Application
PESA is a scale and corrosion inhibitor without phosphor and nitrogen. It has good scale inhibition and dispersion for calcium carbonate, calcium sulfate, calcium fluoride and silica scale. When combined with organophosphates, the synergism effects are obvious. PESA has good biodegradability. It can be widely used in circulating cool water system in case of high alkaline, high hardness and high pH value.

Safety Information
Detailed safety information is contained in each Material Safety Data Sheet, which can be obtained from our company.
EDTMPA is nitrogenous organic polyphosphonic acid, a part of cathodic corrosion inhibitor. Its corrosion inhibition is 35 times better than that of inorganic polyphosphate. It is miscible with water, innocuous and none pollution to environment, has good chemical stability and temperature tolerance. It shows excellent scale inhibition ability under temperature 200C. It can dissociate into 8 positive-negative ions, thus can chelate with many metal ions to form polymer reticulation complex, to destroy the normal crystallization of calcium scale. EDTMPS shows better antiscale effects to calcium sulfate and barium.
1. ATMP can be used in thermal power plant, recirculated cooling water of oil refinery, and recycle waterflood system of oilfield..
2. ATMP can decrease scale formation and inhibit corrosion of metal equipment and pipeline.
3. ATMP can be used as chelating agent in woven and dyeing industries and as metal surface treatment agent.
ATMP is usually used together with other organophosphoric acid, polycarboxylic acid and salt to build all organic alkaline water treatment agent. ATMP can be used in many different circulating cool water system. The recommended dosage is 5-20mg/L. As corrosion inhibitor, the recommended dosage is 20-80mg/L.
HEDP is an organophosphoric acid corrosion inhibitor It can chelate with Fe Cu and Zn ions to form stable chelating compounds It can dissolve the oxidized materials on these metals surfaces HEDP shows excellent scale and corrosion inhibition effects under temperatures of 250C HEDP has good chemical stability under high pH values is hard to hydrolyze and is hard to decompose under ordinary light and heat conditions Its acidalkali and chlo rine oxidation tolerance are better than that of other organophosphoric acids salt HEDP can react with metal ions in the water system to form a hexaelement chelating complex with calcium ions in particular Therefore HEDP has good antiscale and visible threshold effects When built together with other water treatment chemicals it shows good synergistic effects

Water Softener Salt Tablets: Water softener salt tablets, 25 kg or 10 kg bags of tablet salt, work via a process known as 'Ion exchange'. Resin beads within the water softeners help to create soft water from hard water. As a result, the hard water goes over the resin beads to help remove magnesium and calcium minerals.
