Do you know how to control defoamer dosage in the WWTP in order to make defoamer work best?

We know that sewage and wastewater need to be treated before it can be discharged daily. But there is a lot of bubbles in the wastewater without treatment, and these bubbles are difficult to eliminate. We must use wastewater treatment and defoamer before we can discharge. . However, how to use the defoamer and how much can be used to just eliminate all the bubbles, many people do not understand the principle, so the defoaming effect is not ideal.

Before we understand the defoamer, we must first understand its function and principle!

Anyone that can destabilize the foam can be used for defoaming. At present, there are many types of defoamers for wastewater treatment, which are mainly divided into complex system water treatment, high temperature water treatment, sewage treatment, general sewage treatment, and pulp mill water treatment. Use different defoamers depending on the nature of the water.
Below are some precautions and dosages based on these more common wastewater treatments.

1. Waste water treatment defoamer for complex systems

Silicone defoamers are generally used for wastewater treatment of complex systems. For example, the silicone defoamer invely-5023  is emulsified with various silicone greases and dispersants. It is mainly used for circuit board cleaning and various types of wastewater. Handling, etc., good compatibility, alkali resistance and long lasting defoaming. It is recommended to add an antifoaming agent before 60 ℃, the effect is the best. Pay attention to the dosage. In 10ppm, generally 10-500ppm can achieve the desired effect.waste water treatment defoamer





2.High temperature water treatment defoamer

High-temperature defoamers are generally prepared by emulsifying special high-temperature emulsifiers and can withstand high temperatures of 100-130 ° C. Has the advantages of resistance to alkali and shear. invely-6023, invely-QH are all high-temperature water treatment defoamers, which are mainly used in the fields of circuit boards, metal cleaning and various types of wastewater treatment. It can be directly added to the foaming system. It is recommended to use a metering pump for continuous dropping. The unit is generally 10-500ppm to achieve the desired effect. The actual addition amount should be tested according to the site to achieve the optimal amount.effluent defoamer





3.General waster water treatment defoamer

Defoamers for general sewage and wastewater treatment Compound emulsification preparation, suitable for storage at 5 ~ 35 ℃, has excellent instantaneous defoaming ability and long-term foam suppression effect. The dosage is also in the unit of 10ppm. It is recommended to use a metering pump for continuous dropping. Generally, the dosage of 10-500ppm can achieve the desired effect.

How do we assess antifoam efficiency ?

How do we assess antifoam efficiency ? Quality of an antifoam is given by two main characteristics : • Knockdown ability or shock effect :Meaning the speed to destroy an existing foam. • Persistence or durability : Meaning the efficiency over time.   These two parameters can be assessed by several tests. The main test is the bubbling method. A graduated column with a glass frit in the bottom is required. Foaming water is poured in the column and air at constant flowrate is introduced through the glass frit in the column. Foam is generated by the air and starts to travel up the column. At a determined level of foam, antifoam is injected. By this method several antifoaming agents can be tested. A graph reporting foam height vs time is very helpful to establish the knockdown ability and the persistence for each product. The selected antifoam is the product with the best compromise between shock effect and durability       Environmental performance   Silicone antifo...

invely-defoamers

Why Foam could be so inconvenient ? A light foam is generally not problematic in most applications however heavy foaming can often lead to various processing problems. These problems range from inaccurate readings from control and measuring equipment such as temperature, level and density controllers to poor mixing of reactants in chemical reaction vessels and products hanging in the foam, all too often leading to losses in production. Finally the presence of foaming can give a bad image of the way a process is operated in the eyes of a customer. The presence of foam in discharged effluent can cause complaints from local people and authorities even if the foam is harmless to people and the environment. How do silicone defoamers work ? Foam is a gas dispersion in a liquid or solid continuous phase. Foam iscreated by the surfactants which are at the air/liquid interface. Therefore air bubbles occur and are stabilised by the surfactants. Today, silicone antifoams are thebest solution to a...

Defoamer Test Method

Defoamer testing methods are divided into dynamic defoaming and static defoaming tests. If your foaming environment is different, the recommended test methods are different. There are three main types of foam experiments to characterize the activity of defoamers. Persistence. As we have different experimental conditions in different laboratories and the experiments used in our research to obtain results from existing literature, we will introduce these experiments below. Other methods are sometimes used depending on the particular application. 1． Ross-Miles Foam Tester   Features: Tested for strong foaming environments. This experiment is widely used for characterization        (1) Foaming of surfactant solution        (2) Research and application of foam stability in the presence of defoamer In the foaming system, the defoaming performance test was carried out by circulating bubbling by a Ros...
