Industrial wastewater treatment system and method for garment finishing, jeans and denim industry

A water reclamation system for the textile industry, comprising:

• [a] a primary module with separation means and a dirty water tank, [b] a secondary module with a treatment tank, ozone generating means, a recirculation circuit and a catalyst filter, [c] a tertiary module with filtration means, and [d] a treated water tank, wherein the separation means is a mechanical filtration system, and:
• the primary module is configured to receive wastewater provided to the water reclamation system;
• the mechanical filtration system is configured to remove particles from the wastewater thusly converting the wastewater to dirty water;
• the dirty water tank is connected to the mechanical filtration system and configured to receive from the mechanical filtration system dirty water;
• the treatment tank of the secondary module is connected to the primary module and configured to receive from the primary module dirty water;
• the ozone generating means are connected to the treatment tank and configured to supply to the treatment tank ozone for treating the dirty water in the treatment tank via the application of the ozone to the dirty water and the reaction of the dirty water with the ozone;
• the recirculation circuit is connected to the treatment tank and configured to continuously pump dirty water from and to the treatment tank forming a recirculation loop within the secondary module to promote therein the supply and mixing of ozone into the dirty water thusly promoting the reaction of ozone with the dirty water;
• the catalyst filter is configured to transform to oxygen any ozone that does not react with the dirty water in the treatment tank;
• the treatment tank is closed and sealed so that ozone application is made in a completely sealed enclosure;
• the tertiary module is connected to the secondary module and configured to receive from the secondary module dirty water that has been treated with ozone;
• the filtration means of the tertiary module are configured to remove particles from the dirty water that has been treated with ozone, thusly converting the dirty water to treated water;
• the treated water tank is connected to the tertiary module and configured to receive from the tertiary module the treated water;
• wherein the ozone generating means are arranged in the recirculation circuit;
• and wherein the treatment tank of the secondary module is connected to the primary module by means of the recirculation circuit, such that the treatment tank is configured to receive the dirty water from the primary module through the recirculation circuit.
