contaminants.
• Speed: United Rentals can have a temporary water reuse system operational in as little as 24 to 48 hours to minimize disruptions and allow plant managers to maintain full production.
• Quality: The technology used is the same as or similar to the permanent system to ensure identical treatment quality and meet or exceed the performance of the permanent system.
• Scalability: These installations can be scaled to handle flow rates of up to 10,000 gallons per minute.

The United Rentals wastewater treatment advantage

Accurately specifying a water reuse solution is key to success. United Rentals can apply its deep knowledge of water filtration and treatment equipment and decades of experience to design the best system for the job.

The design process includes a series of important steps.

Detailed information gathering: United Rentals works hand in hand with plant managers to gather vital information including:

• Details about the current system
• The exact makeup of the process wastewater, including specific contaminants
• Expected flow rates, including peak and low volumes
• Water treatment goals
• Sensor requirements
• Requirements for integration with SCADA or other control systems
• Job walks: Job walks allow for the identification of potential tie-in points, planning for bypassing offline components and identifying space constraints that may require workarounds.
• Pump and filter sizing: Based on information provided by the customer, United Rentals can assist with critical calculations such as total dynamic head (TDH). Based on the TDH, United Rentals can provide pump curves to help the customer select pumps that can handle the required flow. They can also assist in sizing filtration equipment for the flow generated by the pump to ensure the rental equipment will deliver the results required by the customer.
• Onsite and 24/7 support: United Rentals offers end-to-end support to help keep the temporary system fully operational and troubleshoot any issues that arise.

Temporary process wastewater treatment solutions offer a cost-effective, flexible approach to keeping a plant fully operational when parts of the permanent water reuse system fail or need maintenance. A reliable vendor such as United Rentals can provide and implement a solution based on the customer’s specifications that limits downtime while minimizing expenses.
