General Purpose Water Purifying Plants

Water purification machines

General-purpose water plants are designed to purify water with high levels of contaminants like fluorides, iron, and suspended solids. This treated water can then be used for a wide range of activities, such as cleaning, washing, and irrigation. While it’s not suitable for drinking or cooking without further purification, this process offers an efficient solution for managing water quality.

Water Purification Process

The purification process involves several stages to ensure the removal of impurities and contaminants. The key steps include:

  1. Pre-Chlorination: Adding a small amount of chlorine to disinfect the water and control bacteria growth.
  2. Flocculation: Adding flocculants that bind particles together, aiding in their removal during the filtration process.
  3. Sand Filtration: Passing water through layers of sand to trap larger particles and sediments.
  4. Carbon Filtration: Using activated carbon filters to remove residual chlorine, organic compounds, and odors.
  5. Brim Filters: Employing brim filters to further remove fine particles and sediment.
  6. pH Adjustment: Modifying the pH level to ensure optimal conditions for subsequent treatment stages.
  7. Activated Alumina Treatment: Utilizing activated alumina to reduce fluoride levels in the water.
  8. Storage Tank: Storing treated water to allow any remaining particles to settle before distribution.

Steps in Water Treatment

Each treatment stage contributes to the overall purification process:

  • Pre-chlorination ensures initial disinfection and bacteria control.
  • Flocculation aids in the removal of suspended particles, making filtration more effective.
  • Sand filtration captures larger particles, sediment, and debris.
  • Carbon filtration removes chlorine, odors, and organic compounds.
  • Brim filters target fine particles that may have escaped previous stages.
  • pH adjustment creates optimal conditions for fluoride reduction.
  • Activated alumina treatment reduces fluoride content.
  • The storage tank allows for settling and further purification.

Role of Each Treatment Stage

Every treatment stage serves a specific purpose:

  • Disinfection and Preparation: Pre-chlorination sets the stage for effective purification.
  • Particle Agglomeration: Flocculation encourages particles to bind together, making them easier to remove.
  • Initial Filtration: Sand filtration removes larger particles and sediments.
  • Residual Contaminant Removal: Carbon filtration addresses residual chlorine, odors, and organic compounds.
  • Fine Particle Elimination: Brim filters target finer particles to enhance water clarity.
  • pH Adjustment: pH control ensures the next stages proceed efficiently.
  • Fluoride Reduction: Activated alumina treatment effectively reduces fluoride levels.
  • Clarification: Storage allows particles to settle, improving water clarity.

Benefits of General Purpose Water Plants

The use of general-purpose water plants offers several benefits:

  • Versatile Water Usage: The treated water can be used for various non-drinking purposes, reducing the strain on drinking water supplies.
  • Effective Contaminant Removal: The multi-stage treatment process ensures the removal of fluorides, iron, and suspended solids.
  • Resource Efficiency: Instead of using high-quality drinking water for non-potable purposes, this method optimizes resource use.

Applicability in Residential Buildings

This water purification method is particularly suitable for residential buildings with high water demands. As water is needed for activities like cleaning, washing, and irrigation, the treated water serves these purposes effectively.

Precautions and Considerations

It’s important to note that the treated water, while significantly improved, is not suitable for direct consumption or cooking due to its high total dissolved solids (TDS) content. TDS levels above 1000ppm make it imperative to pass the water through reverse osmosis to bring the TDS below 100ppm before it can be considered safe for drinking.
