Summary
This study demonstrates a viable industrial effluent treatment process for water recovery. An integrated ozonation and reverse osmosis system effectively removes contaminants, making water reuse feasible.
Area of Science:
- Environmental Engineering
- Chemical Engineering
- Water Treatment Technologies
Background:
- Industrial wastewater often contains challenging pollutants like salts and dyes.
- Effective water recovery and reuse are critical for sustainable industrial operations.
Purpose of the Study:
- To evaluate the technical and economic feasibility of treating industrial effluent for water recovery.
- To assess a combined ozonation and reverse osmosis process for industrial wastewater.
Main Methods:
- Characterization of industrial effluent (10 m³/h).
- Laboratory-scale treatment evaluation, including ozonation and reverse osmosis.
- Industrial-scale process design, equipment analysis, and economic assessment.
Main Results:
- The effluent contained sodium chloride, tartrazine, Red 40, and brilliant blue dyes.
- A coupled ozonation and reverse osmosis process was identified as effective.
- The scaled-up plant (130 m²) produces 7.7 m³/h of clean water.
Conclusions:
- The integrated ozonation and reverse osmosis treatment is technically and economically viable.
- The project offers a 3.4-year investment recovery period with a treatment cost of $1.4/m³.
- This approach provides a sustainable solution for industrial water reuse.

A number of natural and synthetic materials exhibit selective permeation, meaning that only molecules or ions of a certain size, shape, polarity, charge, and so forth, are capable of passing through (permeating) the material. Biological cell membranes provide elegant examples of selective permeation in nature, while dialysis tubing used to remove metabolic wastes from blood is a more simplistic technological example. Regardless of how they may be fabricated, these materials are generally...

04:01Factors Affecting Solubility
33.0K
Compared with pure water, the solubility of an ionic compound is less in aqueous solutions containing a common ion (one also produced by dissolution of the ionic compound). This is an example of a phenomenon known as the common ion effect, which is a consequence of the law of mass action that may be explained using Le Chȃtelier’s principle. Consider the dissolution of silver iodide:

In ozonolysis, ozone is used to cleave a carbon–carbon double bond to form aldehydes and ketones, or carboxylic acids, depending on the work-up.
Ozone is a symmetrical bent molecule stabilized by a resonance structure.

1.7K
Precipitation and coprecipitation methods can be used to separate a mixture of ions in a solution. In qualitative inorganic analysis, ions that form sparingly soluble precipitates with the same reagent are separated based on the differences in solubility products. For example, consider the separation of Cu(II) and Fe(II) ions by precipitation as insoluble sulfides. First, copper(II) sulfide is precipitated by the addition of acidic H2S, where the dissociation of H2S is suppressed. Adding H2S...
