The Advantages of Automation for Wastewater Treatment Plants

Automative predictive maintenance technology allows us to program your plant machines and equipment with sensors that allow you to effectively monitor any issues. Our programmed sensors track critical operational information; like internal pressure, water flow rate and temperature; to alert your operation managers of any damages, wear or impending equipment failure.

Increase Efficiency

Automated wastewater treatment systems are poised to make treatment plants more efficient than ever before. The combination of the remotely accessible equipment and minute-to-minute data visualizations allows for boosted treatment capacity — like remote troubleshooting and maintenance, which will save your plant hours in downtime.

 

Another attractive advantage of programming and automating controls that gather data in wastewater treatment facilities is that your company has the chance to reduce the usage of chemical additives. From monitoring the depth of the sludge bed to fine-tuning the pH of water holding tanks, greater data availability can help reduce expenses and even prolong the life of critical equipment — like basins, filters and chemical pumps — by slowing down or eliminating corrosion.

Similarly, our automated systems can also reduce the amount of water that is lost during the treatment process, saving your companies plants and your operation additional resources.

Constant Access to Data and Ongoing Sampling

In wastewater treatment and other industry processes, “grab sampling” has long been the process operations rely on to achieve data visibility. The problem with this method is that it requires ongoing labour and it only provides a snapshot of conditions when the sample was taken. Programming and automating the sampling process is a more precise way to identify patterns and trends, engage in more meaningful analysis, and make timelier decisions before small problems become bigger ones.

Furthermore automating data isn’t just about collecting more data, it is also about obtaining more qualified data. Our clients can engage remotely online to monitor in real-time, saving the hassle of sending samples to a lab for analysis. Not only will you save time with our automation but also you are guaranteed that the samples will not change in composition between the time the sample is gathered and when it arrives to the lab for processing.

What are the advantages of automation for wastewater treatment plants?

Programming and automation in recent times has become a necessity in wastewater treatment plant solutions. This service is one of the most critical industrial-level activities today when wastewater and water management is concerned. Here are some of the ways this technology is making the process more efficient and cost-effective.

Lower Energy Costs

Not surprisingly, energy use is the single biggest expense for wastewater treatment plants. Programming and automating infrastructure provides one way to reduce energy expenditures associated with a number of critical water treatment processes.

For example the blowers located in holding basins, which keep the water purified. Blowers can account for up to 50% of a water treatment plant’s total energy consumption. Programming and automation can improve cost effectiveness with reducing energy consumption through data collection. Instead of operating the blowers constantly, at a fixed speed, plants can use information about effluent levels in holding basins to apply air and remove solids only when it’s necessary to do so. This reduces energy costs, helps maintain a steady flow and reduces wear and tear on equipment.

Similarly, our automated systems can also reduce the amount of water that is lost during the treatment process, saving your companies plants and your operation additional resources.

Wastewater Treatment System: Balter Brewery

Balter Brewery approached RWTS with the need for an upgraded trade wastewater treatment system to handle their steadily increasing daily load.

The Issue | An overrun wastewater treatment system

The wastewater treatment system procured originally was designed adequately for the daily load of 3000 litres and was sufficient for the brewery’s early beginnings. However, due to Balter’s growing popularity, production has both increased and improved. This lead to daily site hydraulic loads of the wastewater treatment solution exceeding its designed capacity.

As such, the system design was essentially overrun, creating operational and reliability issues. This resulted in a system that could not perform correctly and meet the hydraulic demands the site was experiencing. In addition, we saw the potential to add significant value and functionality to the brewery’s waste treatment system design.

The RWTS Solution

We proposed, designed and developed an enhanced system to not only ensure reliable operation, but to allow the comfortable treatment of 20,000 litres per day (that’s a lot of beer!).

By integrating advanced wastewater treatment technology, the new design allows for remote monitoring of the entire system operation, minimising the need for operator intervention and unnecessary maintenance. In short – more insight, less work. The HMI will provide a flow log and pH log each time the system discharges to trade waste on a daily basis. Data from the system can be stored for a minimum 30-day log and potentially up to 60 days.

If your brewery is looking for a wastewater treatment solution that provides detailed insight in real time but requires minimal operator intervention, we would love to discuss a tailored solution with you.

Wastewater Biological Treatment and Ultrafiltration System

RWTS custom-built a wastewater treatment back-end biological polishing unit designed within an ultrafiltration system. The system treated Class C effluent to that of a true Class A final release standard. 

The system was complete with front end glass media filtration, before water was filtered through the ultrafiltration membrane elements.

The membranes of choice for the wastewater biological treatment were the RWTS UF-PVDF-1060 hollow fibre filter housings with an effective filtration area of 78 m2. The membranes were configured to an outside-inside, with air sparge backwashing, forward flush, top and bottom backflush, and an independent enhanced backflush EBF cycle also coded within the PLC. The PVDF fibre allows for greater tensile strength when filters are exhausted and feed pressures rise, due to uncontrolled front end treatment. The ability to rejuvenate the fibre element is second to none; with an aggressive alkali and acid cleaning process the filters will bounce back yielding their intended designed flux. Other membranes constructed of improved PVC and simple PVC cannot withstand such harsh environments and are susceptible to fibre breakage, resulting in cross contamination of raw and treated water streams.

The system was constructed on a purpose-built, 316 stainless steel frame. All pumps utilised for filtration, backwash and chemical injection were Grundfos pumps to ensure durability and reliability.  The feed pumps being controlled by VSD which allowed for variable flow treatment through the day. Process control pneumatic valves used in this system were air torque actuators with separate limit switches and Ritork cast wafer valves were integrated. Burkert instruments were chosen by the client. Additionally, control automation was completed through an Allen Bradly 800 Series PLC and Panel view plus 7 – 9 inch HMI screen with a Ewon modem for remote telemetry access.

The membranes have been installed with individual isolation valves on all 3 streams allowing for the disconnection and replacement of the individual membranes units without isolating the system. Clear tubing has additionally been added to allow the operator to view the turbid backwash reject water exiting the system.

All in all, RWTS has encompassed the very best in equipment supply and design to deliver a high-performance, durable system which will see many years of trouble-free filtering.

The equipment was installed and successfully commissioned onsite by the RWTS electrical and programming division.
