With the SuperSkid approach, you can:

• Significantly reduce overall installation time and cost with multiple process areas on one skid
• Minimize space required to house process equipment of a given flow capacity.

Figure 1 below summarizes these benefits.



Figure 1.Benefits of the SuperSkid Approach. WPT customers receive a customized, water treatment solution that virtually "hits the ground running."

1.1 Significantly Reduce Overall Installation Time and Cost.

With WPT's SuperSkid approach, the field-erected, interconnecting piping is reduced by at least 50 percent. Interconnecting piping that is traditionally stick-built in the field is prefabricated and installed at WPT, giving the user totally-engineered, fitted, installed, and hydrostatically-tested piping as an integral part of the skid before shipping to the job site.

With other companies, by contract, actual system installed costs are unclear until it's often too late to change direction. WPT clearly identifies the number of equipment skids, the process equipment contained on each skid, and the items shipped loose, ensuring that the customer can accurately evaluate WPT's installed cost.

1.2 Minimize Space Required to House Process Equipment of a Given Flow Capacity.

Using the SuperSkid approach, WPT significantly reduces the space requirements of the water-treatment system, saving customers an estimated 20 to 40 percent in the combined cost of the real estate, building, foundation, and civil engineering services required to support the system. Figure 2 below graphically illustrates this space savings.

Unlike some industrial water treatment system suppliers, who place no premium on space utilization because the end user bears such costs, WPT minimizes this floor space by integrating multiple-process treatment modules within a single factory-manufactured skid. We provide a detailed physical layout of the proposed process equipment to allow the client to accurately compare the space requirements of our system versus our competitors.



Figure 2. More Leg Room. The SuperSkid approach saves as much as 40 percent of the combined cost of real estate and system support structure.

1.3 Reduce Interconnecting Wiring by 90 Percent, Saving up to 60 Percent on Electrical Installation Costs.

WPT provides all process-equipment modules as completely factory-wired and tested. Electrical wiring (analog and discrete conductors) within each SuperSkid will terminate in an enclosure and connect to a remote PLC within this enclosure. Each SuperSkid requires only 120 VAC source and a single, two-conductor, twisted pair cable to interconnect the various remote I/O panels to the PLC. The only additional wiring on a SuperSkid are motor leads from the power distribution, as applicable.

Electrical conduit runs, wiring termination, fittings, etc. will be reduced in like proportion. This approach virtually eliminates the need for field troubleshooting of interconnecting wiring, thus reducing the time period from equipment delivery to startup.

Unlike other providers, WPT offers each customer the ability to compare the total cost of field interconnecting wiring for our approach versus those of our competitors by providing:

• A detailed description of our control system.
• An estimate or table indicating the number, type, and size of interconnecting wiring conductors.

1.4 Dramatically Reduce Startup Time and the Cost of System Commissioning.

Each fabricated SuperSkid undergoes complete factory testing, including basic hydrotesting and dynamic operation under simulated plant-operating conditions as well as instrument calibration and testing at the factory. Any problems that arise during the testing phase are remedied in a more-timely manner in the factory than at the job site. WPT provides a detailed description of the scope and nature of factory testing, instrument calibration, etc. to facilitate comparative assessment of the total cost of equipment installation and startup in the field.

1.5 Save at Least Two Man Days with Factory RO Membrane Installation

WPT can install reverse-osmosis membranes on the SuperSkid at the factory, instead of at the job site. This allows dynamic testing of the system under simulated field-operating conditions, confirming the salt-rejection rate and revealing any problems, such as O-ring or brine-seal leakage. Solving these problems at the factory eliminates solving them during the system-startup phase. By supplying the system with factory-installed RO membranes, WPT eliminates the estimated cost to the plant for onsite installation as well as troubleshooting, which may result in costly repair downtime.
