The effect of Hubei sewage defoamer on treating sewage bubbles

Description :

　　There are many reasons for the foaming of industrial sewage, which can be divided into three stages: 1. In the commissioning stage: a large number of foam will be produced at the initial stage of activated sludge cultivation, because the activated sludge is not formed, and the surfactant in the sewage cannot be degraded (in general, it is like adding more washing powder to the water). After the increase of activated sludge, the adsorption and degradation capacity will increase, and the foam will gradually disappear.

　　2. Operation stage: the activated sludge is poisoned, and the treatment capacity is reduced due to the death of bacteria in the sludge. The reason is the same as that of foam in the commissioning stage. There are fewer bubbles generated by denitrification in the nitrification reaction, and the sewage is very turbid.

　　3. During operation, a large number of filamentous bacteria and actinomycetes grow in the water body, which is easy to produce a large number of foam. The foam is mostly yellow brown, which is difficult to treat.

　　To find out these reasons, we need to find ways to help deal with the foam problem. The organosilicon defoamer and polyether defoamer produced by Hubei Xinsihai have the characteristics of fast defoaming and long foam suppression time, and are widely used in water-based systems, sewage treatment defoamer, etc.

　　The introduction of industrial wastewater defoamers is as follows:

　　1、 Main components of industrial wastewater defoamer

　　Polysiloxane, non-ionic emulsifier dispersant

　　2、 Technical indicators of defoamer for industrial wastewater

　　Appearance: Milky white or light yellow viscous liquid

　　Viscosity: 100-1500cs

　　PH value: 6-9

　　Effective ingredients: 15% to 30%

　　3、 Scope and Characteristics of Industrial Wastewater Defoamer Application

　　This product is suitable for defoaming aqueous systems in industries such as sewage treatment and metal cleaning. It has the characteristics of fast defoaming speed, long defoaming time, non-toxic and odorless, and will not cause secondary pollution.

　　4、 Usage method of defoamer for industrial wastewater

　　Dilute this product with water or foaming solution to a uniform solution before adding it to the foaming solution, or it can be added directly.

　　The amount of addition will be determined by the customer based on specific experimental conditions. Diluted defoamers should be used up as soon as possible and should generally not be stored for more than 12 hours.

　　5、 Packaging and storage of defoamers for industrial wastewater

　　⑴ Use 50kg polyethylene drums or 200kg plastic coated iron drums, or change the packaging according to user requirements.

　　⑵ This product should be stored in a well ventilated and dry place, protected from rain and direct sunlight. It should not be mixed, transported, or stacked with strong acids, alkalis, or toxic substances.

　　⑶ Under the above conditions, this product has a storage period of 6 months from the date of production. If there is a small amount of layering phenomenon after exceeding the storage period, it can continue to be used after being mixed evenly and tested as qualified, without affecting its effectiveness.

　　⑷ This product is transported as non dangerous goods.
