A comparison of materials for wastewater treatment equipment.
| Pros | Cons |
|---|
| Stainless Steel | - Shorter lead time
- Doesn’t require coatings
- High durability
- Can withstand certain chemicals such as TCE, PCE and creosote
| - Can corrode due to specific chemicals in wastewater, such as strong acids and halides
|
| Carbon Steel | - High durability

| - Needs to be coated
- Can rust if coatings are not properly maintained
|
| Lay-Up Fiberglass | - Does not crack compared to molded fiberglass
- Does not require coatings
- Can withstand certain chemicals in wastewater
| - High cost
- Lower design flexibility
|
| Polypropylene | - Light weight
- Can withstand a wide variety of chemical solvents, acids and bases
| - Can degrade due to PCE and TCE, more expensive than stainless steel and carbon steel
|
| Marine Grade Aluminum | - Good for brackish water
