Designed for process and drinking water applications

The new turbidity meter ITM-4DW is especially designed for process- and drinking water applications. Therefore Anderson-Negele changed the plastic components and are now using PPSU (Polyphenylensulfon).

Metrologically, the ITM-4DW is identical with the ITM-4.

The combination of transmitted light measurement and 90°- reflected light measurement allows the detection of low (fresh water) to mid (waste water) turbidities. Due to these facts, combining the two techniques, the ITM-4DW has the benefits that pollution of the optics will be almost ignored.

The ITM-4DW is not suitable for food contacting usage. For the use in drinking water applications a declaration of conformity for PPSU is available.

Quadbeam S20-IMM

We have a nice story from the mining industry for you.  Quadbeam, based in New Zealand, had a client, situated in one of the largest rock quarries, who had a problem in their sand and aggregate washing plant.  The problem was with the recycled waste water.

Following a very painful manual process, and umpteenth errors, where the waste water was being fed back to the sand washing plant, they had a Quadbeam S20 suspended solids sensor installed in a vertical section of the  pipe.  This measured, on a continuous basis, the suspended solids in the recycled water.

 

 

Quadbeam S10-IMMThe flow and suspended solids measurements were sent to a PLC, where it calculated the mass flow of the solids and adjusted the dosing pump so that the correct level of chemical addition was achieved.

 

After the flocculation process, the solids settle out in 3 large cone clarifiers.  Then, the clean recycled water is sent back to the plant.

For the last 2 years, the plant has produced consistently clear recycled water, with minimal maintenance involved.

Should this be a situation you wish to rectify, please contact us for more info on Quadbeam’s sensors.

cip system

The CIP System – Within the F&B Industry

In food manufacturing, cleaning-in-place or the CIP system is a standard component for ensuring reliable and efficient adherence to quality standards. The requirements placed on sensors, used for process control, are particularly high in the food and beverage industry.  They are tailored solutions for optimizing the CIP process, using turbidity and conductivity sensors.

What is involved?

The CIP system consists of numerous interlinked steps. Plant operators need to take into account more than just the downtime of the system. Costs also arise from the consumption of water, chemicals and energy, as well as product loss.

The sequence of the individual cleaning cycles is often still time-controlled. These fixed cleaning intervals will guarantee that the system is always cleaned properly.  However, more water, and cleaning solution and time, may be consumed than would actually be necessary for the medium being processed.

What is the solution?

The solution is to automate control of the CIP system using turbidity and conductivity sensors. The average water consumption, depending on the product, is 1.5 to 3 liters per processed liter of product.  Half of this water is used for cleaning the system.

Are there disadvantages?

A disadvantage of cleaning processes with fixed time intervals is that the maximum required cleaning duration must be used for each cleaning cycle. For example, the removal time for pasty media is considerably longer than for less viscous products. Therefore, when performing CIP cleaning after producing media with less viscosity, more water is used than is necessary.

This, however, can be remedied through automated process control using the turbidity and conductivity sensors. Water consumption at large F&B manufacturing plants can be lowered from an average of 6,500 to 2,500 liters per cleaning cycle simply by deploying an intelligent phase detection system. This will result in savings of water and wastewater costs.

In addition, shorter cleaning cycles lead to a lower consumption of acids and bases.  The use of chemicals can be precisely controlled by measuring their concentrations using the conductivity sensor, allowing their consumption to be further optimized.

What are the production-related stats?

Experience has shown that production-related losses reach 0.5% in large operations and 2.5% in small operations. It is particularly the plants with low levels of automation that experience significant losses in product.

The precise and rapid detection of water-to-product phases using the turbidity sensor lead to reductions in product losses of 5–10% in customer field projects. A CIP system usually takes 60–90 minutes. A hygienic design of the entire system is therefore an important contributor to shortening the cleaning cycles and increasing the efficiency and productivity of the process.

How can Morton Controls help?

As a specialist for sensor systems in hygienic processes, we, at Morton Controls, have sensors and process connections that are optimally designed for the demanding requirements of the F&B industry and that ensure reliable and efficient cleaning of the system.

Sensotech – Steel and Rolling Mills

In the steel production, Sensotech uses the LiquiSonic® measuring technology, which optimizes operations.  The reason, briefly, for using this technology is because of the possibility of saving chemicals, such as acids and cooling lubricants, without influencing the surface finish negatively.

We will explain the following processes in this blog: Pickling and Acid Regeneration.

To catch up with us on the other processes, namely, Cold Rolling, Electrogalvinizing, and Roller Chrome Plating, tune in for another blog coming soon.

