Case Histories

L Shaped Tank Conforms to Irregular AreaL Shaped Tank Conforms to Irregular Area

Problem:

A major chemical company required 1,000,000 gallons of effluent emergency storage. The only available site was irregular in shape and could not accommodate the standard square or rectangular configuration.

ModuTank Inc. Solution:

An L shaped ModuTank with double membrane liners was custom designed and installed on the site on a turnkey basis.


Superfund Project Requires Long Term Storage

Problem:

A Superfund project required long term storage of 600,000 gallons of effluent and 300,000 gallons of clean water. Due to regulatory and contractual requirements, no permanent alteration of the irregularly shaped and severely constricted site was permitted.

ModuTank Inc. Solution:

Necessary capacity was supplied by three 15′ high round ModuStor tanks designed to fit the available area and installed on weather- resistant, steel alloy footing plate systems (patent pending) therby avoiding any alteration or penetration of the site.


Low-Cost Answer to Drilling Mud Pollution*Low-Cost Answer to Drilling Mud Pollution

Problem:

Drilling mud used to lubricate drilling bits during oil exploration was normally dumped into local waterways or otherwise discarded at the site after use. Increasing costs of the special muds and EPA restrictions against ground and water pollution necessitated practical containment for treatment and recycling.

ModuTank Inc. Solution:

Three ModuTank storage tanks with heavy-duty liners were installed – 500,000, 300,000 and 100,000 gallon units in respective capacities. Spent drilling mud is now pumped from the drilling rig to the larger collecting tank, and is introduced in measured volumes for settling in the mid-sized unit. The fluid then passes through a newly engineered treatment stage, and when processed enters the smaller tank, ready for reuse.


Tight Fit for Secondary ContainmentModuTank closely nested in a ModuTainer

Problem:

The plant structures of a major chemical producer left an unusually narrow corridor for providing storage and secondary containment for 900,000 gallons of corrosive, hazardous wastes. Time was of the essence.

ModuTank Inc. Solution:

Employing modular panels, a “form fit” ModuTank closely nested in a ModuTainer – both HDPE-lined – was simply and easily installed on the challenging site with ordinary hand tools. With rapid bolt-together assembly, the facility was securely on-line to meet critical operating schedules.


Modular Shape Meets Process Criteria*Cost-efficient S-shaped Modular Tanks

Problem:

A demonstration project for an innovative wastewater treatment process required two 800-ft. chlorine contact tanks, each handling a flow rate of one-million gallons per day. Linear tanks would be unacceptably long and less convenient to monitor.

ModuTank Inc. Solution:

Cost-efficient S-shaped units were easily customized through the modular capabilities of ModuTank’s flexible design concept. Two “folded” tanks were rapidly bolted together on location from prefabricated steel panels. Regarded as “ideal” for the demonstrations one-year phase, the tanks occupy readily-accessible compact sites adjoining the chemical handling building.


4,500,000 Gallons for Municipal Sludge Treatment*4,500,000 Gallon Tank for Municipal Sludge Treatment

Problem:

A process for safely transforming municipal sewage sludge into organic fertilizer depended on durable, long-lived holding tanks. Equally important were cost-effectiveness, fast shipment, and quick and easy field assembly.

ModuTank Inc. Solution:

During a three-phase, four-year program, the municipality installed three ModuTanks: one with 500,000 gallon capacity and two with 2,000,000 gallon capacity each. Both larger tanks were priced at less than 12¢ per gallon, and each were up and functional in under two weeks.


Large Capacity Storage Tanks for Fast Track Emergencies

• Power plant construction required 1,500,000 gallon storage of cooling tower water. To meet this need the initial 500,000 gallon EconoTank shipped the day after receipt of order; the follow-on 1,000,000 gallon EconoTank shipped one day later. The 500,000 gallon and 1,000,000 gallon EconoTank were installed and ready for use 8 days after the shipment.

• Military base remediation project called for holding 6,000,000 gallons of contaminated ground water prior to discharge. Two 1,000,000 gallon EconoTanks shipped two days after the receipt of order. Balance of four 1,000,000 gallon EconoTanks shipped weekly thereafter in accordance with project schedule. Client’s eight man work crew sequentially installed the EconoTanks in four days per tank.

• Refinery startup required 3,000,000 gallon effluent storage in order to meet contract requirements. Two 1,500,000 gallon EconoTanks were installed and on-line two weeks after receipt of order.


Temporary Storage for Site Remediation

Problem:

Sludge from a coal liquification project contained in a claylined pond was leaking hydrocarbons into a waterway and was threatening the local ground water supply. A serious environmental hazard existed.

ModuTank Inc. Solution:

The company’s contractor recommended and specified two ModuTanks, with a total capacity of 330,000 gallons, for temporary storage of sludge during site remediation. Although the original plan was to scrap the tanks after they had served their purpose, the plan was changed. Impressed with the Modutank’s functional advantages and speed of installation, the utility assigned the contractor to disassemble the units, clean their oil-resistant flexible membrane liners, and warehouse them for future applications.


“Overnight” Response Curbs EPA Penalties

Problem:

Oil spillage into a local river was subjecting a New York State company to steep environmental penalties of $70,000. A proposed oil/water separation system was required by a narrow site between a building and roadway. Speedy resolution of the situation was essential.

ModuTank Inc. Solution:

The company’s consulting engineer phoned on Friday, requesting a budget price for a customized 34,500 gallon ModuTank with a fitted, reinforced, oil-resistant flexible membrane liner with integral baffles. The tank was ordered on Monday, shipped Wednesday, received the next day, and fully installed in eight hours by five workmen with simple hand tools. By Saturday, the 19′ x 53′ ModuTank was fully operational in a tight location on a site requiring minimum preparation.


Relocation and Reconfiguration

Problem:

A government agency required a 500,000 gallon hazardous waste water storage tank for a Massachusetts Superfund site. Concurrently a 300,000 gallon ModuTank purchased previously by the same agency was no longer needed at a Superfund in Ohio.

ModuTank Inc. Solution:

The 300,000 gallon ModuTank was dismantled and shipped to the new site. Additional Modutank components were supplied and the tank reconfigured to the 500,000 capacity for use and subsequent relocation to a third site.


Flexible Answer for Groundwater Runoff

Problem:

Spent de-icing fluid flushed over aircraft at a major international airport posed a pollution hazard. A means of collection, storage and disposal was urgently required.

ModuTank Inc. Solution:

A series of low-cost ModuTanks, with 1.2 million gallons in total capacity, was strategically stationed to safely contain the fluid. The first four of the facilities were shipped within 72 hours of the order and delivered to the site 24 hours later. Owing to their modularity, the Modutanks were conveniently disassembled and later transported to other locales at the airport for similar service.


15 Tanks, Where Needed, As Needed

Problem:

An economical means of providing reusable, relocatable, easily assembled hazardous waste holding tanks was sought by a major waste treatment company.

ModuTank Inc. Solution:

Fifteen ModuTanks, each having a capacity of 50,000 gallons were supplied to the company’s various branch locations. These were then deployed as needed and subsequently relocated to other sites as required, thereby providing logistic flexibility.
