Plants Benefit From Better Cooling Tower Treatment
Despite the presence of the polyphosphate corrosion inhibitor, mild steel corrosion rates in the hot return of the once-through cooling water averaged a barely acceptable 8–10 mils/yr (mpy). To reduce biological growth, the facility converted the corrosion inhibitor program to 0.5–1.0 mg/L zinc in mid-September 2014.
Cooling Tower Corrosion Inhibitors. Corrosion inhibitors are chemical compounds, organic and inorganic, that impede electrochemical reactions which cause metals to corrode. There are three classifications that define an inhibitor: reactive, precipitating, and filming inhibitors.

Scale Inhibitor Chemicals for Cooling Water Systems. Cooling water systems are subject to a variety of contaminants that can interfere with heat transfer, increase corrosion rates, restrict water flow, and cause process efficiency and production loss. Customized scale inhibitor programs are necessary for mineral scale and sludge prevention.

Accepta - The Water Treatment Product Company | Chemicals
Accepta Ltd is a British manufacturer and supplier of high quality water treatment chemicals to; water treatment service companies, chemical distributors, contractors and end users. Our manufacturing facilities have over 40 years experience blending chemicals, are ISO9001 accredited and have an on site research & development laboratory.
The usual water treatment chemicals added to open recirculating evaporative cooling systems are zinc organophosphonate (scale and corrosion inhibitor) and a biocide (to prevent algae and bacteria), so perhaps it's not surprising that they don't want you to recycle it.
- Why is polyacrylamide used in water treatment and sludge dewatering?
- Polyacrylamide and its copolymers are extensively employed in water treatment and sludge dewatering. The efficiency of flocculation is influenced by factors such as the type of flocculant used, its molecular weight, and its concentration in the water suspension.
- What is cationic polyacrylamide (CPAM) adsorption behavior?
- Cationic polyacrylamide (CPAM), a typical drilling fluid shale inhibitor can prevent the clay swelling and maintain the wellbore stable. Understanding the adsorption behavior of CPAM on montmorillonite (MMT) surfaces is of great significance in explaining the excellent performance of cationic inhibitors.
- How to overcome water absorption and swelling by clay mineral layers?
- To overcome water absorption and swelling by clay mineral layers, it is very important to develop stabilizing additives for water-based drilling fluids, where organic polymers are used as raw materials. Acrylamide copolymers, acting as flocculating agents, have the potential to separate minerals such as montmorillonite.
- Can cationic polyelectrolyte be used as a shale inhibitor?
- When using a cationic polyelectrolyte in the presence of negatively charged clays, the main driving force is electrostatic attraction 10. Several materials have been investigated as potential shale inhibitors but most of them suffer degradation at drilling which hinders their potential applications 11.