Pickling

Pickling baths are used downstream of the hot rolling process, and also in many other fields in the metal-working industry, to remove, passivate, modify, and clean surfaces in a defined manner.

And so, pickling solutions are employed, which consist mainly of a mixture of mineral acids.  The concentration of these acids decreases during the pickling process, however the portion of distributing components, such as contaminations and carry-over increases.

The LiquiSonic® Measuring technology provides a solution for online measurements of pickling bath concentrations facilitating redosing of the required quantity of fresh acid.  This ensures a continuous optimum pickling bath quality.  Delays in time as a result of sampling and lab analyses are avoided.

These are the successful pickling bath applications where LiquiSonic® has been used:

  • Sulturic acid (H2SO4)
  • Phosphoric acid (H3FO4)
  • Hydrochloric acid (HCI)
  • Nitric acid (HNO3)
  • Hydrofluoric acid (HF)

Acid Regeneration

In this process, the acid is refreshed and removed of all contaminations, such as iron salt.  The most popular procedure used is the crystallisation for the recovery of sulturic acid.  In addition, the spray roasting or buttering-floating procedure is used, for the recovery of hydrochloric acid.

Before the used pickling acids are cleaned, they are evaporated to concentrate the acid.  The acid is then separated, and the cleaned acid is added to the pickling process.  The resulting metal oxides are used as valuable raw materials in other industry sectors.

After evaporation, the LiquiSonic® 40 system is used to determine the acid and the metal salt apart from each other.  The last part of the process is when the LiquiSonic® 30 system is used to detect the acid concentration solely, as the metal salts have been removed before.

History Around Coal Mining

We love a little bit of history, and coal mining has an interesting tale to be told.

One of the largest mining industries, mining for coal started out in the 18th century and boomed all the way to the 1950’s.  Although maybe not as huge as some other mined commodities, coal is still a valuable form of energy for open-pit extraction.

Interestingly, tunnelling into the earth to pull the coal was the initial method, but had to be stopped due to the perilous vapours that were emitted (carbon monoxide, carbon dioxide, and hydrogen sulphite) deadly to say the least.

The sensors now used in the coal mining process have helped with detecting these harmful vapours and have progressed from the mining’s canary method.

What is the Miners Canary?

If you know mining, you would have heard of this amazing story.  Very simply, miners would take a canary in a cage down with them as they descended. Canaries were known to be very sensitive to odourless vapours, such as carbon monoxide, and they would show effects of distress, rocking from side to side, before falling off their perches.

While not a very animal safe procedure, it was known to have saved many human lives.  After a time, the canary method of detection was stopped as it proved not to be as effective as they assumed it was.

In steps the Pellistor

The Pellistor was introduced as a catalytic sensor and was able to detect a very wide range of toxic vapours and flammable gases.

Due to limitations, such as malfunction when exposed to chemicals with chlorine, sulphur, halogen, and any metals containing silicon or lead; as well as high costs to maintain the pellistor, this method was withdrawn.

Infrared LED-based Gas Sensor

The more modern and more effective method is the infrared LED – based Gas Sensor.

The advantages of this method are:

  • A wider measurement range
  • A rapid response rate
  • Background gases do not affect the gas sensor, as it did with the Pellistor
  • Each gas can be detected and measured separately

UWT Level Control’s Measuring principles for level detection / level measurement

The measurement methods that UWT distinguish between are, Level Detection and Continuous Level Measurement.

Level detection is used to measure a predefined fill level, and continuous level measurement is the continuous checking of the level of the medium in a silo or a hopper.

The different measuring principles which are used in the field of level measurement technology are explained here in detail.

UWT’s Level Detection Measurement Method

Level detection is used to avoid overfilling or downtime in silos and containers.  Level limit switches are also used as spillage detectors in pipes or for the measurement of levels in interface applications.  The switching point depends on the installation position of the sensor and its configuration.  The information is analysed and transmitted via a digital signal to the control unit directly or via a fieldbus.  Other operations and alarms such as a filling stop and start, or demand signal can thus be triggered.  Level switches are used in solids, liquids or sticky media.

 

UWT’s Measurement method – continuous level measurement

Continuous level measurement,  the constant determining of the fill level, is already built into many silos, containers or process vessels, in order to implement optimum material logistics. For these measuring applications various factors such as silo and vessel geometry, sensor mounting position, the properties of the medium such as flowability, bulk density, conductivity, moisture, dust and adhesion all play a role and must be considered when selecting the right measuring principle.
