BATEA Exercise:

Scenario: A small-scale textile factory in a developing country is looking to upgrade its wastewater treatment system. The existing system is inefficient and contributes to water pollution.

Task: Using the BATEA principle, analyze the following three options for the factory's wastewater treatment upgrade:

  • Option 1: A simple, traditional filtration system (low cost, low effectiveness)
  • Option 2: A modern biological treatment system (higher cost, highly effective)
  • Option 3: A hybrid system combining filtration and biological treatment (medium cost, moderately effective)

Consider:

  • Effectiveness: How well each option reduces pollutants from wastewater
  • Cost: The financial burden of implementing each option for the factory
  • Availability: Whether the technology is readily available in the region

Based on your analysis, recommend the most suitable option for the factory, explaining your reasoning based on BATEA principles.

Exercice Correction

Here's a possible analysis and recommendation:

**Option 1 (Traditional Filtration):**

  • **Effectiveness:** Low. While it removes some solids, it's ineffective for removing chemical pollutants common in textile wastewater.
  • **Cost:** Low. This is the cheapest option, but it may not be cost-effective in the long run due to its limited effectiveness.
  • **Availability:** Likely readily available.

**Option 2 (Modern Biological Treatment):**

  • **Effectiveness:** High. This system can break down a wide range of pollutants, leading to significantly cleaner wastewater.
  • **Cost:** High. This option is the most expensive upfront, potentially a financial challenge for a small factory.
  • **Availability:** May be less accessible in developing countries, requiring specialized expertise and equipment.

**Option 3 (Hybrid System):**

  • **Effectiveness:** Moderate. Combines the benefits of filtration for solids removal with biological treatment for chemical pollutants.
  • **Cost:** Medium. This option strikes a balance between effectiveness and cost.
  • **Availability:** Potentially easier to source than the advanced biological system but may still be more complex than traditional filtration.

**Recommendation:**

Considering the BATEA principle, **Option 3 (Hybrid System)** appears to be the most suitable for this factory. It provides a good balance of effectiveness, cost, and availability. While it may be slightly more expensive than traditional filtration, it offers a significantly higher level of pollutant removal, making it more environmentally responsible and likely to comply with regulations. Additionally, this option may be more accessible than a fully modern biological treatment system, especially in a developing country context.
