Zero Wastewater Discharge Plant

In Zero wastewater discharge plant wastewater is treated to be used again. Wastewater is reused it is not released on the sewer system or surface water. Water is a scarce commodity hence its optimum utilization is must. Lots of effort worldwide is going on in order to conserve water. Many new technologies are also being developed for optimum utilization of water.

As per research millions of gallons of water go waste in various industrial applications. Therefore now technologies are developed to recycle and reuse these wastewater so that they can be again used.

Industries like paper and cellulose, textile, poultry, food and beverages, iron and steel, etc uses water for cooling and other purposes. Now the technologies are evolve for recovering and reusing these wastewater. This minimizes wastewater discharge.

Technologies Used
For different industry different types of process is adopted for wastewater recovery. For example textile and pulp industries use membrane filtration, like microfiltration, nanofiltration, ultrafiltration etc. Some units also adopt distillation process like Multistage flash distillation ( MSF), Multiple effect distillation (MED)etc. For better membrane solutions Membrane bioreactors are also used.

Industrial Applications
Zero wastewater discharge plant finds their applications in the following industries:

• Pharmaceutical companies
• Iron and steel industries
• Textile industries
• Paper and pulp industries
• Beverage industries etc.
