What pre-treatment stages need to be prepared for on-site wastewater systems?


Many industrial units in India treat their waste in Common Effluent Treatment Plant (CETP). They avoid having an on-site wastewater treatment facility due to high capital and operating costs. Many industries don’t have access to the water body even through the pipelines; hence they rely on municipal wastewater treatment plants to recycle the effluent.

However, before the industrial effluent enters CETP, there are some ground rules that these industries are asked to follow.

The industries must undergo pretreatment stages to meet basic standards set by the municipal corporation, and charges are reckoned back to the facility for water treatment costs.

The most basic pretreatment method that industries can opt for is monitoring effluent flow and controlling pH. Apart from that, the most common pretreatment biological units include:

Aerobic Digester
For decades, aerobic digestion has been considered to be one of the most efficient and emerging solutions for biowastes to help with environmental pollution and produce renewable energy. In the aerobic digestion process, the sludge volume of the effluent is reduced with the help of bacteria. This bacterial process activates in the presence of oxygen.

Aerobic digestion is used in the activated sludge treatment plant. This process is usually carried out in batches where the air is pumped through the tank, and the contents are mixed and sent for further treatment.

MBBR Aerobic System
A moving bed biofilm reactor is a biological treatment process where the microorganisms in the reactor decompose the organic waste, thus helping improve the overall water quality. It can function as a standalone process; however, it is often used as a comprehensive regime of wastewater treatment. This process is considered a vital function as part of a multi-step method for purification.

High Rate Fixed Film System
In this process, the fixed biomass combines aerobic, anaerobic, and anoxic zones and increases the Sludge Retention Time. This process also helps in promoting better nitrification compared to simple suspended growth systems. The system nitrification is restored faster, which improves its stability.

Compact SBR Type Unit
Many industrial units opt for the sequential batch reactor to improve and reduce sludge volumes in the wastewater treatment plant. Compact SBR Type Unit is a high-performance solution for wastewater treatment that can successfully handle batch and continuous flow operations. This technology comes with minimal costs and maintenance requirements. Due to its high removal capacity and versatility, it complies with stringent discharge standards. The distinct qualities of SBR-based sewage treatment plants are biological processes and high-quality product generation.

After understanding the importance of different systems that can be used for treatment, we need to learn how effective these treatments could be. Sometimes because of climate change or some technical glitch, the process underperforms, which can violate the PCB norms. During this time, it is essential to identify the problem before it worsens and find a solution.

Many wastewater treatment plant managers fail to identify the warning sites, which aggravates the situation. There are chances that the microbial strains can become dormant because of temperature fluctuation, and this can cause a rise in the sludge volumes.

Treatment plant managers usually look for wastewater treatment solutions to overcome these issues. The chemical treatment solution can resolve the problem for a certain period but cannot completely eradicate it. Our research team has devised Cleanmaxx, a microbial formulation that can help the effluent meet pollution control norms. Cleanmaxx contains beneficial microbial strains that can survive at any temperature and High TDS and overcome wastewater treatment issues such as foul odor, high BOD/COD levels, and reduced sludge volume.

Apart from being organic, we at Organica Biotech are also pioneers in the wastewater industry. Our bioremediation solutions are formulated after years of research, and we have helped several industries overcome wastewater-related issues. With our advanced microbial technology, we have treated over 10 billion liters of water globally to date.
