Client challenge

A UK based water management service, approached our team to replace their existing ferric sulphate injection package, which had oversized pumps causing high pulsation and vibration due to short stroke and fast motor frequency.

What we did

We conducted an engineering site survey delivered a fully automated ferric sulphate injection package housed in a modified 20-foot shipping container. The package consisted of six electric drive injection pumps controlled by variable frequency drives (VFDs), with four pumps for duty and two pumps on standby.

The Ferric Sulphate Injection Package offered a comprehensive set of features to ensure efficient and reliable operation. The package was fully automated, enabling remote monitoring, control, and operation through the onsite control system. All the necessary equipment, including chemical injection, electrical, and ancillary components, were integrated into the container for streamlined functionality.

The container itself was equipped with 12mm thick “Aqua-panels” for added chemical resistance, a non-slip floor, and a stainless-steel bund for enhanced safety. The package included three polypropylene injection pump cabinets, two for duty and one for standby, featuring Perspex sliding doors for easy access. Within each cabinet, two Milton Roy MAXROY electrically driven pumps, controlled by variable frequency drives (VFDs), were capable of injecting 407.5 liters per hour. The package control panel boasted an integrated HMI touch screen and local VFD touch pads for intuitive operation. Additionally, an emergency eye bath station was thoughtfully incorporated to prioritize safety considerations.

Results & benefits

The fully assembled package was delivered to the site, minimising hook-up and onsite work requirements. The bespoke design of the package met the client’s specifications and process parameters. The system was fully automated, allowing seamless integration into the onsite control systems for efficient and effective operation.
