Introduction
Laboratory sewage treatment equipment is designed to purify wastewater generated in laboratory settings. Effective treatment is crucial because laboratory wastewater may contain hazardous chemicals, biological contaminants, and particulates that could harm the environment. This article provides an in-depth understanding of how laboratory sewage treatment equipment operates.
Mechanisms of Laboratory Sewage Treatment Equipment
Physical Treatment
Physical treatment is often the first phase of sewage processing and involves the removal of large solids and suspended particles. Common methods include filtration, sedimentation, and flotation.
- Filtration: Laboratory wastewater passes through filters, typically made of sand or membrane, which capture particulates larger than 0.5 microns.
- Sedimentation: The wastewater is held in a sedimentation tank where gravity causes solids to settle at the bottom, facilitating their removal.
- Flotation: Air is introduced into the wastewater to create bubbles that attach to particles, causing them to float for easier extraction.
Chemical Treatment
Chemical treatment involves the addition of chemicals to induce reactions that neutralize contaminants or transform them into removable forms.
- Coagulation and Flocculation: Chemicals like alum or ferric chloride are added to aggregate small particles into larger flocs, which are then removed through sedimentation or filtration.
- pH Adjustment: Acidic or basic substances are neutralized by adjusting the pH level to between 6.5 and 8.5, using lime or sulfuric acid.
- Disinfection: Oxidants such as chlorine or ozone are used to destroy pathogenic microorganisms.
Biological Treatment
Biological treatment mimics natural processes by using microorganisms to degrade organic contaminants.
- Aerobic Treatment: Oxygen is supplied to bacterial cultures that consume organic matter, reducing biochemical oxygen demand (BOD) by 95%.
- Anaerobic Treatment: In the absence of oxygen, anaerobic bacteria convert organic pollutants into biogas, mainly methane, at efficiency levels above 80%.

Conclusion
Laboratory sewage treatment equipment utilizes a combination of physical, chemical, and biological methods to purify wastewater. By integrating new technologies, these systems provide effective solutions for removing contaminants from laboratory effluents, facilitating environmental protection and regulatory compliance.
