1 a] Discuss the potential of cellulose-based water filters in addressing water Pollution issues What are the advantages and limitations of it.

Cellulose-based water filters :-These water filters are made from cellulose; they can remove impurities and contaminants from water and are an alternative to traditional synthetic polymer filters. On treating with required antimicrobial agents, the cellulose filters can effectively remove pathogens, and other contaminants from water, making it safer and more potable.

Construction of cellulose-based water filters

1] Cellulose Material Selection: The type of cellulose material used in the water filter will depend on the desired properties, such as strength, porosity, and chemical resistance. Common cellulose materials include paper, cotton, and wood fibers.

2] Cellulose Preparation: Materials are fragmented into small pieces, washed to remove impurities, and dried.

3] Cellulose Layer Formation: The cellulose material is made into a layer by either stacking or compacting it using heat & pressure.

4] Filter Medium Attachment: The cellulose layer is attached to a filter medium, such as a mesh or a support structure, to provide stability and increase the filter surface area.

5] Chemical Treatment: The cellulose layer may be chemically treated to modify its properties, such as increasing its hydrophilicity or adding antimicrobial agents.

6] Filter Testing: The completed filter is tested to ensure it meets the desired specifications, such as filtration efficiency & flow rate.

Properties of cellulose-based water filter

1. High Porosity: They have a highly porous structure allowing them to remove impurities and contaminants efficiently from water.
2. Biodegradability: Cellulose-based water filters are biodegradable, reducing the environmental impact compared to synthetic polymer filters.
3. Cost-effective: Cellulose-based water filters are less economical than traditional synthetic polymer filters.
4. Renewable resource: Cellulose-based water filters are made from a renewable resource; this reduces the dependency on non-renewable resources.
5. Good mechanical strength: They pose good mechanical strength, allowing them to maintain their structure and perform effectively over time.
6. Chemical resistance: Cellulose-based water filters resist most chemicals, including acids and bases, and hence can be used in various water treatment applications.
7. Large surface area: Cellulose-based water filters have a large surface area, enhancing filtration capabilities and reducing filter replacement frequency.
