Q. What is USP?
A. It is the Ultrasonic Scale Preventer.
It harnesses the dynamic energy of strong ultrasound to prevent or remove scales which have been a huge and consistent troublemaker in the operation and management of various industrial facilities unless otherwise treated properly. The Morko USP puts ultrasound into the equipment, device, and machine to be treated utilizing a generator (amplifier), a transducer (magnetostrictive), and electric wiring.
Q. Does the unit operate continuously or can it be shut off?
A. Yes, this unit can operate continuously (24 hours per day), but it can be shut off at any time, if necessary.
Q. How competitive is your USP vs. chemical treatment?
A. We believe that our USP treatment is superior to conventional chemical treatments for scale problems in three aspects as follows:
1. No extra costs for either purchasing or disposal of chemicals and additives
2. No concern about serious erosion and corrosion expected from chemical usages
3. Environmentally more friendly when compared to chemical treatments
Q. Besides pipes and heat exchangers, is your technology used in other applications?
A. Yes, there are many other applications. For example, utilizing powerful ultrasonic vibration, the quality of paint, tire, wine, dye, and others can be greatly improved (upgraded) by homogenizing effect of materials in liquid phase. There are also some successful USP applications for repelling birds at fruit farming land, fish and shells at a power plant, and possibly other vermin. Another successful application was to clean truck body frames for Hyundai Motor Cars. In the past, water-filled tanks for body frame cleaning tanks were heated to 122°F to clean these frames. With our USP equipment, this preheating process for a large volume of water is not necessary any longer, enabling the company to save energy costs substantially.
Q. What kind of warranty do you offer?
A. We provide fully one-year warranty.
Q. What is the delivery time for the equipment?
A. Normally, the delivery takes three months from ordered date. Depending on our stocking situation, one month delivery may be possible.
Q. Are there any harmful effects to adjacent equipment, personnel?
A. As far as we know, the USP is not harmful to adjacent equipment and personnel. It generates some pulsing sound, but this noise is not so loud as it harms our hearing organs.
Q. In the wastewater treatment field, struvite seems to be most prevalent where anaerobic digestion is employed?
A. Struvite (MAP) is a nuisance mineral encounted most commonly where anaerobic digestion facilities are in operation. This mineral is particularly rapidly precipitated in dehydrating process (centrifuging, condensing, filtering, etc.), causing clogging pipe line.
Q. Do you know of struvite issues in other wastewater applications?
A. We believe almost all of municipal WWPTs have struvite problems due to their precipitation and clogging pipes. However, struvite problems appear not to be so serious in industrial wastewater treatment environments. Rather, other minerals that have long plagued engineers and managers seem to be calcite, siderite, anhydrite (gypsum), and siloxanes. Regardless of the mineral species, our USP can be applied to a wide variety of situations to remove scales (or fouling) and to effectively prevent their precipitation within pipe line of various facilities associated with HVAC.
Q. How are transducers attached to the pipe…welded?
A. Transducers should be welded to the outside wall of a pipe. They are installed preferentially at elbow parts where fluid flows are very turbulent within the pipeline.

Q. How are transducers attached to the pipe…welded?
A. Transducers should be welded to the outside wall of a pipe. They are installed preferentially at elbow parts where fluid flows are very turbulent within the pipeline.
Q. How many transducers would be needed on a heat exchanger?
A. It varies depending on the type and size of a heat exchanger.
1. U-tube type: ideally four transducers (at least two) on a tube sheet (note: only one tube sheet is present in this type.)
2. Fixed shell and tube type: ideally four transducers (at least two) on each tube sheet (note: two tube sheets present in this type.)
Q. Can the control panel and transducers be located outside in freezing conditions or must they be mounted indoors?
A. It is believed that the equipment will work properly at the air temperatures ranging from -20℃ to 50℃. This device has been installed at many outside facilities and operated without any problems up to now.
Q. Can the control panel and transducers be located in explosive locations or must you provide an explosion-proof enclosure?
A. Technically the control panel and transducers can be installed at almost any locations. For explosive locations, however, our explosion-proof model (USP-300-UL) encased with a special device is strongly recommended. Our USP-300-UL model earned explosion-proof certificates from UL.
Q. For pipe applications, would you ever install two transducers across from one another, or is that primarily for heat exchangers?
A. For pipe applications, we’ve never installed them across from each other. According to Morko engineers, they work best when they are installed at a normal angle from each other. For heat exchanger, however, we installed four transducers on tube sheets across from each other.
Q. Is struvite more likely in sludge piping feeding a belt press, centrifuge, etc. or in the filtrate and centrate pipes from these devices?
A. Struvite scales tend to form in either situation. However, it is believed that the struvite problem is more serious in the filtrate and centrate pipes than in the sludge feeding pipes. This is because the liquid that flows after passing through the filtrating process include very high concentrations of phosphate.
Q. Is the power supply single phase?
A. Yes, it is a single phase and its voltage is 220V.
Q. Is it possible to mount our transducers on or near valves and pumps to help remove struvite?
A. Yes it is possible, but the spots to be mounted should be NEAR the valves, rather than NOT just right ON the valves.
A. It varies depending on the type and size of a heat exchanger.
1. U-tube type: ideally four transducers (at least two) on a tube sheet (note: only one tube sheet is present in this type.)

A. Yes it is possible, but the spots to be mounted should be NEAR the valves, rather than NOT just right ON the valves.
Q. Do transducers wear out?
A. Yes, but it takes very long time to wear out. We believe that they can be used at least five years without replacement.
Q. How much power(w) do the transducers use?
A. The power per transducer is in the range between 100W and 200W.
Q. Once the transducer is attached to the pipe for example and the control panel is mounted near the transducer along with the power cable, what is involved to make it operate?
A. The generator (control panel) is connected to transducers with a 30m long electric wire. The control panel has its own power switch and its power cable should be plugged into any ordinary 220V socket.
Q. What is the ultrasound frequency range of USP?
A. Technically, it ranges from 10 kHz to 24 kHz.
Q. Can the frequency be adjusted or is it meant to stay within a range?
A. Yes, it is adjustable but only within the limited range 10 kHz to 24 kHz.
Q. Can your USP be used on all types of heat exchangers such as shell & tube, plate & frame, etc?
A. Yes, but there are some exceptions such as aluminum brazed heat exchangers and gasket plate heat exchangers. This is because aluminum is often very susceptible to ultrasonic waves. The gaskets between plates tend to absorb ultrasonic waves.
Q. Where is/are the transducers located on a heat exchanger?
A. They are sitting outside surface of heat exchanger tube sheets. (see the picture below; locations are marked by red arrows)
A. Yes, but it takes very long time to wear out. We believe that they can be used at least five years without replacement.
