Click on pictures for larger pictures without numbering.
Equipment Area adjacent to
Six Truck Wash Bays
This system is set up utilizing existing facilities and equipment then augmenting these with new standard equipment and our own in-house site specific custom designed equipment. The entire system is designed and installed by Industrial Equipment. Though the following describes this particular system, we design and install many other systems. We would design a system for you to meet your specific needs.
For this system, trucks are washed out in the six (1) wash bays utilizing our custom designed mud blaster for the major bulk materials, then cleaning with hot high pressure water provided by our custom designed hot high pressure washer pumping modules. The (2) mud blaster and pressure washer pumping modules are located adjacent to the wash bays in an equipment area. See below for close up of this area.
This equipment area also contains an (3)Above Ground Cone Bottom Three Tank Oil-Water-Solids Separator. The water from the final tank is used to feed the mud blaster as well as the sewer discharge treatment system. These cone tanks have an automatic decant system to remove sludge daily. The separator is aerated to start microbe activity. This pretreatment greatly reduces the amount of solids and oils that get into the main treatment equipment. This reduces the maintenance needed for the system.
The washing equipment for this site consists of two components and is designed to provide an efficient wash environment and to be very dependable.
The first component of washing consists of (2) hot high pressure washer pumping modules which provide 5 gpm @ 2300 psi and have a remote control, time delay shutdown, electronic ignition, and two hose retractor poles.
The second component of washing consists of a (1)"mud blaster". A" mud blaster" provides much more flow than a pressure washer(20 gpm @ 600 psi). This flow makes it possible to clean much further away and quickly removes bulk materials like mud, trash, and grass. The mud blaster for this system is made so that it uses water straight from the final tank of the (4)Above Ground Cone Bottom Three Tank Oil-Water-Solids Separator. This means that for this system bulk removal uses recycled water.
See below for close up of wash bay details.
(1) Two High Pressure Washer Hose Retractor Poles one in back and one in front of Wash Bay.
(2) One Mud Blaster Pole in front of each Wash Bay.
(3) Six Wash Bays
(4) Seven Splash Guard Curtains protecting the Wash Bays from over spraying.
Six Truck Wash Bays
with Splash Curtains and Hose Retractor Poles
The (3) six wash bays are setup with hot, high pressure washer and mud blaster hoses installed on retractor poles.
The actual hot high pressure washer pumping modules and mud blaster are located in the equipment area adjacent to the wash pads (See above picture). Both the hot high pressure washer and mud blaster were custom designed to fit the specific needs of this site.
The hot high pressure washer hoses are installed on two hose retractor poles; one (1) pole in back and one (1) pole in front of each wash bay.
There is another hose retractor (2) pole attached to the front pole of each wash bay that is dedicated to the mud blaster hose.
Each wash bay is also protected from over spraying into adjacent bays by (4) Splash Guard Curtains installed on either side of each wash bay.
In this style of system, there are no filters to plug or that would need replacing. The entire waste water treatment system uses multiple technologies to clean the water before it is discharged. These technologies can include oil skimming, bioremediation, separation/settling, and pH control (if needed). These technologies remove most of the suspended solids and hydrocarbons in the waste stream.
This system is considered a sewer discharge system. However, if conditions warrant it, we could use this system as the first stage of a recycle system.
The wash water treatment equipment for this system uses a variety of technologies to treat water before it is discharged. This system is similar to the example conceptual design described on our Consultation webpage for Site Specific Designs.
The run off from a wash pad adjacent to the Equipment Room flows into a sump pit. A belt oil skimmer is used in the sump pit to remove all free oil in the system before it is emulsified by any pumps.
Then the waste water flows into the (2)Above Ground Cone Bottom Three Tank Oil-Water-Solids Separator, which settles out most of the solids from the waste stream. These solids can then be easily flushed out of the cone tanks and allowed to dry prior to disposal.
The waste water is then processed by a waste water treatment system, which creates the proper environment to allow continuously introduced microbes to consume emulsified oils and control BOD and COD before final discharge into sewer. This system uses a (1)Watermaze Bioremediation system to treat the waste water.

Detail of Solids Collection Trough
The Washpad is slightly sloped to direct run off towards entrance of Solids Collection Trough.
As waste water flows down the trough solids settle out for easy removal.
Belt Oil Skimmer
and Sludge Dewatering Dual Bag Filter
A (1) Belt Oil Skimmer removes free floating oil from the waste stream before it is emulsified by any pumps. The main components of a Belt Oil Skimmer are two pulleys with a belt that is constantly rotating through the sludge. This system uses a Polyurethane Belt. Some systems use Stainless Steel Belts. Typical oil pick up rate runs about 4 gallons/hr.
A (2) Sludge Dewatering Dual Bag Filter basically makes it easy to remove the sludge settled out in the bottom of the cone tanks of an Above Ground Cone Bottom Multiple Tank Oil-Water-Solids Separator. This is how the Sludge Dewatering Dual Bag Filter is used in this system.
You can also use a Sludge Dewatering Dual Bag Filter to assist in removing sludge from the
(3) Solids Collection Trough if you have an attachment to your pressure washer called a Pit Cleaner (or Sludge Sucker) . To use a Sludge Dewatering Dual Bag Filter for this you would use it in the Pit Cleaner system in lieu of the Sludge Cart (Sludge Cart is shown in the Pit Cleaner system). The Sludge Dewatering Dual Bag Filter holds a much greater volume of sludge than a Sludge Cart and also provides filtering. A Sludge Cart does not provide filtering.
