Iron removal by physical chemical way - Lenntech

Iron is one of the most abundant metals of the Earth's crust. It occurs naturally in water in soluble form as the ferrous iron (bivalent iron in dissolved form Fe 2+ or Fe(OH) +) or complexed form like the ferric iron (trivalent iron: Fe 3+ or precipitated as Fe(OH) 3).The occurrence of iron in water can also have an industrial origin ; mining, iron and steel industry, metals corrosion, etc.

Solvent extraction for metal and water recovery from ...

ABSTRACT. The use of solvent extraction to recover metals and water from industrial residues is highlighted in this work. The method was applied (1) to selectively concentrate Zn from effluents generated by the zinc industry, (2) to separate Zn and Fe from spent pickling effluents produced by the hot-dip galvanizing industry, and (3) to recover Co and Ni from spent batteries.

Removing Heavy Metals From Wastewater

the next step is to add aluminum or iron salts, or organic polymers (coagulants) directly to the wastewater. These polymers attach to the metal solids particles. The small metal hydroxide particles become entangled in these polymers, causing the particle size to increase (form flocs), which promotes settling. This effect is illustrated in Figure 9.

Phosphorous removal from wastewater - Lenntech

Disadvantages are high costs for the treatment plant (big ponds and mixing devices) and sometimes a too dilute effluent. Using ferric salts there is also the risk of having some iron in the effluent, with residual coloration. The metallic ions dosage is about 1.5-2.5 ions for every phosphorus ion (on average about 10-30 g/mc of water).
