Even though the terms “Oil Interceptors” and “Oil Water Separators” are often used
interchangeably, they are very different systems.

Interceptors

Oil interceptors are typically used in low flow drain lines where small quantities of oils, sediment
and other liquid contaminants can be “intercepted”. These drain lines may come from variety of
facilities including covered parking garages, machine shops, service stations, and manufacturing
facilities.

Usually constructed of steel, fiberglass or plastic, interceptors are simple systems which include a
baffle plate, a solids bucket, and a separation area. As the water enters the interceptor, a baffle
plate reduces the flow and turbulence of the incoming water which helps to drop out some solids
and sludge.

A low flow rate and little turbulence permits the oils and other light density to slowly separate from
the water and rise to the top of the separation area. From there, relatively oil-free water is
discharged to the sewer.

Oil Water Separators

In comparison, Oil Water Separators have a far more sophisticated and efficient design. They are used in higher volume applications such as industrial wash operations, parking lots, re-fueling facilities and military installations where there is a potential for a much higher volume of water, oil, and contaminants.

The standard oil water separator is a steel or stainless steel tank containing an inlet compartment, baffles system, sludge chamber, separation chamber with coalescing media, and clean water outlet chamber.

The water enters the inlet compartment where the oil separation process begins. Here, baffles slow down the water flow which causes some of the solids to drop out of suspension. Next, parallel corrugated coalescing media in the separation chamber cause the oil droplets in the water to coalesce together, and increase in size until they separate from the water. This coalescing media, with an internal structure of interconnecting channels, can remove essentially all free and dispersed, non-emulsified oils to an effluent concentration of less than 5 ppm – which is acceptable for discharge to most municipal sewer systems.

During the winter as winter storms approach, many municipalities will spread salt directly on the roads. Additionally, many have started to proactively apply what are called anti-icing fluids to prevent water from forming frost on the pavement surface. Whether anti-ice or deicing fluids, they all share the same basic chemistry, which is some form of salt. The formulations include sodium chloride, calcium chloride or magnesium chloride. Additionally, the anti-icing fluids often include organics such as beet juice or cheese whey.

This presents a unique issue for winter washing operations, especially when closed loop wash water treatment systems are employed. Closed loop wash water treatment systems are used in a variety of instances including no access to public sewer systems, unreasonable permitting issues associated with sending water to the sewer, and uneconomic costs to tie into a sewer system due to the distances.

When cars and trucks are driving on roads coated with either deicing or anti-icing fluids, the vehicle’s body will often become covered with a thin coating of salts. During typical washing operations, the salt is flushed off. If the wash bay is connected directly to a sewer, that salty water is diluted and simply sent to the city without issues. However, if the wash system is connected to a closed loop system where that water is used over and over, the salt levels will continue to rise in the wash waters. This leads to the salt being reapplied to the vehicle, which show up as salt streaks when it is dried. But more important than the streaks, the salt residue enhances the corrosion process on the metal.

There is no simple or inexpensive way to remove salts from wash waters. One option is to haul off or send a portion of the salt contaminated water to a city sewer. Another option is to use a thermal evaporator to continually evaporate a small amount of the water in the closed loop system’s volume so that fresh water can be added. Periodically, the concentrated water and salt mixture in the evaporator would also have to be hauled off. The evaporation process will reduce the total volume of waters to be hauled off, and hence, reduce the hauling cost. The third option is to use a membrane filtration system. However, this method is expensive and not at all well suited to process waters contaminated with dirt, dust, cleaning chemistries, and oils.

The salt in the waters also has implications for the components of wash water treatment systems. Although our oil water separator system is constructed of 304 stainless steel, salts in the water may attack the welds in the unit and accelerate the corrosion process. Additionally, salts will attack pump shafts and cause the seals to leak. If this happens, the only solution is to change the pump.

To combat the effects of corrosion, we offer various levels of corrosion protection to our clients. For our oil water separators, we offer an internal coating which forms a tough barrier that protects the stainless steel from the salt. For our other treatment systems, we can upgrade the pumps from carbon steel to a salt resistant 316 stainless steel, which will prevent any pitting of the shafts and pump internals. We can also add a conductivity meter to continually monitor the amount of salts and other chemicals in the water and trigger an alarm when the levels rise too high. Once this water is pumped out or discharged, fresh water is automatically added to the system, diluting the salts to a manageable level.