(1)Watermaze PM-1000 Bioremediation System uses microbes to consume hydrocarbons in the waste stream. This significantly reduces the amount of hazardous waste generated in a water treatment system.
The PM-1000 provides a
fully automated, environmentally
friendly and low-cost way
to manage standing wash water
found in collection pits, tanks or
sump drains.
It is designed to be integrated
into most wash-water treatment
systems utilizing aeration
and automatic
injection of a highly
effective microbial
agent (such as BioStax
1800) for eliminating
oils, greases and other
hydrocarbons and organics
typically found in collection
pits or sump drains.
BioStax 1800 has proven to be very effective
in controlling odor and converting
oils, greases, and hydrocarbons
into harmless carbon dioxide and water.
The aeration further enhances the effectiveness
of the microbes as well as providing odor control.
This pretreatment greatly reduces the amount of solids and oils that get into the recycle system. It also reduces the maintenance needed for the system and gives a better quality wash water.
The waste water is then pumped into the recycle system.
The recycle equipment for this site is a (2) Watermaze CLB Bioremediation wash water recycling system with (3) Harmsco Hurricane Micron Filtration. The entire recycling system uses multiple technologies to clean the water before it is either reused by the pressure washers or "discharged". These technologies include bioremediation in a cone tank, ozone generation, pH control (if needed), chemical oxidation injection, and micron polish filtration. These technologies remove hydrocarbons, and oxidize biologic material, and remove suspended solids down to approximately 5 microns in the waste stream. The processed water is then repressurized back to the pressure washer or "discharged" as needed.
Excess water can come from a leak, someone using a hose, or a spill on the washpad. In addition, the wash water can be kept "fresher" by adding some fresh water on a regular basis.
If your site does not have access to sewer, we recommend using an evaporator to reduce your hauling needs. The evaporator reduces the volume of water needed to haul by about 95%. The cost per gallon to evaporate this water would be approximately 8%-9% of what hauling would cost.
The evaporator is also an effective means for reducing the waste generated by an aqueous parts cabinet washer(s) or wash sinks if you have any.
This system uses a (2)Washpad covered by a (1) Three Post Metal Canopy to provide an area to wash motorcycles.
The Washpad is installed adjacent to a (3) Waste Water Equipment Room.
The objective of our design solutions is to create a washing environment that keeps the maintenance of the water treatment equipment to a minimum. In addition, we believe in keeping all of the solids above ground so that a pumping company is not needed on a regular basis. A well designed wash area will incorporate several key designs into the site. This will extend filter life and reduce any hazardous waste that would be produced by the treatment system.
The (1)Washpad is slightly sloped to direct run off towards entrance of (2) Solids Collection Trough.
As waste water flows down the trough solids settle out for easy removal.
(3) Waste Water Equipment is installed in an Equipment room adjacent to the (1)Washpad. The equipment is installed directly against the wall behind the (2) Solids Collection Trough.
Solids Collection Trough, Sump Pit,
and Sludge Dewatering Dual Bag Filter
A (1)Washpad is slightly sloped to direct run off towards the (2) entrance of a Solids Collection Trough.
As waste water flows down the (3) Solids Collection Trough, solids settle out for easy removal.
The washpad and trough design effectively removes a majority of the solids from the waste stream before it even enters the treatment equipment. Please refer to the conceptual design discussed on our Consultation web pages for more details on the washpad design.
The washpad will significantly reduce the maintenance and replacement of media or filters required for the treatment system.
A (5) Sludge Dewatering Dual Bag Filter removes the sludge settled out in the bottom of the cone tank of the Watermaze CLP Filtration System used in this water treatment system.
The processed water is then repressurized back to the pressure washer or discharged if excess water from rain or another source overfills the system. The CLP system included in this system automatically backflushes itself to reduce the amount of manual maintenance needed by the equipment. The automatic backflush requires compressed air, which is provided by a small compressor we attached to the system.
Any excess water from rain or fresh water rinse needs to be discharged from the system. This water can be evaporated, stored in a tank for later use, or discharged to sewer.This system discharges excess water to a (3)Watermaze HBG Evaporator System.
The revolutionary CLP includes two models that are fully
automated. The CLP’s exclusive Automatic Maintenance
Control system uses a digital sequencer to automatically
backwash filters, dispense sludge and monitor and adjust
pH and oxidizer levels resulting in cleaner water, reduced
odor problems, lower maintenance costs and a smoother
operation, to say nothing of the happier, more productive
workers.
Three manually operated systems offer an economical
alternative with flow rates of up to 30 GPM.
All CLP models are preplumbed
and self-contained on an all-steel platform protected
by an epoxy powder coat finish.
Any excess water from rain or fresh water rinse needs to be discharged from the system. This water can be evaporated, stored in a tank for later use, or discharged to sewer.
This system discharges excess water to a(1)Watermaze HBG Evaporator System - a Conventional Wastewater
Evaporator with High-Efficiency
Combustion Chamber.
The HBG evaporators process
wastewater at rates of 8, 15, and 30 gallons
per hour.
All the HBG Evaporator units are made of heavy duty
steel, insulated and double lined
for energy efficiency and safety.
The HBG models feature a unique
combustion chamber design, which
uses advanced heat reflective material
to reflect the heat directly onto the
underside of the evaporation tank floor
for super-efficient energy usage.
A variety of redundant systems insure
the safety of the operator. For instance:
A high-limit thermo-couple turns
off the unit before the tank can be damaged
by scorching (includes a remote mounted,
audio-visual thermal alarm)
A stainless steel float system provides
high-low water level protection
by shutting off the unit when the wastewater
level rises or lowers excessively
A third float provides redundant or
backup protection.
