Ferric salt

Ferric Sulphate Instructions:

Hunan Yide Chemical Co., Ltd. Produce ferric sulphate by advanced spray drying method, our ferric sulphate has high Fe³⁺ content, high effective components, it is very easy to be dissolved in water,the insoluble substance is very low,it has strong removal capacity for turbidity, COD,BOD,SS,heavy metal and etc, has good decolorizing effect, strong flocculation capability, our ferric sulphate is better than other ordinary ferric sulfate and polymerized aluminum sulfate, polyaluminum chloride purifying agent.Our ferric sulphateis a high-tech product. The product has two kinds of liquid and solid. The appearance of liquid product is brown red, the appearance of solid product is yellow powder.All indicators of our ferric sulphate are better than national standards" of the people's Republic of China GB14591-2006 water treatment agent polyferric sulfate",and it meets the international standard of NSF and AWWA B 406-97.

Our ferric sulphate can be used safely in the purification treatment of urban drinking water,and widely used for industrial circulating water, and chemical, petroleum, mining, paper plant, power plant, printing and dyeing, brewing, steel, coal gas, electroplating industry wastewater and city life sewage water and sludge dewatering purifying water treatment, our ferric sulphatecan achieve the satisfied effect of purification water treatment for differend kinds source water from different area.

Our ferric sulphate can be used safely and effectively for use in aquaculture, by controling dissolving speed of ferric, mix and stir feed with ferric sulphate, add the mixture into water, ferric sulphateis hydrolyticed,then water pollutants fast settle, in the water bottom artificially construct rich ferric rich nutrient ecosystems, reduce the substances consuming oxygen and increase the dissolved oxygen in water, reduce the risk of aquatic products death due to hypoxia, accelerate growth of microorganism.

Characteristtics:

And our ferric sulphatehas the characteristics compared to other product

1, it is new iron salt inorganic water purified agent

2, high effective components, High Fe³⁺ content, excellent coagulation performance, alumen ustum thick,fast settle, the time is about 5-30min, with other equipment, the speed will be faster

3, It’s easy to be dissolved in water,low insoluble material, Low heavy metal content,fine water treatment effect, no iron ion is transfered into water in 10 folds dosage.

4, stable, the solution can be reserved in long time, no deposit,no degeneration,no pipe plugging.

5, Significant decolorization, deodorization, dehydration, oil removing, sterilization, removal of heavy metal ions in water, radioactive substances and carcinogens and other effects, has strong ability of removing COD, BOD.

6, Non-toxic and harmless, safe and reliable, completely solve the problem of exceeding the standard of aluminum ions caused by using aluminum salt water purifying agent, known as the green water purifying agent.

7, The application PH is 4-11, best is 6-9, after purification, the pH value of the range of variation is small, and can reduce the water hardness.

8, unique effect to micro-pollution, algae, raw water with low temperature and low turbidity.

9, the replacer for normal product, good for export.

10．According to customer's special purpose adjustment formula.

Usage and cautions

before use, you should test it in beaker to determine the dosage

1. dissolved in pond in 20-50% concentration, stirred it, then standing to till the water is brown red.

2. according the original medicine, its dosage is equal to polyaluminum chloride, is 1/3-1/4 of solid aluminum sulfate. The solution follows the concentration

3. during use, feeding the medicine by measure tank

4. watch the deposit forming state

condense phase: In short time, it form small deposit in water, the water is more cloud, the test rev in beaker is 250-300r/min in 10-30s, the time ashoule be less tham 2 min

flocculation phase: The deposi become biger nad biger, it need nor flow seppd and time(10-15min), you can see lots of deposit, there are clear interface in water

stir: first: 150r/min in 6min, then 60r/min in 4min

subside phase, The deposit is settled in water, you can use slanting tube or board( best methos is air float way), big deposite will fall into bottom, the smaal will become big, it last stage, the residual cloud will be changeless. Time: 20-30r/min in 5min, standing in 10min.

5. intensive filtration :it can increase the purified efficiency by filter structure and aids.

6. To industry sewage, the uses is similar with water making factory. To such water with high color, COD and high BOD, you can use some aids.

7. The former chemical settling equipment, you just need adding a dissolved pond.

8. Stored in dry place, avoid moisture and heat(<80°C), no break the packing, this product can be preserved in long time.

9. This product should be dissolved before use, the dissolved equipment and feeding equipment should be made from anticorrosive material.
