Lenntech - Algaecide Water Treatment Chemicals
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 present algae, but they do not remove the toxins that are released by the algae prior to ...

Lenntech - Coagulants for Water Treatment Chemicals
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 of coagulants, the pH and colloid concentrations. To adjust pH levels Ca(OH)2 is applied as co-flocculent. ...

The polymers are water-soluble and their molar weight varies between 105 and 106 g/ mol. There can be several charges on one flocculent. There are ...
-
Lenntech - Neutralizing Agents - Alkalinity Control
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.

-
Lenntech - Oxygen Scavengers for Water Treatment Chemical
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 include both volatile products, such as hydrazine (N2H4) or other organic products like carbohydrazine, ...
-
Lenntech - pH Conditioners for Water Treatment Chemicals
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 liquid. An example of bringing up the pH is the addition of natrium hydroxide, in case of an acidic liquid. The ...
-
Lenntech - Resin Cleaners for Water Treatment Chemicals
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 chloride, potassium chloride, citric acid and chlorine dioxide. Chlorine dioxide cleansing serves the removal ...
-
Lenntech - Scale Inhibitors for Water Treatment Chemicals
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 their solubility's and begin to merge, the polymers become attached. The structure for crystallisation is ...

Birm is a black granular filter material used for removal of iron and/or manganese from water in pressure or gravity systems. It contains an active insoluble catalyst to precipitate iron and/or manganese. Because the presence of iron is most common, iron removal is the usual application for Birm. Under suitable conditions, the iron and dissolved oxygen in water react on contact with the Birm filter bed and, as a result, the iron is precipitated in the ...
-
Clack - Calcite 2386
Calcite is a naturally occurring calcium carbonate media. One of the advantages of Calcite is its self-limiting property. When properly applied, it corrects pH only enough to reach a non-corrosive equilibrium. It does not overcorrect under normal conditions. Upon contact with Calcite, acidic waters slowly dissolve the calcium carbonate to raise the pH which reduces the potential leaching of copper, lead and other metals found in typical plumbing systems. ...
