How to Recycle Waste Water Using Plants

The video tutorial explains how active soil and wetland plants can clean dirty water, focusing on grey and black water treatment. It covers the role of microorganisms in biodegrading pollutants and describes systems like constructed wetlands and living machines. The tutorial also discusses grey water systems, emphasizing the importance of using biocompatible products and preventing root infiltration. Various configurations and practical examples are provided to illustrate these eco-friendly water treatment methods.

What role do microorganisms play in the root systems of wetland plants?

• They absorb heavy metals.

• They biodegrade pollutants.

• They provide oxygen to the water.

• They increase water temperature.

In a constructed wetland, what is the purpose of the gravel-filled basin?

• To maximize contact between water and plant roots.

• To provide nutrients to plants.

• To prevent water evaporation.

• To increase water flow speed.

What is the first step in the living machine system for treating black water?

• Water starts in a septic tank to settle solids.

• Water flows into an oxygenated tank.

• Water is exposed to sunlight.

• Water is filtered through plant roots.

How does the living machine system change the environment of the water?

• By adding chlorine.

• By pumping in oxygen.

• By heating the water.

• By adding more plants.

What is a key feature of the branch drain grey water system?

• It uses chemical treatment.

• It splits grey water into various outlet points.

• It requires a grease trap.

• It uses a series of tanks.

Why is it important to use biocompatible products in grey water systems?

• They are cheaper than other products.

• They break down into elements beneficial for plant growth.

• They are easier to find in stores.

• They increase water flow speed.

What is a potential risk if roots clog the pipes in a grey water system?

• The water will not be properly filtered.

• The system will overflow.

• The system will become less biologically active.

• Water flow will increase.
