What level will the wastewater defoamer be?
Acrylic acid occupies a very important position in the field of fine chemicals and is used in construction, papermaking, leather, textiles, plastic processing, daily chemicals, water treatment, metallurgy and other fields. Acrylic wastewater contains high organic matter content, complex composition, and large changes in pH value. Its main organic components include acetic acid, acrylic acid, acrolein, formaldehyde, etc. It is a high-concentration, difficult-to-treat wastewater. A large amount of foam often appears in acrylic wastewater. Excessive foam will affect the progress and efficiency of wastewater treatment. Therefore, wastewater defoaming agents need to be used to eliminate foam.
The reasons for foam generation are relatively complex. Various surfactants used in the industrial production process are the main factors for foaming. The higher the activity of the surfactant, the easier it is to produce a large amount of foam; the presence of various suspended substances, mixed into The bubbles generated by surfactants make the bubble film more stable and become difficult-to-disappear bubbles. Affected by PH value and temperature, the higher the temperature of acrylic wastewater, the greater the foaming amount, and the higher the PH value, the more difficult it is to bubble. disappear.
The generation of foam will have a certain impact on the progress of acrylic wastewater treatment, slowing down the treatment process, reducing efficiency, increasing costs, etc.; a large amount of foam will overflow the wastewater treatment system, causing the surrounding sanitary environment to be affected, and affecting the operation of wastewater treatment equipment. Normal maintenance will make cleaning difficult; excessive foam will reduce dissolved oxygen, prevent normal aeration and oxygenation, reduce the dissolved oxygen of the mixed liquid, increase SS, COD and other pollutants in external drainage, further deteriorating the water quality.
The wastewater defoaming agent has the characteristics of fast defoaming speed, long foam suppression time, low dosage, and high content; it is resistant to high temperature, acid and alkali, and can stably perform the function of defoaming and suppressing foam in a wide range of pH value and temperature range; it has Chemically inert, it will not react chemically with wastewater, will not affect the progress and effect of wastewater treatment, and will not float or stratify.
