Steel & Iron Today: Siltbuster provides turnkey solution for UK’s largest steel manufacturer
Siltbuster Process Solutions (SPS), the water treatment specialist, has designed and mobilised a bespoke solution for Celsa Manufacturing UK, the largest manufacturer of steel reinforcement in the UK, to treat the wastewater it generates as part of the mechanical separation process with scrap metal.

Each year Celsa Manufacturing UK produces around 1.2 million tonnes of finished product, destined for an array of applications within the automotive, naval, construction, agriculture and mining industries.
A mechanical separation process is involved, which is applied through a vibrating deck with water passed through it to avoid any solid material sticking or plugging. The water is circulated in a closed loop system and over time it accumulates fine and particulate solid material.
SPS developed a bespoke solution, including a Lamella Clairfier HB40R, which has the built-in mechanism to be raised, eliminating the need for any water to be pumped, saving significantly on costs. The system is highly effective, removing around 80% of all suspended solids in the wastewater; all while processing 15m3 of water per hour.
This system also enables the treated water to be reused in a closed loop process, minimising water consumption and associated bills. Initially, Celsa Manufacturing UK opted to trial SPS’ modular system at its facility in Cardiff, before deciding on a permanent solution.
A project engineer at Celsa Manufacturing UK, said, “We’re passionate about making sure we work to the highest environmental standards and are constantly looking for ways to improve. We already do a lot in terms of our sustainability but wanted to see whether we could do more to implement an effective solution for our wastewater management. We’d heard about the difference SPS was making, so turned to them.”
SPS said, “This project perfectly demonstrates how valuable our ‘try before you buy’ hire options are. Our approach allowed Celsa Manufacturing UK to gauge what was possible, assess how easy it was to accommodate our kit onsite, see the difference it made, and how easy it was to operate. The project also shines a light on how effective our approach to offsite manufacturing can be. We were able to design and build the solution at our HQ in Monmouth, transport it to Celsa Manufacturing UK’s facility in Cardiff for a quick and efficient installation, keeping any operational disturbances to a minimum.”
