Course description
It is essential to treat discharged waters and bring the concentrations of harmful dissolved contaminants to acceptable discharge levels. Another industrial water management concept is to reuse and recycle water within the process sections. Firstly, it makes industrial operation more economically and environmentally feasible. Secondly, it allows for treating water only to a level suitable for a certain process rather than to an acceptable discharge level. At different operating stages electrochemical treatment can be considered as a solution to remove harmful contaminants.
During the course you will understand what the electrochemical treatment is all about, how researchers and industry are developing and implementing the technology, what is needed to bring the electrochemical technology to the industrial level.
The course consists of two parts, first part is a talk containing theoretical aspects and practical experience on the electrochemical treatment of mining waters, second part is economic feasibility analysis by the means of integrating water balance modeling. You will leave the course with the ready and assessed solution to treat your water streams.
Course content
This two-days intensive course covers the following topics:
1. Introduction to electrochemical processes
a. electrocoagulation, electrooxidation, electroreduction, electro Fenton, electrodegradation, electroflotation
2. Removable contaminants
a. metals, organic matter, N-compounds, cyanide, sulfate and other anions
3. Main processes
a. operating conditions and parameters affecting the treatment
4. Post treatment technologies
a. slurry dewatering opportunities and challenges
5. Industrial applications and pilot studies
6. Economic feasibility analysis
a. water management and feasibility of mining
b. methods and examples for feasibility analysis
BEFORE the intensive course:
- Participant provides the information on the possible case where the electrochemical treatment unit may be installed at the industrial location. Specifies the contaminants and their concentration ranges in the water to be treated. If the participant is not from industry, one should think about the case where he/she wants to apply the technology and why.
- Participants will return material to the lecturer 2 weeks before the course and parts of the material will be used as a material to adjust the theoretical part and formulate practical exercises for the course
AFTER the intensive course:
- Participants will continue developing their provided case examples using provided knowledge
- A Skype-consulting (min. ~1h) will be offered individually for each participant for a case example follow-/wrap-up
Type of training
The course is combining classroom lectures, e-learning, group work and self study.
Objectives and outcome
In this course, participants will learn to:
- Familiarize themselves with current application and utilization of electrochemical treatment at industrial scale
- Identify, classify and choose contaminants that can be successfully removed to meet the limits by electrochemical methods
- Distinguish the parameters affecting the electrochemical treatment
- Develop and integrate the treatment facility containing electrochemical unit to treat mining waters
- Evaluate the suitability of electrochemical treatment of waters at various industrial locations
- Compare the electrochemical treatment with conventional technologies by the means of integrating water balance modeling
