Treatment of oily wastewater features:
Flocculation technology has been widely used in the treatment of oil-bearing wastewater because of its strong adaptability, the ability to remove emulsified oil and dissolved oil, and some complex polymer organic matter that is difficult to be biodegraded. The commonly used flocculants are mainly inorganic flocculant, organic flocculant and compound flocculant.
Low molecular weight inorganic flocculants such as polyaluminum chloride and polyferric sulfate have been widely used for their good treatment effect, low price, low dosage and high efficiency.

Industrial wastewater treatment:
1, printing and dyeing wastewater treatment, instead of traditional low molecule by iron and aluminum salt coagulants, relative to the traditional large dosage of coagulant, the coagulation efficiency is low, such as aluminum ions residue is easy to cause the secondary pollution, the characteristics of polymeric ferric sulfate dosing quantity at about 150 parts per million, the small dosage, high removal rate of COD and chromaticity, suitable for ph conditions as follows: 8.0. [2]
2, electroplating sewage treatment, can be used as coagulant and collateral-breaking agent. The complex is mainly copper - ammonia complex, its property is stable, pH=11, it is difficult to directly precipitate with alkali, polyaluminum and other coagulants. It can also be used as recycled water.
3, papermaking wastewater treatment, instead of polyaluminum chloride, aluminum sulfate, used as coagulant, can also be used as papermaking sludge dehydration, in papermaking wastewater treatment white water recovery process can not be used polyferric sulfate (containing strong cation polymer), can only use polyaluminum chloride.

Waterworks water treatment:
1, the toxic harm of aluminum, aluminum is a slow growing poison, with water into the human body will accumulate in brain cells and other tissues, long-term drinking aluminum coagulant treatment of tap water will cause alzheimer's disease, cardiovascular disease, osteoporosis, renal dysfunction and other chronic diseases. According to the China Committee of the International Alzheimer's Association, there are more than 24 million Alzheimer's patients worldwide, of which more than 7 million are in China, and the number of new patients is increasing at the rate of 300,000 every year. The permitted content of aluminium in drinking water standards of western developed countries is 0.05 mg/l. The amount of aluminium in Tap water in China is several times higher.
2, water supply pipeline corrosion problem, due to the water pipeline electrochemical corrosion problem has not been solved, users tap water turbidity, chroma, iron content, bacteria and other water quality index values and greatly increased, resulting in further deterioration of water quality. Due to corrosion, the inner wall of the water supply metal pipe corrodes, and the resistance of water flow increases continuously, and the power consumption of water supply increases year by year, resulting in a huge power loss. After water supply pipeline corrosion perforation, a large number of tap water leakage away, at the same time, the service life of water supply pipeline is greatly shortened.

【Notes】Due to different properties of raw water, site debugging or beaker test should be carried out according to different situations to obtain suitable use conditions and dosage to achieve better treatment effect.

1. Before use, put the product into the alum solution pool according to a certain concentration (10-30%), inject tap water and stir to make it hydrolyze fully, stand until it becomes a red-brown liquid, and then dilute with water to the desired concentration and add coagulation. Water plant can be directly added into 2-5%, industrial wastewater treatment directly added into 5-10%;
2. The dosage can be determined according to the nature of raw water through production debugging or beaker experiment according to the formation of alum flower appropriate amount. The dosage of other drugs originally used in the water plant can be used as a reference. If the original use is liquid products, can be calculated according to the concentration of the corresponding agent. Approximately according to the weight ratio of 1:3;
3. When in use, pump the prepared liquid medicine into the metering tank, add the liquid medicine and coagulate with the raw water through metering;
4. Under normal circumstances, the medicine is prepared on the same day and used on the same day;

5. Pay attention to the hydraulic conditions of the three stages of coagulation and the formation of alum flowers;
(1) Coagulation stage: it is the process in which the liquid medicine is injected into the coagulation tank and the raw water coagulate rapidly to form a microscopic alum flower in a very short time. At this time, the water becomes more turbid, which requires the water flow to produce intense turbulence. Beaker experiment should be fast (250-300 RPM) stirring 10-30s, generally not more than 2min;
(2) Flocculation stage: it is the process of growth and thickening of alum flowers, which requires proper turbulence degree and sufficient residence time (10-15min). At the later stage, a large number of alum flowers can be observed to gather and slowly sink, forming a clear surface layer. For beaker test, stir at 150 RPM for about 6 minutes, and then stir at 60 RPM for about 4 minutes until suspension.
(3) Settlement stage: It was conducted in the sedimentation pond, flocculating settling process required flow is slow, inclined tube (plate) commonly used to improve the efficiency of sedimentation pond (had better use air flotation separation of floc), a large number of bulky alum flowers inclined tube (plate) wall block and deposit on the bottom, the upper water as clear water, the rest of the small particle size and density of small alum flowers side slowly down, side to continue to collide with each other ", The residual turbidity remained unchanged until the late stage. Beaker test should be 20-30 RPM slow stirring for 5 minutes, and then settle for 10 minutes to measure residual turbidity.

6, strengthen filtration, mainly reasonable selection of filter layer structure and filter aid, in order to improve the removal rate of the filter, it is an important measure to improve water quality;
7, this product is applied to environmental protection, industrial wastewater treatment, the use method and water plant is roughly the same, high chroma, high COD, BOD raw water treatment, supplemented by additives effect is very good;
8, the use of chemical coagulation method of the enterprise, the original equipment need not make a big transformation, just add alum pool can use the product;
9. The product must be kept in a dry, moisture-proof, heat-proof place (< 80℃, do not damage the package, the product can be stored for a long time);
10, the product must be dissolved before use, dissolution equipment and dosing facilities should use corrosion resistant materials.

When used, generally the liquid polymeric ferric sulfate with 10%- 50% aqueous solution (in the higher turbidity of the source water can be directly added), solid polymeric ferric sulfate with 10%- 30% aqueous solution, and then according to the specific situation of the good solution according to the suitable conditions and dosage of input, after full stirring can be suitable for coagulation effect.

Dosage can be determined according to the different turbidity of raw water, suitable dosage, general turbidity (turbidity in 100-500mg/L) water, each thousand tons of use of this product 30-50kg, non-drinking water high turbidity industrial sewage can be appropriate dosage.

For industrial wastewater treatment, grade I polyferric sulfate is diluted to 1-2 times aqueous solution. When the concentration of source water is high and the amount of treated water is large, it can be directly added. Then, according to the results of laboratory simulation test, the water can be clarified after full agitation, coagulation and sedimentation by adding suitable technological conditions and dosage.

Water purification plant can be diluted 2-5 times before adding. Dosage can be determined according to the nature of raw water through production debugging or beaker experiment according to the formation of alum flower appropriate amount, the water plant can be used as a reference of other drug dosage, under the same conditions, the product and solid polyaluminum chloride dosage is roughly equivalent, is 1/2 to 1/3 of the solid aluminum sulfate dosage. If the original use is liquid products, according to the concentration of the corresponding agent calculation, roughly according to the weight ratio of 1:3.

Practice has proved that ordinary polyferric sulfate is difficult to achieve the expected purpose in most cases. In general, it is necessary to conduct dosage form selection test according to the use medium and use place to determine the appropriate amount of dosage, and then carry out industrial dynamic test to determine the suitable dosage point and dosage.
