“How is industrial wastewater treated before being discharged?”

1. In groups, discuss the solution to the above question Bab 13/5 Nota8 B05-193a Chemistry Green
through a brainstorming session. http://kubupublication.com.my/Kimia/Tingkatan5/Nota8.pdf
2. Scan the QR code to obtain the Chemistry
Green Technology Module (pages 29 – 32) for an activity Technology Module
on wastewater treatment using electrolysis. https://bit.ly/kpkt5n8
3. Conduct this activity under the supervision of your teacher.
4. Present your findings in class in a Gallery Walk activity.

• Landfill Leachate Treatment Method by using the electrolysis Effluent is waste
principle, which is also known as electrocoagulation process, is a in the liquid form
Green Technology approach that can be used to treat wastewater, discharged into the
including industrial wastewater. drainage system or
water source.
• Carbon or copper electrodes are used while wastewater is the
electrolyte in the electrocoagulation process. Pollutants will form Bab 13/5 Video49 B05-193bcWastewater
flocs and can be isolated from water and then removed as sludge. http://kubupublication.com.my/Kimia/Tingkatan5/Video49.html

• After proper treatment, sludge can be used as fertilisers for the Treatment
agricultural sector or disposed of by appropriate methods depending https://bit.ly/
on the composition of the materials contained in sludge.

• Wastewater that has been treated can be reused for crop irrigation, or
discharged as effluent.

• Steps in wastewater treatment are briefly shown in Figure 5.26.

The Importance of Green Technology in Life

• Green Technology has trailblazed a new chapter in the field of technology with more
environmentally friendly approaches without neglecting the original purpose of technology.
This development contributes to the economic sector of the country through the creation of new
industrial sectors and employment opportunities based on Green Technology. The importance
of Green Technology in life can be seen in Figure 5.27.

• Environmental pollution can be reduced and management of resources will be more efficient
and well organised. How can you as a pupil integrate Green Technology in your daily life?

There are various wastes in your school that include food wastes and plastic bottles. Electricity

consumption is also high due to the lengthy use of fans and lights.
1. Plan a competition in class.
2. Each group is required to submit a product or proposal to address the above issues using the

Green Technology approach.
3. Invite the teachers to judge the product from each group.

1. What is the meaning of Green Technology?
2. Why is there a need to treat the leachate in solid waste disposal process?
3. List the Green Technology used in wastewater management.
4. How can Green Technology mitigate the greenhouse effect?
