DFW Tank Cleaning near Waxahachie, Texas, plans to have its new 28,000-square foot, six-bay tank cleaning facility south of the Dallas-Fort Worth area in operation by the first of March, according to Randy Wasson, vice-president of Coal City Cob Inc, parent of the facility.
"Our facility is easy to access on I-35E at exit 404," says Wasson. "We will be offering services for dedicated foodgrade products, including kosher certification, as well as general chemical cleaning facilities."
One bay is isolated for foodgrade, four for chemicals, and the sixth will handle totes. Ben Kelley of OMK Enterprises, Mesquite, Texas, coordinated the project.
The facility typically has the capacity to handle 850 tank trailers per month with a maximum throughput of 1,000 per month. Starting off initially with handling Coal City Cob tank trailers for the first 45 days, the company expects to clean about 350 per month. After opening for commercial customers, the tank wash is expected to handle about 650 tank trailers per month.
Peacock Co Inc supplied the 60-gallon per minute single pass, non-recirculated unit that operates at 600 psi. The unit is skid-mounted.
Two tank cleaning bays for hard-to-clean products are equipped with a custom-built vat system supplied by Scott Services, Dallas, Texas. There are four 1,200-gallon vats, each preheated with 1 1/2-inch steam coils and utilizing a Superior Boiler Works 75-horsepower boiler provided by Tigert Boiler Works, Lancaster, Texas.
The wastewater system has three 12,000-gallon equalization aeration tanks and a custom-fabricated dissolved air flotation (DAF) unit that includes pH adjustment and monitoring, as well as polymer/flocculant injection. The system has the capacity to operate at 50 gallons per minute of continuous discharge, but will typically handle 20 to 25 gallons per minute. It is semi-automated and is equipped with a touchscreen and programmable logic controller (PLC).
Avia Environmental, LLC, Longview, Texas, directed the permitting process for the tank cleaning facility.
In addition to the wash rack on the site, Coal City Cob is in the process of constructing a transload facility that is projected to be in operation by early summer 2008. In addition, a 48,000-square-foot maintenance facility also is scheduled to open in 2008.
