Course Overview

Industries built around petrochemical products generate huge volumes of wastewaters. Due to this, most of the environmental legislation and regulations are getting stricter. Wastewater disposal and treatment methods, processes, and technologies must be interrogated and improved by every company involved in the petrochemical business to save on diminishing fresh water resources. Efficient management and recycling of wastewater are important for these industries to improve their methods and processes of disposing wastewaters.

What are the wastewater treatment technologies?

This course interrogates the methods, processes, stages, and new technology involved in the refinement of wastewater. It intends to analyse after identifying the main issues involved with wastewater. Some of the methods and processes that will be looked into include biological treatment, membrane cleaning and separation technology, coagulation, oxidation systems, flotation, and combined technologies. Ultimately, these methods intend to refine the disposed water from petrochemical industries in pursuit of making profits while adhering to the existing environmental legislation and regulations.

What do you mean by wastewater treatment plants?

WWTP (wastewater treatment plants) that are set up in oil refining industries play a vital role in treating and disposing of the wastewater. Different configurations are used together with various technologies and techniques to help refine the wastewater. It is, therefore, very important for our environment to understand these methods and techniques. The course will handle the following:

• Latest technologies that are being employed in refining wastewater
• Industry trends and developments
• Conventional and traditional water refinement plants
• Known sources of water contaminants
• WWTP effects and advantages

In this course, the participants will have the opportunity to go over the main technologies used in refining wastewater and improvements that are being made. It will provide the attendants with the knowledge and skills required to enhance their understanding of wastewater treatment.

Wastewater plays an important role in determining a petrochemical’s company minimisation techniques and cost optimisation. With careful management, the profitability of a petrochemical company can increase tremendously because of re-using resources, avoiding government and legal conflicts, and better use of resources. This course optimises all the aspects of wastewater management, including sludge management, filtration, desalting, sedimentation, skimming devices, BOD, COD, aquatic biology application on wastewater, and refinery.

Course Objectives

The main goals of this course are to enable participants with:

• Gaining extensive knowledge and skills in recovering wastewater, recycling, re-using on-site, and reducing or cutting entirely freshwater intake to fulfil environmental legislation
• Knowing the operability, reliability, and maintainability of various equipment
• Developing concrete skills in cost-effective technologies selection to aid in reducing wastewater disposal volumes and achieving zero liquid discharge (ZLD)
• Developing skills to learn the main principles, purpose, limitations of different wastewater handling technologies involved in oil refining and such industries
• Understanding the existing industry-standard targets and acceptable practices for wastewater before discharge or internal re-use
• Modifying the existing operational conditions to meet the minimum properties of incoming polluted wastewater
• Learning how to cut down the energy used and hence reduce operational costs
• Acknowledging the impacts of pollution on the currently already polluted environment
• Ability to lessen the environmental effects of wastewater
• Skills to eliminate wastewater pollutant that could have otherwise polluted fresh water
• Promote a safe environment for natural resources development such as aqua life
