EASY-ASSEMBLY RESTROOM
PolyJohn Enterprises Corp. unveiled a new restroom design that aims at greater strength and rigidity in a unit that can be assembled easily with a few tools and the fewest possible fasteners. The yet-unnamed-restroom model has some of the same convenience features as the longstanding PJ3 restroom, but has been engineered with a stronger base, corners and roof. Most of the components can be snapped together, while the unit has only two rivets, used to attach the toilet paper dispenser. The restroom replaces a traditional one-piece skid with four feet that are anchored from all sides for greater strength. The roof is rotational molded, the door has a twin-sheet thermoformed design, and many smooth interior surfaces promote easy cleaning. The corner tank placement makes a roomier cabin and minimizes spillage in the event of a tip-over.

The Sunrise door is 27 1/2 inches wide, 4 inches wider that previous restrooms, and features a three-roll toilet paper holder and a shelf with an integrated coat hook.

Using a mitigating tank system, instant water heaters and a simple mixing valve design, the unit provides consistent 101-degree water, 20 pounds of water pressure and a 1.5 gpm flow. A pushbutton control provides a measured amount of water, preventing depleted freshwater supplies due to a valve being left open. Showerheads have a variety of massage features.

The triple-axle trailer has an aluminum exterior. 574/892-5151; www.ameri-can.com.
DEBRIS COLLECTOR
Imperial Industries Inc. introduced its Aluminum Debris Collector for screening septage and portable sanitation waste at the tank discharge. Though aimed mainly at septage land application users, the tank with a 3-foot stainless steel screening comb can also be used for initial screening of waste being transferred to a storage tank. Once the unit is mounted to a truck via 2-inch receiver bars, waste runs through a 6-inch inlet and is screened through the comb with 3/8-inch teeth. Trash is trapped by the comb and the tank can be periodically cleaned through an end cap. The unit has grab handles for easy installation. The manufacturer builds a variety of spreading pans at angles to match different discharge configurations. 800/558-2945; www.imperialind.com.

Wastewater enters the 4-inch inlet pipe and is infused with air from the submersible aerator pump at the bottom of the aerobic treatment plant. The venturi created by the pump pulls fresh air from the surface and mixes it with effluent in the bottom of the tank.
