SUSPENDED SOLID SENSORS – GET BETTER CONTROL

For better control over your suspended solids, we recommend Quadbeam’s S-range of suspended solid sensors, both for hygienic and immersion capabilities.

In addition, you will realise cost savings, a reduction in losses, and higher concentration control, in a repeated and accurate manner.

 

THE MAIN FEATURES OF THE S-RANGE SUSPENDED SOLID SENSORS

  1. Because of the 4-beam self-compensating sensor, drifting is eliminated and therefore electronics aging and contamination is done away with
  2. You have one-piece piece casing and therefore no leakage in the lenses – completely glass-free
  3. These sensors are reliable, repeatable and accurate

Quadbeam offers a number of models in their suspended solid sensors, namely:

Under Hygienic –

– S10-3HY

– S10HT-3HY

– S10-2HY

  • From DAF plants, final outlet of effluent measurement
  • Dairy plant loss control

 

 

MORE ON THE T30

 

There are two emitters and two detectors, which are set at 90 degrees to each other.  As they pulse in sequence, two detector currents are produced, one from the detector at 90 degrees to the emitter (scattered light) and one from the detector opposite the emitter (attenuation). A Ratio-metric four beam signal processing compensates for changes in optical properties of emitters and detectors due to ageing and surface coating.

 

A standard built-in cleaner is available with the T30 submersible turbidity sensor from Quadbeam.  The recommended cleaning method is with high pressure air with an optional biocide included. To protect the sensor fingers from impact, stainless steel support rods are designed to lift and protect the sensor fingers in rugged applications.

waste water

Quadbeam has the perfect solutions for the Wastewater Industry

What if we could offer you self-compensating process control sensors, which gave you much improved control and reliability?  Your current single and dual beam turbidity sensors are great, but once you have tried Quadbeam’s answer, you will never look back.  Quadbeam offers us a range of applications, focused on accuracy and better control of your processes.

In the Waste Water Industry, these are vital elements.

 

Quadbeam promotes these key benefits:

  • Improved process control
  • Reduced costs
  • Long-lasting components
  • Highly repeatable, reliable and accurate
  • Controls de-sludging process

The various Applications where their waste water products can be utilised are:

  • Polymer dosing control for DAF plants
  • MLSS measurement
  • Monitoring influent and overflow streams
  • Return/Waste Activated Sludge
  • Final water release monitoring.
  • Clarifiers

Let’s take a step back and ponder on what wastewater treatment is all about and why it’s so important to have accurate systems in place.

quadbeam waste water

The stages of wastewater treatment:

  • Influent screening to remove plastic and other indigestible solids
  • Separating heavier particles from the liquid in the primary sedimentation tank – heavier particles sink to the bottom of the tank (the sludge blanket) while the supernatant (surface overflow effluent) rises to top
  • The sludge must be emptied at regular intervals to make room for more de-sludging process
  • A sludge pump can prove useless – either it allows overflow or will pump out water with the sludge
  • Knowing the level of the sludge blanket is paramount for controlling the de-sludging process

This is where Quadbeam comes in …

  • One can control the de-sludging process by:
  • Either using Quadbeam’s MXD73, MXD75 or MSSD20 transmitters with Series 20 sensors
  • Using two of these – reason being that with a single sensor installation, you run the risk of too much sludge being discharged and the sludge blanket will be lost
  • Using two Series 20 sensors, they rally with one another to ensure the blanket is always maintained
  • Further factors which affect the sludge blanket formation
  • Settling rate
  • Influent rate
  • Wastewater source and components
  • Downstream solids concentration requirements
  • Blanket height vs solids concentration correlation

Other areas which must be taken into account are:

  • Whether the sludge blanket is to be used for thickening (generally underflow solids concentration can be 0,5% to 1,5%) or
  • Or, to be used for digesting (2,0% to 5,0% solids)

These factors are relevant for the primary clarifier process.

As the influent to a primary clarifier is raw or screened wastewater mixed with recycled effluents from the plant, it is important to check.  Check that your influent flows are not extreme and causing disruptions in the sludge blanket accumulation.

Quadbeam 4 beam

Four-beam technology from Quadbeam

As the engineer or plant manager, you need to ensure that you constantly reduce costs, improve efficiency and deliver excellent quality to your customers.

Quadbeam Technologies offers us the Four-Beam Technology where they can ensure your operations perform at the best they can.

 

What is the Four-Beam Technology all about?

The Four-Beam alternating light principal design is there to improve the reliability of your measurement of all optical suspended solids and turbidity instruments.

Very often most sensors won’t pick up what has caused an error if that cause is related to dirt or contamination on the sensor surface, or even because of ageing electronics.

This is because they are using a single-beam which is very limiting.  Quadbeam’s Four-Beam Technology ensures that all angles are taken into account throughout the process.

There is no drift with four beam sensors, whereas a single beam will drift a significant amount to make it an issue.

quadbeam 4-beam

So, how does Quadbeam differ from the other four-beam suppliers?

Quadbeam have not invented the four-beam process, but have most definitely improved upon it.  They are able to improve both reliability and performance, and isn’t that what you want?

 

Simple, but effective

With most things, having more than one is always better.  Essentially, Quadbeam Technologies have designed the alternating light principal, giving you two lights, and therefore two detectors.  They can compensate for the variations in both light intensity and detector sensitivity.  They do this via their ratio metric signalling system.  Two light sources are switched on and off alternatively and work with the two detectors simultaneously.

If you work in an industry where accuracy is paramount, get in touch with us at Morton Controls, and we will set you up with Quadbeam’s Four-Beam Technology.

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.

 

 

 

 


 

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
