Chemical-Free Water Treatment (SBR™) is a fully automatic online water treatment system that continuously cleans cooling tower water without a single chemical dose. Scale precipitates out in a reaction chamber instead of depositing on your heat exchangers.
The same cooling tower, treated two different ways — chemical dosing still leaves scale and biofouling behind; SBR™ doesn't.
Instead of dosing chemicals to keep hardness minerals in solution, SBR™ continuously draws a side-stream of cooling tower water through a reaction chamber where scale-forming minerals are precipitated out and removed. The treated water returns to the tower with dramatically reduced scaling and biological fouling potential — with no moving parts and no chemical storage or handling on site.
Treat cooling tower water without any chemicals.
Reduce bleed-off quantity from your cooling tower.
Increase cycles of concentration by 2–3x.
Reduce sewage treatment plant costs downstream.
Adopt environment-friendly water treatment.
By running at higher cycles of concentration and cutting blowdown volume, SBR™ reduces freshwater intake, effluent (STP) treatment costs, energy use, and the labour that used to go into managing a chemical dosing program. All precipitation of salts occurs in the reaction chamber — leaving no scale in your system's heat exchangers, and giving you control over corrosion potential thanks to the low aggression of treated water.
Save up to 60% on operational costs, with 100% chemical savings and 5–15% lower energy costs.
30–100% decrease in water usage, 10–50% lower labour costs, and up to $10/m³ reduction in STP cost.
Water reuse for irrigation, 2–3x cycles of concentration, and scale/biological/corrosion control — precipitation happens in the reaction chamber, so no scale reaches your heat exchangers, and treated water's low aggression keeps corrosion in check.
No chemical dosing, storage, or handling anywhere in the system.
Higher cycles of concentration mean less makeup water and bleed-off.
Typical payback on an SBR™ install is under two years.
No chemical discharge, no compliance burden, no handling risk.
SBR™ is installed across commercial buildings, industrial cooling towers, and power plants — and is especially valued during prolonged shutdowns, when chemical dosing programs are hardest to maintain and Legionella risk is highest.
