[Diagram Details Below]

Stainless Steel Inlet Compartment – The water is pumped into the system through a non-clogging diffuser pipe to distribute the flow. The inlet chamber is designed to reduce suspended solids, dissipate energy and begin separation.
Sump Pump – Water is pumped into the system via an air diaphragm sump pump.
Inclined Plates – Inclined plates above the sludge chamber catch suspended particles as the water stream moves into the separation chamber.
Separation Chamber – After the water travels up the inclined plates, it flows into the stainless steel separation chamber containing the coalescing media.
Coalescing Media Packs – The high efficient coalescing pack in the separation chamber further slow the water velocity so oil drops out of suspension and clings to the media. This media will remove 99% of free oil droplets 20 microns or larger.
Oil Skimmer – The oil that has dropped out of suspension is then skimmed off the top of the separation chamber and into a tank for easy removal.
Baffles – An underflow weir will prevent re-suspension of solids while an oil retention weir will keep the oil in the separation compartment.
Ozone Generator – The water is injected with ozone to kill odor-causing bacteria.
Clean Water Chamber – The third stage is a clean water chamber where the clean water will flow out for reuse to the drain.
Float Control System – SPT Series Systems come with optional control systems for simple, automatic operation.

Oil and Water Separator — Truck Repair Facility uses the Oil Water Separator to recycling the oily water when the trench was full.

Location: Morganton, NC

PROBLEM:
The facility had an old oil water separator system that was no longer working well. City environmental officials had visited the facility and mandated that the facility install a new system.

Since this facility was discharging to the city sewer system, city officials gave them a very short period of time to correct the situation.

SOLUTION:: Using their existing trench system, we designed an automatic pump transfer system that would transfer the oily water to the new oil water separator when the water in the trench got to a certain height.

Since time was an issue, we modified our production schedule to meet the city’s installation date demands. Funding was also an issue so we also worked with a leasing company to secure a simple, short-term equipment lease for the customer.

DATE INSTALLED: May 2008

RESULTS:Customer is very pleased with the system and city environmental officials are happy with the effluent from the oil water separator.

Oil Water Separator used for truck service company

Location: Sanford, NC

PROBLEM:
A major truck services company was constructing a new wash bay at their facility outside city sewer limits. They enlisted our help to design and install a closed loop system so they could recycle the wash water.

SOLUTION: : After visiting the site and talking with the service manager, we met with the local POWT officials who approved our Model VR/SPT-10 closed loop system for this location. We then met with the design engineers and construction managers to develop and efficient wash bay design for their busy wash operations.

The VR/SPT-10 closed loop recycling system is a complete self-contained system, capable of feeding up to 10 gpm to the pressure washer. It incorporates an extremely efficient patented filtration process utilizing fully automated solids filtration and activated carbon (GAC) polishing filtration. The VR series also comes standard with a corona discharge ozone generator to prevent odors. The clarifying oil water separator section will remove all settable solids and non-emulsified oil from the waste stream. All features of the system are designed and constructed to insure superior performance and minimal operating requirements while delivering a superior quality wash water.

DATE INSTALLED: May 2007

RESULTS: The client is extremely pleased with the equipment and the overall relationship. We also provide a monthly inspection of the system which helps the service personnel maintain the system more efficiently.

Sewer Pretreatment System — Forklift Dealer has an SPT-10 Sewer Discharge System installed.

Location: Springdale, AR

PROBLEM:
During construction of a new wash bay facility, a forklift dealer/distributor enlisted our help to design a wash bay and install a sewer pretreatment system. While testing the SPT-10 Sewer Discharge System for the initial start-up, we discovered that the wash bay sump pit had a slow but potentially dangerous leak. This leak, if not corrected, would have lead to groundwater contamination with oily waste water and wash water from batteries. This deficiency had to be corrected prior to use of the wash bay.

SOLUTION: The fix needed to be permanent and 100% effective to protect the customer’s interests. If a leak contaminated the ground water and associated soils, clean-up could cost tens of thousands, if not hundreds of thousands of dollars.

Several solutions were developed including lining the sump with a water-proof grouting material, installing a stainless steel liner in the sump, and re-pouring the concrete. After analyzing all of the solutions, they decided that the water-proof grouting option would provide the best protection for the money.

DATE INSTALLED: April 2007

RESULTS: Since the problem was caught before washing operations commenced, no dirty, oily water leaked into the groundwater and no contamination occurred. The customer is very happy with the sewer discharge system which was designed to automatically pull water from the sump.

Location: Cary, NC

PROBLEM: This project was unique in that it was located in one of the strictest wastewater authorities in the state of North Carolina. During construction of a new wash bay facility, a major heavy equipment dealer/distributor enlisted our help to design and install a sewer pretreatment system.

OPERATING REQUIREMENTS: Required sewer pretreatment water recycling systems, 10-gpm flow rates with odor elimination; minimal system maintenance; fully automated filtration operation; large volume oil removal capability, heavy solids handling capacity, high-volume hot water pressure washing and 30-gpm demucking equipment.

SOLUTION: After visiting the site and talking with the service manager, we met with the local POWT officials who approved our Model VSD/SPT-10 sewer pre-treatment system for this location. This system is a complete self-contained system, capable of feeding up to 5 GPM to the pressure washer. It incorporates an extremely efficient patented filtration process utilizing fully automated solids filtration. The VSD series also comes standard with a corona discharge ozone generator to prevent odors. The clarifying oil/water separator section will remove all settable solids and non-emulsified oil from the waste stream.

Model VSD/SPT-10 sewer pre-treatment system — Sewer Pre-Treatment System used for the case study.

Following installation, we completed the permit application for our customer and coordinated the filing with the city officials. Due to the complex permit requirements, we met with the local POWT officials several times during the construction period. As a requirement of the permit, the city required a $3,000 non-resettable, non-contact water meter. After numerous communications, we convinced the city that a $800 unit would work just as well – saving our customer $2,200 on a water meter!

DATE INSTALLED: December 2004

RESULTS: The client is extremely pleased with the equipment and the overall relationship. We now help coordinate the permit-required monthly water analysis for our customer – and they have been well within compliance limits every month. In fact, the City of Cary dramatically reduced our testing requirements after a couple years due to the consistently good analytical results indicating low Oil & Grease and Metals’ levels as well as low daily volume discharges.

PERIODIC MAINTENANCE REQUIRED: Averages 5 man-hours/month

ANNUAL PARTS AND FILTER COSTS: Approximately $1100
