Oily sewage treatment equipment

Oily sewage treatment equipment plays a vital role in addressing the challenges associated with oil-contaminated water. This advanced technology offers an efficient and sustainable solution for the treatment and purification of oily wastewater, ensuring environmental compliance and promoting water resource conservation.
1. Purpose and Functionality of oily sewage treatment equipment:
Oily sewage treatment equipment is specifically designed to remove oil and hydrocarbon contaminants from wastewater generated in various industrial processes. It combines multiple treatment techniques to effectively separate and treat oil, grease, and suspended solids present in the wastewater, resulting in clean and reusable water.
2. Key Components of oily sewage treatment equipment:
The equipment typically consists of the following components:
   - Oil-Water Separators: Utilizes gravity separation or coalescence techniques to separate oil from water.
   - Dissolved Air Flotation (DAF) Unit: Facilitates the removal of fine suspended solids and oil droplets through flotation and skimming processes.
   - Biological Treatment Unit: Utilizes biological agents or microbial consortia to degrade organic pollutants present in the wastewater.
   - Filtration System: Removes remaining suspended solids and impurities through various filtration media.
   - Advanced Oxidation Processes (AOP): Employed for the degradation of persistent organic pollutants, if required.
3. Working Principle of oily sewage treatment equipment:
The oily sewage treatment equipment operates through a series of well-coordinated processes:
   - Pre-Treatment: Large debris and solid particles are removed using screens and settling tanks.
   - Oil-Water Separation: The oil-water separator separates oil by exploiting the difference in density between oil and water.
   - Dissolved Air Flotation (DAF): Fine solids, oil droplets, and dispersed substances are removed via flotation and skimming processes.
   - Biological Treatment: Microorganisms degrade organic pollutants through biological processes, converting them into harmless substances.
   - Filtration: Remaining suspended solids and impurities are removed by passing the water through various filtration media.
   - Disinfection (Optional): Advanced oxidation or disinfection techniques ensure the complete elimination of harmful microorganisms.
4. Advantages of oily sewage treatment equipment:
   a. Efficient Oil Removal: The equipment delivers high removal efficiency, effectively treating oil-contaminated water.
   b. Environmental Compliance: It helps industries meet stringent environmental regulations and discharge standards.
   c. Water Reuse: Treated water can be reused for non-potable purposes, reducing freshwater consumption.
   d. Cost-Effective: By reducing the need for off-site disposal or water purchase, it offers cost savings in the long run.
   e. Compact Design: The equipment is designed to occupy minimum space, making it suitable for installation even in limited areas.
   f. Customization: It can be tailored to specific industrial requirements and wastewater characteristics.
