Input wastewater quality is unstable
Cause: Input wastewater contains organic substances, chemicals, or toxic substances that can increase foam formation in the treatment tank.
Solution: Make sure that the wastewater treatment tank pre-treatment process (such as dilator, sand filter, activated carbon filter) works effectively to remove foaming substances.
Lack of oxygen in the treatment tank
Cause: Lack of oxygen in water can lead to foam formation due to ineffective bacterial activity or poor decomposition of organic matter.
Solution: Increase oxygen supply in the tank by using an oxygenation pump or increasing the air fan speed.
Obstructions in the ventilation system
Cause: Obstructions in the ventilation system may result in the inability to remove foam from the water surface.
Solution: Check and clean the ventilation pipes to ensure the system operates effectively.
Presence of foam-causing bacteria
Cause: Some types of bacteria can cause foam formation in the treatment tank.
Solution: Use chemical or microbiological treatments to control the number of foam-causing bacteria.
Inappropriate tank design or size
Cause: The treatment tank is not designed or sized large enough to effectively treat wastewater.
Solution: Review and adjust the design or size of the tank to ensure effective wastewater treatment.
In all cases, performing periodic inspections, maintenance and repairs of treatment equipment and systems is important to ensure the efficient operation of wastewater treatment tanks.
