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.

Ultrafiltration System: Veolia Energy and University of the Sunshine Coast

RWTS were subcontracted by Veolia Energy to design and manufacture a ultrafiltration system (UF) for the University of the Sunshine Coast.

 

Client: Veolia Energy; University of the Sunshine Coast (USC)

Industry: Infrastructure – School and Universities

Systems: Ultrafiltration

 

BACKGROUND

The University of the Sunshine Coast (USC) is a leading tertiary education provider, catering to over 11,000 students on Queensland’s Sunshine Coast. USC prides themselves on their commitment of sustainability; with an active program to better manage waste, water and recycling. In an effort to minimise the use of potable water from the local council, USC engaged Veolia Energy to implement a ultrafiltration system (UF). RWTS were subcontracted to design and manufacture the water waste management system.

The water reclamation system treated water from the on-site holding dam to a potable standard. Furthermore the water was able to be used for cooling tower makeup (through evaporation) as part of the university’s air-conditioning system.

CHALLENGES

Due to site space limitations, RWTS was required to design the plant to operate effectively within a small footprint.

THE RWTS SOLUTION

Industrial Ultrafiltration System

USC Water Reclamation System - Ultrafiltration

RWTS developed an ultrafiltration system (UF), with pre-filtration to purify the raw lake water. This removed all suspended solids and microbes to ensure high quality treated water.

The design flux of the UF system, RWTS needed to design the system to be capable of treating up to 10 kL of net permeate production. Advanced UF modelling software allowed RWTS to develop the basis of the water reclamation design, that was signed off by Veolia Energy engineers.

Due to the challenges with width restrictions within the plant room, tall, hollow-fibre ultrafiltration membranes were chosen for the design. This minimised the system’s lateral footprint through stand height membranes. The membranes were procured from our oversea supplier through many years of R&D.

The waste generated from the ultrafiltration (UF) system through chemical cleans and enhanced backwashes was captured into a waste holding tank. It then underwent a staged correction process with validation prior to the release to the council sewer network. This process was approved by the contractor and local plumbing council, meeting the strict trade waste guideline release limits.

The operating system took the form of an Allen Bradley PLC with HMI screen. Functional description (FD) was written and programmed by our in-house electrical division for approval by Veolia Water. The water reclamation system build saw RWTS use quality analytical and pumping components from trusted suppliers, including as Grundfos, Burkert and IFM.

The project was completed and handed over to client Veolia Water in June 2019. Both the University of the Sunshine Coast and RWTS were pleased with the delivered outcome and the system is currently being managed by Veolia Energy site operators.

Wastewater Treatment Plant and Reverse Osmosis System: Westgold Resources

A wastewater treatment plant and brackish water reverse osmosis system for Westgold Resource’s 200-man remote camp in Western Australia.

 

Client: Westgold Resources

Industry: Mining

Systems: EcoFarmer Wastewater Treatment Plant and Brackish Water Reverse Osmosis System

 

BACKGROUND

Westgold Resources, a top 10 Australian gold producer, recently began operations on their fourth Western Australian project – Cue Gold Operations. In order to manage the wastewater of their 200-man remote accommodation village at the Big Bell Underground Mine, Westgold approached RWTS to design and manufacture a wastewater treatment system. This same site also required a water treatment system to transform he local raw (bore) water into high quality drinking water as deemed by the Australian Drinking Water Guidelines.

 

THE RWTS SOLUTION

EcoFarmer 250 Wastewater Treatment System

Westgold EcoFarmer 250

This project was an ideal candidate for the EcoFarmer 250 Wastewater Treatment Plant which utilises a Sequential Batch Reaction (SBR) process. Although this is a standard process throughout the water treatment industry, RWTS emphasised the functionality of the plant from the initial design stages. Through the seamless collaboration between our in-house engineering and electrical divisions, smart automation was integrated for enhanced productivity with less operator intervention.

How does the automation work?

The plant continually revises code as it observes the plant’s flow. When limited flow is achieved throughout the day, a standby code automatically seizes control of the plant and in peak periods the extended code will drive the plant.

In addition, Westgold Resources will reap the benefits of the EcoFarmer, that come as standard in this turnkey range, including:

 

  • Robust steel construction to withstand harsh, remote environmental conditions
  • Seamless transportability, attributed to the ISO shipping container design
  • Premium Allen Bradley HMI (interface) and PLC control system
  • Biological treatment process pre-approved by state regulatory bodies

 

Guaranteed & Certified Design

The design was accepted with process and structural certification by REPQ.

All stringent Western Australian department of health requirements where achieved, including a 20-year design life on the plant.

The structural steel shell was manufactured sandblasted, primed and painted with an International shipping coating internally. As part of our manufacturing process, spark testing was completed across the vessel to proactively identifying any potential issues with weld and coating. This ensured the integrity of the internal and external coating surface.

Brackish Water Reverse Osmosis System

Westgold Reverse Osmosis Water Treatment System

RWTS designed and manufactured a reverse osmosis potable water treatment system to meet the potable water requirements of the Westgold Big Bell remote workers’ village.

 

Built to Last

As the industry specialist in packaged water treatment systems, we decided to containerise the RO system. This allowed for ease of transportation and protection of the system from harsh rural environmental conditions.

For optimal insulation, the internal plant room was lined with 75 mm foam-filled panelling on the walls and ceiling, and air-conditioning system was integrated to ensure ideal operating temperature through the hotter and cooler months.

 

User-Centred Design and Automation for Streamlined Operation

The treated water recirculation monitoring and dosing control platform was our internal proprietary offering. This specialist feature is able to measure chlorine pH and conductivity, utilising the new range of Burkert flow fit cubes with gateway Ethernet, and display these levels in real-time on the PLC HMI plant platform.

Our internal programming and instrumentation division designed and custom-built the HMI to be single interface of all plant monitoring, streamlining plant observation and operation. This thoughtful feature allows Westgold to reduce operating costs and rapidly identify and respond to any potential issues.

As with all RWTS chemical injection systems, this Westgold system was fitted with Burkert Viton solenoids and Mazzi Venturi systems. Again, these offer fully programmable control through the HMI system, enabling the operator to take control at any time. A

The RWTS Brackish water reverse osmosis design also features flux targeting through flow metering with secondary pressure monitoring. This allows the RO system to maintain flux across the filter elements in permeate and concentrate streams through modulating v-notch ball valves. This is common on large scale membrane projects, however, in the price-driven remote camp market, it is often overlooked, and flows are set with manual tuning valves. This unfortunately is detrimental to the life of the membrane, resulting in more frequent membrane replacements and increasing the long-term operating costs of the plant.

 

Smart Technology for Flexible Monitoring & Control

RWTS uses the latest Allen Bradley HMI and PLC platform for full control of all our plants. These systems have a wireless router allowing for full remote dial-in access through site wifi. This is a must in the ever-changing water and wastewater servicing industry. It allows the plant performance and parameters to be viewed anywhere, anytime. Imagine the ease of troubleshooting over the phone with your site-based operator as you monitor the plant’s performance in real-time. That’s the RWTS difference.

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.
