Battery gigafactories and EV manufacturing plants require large volumes of high-purity process water for electrode coating, cell assembly, and cooling. Lithium refining adds brine treatment complexity. These capital-intensive projects need water infrastructure that doesn't compete for investment budget.
RIEFILT delivers process water treatment for battery and automotive manufacturing through BOOT and rental models. From DI water for cell production to wastewater treatment meeting discharge limits, we provide turnkey water solutions that scale with your production ramp.
RIEFILT is a manufacturer-independent deal originator. We match the right water treatment technology to your specific requirements — not to a brand. Zero capex through BOOT, rental, or structured purchase.

Trusted by industrial clients and municipal authorities across Europe and the Mediterranean.
Our island faced a critical water shortage — 2,200 residents, peak tourist season approaching. RIEFILT structured a BOOT contract that eliminated our capex barrier. The RO system was operational within 90 days.


RIEFILT evaluated 5 manufacturers independently and recommended a solution we hadn't considered. Result: full GMP compliance and 42% lower cost per cubic meter.
