Port Authority Wash System Case Study

transportable equipment room for port authority

Problem: An international engineering design firm working with a Port Authority contacted us to help them design an equipment and truck wash. The Port had an old wash pad that was too small and old wash equipment that no longer worked very well. The Port needed a larger pad and updated washing and water treatment equipment to accommodate the washing of their existing fleet.

They had the option of either building the wash system with either a closed loop wash water treatment system or a sewer discharge treatment system since they had sewer access but it was quite a distance to the sewer connection.

Solution: Wash Bay Solutions helped the engineering firm develop the design for the wash pad, solids settling system, the wash system and two options for water treatment. For both options, we designed the wash and treatment systems to be installed in a portable transportable equipment room to make it simple and cost effective to install. Requests for Quotations were put out for both options and the electric hot water pressure washing system with the SPT-10 Clarifier oil water separator for sewer discharge turned out to be the most cost effective for this particular location with in the port.

We coordinated with the construction company while they were building the wash pad, settling system and sewer connection line. When they were ready, we shipped up the 20’ transportable equipment room (TER-20) and helped them install it in place and get it up and running within a couple days time!

Why Do I Need a Re-Cyke® TWB System?

These complete wash systems are ideal for washing equipment and vehicles at sites without incurring any construction costs, delays, or permanent structures. Used on military bases, construction sites, and at any facility requiring transportability, these cost effective systems can be configured for a wide range of applications and up and running in a few weeks. Recycling wash water also eliminates EPA and local impact fees, reduces sanitary sewer costs, and water restrictions.

How Does the Re-Cyke® TWB System Work?

The complete system consists of a self-contained aboveground wash pad and an enclosed equipment room. The pad includes a 12” high ramped structure capable of handling up to 40 tons/axle and tracked vehicles, an integrated water collection system to isolate solids and divert liquids, and a solids wash-down feature. The enclosed equipment room sits adjacent to the wash pad and contains complete water recycling, high-volume demucking, and high-pressure washing equipment.

As vehicles are cleaned on the pad, the wash/rinse water collects beneath the pad and is transferred to the closed loop recycling system for treatment and reuse so there is no off-site discharging. The solids removed from the vehicle are automatically washed to a collection section for future removal and disposal.

Location: Eastern Tennessee

PROBLEM: A rural large distributor of construction and mining equipment was cleaning their equipment on an uncovered wash pad. The combination of the equipment washing and rain water accumulation often caused the pad to overflow into a nearby canal, creating environmental concerns. The company was seeking a solution that would eliminate the overflow problem, completely recycle all their wash water, and require minimal new site construction. They also needed a system that would be easy to move since their corporate officials were looking at new facilities.

The customer needed two types of cleaning systems – high volume washdown for heavy solids removal and hot water pressure cleaning for grease and oil removal. The facility also needed a completely self-contained water recycling system since there was no sewer connection and rainwater detection and water level controls to eliminate the wash pad overflows.

SOLUTION: The site was an excellent candidate for the WWMI TWP System – a transportable equipment room containing all washing and recycling equipment needed to completely collect, store, treat, and redeliver the water for all cleaning requirements.

The 40-foot modular equipment room contained a 20 GPM, 300 psi Demucking System, a 4 GPM, 3000 psi electric hot water pressure washer, closed loop recycling system with 1500 gallons of processed water storage, and a Rain Detection System (RDS). The entire Transportable Wash Bay (TWB) System was shipped intact and pre-tested, enabling the client to rapidly put it into operation. The integrated RDS System provided for the capture of all contaminants in the water during a rain event, and allowed only clean storm water to divert to the adjacent canal.

DATE INSTALLED: February 2009

RESULTS: The client has utilized the system without any environmental or operation problems for over 1500 hours/year. They use the Demucking System 80-85% of the time to clean their equipment, minimizing the need for high pressure. The adjacent canal is now clear and pollution-free.
