For cooling water with hardness 300–600 mg/L CaCO₃, recommend dosing 40–80 mg/L of LK-319. Actual dosing rates should be precisely adjusted based on site water chemistry and system cyclical loads.

4. Can lk-319 be dosed continuously and is it compatible with other biocide treatments?

Yes, LK-319 is designed for continuous feed in dosing pumps and is highly compatible with most non-cationic oxidizing and non-oxidizing biocides. It is stable under typical operational pH/temperature regimes.

5. What installation and operational standards should be followed with scale and corrosion inhibitor for cooling tower deployment?

Comply with ANSI/AWWA B600 and ISO 14001 during installation. Use corrosion-resistant dosing pumps and ensure regular system water monitoring per EN 1212.

6. What are typical field-measured results for lk-319 compared to other inhibitors?

Typical corrosion inhibition in field use: ≥99.2% (vs. 96-98% for most legacy products); scale inhibition: ≥99.0% (industry average: 97–98.7%). Service life exceeds 15,000 operational hours, supported by both lab and real-plant monitoring.

7. Is lk-319 safe for use in zero-discharge and sensitive environmental sites?

Absolutely. LK-319 contains no phosphates or NTA, is readily biodegradable, and meets discharge requirements for zero/low-phosphorus mandates. Suitable for both ZLD (Zero Liquid Discharge) and eco-sensitive plant locations.
