NC-312 PESA

PESA is a new, friendly to environment scale inhibitor. It doesn't contain nitrogen & phosphor, and can achieve biological degradation. It shows excellent ability to scales of CaCO3, BaSO4, SrSO4, CaSO4. Its anti-scaling effect can exceed the normally-used nitrogen-containing scale inhibitors, especially in the circumstance of high alkaline, high hardness and high pH value water systems-boiler treatment, cooling water treatment, waste water treatment, desalination of sea water, separation of membrane, etc. It is an ideal substituted green product of present scale inhibitors.

(1) Chemical Name: PESA--Polyepoxysuccinic Acid(salt)
Molecular Formula:HO(C4H2O5M2)nH,M=H,Na,K,NH4

(2) Specification:

Appearance	Colorless or pale yellow liquid
Solid content, % >=	35.0
Density (20^oC g/cm3), >=	1.28
Limit viscosity(30⁰C), dL/g	0.030-0.060
pH(10g/L water solution), >=	7.0
Biodegradability, % >=	60

(3) Use Way:
Comparison of Changes based on Dosage and Anti-scaling effect:

Dosage of Scale Inhibitor (mg/L)	5.0	7.5	10.0	12.0
Anti-scaling Effect	71%	82.5%	87.2%	85%

If mix a compound of PESA and PBTC, the effect is much better;
If PBTC: PESA =3:1. the dosage in lab for completely anti-scaling CaCO3 scale is 4 mg/L.
(The above is for reference only, not for recommendation.)
