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.
