The Challenge
- Brewery cooling water carried hard deposits and biological fouling
- Hard deposits on the heat exchanger cover required a chisel
- Green biological slime coated the cover and tube bundle
- Filters carried sticky deposits that resisted rinsing
- One filter was fully blocked by black and yellow biological deposits
The Solution
One HydroFLOW® Industrial trial unit was installed at the brewery, across selected cooling water circuits and assessed through three trials — a heat exchanger cover and tube bundle, a mechanical filter before and after treatment, and a heavily fouled filter followed over 30 days. Deposits softened enough to rinse away under running water, green and black biofouling disappeared, and the blocked filter returned to normal operation without any chemical or manual cleaning.
