Effective Techniques to Treat Wastewater

In a fast-urbanizing country like India, where freshwater is scarce, wastewater treatment is critical.

To address surface water quality challenges in quickly increasing and emerging cities, state and non-state entities have gradually shifted their attention to new innovative wastewater management systems.

Wastewater Treatment usually includes three basic stages, which are known as primary, secondary, and tertiary.

Each stage purifies water to a higher level. In certain cases, just one or two phases are required.

The level of treatment required is determined by the intended use of the water and the environment into which it will be discharged.

India’s progress in wastewater treatment is gradually increasing, resulting in the innovation of various new modules.

Let us give you an insight of some of these that have already started creating an evident impact on a majority of the country’s industrial landscape:

1. The CSIR-Central Mechanical Engineering Research Institute in Durgapur has introduced the world’s first Waste-Water Treatment Technology Model, which filters wastewater for irrigation and farming purposes and uses all three stages of wastewater management. It is called the Aqua Rejuvenation Plant (ARP). It is an Integrated Waste Water Rejuvenation Model that has a Six-Stage purification profile for the comprehensive treatment of Waste Water based upon diverse purification parameters. The system also has dual benefits as while the treated water is being used for irrigation purposes, the filtered sludge generated is also utilized as manure or a fertilizer.
2. A consistent issue in India has been that low-income users often cannot afford the high cost of treatment technology for treating oily wastewater from their sources. As a result, a large amount of unwashed oily wastewater is discharged into the water without following the guidelines of the Pollution Control Board. In order to find an apt solution to this issue, Dr Chiranjib Bhattacharjee, Professor at the Chemical Engineering Department at Jadavpur University, created an Electrocoagulation and Electroflotation Enhanced Membrane Module (ECEFMM) technique for wastewater treatment. This membrane module is a part of the tertiary stage of wastewater management. With the use of this innovative module, the vehicle maintenance industry, food industry, and other small and medium-sized businesses can have a smart, cost-effective electric field-assisted membrane separation device for oily wastewater treatment.
3. Technologies using UV photocatalysts can treat urban sewage and highly polluted industrial wastewater streams. This has been made possible by The Energy and Resources Laboratory in New Delhi, which has developed a technology called  Advanced Oxidation Technology (TADOX). It reduces dependence and stress on biological and tertiary treatment systems and helps achieve zero liquid discharge. The most important change is the introduction of a “zero liquid” drainage system where treated wastewater is reused and not discharged into public sewers and water bodies. This technology has the ability to reduce Chemical Oxygen Demand (COD), Biological Oxygen Demand (BOD), dissolved organics, pathogens, Persistent Organic Pollutants (POPs), and Micropollutants. Hence, this technology is extremely efficient and budget-friendly.
4. The SCPI project, funded by the Federal Ministry of Environment, Nature Conservation and Nuclear Safety (BMU) Environmental Technology Export Initiative, is providing India with German know-how in wastewater treatment facilities. It shows how to adapt wastewater treatment to local conditions, reuse water, be suitable for groundwater recharge, and improve surface water quality.
5. Bioremediation is not any kind of a module or treatment plant but it is one of the processes that uses live microorganisms to break down pollutants and harmful microbes in wastewater. This is a very effective and inexpensive solution. Cases where bioremediation is commonly seen are oil spills, soils contaminated with acid mining drainage, underground pipe leaks, and crime scene cleanups. These toxic compounds are metabolized by enzymes present in microorganisms.

With all of these advanced and new innovations, the world of wastewater management will get a new approach and better ways of treating wastewater.

In addition to advanced wastewater management techniques, there are innovative and effective biological wastewater solutions that help treat wastewater.

At Organica Biotech, we strive to become leaders in this space and have developed a wide range of solutions for wastewater treatment.

Our microbial Cleanmaxx contains a cadre of specialized microorganisms that help break down organic waste, reduce sludge volume, and effectively improve the performance of wastewater treatment plants.
