Iron suplhate is usually used for the purification of industrial wastewater (treatment plants) by physico-chemical processes, coagulation and flocculation. The solids and the liquid are mechanically separated. Eliminating the packaging with toxic content. The presence of bivalent iron (Fe2 ) help the chromats (heavy metals) to become soluble or colours to be transformed into sludge. At the same time, iron salt is used for the removal of phosphates. Phosphate precipitated from iron sulphate as a low soluble iron phosphates. It is used for treatment of raw water in the supply of drinking water and industrial process water. For the production of biogas. As a reagent, for example in the production of pigments and other compounds of iron, including use as a catalyst. To lower the content of chromium VI in cement for the recultivation of soil. Laboratory chemical. As an additive in adhesives and sealants. In the machine building industry, for the neutralization of the sulphuric acid in the production of electrolytes. As agrochemical. To treat iron chlorosis in practice using ferrous sulfate, also known as green stone. It imports soil to a depth of 20-25 cm below the crown of the trees. The doses in fruit trees are 200-300 grams per tree. In order to have the effect of the soil and the submission of the green stone, it should be followed by abundant irrigation. Otherwise the iron will once again enter the hardly to absorb forms.
 
Faster iron deficiency be corrected through the combined introduction of ferrous sulphate – soil and leaf. For foliar it is necessary to make a 0.15% solution of ferric sulfate (15 g per 10 litres of water). In 2 to 3 treatments of leafy vegetation in permanent crops the problem with iron chlorosis is resolved completely. Iron deficiency can be corrected through the introduction of cogeneration and ferrous sulphate – soil and leaf. For foliar it is necessary to make a 1% solution of copper sulfate. Spraying make in the cooler times of the day – morning after lifting of the dew or late in the day. The night spraying has better effect, because spraying the solution on the leaves slowly dries up and digested a larger quantity.
 
For effectively combating chlorosis in all cultures (irrigation solution: 150 – 200 g dissolve in 10 l of water) In order to make, the fruits of apples and pears beautiful and well colored, must be filled with iron. To this end, 2 g of ferrous sulphate (green vitriol) dissolved in 1 liter of water, then spray the fruit with this solution. This procedure is done when the fruits have reached the ¼ of its normal size. When such processing fruit increase in size as the iron sulphate causes growth. It also gets unusual and bright colouring of the fruit of the Apple. Good time for submission is in the fall or in the spring. Against eggs of mites and insects on fruit trees over 5 years of age can be used as out of vegetation 6-7% ferrous sulphate solution. Anti-infection chlorosis in the vines pruning wounds in autumn or early spring are smeared with 30 percent solution from green stone. Green stone can also be used against slugs, sprayed with a 10% solution. It is used against slugs in greenhouses, as dusk sprayed aluminium, paths and around greenhouses. Use baits and bits of chopped carrots and potatoes, to which is added a green stone in the amount of 1:20. To remove the mosses and lichens in fruit trees after cleaning the bark from the invaders are treated with a solution of Ferrous sulphate /green vitriol/ in concentration – 1 tsp to 1 liter of water.