System Components

Geo Bags – Placed in the sump or securely fastened to the end of a discharge pipe or hose, the bag slows down the flow of the incoming water, allowing the suspended solids to remain in the bag. Over time, the bag releases the water. Once the sediment-laden bag is de-watered, it can be picked up by a front-end loader and easily disposed of according to local enforcement agency regulations. The fabric is comprised of a heavy non-woven fabric and double chain stitched for extra security. Non-woven geo-textiles are approved by many local, state and federal agencies, including the Federal Highway Administration, U.S. Army Corps of Engineers, the Environmental Protection Agency and AASHTO.

Pump & Control System – We use heavy-duty, solids handling, air driven pumps that can be fully or partially submerged. These pumps handle debris ranging from stringy to abrasive up to 2” diameter including slurries. The pump and control systems come with a variety of valves, seats, and control panel options that will be engineered to your particular application.

Sump System – The sump is an integral part of the solids handling and separation system. They can be built in stainless steel, aluminum or concrete, with multiple compartments, weirs or screens. Sump sizes are engineered for the washing application and water treatment system. Depending on the application and location, they can be placed above ground or buried.

Robustly designed and manufactured for commercial and industrial washing applications, our heavy-duty, multi-stage, closed loop treatment systems treats the wash water so it can be used continuously without any discharge to the sewer or surroundings.

Stage 1 – Solids Settling

Wash Water Treatment System For Commercial Trucking Industry — Many companies choose to haul this water away, but a more efficient way of removing this cost is by recycling and reusing the water.

Many commercial washing operations produce a generous amount of solids so the first stage of our filtration process is the solids handling system. We help you develop site-specific solutions to eliminate as many solids as possible before running the water through to the next stage of filtration. Solutions include custom-designed sumps, basins, trenches or screening systems.

Stage 2 – Oils & Solids Separation

Truck Wash Water Treatment System — Our Commercial Truck Wash Systems are heavy-duty, multi-stage reclaim and discharge systems, engineered and manufactured for the trucking and transportation industries.

After the coarse solids settling, the water is processed through a multi-compartment stainless steel clarifier oil-water separator, which separates out smaller suspended solids, oil and water. In the first compartment, free oils float to the surface. In the second section, the stainless steel clarifying plates remove coarse amounts of oil and as much Total Suspended Solids (TSS) as possible. The angles of the non-clogging plates are 55° which allows solids to slide down the plates into the solids hopper, where they can easily be pumped out. Next, the water goes through our coalescing media which removes essentially 100% of all free and dispersed non-emulsified oils so the FOG effluent concentration can be as low as 5 ppm.

Stage 3 – Water Filtration, Odor Reduction & Polishing

After the clarifier oil-water separator, the water is pumped though several filtration steps including multi-media (sand, gravel, anthracite), blended activated carbon, polishing filter, and corona discharge ozone. These filters reduce odors and any contaminants to fewer than 10 microns in size, including emulsified oils, waxes, and other volatile organic compounds. The amount of media, carbon, ozone and water storage volume are typically customized to meet your particular application.

Sanitizing Foggers

Foggers were typically used for sanitation in food and beverage facilities. Today, however, foggers and atomizers are now being used to easily apply disinfectants and sanitizers to hospitals, schools, hotels, airplanes, cruise ships, warehouses and public transit facilities.

Using compressed air, foggers atomize ready-to-use chemical disinfecting solutions and project the fog/mist particles into the air or onto exposed surfaces.

Foggers produce dry to wet fog, and come in range of models and sizes from small hand-held models to portable systems to permanent-mount, inline systems that can project particles up to 25 feet in 8 directions! Let our engineers help you design the optimal fogging system for your facility.

Self-Contained Portable Fogger Cart

Our Portable Fogger Cart is one of our most versatile models – perfect for schools, hospitals, doctor’s offices and hotels. Powered only by a standard 120V electrical connection, this portable, self-contained system comes complete with a quiet on-board compressor, fogger body, hose and thumb-gun on a stainless steel cart. With the thumb-gun, it allows you to deliver chemical fog precisely where you need it.

The system uses compressed air to draw pre-diluted chemical solution from a pail on the cart to the fogger body which atomizes the chemical and projects it as small to medium size “damp” particles at distances up to 15 feet. Fog (mist) fills the air and saturates exposed surfaces, including hard-to-reach areas. Just plug it in and go!

