UST Replacement

USTLrgThis project was an underground storage tank replacement job in Salem, NJ. Carbonair provided four PC28 Carbon vessels behind a multi round bag filter. Carbonair partnered with Rain For Rent on this project, who supplied multiple weir tanks and pumps, a well point system, and additional bag filters.

This site was originally contaminated with BTEX by a leaking UST. This old tank had to be replaced with a new one. Since the contamination went as far down as 25 feet below the surface, a well point system was used to extract the water. The well points also helped to reduce suspended solids in the water coming into the carbon system. This is a good practice to ensure that the carbon beds are operating with the most efficiency and are not blinded off by solids accumulating on top of the carbon. The 400 gallon per minute system operated on site for about one month

USTSmlProject Specifics

  • Treatment flow rate: 400 GPM
  • Equipment Supplied: (1) multi round bag filter and (4) PC28 carbon adsorbers

Groundwater Treatment System Rental in Support of Highway Construction Dewatering

Hwy 100-2As part of a major highway improvement project, contractors had to dewater an area in order to pour footings for an overpass. Contaminated groundwater from an adjacent Superfund site was drawn into the dewatering stream, requiring treatment of the contaminated water stream prior to discharge on-site. Based on the large area being excavated, the high water table and the permeability of the soils, a flow rate of 3000 gpm was required to keep the excavation area dry during construction work.

Carbonair first met with the general contractor and environmental engineer to work out the required treatment system design and assess site logistics for system layout, delivery and installation.

Challenges for this project included:

  • High dewatering flow rate required (3000 gpm)
  • Small area on site for treatment system adjacent to operating highway
  • Short lead time for set up of system
  • 24 hour operation required

Carbonair designed and provided a 3000 gpm water treatment system consisting of three (3) individual 1,000 gpm treatment streams comprised of the following:

  • A 21,000 gallon settling tank for the removal of large solids and free product
  • Bag filters for the removal of suspended solids
  • Granular activated carbon (GAC) filters with 30,000 pounds of carbon for removal of dissolved organic contaminants.

The systems were provided with all necessary components for operation in the field, including 30 horsepower transfer pumps with level controls, hose and fittings, distribution headers and a 100 kW generator for the system’s electrical power requirements. The systems were mobilized, installed and started up in less than five business days from the notice to proceed. The actual field installation took three and one-half days.

The systems performed as designed and allowed the contractor to finish the installation of the footings ahead of schedule, saving them, and the DOT, a considerable amount of money. Carbonair was able to meet their short lead time for delivery of the system and was able to safely deliver, set up and then demobilize the systems in an extremely tight area adjacent to an operating highway and with overhead power lines at the site.

Demobilization was accomplished in just three days.

Groundwater Treatment System Rental in Support of UST Removal and Installation

3Carbonair was asked to provide a temporary groundwater treatment system to treat contaminated groundwater that was generated by dewatering performed in support of an underground storage tank removal and upgrade at a gas station in north Florida. In this case, the groundwater at the site was heavily contaminated with petroleum hydrocarbons (gasoline and diesel), which were present in dissolved and free product forms. The groundwater also had high concentrations of Arsenic and other heavy metals. Due to the high water table, the excavation area had to be dewatered at a rate of 500 gpm to allow for the removal of the old tanks and installation of the new tanks. Carbonair designed and provided an on-site groundwater treatment system for a maximum flow rate of 500 gpm.

A Carbonair field crew mobilized, set up, and trained the operators of the system. The system performed as designed, meeting the required discharge limits and treating the water generated at the site at the required flow rate. The use of diesel pumps and Carbonair’s diesel driven air strippers avoided the need for a costly power drop or expensive generator rental. At the conclusion of the project, Carbonair field technicians provided demobilization services including the extraction and disposal of the spent carbon and ion exchange filter media, and demobilization of the equipment.

Groundwater Treatment System Rental in Support of Manufactured Gas Plant Remediation Project

4The former coal gasification plant had operated from 1880 to 1950. The site (see top picture), located adjacent to a major river near a downtown area, was heavily polluted.

Contaminants associated with the old coal gasification plant (primarily coal tars) had seeped into the ground and migrated thirty feet below the water table, into the river sand deposits. Environmental clean-up of the site involved excavation and treatment of 50,000 cubic yards of contaminated soils.

Excavation of the contaminated soils from below the water table next to a major river presented significant challenges. One of the challenges included the requirement for an onsite water treatment plant capable of handling the dewatering discharge.

Carbonair furnished a 2000 GPM temporary water treatment system (see bottom picture) consisting of settling tanks, an oil/water separator and granular activated carbon vessels. Carbonair also furnished all of the required pumps and interconnecting piping.
The system was housed in a temporary sprung structure (shown being erected in the middle picture) during the winter months, to prevent freeze-up.

Groundwater Treatment System Rental to Treat Dewatering Water on Brownfield Construction Project

5A mid-Atlantic environmental firm contacted Carbonair to develop a treatment system for a Brownfield development project. Three office complexes were being built in downtown Washington DC. Each building included underground parking, requiring excavation 65 feet below grade.

Groundwater samples revealed BTEX and TCE contamination, and hydrological testing indicated pumping rates of 1000 GPM would be necessary to allow construction to resume.

Water treatment system design challenges on this project included:

  • A high water flow rate (1000 gpm)
  • Limited space on site for system
  • The need to move the system periodically to allow for site work
  • 24 hour operation required over a long period of time
  • The need to exchange media in vessels while maintaining a 1000 gpm flow rate
  • The potential need to downsize the system based on reduce flow rates in the future

 

For this project, Carbonair designed a modular 1200 GPM water treatment system consisting of twelve 100 GPM units on a common header. Each unit had a duplex bag filter skid and a Carbonair PC13 carbon absorber. Carbonair furnished the complete system, including hose, fittings, headers and valves. Carbonair’s field service team installed the system and trained the operating personnel.

  • This modular design allowed the system to continuously flow at 1000 gpm, while two vessels could be held in reserve and serviced if needed.
  • Using a modular system with multiple small carbon vessels resulted in less site preparation time prior to installation, when compared to larger vessels.
  • Due to extreme space restrictions, the system had to be moved several times during the course of the project. This was simplified by the compact, flexible design employed.
  • After 14 months of operation, site conditions changed allowing for a reduction in the required flow rate. Carbonair was able to easily reduce the size and operating cost of the system, by simply removing several of the 100 gpm modules.

As part of the remedy, contractors had to excavate and remove large quantities of soil at the source of the contamination. The soil and groundwater in this area were heavily contaminated with polycyclic aromatic hydrocarbons (PAHs), which were present in dissolved form and as free product. The excavated area had to be dewatered at a rate of 500 gpmduring excavation due to the high water table.

Carbonair designed and supplied a rental groundwater treatment system to meet discharge requirements, allow uninterrupted operation and have sufficient capacity to last throughout the excavation period — without media replacement.

Carbonair Field Technicians installed the system, performed system startup and trained customer staff in system operation. In addition, Carbonair provided 24-hour emergency on-call service.

The groundwater treatment system operated as designed on a 24-hour basis for the life of the project without any down time or media replacement required. As a result, the contractors were able to proceed with, and complete, the excavation of the contaminated soil without any delays —saving money and avoiding any costly permit violations.

Carbonair field technicians disassembled and removed the equipment and arranged for the disposal of the spent filter media, completing the “cradle to grave” solution to our customer’s temporary water treatment needs for this project.
