Mexel 432 - Treatment Proces

by Ovivo (Formerly Eimco Water Technologies)     based in Salt Lake City, UTAH (USA)

The Mexel 432 process offers a “green” alternative to traditional methods for the treatment and protection of cooling water circuits against fouling, corrosion, scaling, mud and mussel colonization. The Mexel 432 cooling water circuit treatment is more efficient and less expensive than conventional techniques that use oxidants (Cl2 or ...

Coagulants for Water Treatment Chemicals

by Lenntech Water Treatment     based in Delft, NETHERLANDS

When referring to coagulants, positive ions with high valence are preferred. Generally aluminium and iron are applied, aluminium as Al2(SO4)3- (aluin) and iron as either FeCl3 or Fe2(SO4)3-. One can also apply the relatively cheap form FeSO4, on condition that it will be oxidised to Fe3+ during aeration. Coagulation is very dependent on the doses ...

Solids Polymer Flocculants for Water Treatment Chemicals

by Lenntech Water Treatment     based in Delft, NETHERLANDS

To promote the formation of flocs in water that contains suspended solids polymer flocculants (polyelectrolytes) are applied to promote bonds formation between particles. These polymers have a very specific effect, dependent upon their charges, their molar weight and their molecular degree of ramification. The polymers are water-soluble and their ...

Scale Inhibitors for Water Treatment Chemicals

by Lenntech Water Treatment     based in Delft, NETHERLANDS

Scale is the precipitate that forms on surfaces in contact with water as a result of the precipitation of normally soluble solids that become insoluble as temperature increases. Some examples of scale are calcium carbonate, calcium sulphate, and calcium silicate. Scale inhibitors are surface-active negatively charged polymers. As minerals exceed ...

pH Conditioners for Water Treatment Chemicals

by Lenntech Water Treatment     based in Delft, NETHERLANDS

Municipal water is often pH-adjusted, in order to prevent corrosion from pipes and to prevent dissolution of lead into water supplies. During water treatment pH adjustments may also be required. The pH is brought up or down through addition of basics or acids. An example of lowering the pH is the addition of hydrogen chloride, in case of a basic ...

Algaecides for Water Treatment Chemicals

by Lenntech Water Treatment     based in Delft, NETHERLANDS

Algaecides are chemicals that kill algae and blue or green algae, when they are added to water. Examples are copper sulphate, iron salts, rosin amine salts and benzalkonium chloride. Algaecides are effective against algae, but are not very usable for algal blooms for environmental reasons. The problem with most algaecides is that they kill all ...

Resin Cleaners for Water Treatment Chemicals

by Lenntech Water Treatment     based in Delft, NETHERLANDS

Ion exchange resins need to be regenerated after application, after that, they can be reused. But every time the ion exchangers are used serious fouling takes place. The contaminants that enter the resins will not be removed through regeneration; therefore resins need cleaning with certain chemicals. Chemicals that are used are for instance sodium ...

Oxygen Scavengers for Water Treatment Chemicals

by Lenntech Water Treatment     based in Delft, NETHERLANDS

Oxygen scavenging means preventing oxygen from introducing oxidation reactions. Most of the naturally occurring organics have a slightly negative charge. Due to that they can absorb oxygen molecules, because these carry a slightly positive charge, to prevent oxidation reactions from taking place in water and other liquids. Oxygen scavengers ...

Neutralizing Agents - Alkalinity Control

by Lenntech Water Treatment     based in Delft, NETHERLANDS

In order to neutralize acids and basics we use either sodium hydroxide solution (NaOH), calcium carbonate, or lime suspension (Ca(OH)2) to increase pH levels. We use diluted sulphuric acid (H2SO4) or diluted hydrochloric acid (HCl) to decline pH levels. The dose of neutralizing agents depends upon the pH of the water in a reaction basin. ...

Oxidants for Water Treatment Chemicals

by Lenntech Water Treatment     based in Delft, NETHERLANDS

Chemical oxidation processes use (chemical) oxidants to reduce COD/BOD levels, and to remove both organic and oxidisable inorganic components. The processes can completely oxidise organic materials to carbon dioxide and water, although it is often not necessary to operate the processes to this level of treatment.
