Treatment with ferrous sulfate, ferrous sulfate water price Shu Shu manufacturers use water ferrous sulfate Features

Sanhe seven water ferrous sulfate 280 yuan / ton, 950 yuan ferrous sulfate monohydrate / ton [Introduction] Sanhe Sanhe ferrous sulfate, ferrous sulfate, ferric sulfate (II) is an inorganic compound of formula FeSO4, the most commonly used it is blue-green heptahydrate. Sanhe ferrous sulfate monohydrate is a white powder, containing water of crystallization is light green crystals, crystal commonly known as "copperas", dissolved in water solution as a light green. Sanhe Sanhe brand of ferrous sulfate crystallization their different water content can be divided into: a water Sanhe Sanhe ferrous sulfate and ferrous sulfate heptahydrate. Sanhe ferrous sulfate by water and moisture into a seven water; use is divided into agricultural, industrial, pharmaceutical, food-grade and so on. Sanhe seven water ferrous sulfate pigment used in the manufacture of iron and iron-based catalyst and water purification, sewage treatment; ferrous sulfate monohydrate Sanhe mainly do agricultural fertilizers and feed additives, in particular on ferrous sulfate monohydrate in Sanhe the effect of agriculture to be significantly higher than the seven water ferrous sulfate. Sanhe Sanhe factory specializing in the production of ferrous sulfate industrial water treatment agent, with seven water Sanhe agricultural fertilizer and feed grade ferrous sulfate monohydrate ,, using dilute sulfuric acid and ferrous scrap processing, precipitation of iron sulfate crystals. The main production of ferrous sulfate monohydrate Sanhe FeS04? 7H2O, ferrous sulfate heptahydrate Sanhe FeS04? 7H2O. Use can be divided into industrial grade Sanhe ferrous sulfate, ferrous sulfate Sanhe agricultural grade, garden fertilizer grade special-recipe type. [State] Sanhe ferrous sulfate nature sky blue or green monoclinic crystal series, odorless, taste salty, astringent; irritating. 14.8 degrees under state: density under 1.8988g / cm3.15 degree Status: density of 1.897g / cm3 Melting point 64 ℃, soluble in water, insoluble in alcohol series. Dry air stroke into a white powder. Corrosive, wet air oxidation that is rapidly deteriorate into a yellow-brown basic ferric sulfate. 300 ℃ when anhydrous, continue to heat were decomposed into ferric oxide, water, sulfur dioxide, sulfur trioxide gas. [Sanhe ferrous sulfate] Item Unit Specifications Sanhe industry indicators index FeS04? 7H2O% ≥85 ≥93.7% ≤0.002 ≤0.0015 heavy metal content of water insoluble matter% ≤1.0 ≤1.0 arsenic As% ≤0.0005 ≤0.0003 free acid H2SO4% ≤2.0 ≤2.0 [Sanhe ferrous sulfate, ferrous sulfate Uses] Sanhe on sewage treatment has wide range of uses, primarily as a flocculant, a reducing agent, the precipitation agent. 1, as a flocculant: Sanhe most extensive use of ferrous sulfate is used as flocculant as flocculant has the following advantages: settlement rate, large granular sludge, sludge volume is small and dense, in addition to good color effects (very suitable for dyeing, washing and other textile wastewater treatment), non-toxic and beneficial organisms grow (ideal for use in subsequent biochemical treatment process sewage system), without changing the original technology, low price, as a flocculant, Sanhe sulfuric acid Ferrous polymerization can replace aluminum, basic aluminum chloride, polymeric iron, aluminum sulfate, ferric chloride, etc. 2, as a precipitating agent: can and sulfides, phosphates precipitate formed, thereby removing the sulfur compounds, phosphate ions, sulfur-containing waste water treatment dyeing Sanhe ferrous sulfate. Sanhe ferrous sulfate decolorizing ability to remove metal ions, to oil, to the scales, sterilization effect is good, bleaching and dyeing wastewater and removal of the CDO, ferrite electroplating wastewater, such as co-precipitation effect. 3, as a reducing agent: Sanhe ferrous sulfate is a strong reducing agent, can be reduced to a moisture content of hexavalent chromium electroplating wastewater into trivalent chromium, instead of expensive sodium sulfite, sodium bisulfite, sulfur dioxide, etc. . The advantage is not toxic and carcinogenic stimuli produce chlorine body (mainly two hydrogen sulfide), low prices. 4, as a biological nutrients: mainly as a biochemical system in iron nutrition of microorganisms, microbial activity to improve the system, so as to ensure and enhance the efficiency and stability of the system. 5, as the landscaping purposes: the soil pH adjustment, prompting the formation of chlorophyll (also known as iron fertilizer), can prevent the flowers caused due to iron deficiency (yellowing disease). Hi acidic cycads flowers especially indispensable element. Ferrous sulfate is widely used as a purifying agent Sanhe, gas purification agents, disinfectants, deodorants, feed additives, food additives, mordant, herbicides, and the system for inks and pigments. Medical use as a blood tonic, contained iron pigment hemoglobin synthesis in vivo, for the most common iron deficiency anemia. Micronutrient fertilizer is used in agriculture, control wheat smut, apples, pears have blisters scab, fruit rot was able to remove the moss and lichens on tree trunk. [Sanhe ferrous sulfate in agricultural and horticultural use the above method] First, the performance characteristics: adjust the soil pH, prompting the formation of chlorophyll (also known as iron fertilizer), can prevent the flowers caused due to iron deficiency (yellowing disease). Hi acidic cycads flowers especially indispensable element. Second, usage and dosage and control object (1) Usage: ①, 10 克 watered 4 to 5 pounds, foliar spray. ②, normal growing season, 1-2 times per month. ③, disease prevention phase, 10 to 15 days, for 2 to 3 times. (2) Dosage: 10 g watered 7-9 pounds, watering basin, about 20 days time. (3) prevention and treatment of diseases and principle: Indications (yellowing disease). Mainly: on young leaves, before the beginning of leaf yellowing of leaves on both sides, the central focus or brown spots appear tip; long, the leaves fall off. Principle: adjust the soil pH, acidity hi beneficial flowers grow normally. (4) for plants: flowers and all kinds of hi acidic, such as: cycads, azaleas, camellias, Milan, spider plants, asparagus, Prynne, poinsettia, five needle pine, jasmine, ferns, palms and various class bonsai pots of flowers . Because the soil more than a "north south acid base," the origin of the south transplanting landscape plants use more time to adjust Sanhe ferrous sulfate north. (5) Note: Do not overuse, if because of excessive use and the emergence of the phenomenon of burn seedlings, please use the following method ↓ ①, if spraying: Leaves with water in front and back again several times more spray. ②, if IRRIGATING: filling with water several times more than the basin. Third, in some areas of acid soils hi watering flowers like alum fertilizer application. Such vitriol brewing method is: water 20 to 25 kg of a 1.5 kg, Sanhe ferrous sulfate 250 to 300 grams together into the cylinder, cover, on the sun exposure for about a month, until their maturity fermentation supernatant diluted watered several times its layers can be used. Using this fertilizer watering flowers hi acidic soil, such as camellias, azaleas, smiling and other good results. Because the material prepared to spend alum fertilizer, the soil is acidic reaction, pH value between 5.8 to 6.7 on average. Regular application of fertilizer can basin remained acidic alum, prompting hi acidic soil robust growth of flowers, dark green leaves and bright. Another method is to cook alum fertilizer maturity of fertilizer in fertilizer plus 1 g per 500 g of ferrous sulfate Serve Sanhe, together with dilution water use.
