Zero Discharge
Zero liquid discharge (ZLD) refers to a treatment process in which the plant discharges no liquid effluent into surface waters, in effect completely eliminating the environmental pollution associated with treatment. Apart from this benefit, ZLD process also makes effective use of wastewater treatment, recycling, and reuse, thereby contributing to water conservation through reduced intake of fresh water.
Though the exact components of a ZLD treatment system will vary, a typical ZLD treatment system consists of a wastewater treatment system, ultrafiltration (UF) and reverse osmosis (RO).
Biogas Power Generator
Biogas is a by-product of an anaerobic wastewater treatment system. Biogas has an energy value of 21,474kJ/Nm3 and can be used for electric power generation. Other than that, Biogas can be also used as alternative fuel for boiler, hot water generation etc. Excess of biogas should be flared by highly efficient combustor and burner for total organic carbon destruction in an enclosed / semi / open flare system.
Benefits
- Energy recovery
- Cost saving
- Renewable energy
- Environmentally friendly
Wastewater Reclamation System
Wastewater reclamation, also known as water reuse, is the process of treating wastewater to remove contaminants and make it safe to be reused for various purposes. The process typically involves multiple stages of physical, chemical, and biological treatment to remove solids, organic matter, and other contaminants.
The treated industrial wastewater can be reused for a variety of non-potable applications, such as cooling tower makeup water, and industrial process water. By recycling wastewater, industries can reduce their water footprint and mitigate the impact of their operations on the environment. Additionally, reusing wastewater can be a cost-effective alternative to using freshwater sources, especially in areas where water resources are scarce or expensive.
