Highly effective chelator for multivalent metal ions including Ca²⁺, Mg²⁺, Fe³⁺, and Cu²⁺ under alkaline and high-temperature conditions.
Excellent thermal and hydrolytic stability, maintaining performance in recirculating cooling water systems up to 80 °C.
Low dosage efficiency — provides robust scale inhibition at concentrations as low as 1–5 ppm active ingredient.
Compatible with common oxidizing biocides (e.g., chlorine, bromine) and non-oxidizing biocides used in industrial water treatment programs.
Non-toxic and readily biodegradable formulation, supporting compliance with EU Ecolabel and ISO 14040 lifecycle assessment requirements.
Cooling water treatment in HVAC and industrial heat exchange systems.
Boiler feedwater conditioning to prevent iron oxide deposition and copper corrosion.
Reverse osmosis (RO) membrane antiscalant formulations for municipal and industrial desalination plants.
Laundry and dishwashing detergent additives to enhance cleaning performance in hard water.
Oilfield scale inhibition in produced water handling and injection systems.