Features

Stainless steel fogger body
120V air compressor
25′ twin-line air/chemical hose with activation ball valves
10 color-coded precision metering tips can refine the particle size by reducing chemical usage
Stainless steel, 4 wheel cart assembly with hose rack
Non-marking tires with stainless steel swivel casters
Stainless steel metering tip holder
Stainless steel construction ensures durability and years of outstanding performance

Portable 2-4 Way Fogger

The Portable 5 Gallon 2-4 Way Fogger is a chemical atomizer that uses compressed air and
venturi action to draw ready-to-use chemical solution from a 5 gallon pail on the cart through a
telescoping mast to the fogger body which atomizes the chemical and projects it as small to
medium size “damp” particles at distances up to 15 feet. Fog (mist) fills the air and saturates
exposed surfaces, including hard-to-reach areas.

Ball valves on two fogger bodies allow for conversion to 2-Way
fogging for narrow areas and the telescoping mast allows for
variable height adjustment up to 80 inches.
You can refine the particle size for your particular application
and manage chemical use by choosing different optional precise
metering tips.

Compact Hand-Held Fogger

The Compact Hand-Held Fogger is a chemical atomizer that uses compressed air and venturi
action to draw pre-diluted chemical solution from the attached bottle, atomize the chemical, and
project it as small to medium size “damp” particles at distances up to 15 feet.
It is easy to use! Just fill the bottle with your pre-mixed chemical/disinfectant, connect compressed
air, and press the thumb gun activator. Fog/mist will fill the air and saturate any exposed surfaces,
including hard-to-reach areas. You can refine the particle size and manage chemical use by
choosing the correct precise metering tip for your particular application.

Features

Polypropylene fogger body attached to bottle top
Lightweight wide-mouth, polyethylene quart bottle
Thumb trigger gun with easy air hose connection
10 color-coded precision metering tips

Food processing procedures are as varied as the food produced! The processing and packaging procedures for spaghetti sauce are a lot different from those of sausage, cheese and bread. And, each process produces their own unique waste streams.

That’s where we come in. We can work with your staff and custom-design a comprehensive washing and water treatment system based on your needs.

If you have to wash machinery, piping, conveyors, shelving or tanks, we can help you with pumping and heater packages featuring manual, automated and Variable Frequency Drive controls. A Variable Frequency Drive (VFD) system is one of the most cost effective units to run and maintain and allows multiple users at the same time. Different heating packages can be paired with the pumping and pressure washing systems so that you get the proper water temperature for your washing operation. Foaming, chemical injection and ozone disinfection systems can also be added to the washing systems, if required.

We can help you treat the wash water so that it can be properly discharged. If the washing process produces solids, we have a range of solutions to first separate the solids from the wastewater. After the solids are removed, we can process the water through our wastewater treatment systems.

We provide the following equipment:

VFD Controlled wash systems
Hot and Cold Water pressure washers
High efficiency heating systems
Sanitizers and Foaming Systems
Disinfection Fogging Systems
Debris & solids baskets and screens

Issue: A consulting engineering firm contacted us regarding a wash system for their client that ran numerous grocery distribution centers and warehouses on the West Coast. The FDA Food Safety Modernization Act (FSMA) rule on Sanitary Transportation of Human and Animal Food required their client to wash the interior of every truck entering their facility in order to keep foods safe from contamination during transportation.

They asked if we could help them design a hot water washing system that could handle multiple users at the same time since most of these distribution centers are very large and busy. At any point in time, multiple trucks are being unloaded and loaded as fast as possible.

Solution: In response to their request, we worked with the consulting engineers and designed a very effective sanitary washing package that would ensure compliance with the new rule by combining a high-pressure VFD-controlled pumping system with a high efficiency heating system.

For this application requiring 10 stations producing 4 GPM each simultaneously, we provided two 20 gpm @ 1700 psi pressure washing systems with VFDs and high efficiency heaters.

The VFD system offered substantial operational flexibility since the system will only utilize the power (speed of motor and pump) to match the output demands. We designed each 20 gpm system to service up to 5 users at 4 gpm each. If there is only one user on the system, however, the pump will provide only 5 gpm, and the motor/pump will only turn at 1/5” speed to meet that demand. The high efficiency heaters were integrated with the pumping systems to provide the correct temperature water to comply with the FSMA rule.

In addition to the pumping and heating systems, we also provided hoses, guns, reels and holders so their client had a complete sanitary washing package. The client liked the system so much, they ordered three more systems for other facilities!
