Effect Of Winter On WWTP

The main goal of a wastewater treatment plant is to treat, degrade, and convert waste into satisfactory by-products that do not harm the environment.

Biological treatment of waste is a key process in wastewater treatment facilities.

The naturally occurring microbes play a major role in breaking down organic waste.

The wastewater thereafter consists of sludge and the effluent, which is released into the environment.

There are many factors which affect the performance of wastewater treatment system and one of them is temperature.

It is also an important parameter that influences the biological treatment of wastewater.

Therefore, during the winter season, wastewater treatment facilities face significant challenges.

One of the major effects of cold is the slowing down of the activity of helpful microbes available in the treatment plants.

Low temperature is not conducive to microbial growth, production, or metabolism.

Thus, the natural microbial community is unable to efficiently perform the function of breaking down organic waste reaching wastewater plants.

Moreover, it becomes difficult to manage the amount of Mixed Liquor Suspended Solids (MLSS) generated in the facility.

According to wastewater treatment experts, for every temperature drop of approximately 10 degrees F, microbes lose about one log of potential growth, equivalent to a 90% reduction.

Bacterial growth requires a temperature between 59°F and 113°F.

Additionally, the low temperatures associated with winter disrupt the effluent BOD and TSS limits.

It is estimated that BOD degradation rates drop and TSS increases during the winter season.

The sludge formation increases, and the removal efficiency decreases as well.

Other factors, such as dissolved oxygen, retention time, pH balance of the wastewater, and nutritional requirements, are drastically affected.

In winter months, the growth of filamentous bacteria causes a major problem for wastewater treatment plants.

It is predominantly caused by low dissolved oxygen, low F/M ratio, or high sulphide levels.

It causes serious settling problems.

Thus, it can be summarized that wastewater treatment efficiency decreases when the temperature is low, leading to disastrous consequences.

Elevated levels of waste in effluent make it toxic and harmful to the environment.

Various elements, such as nitrogen, are released into water resources, which causes eutrophication.

Aquatic animals suffer from a lack of oxygen. Humans who consume such water are also affected by various diseases.

The poor performance of wastewater treatment plants often leads to higher operation and maintenance costs.

It is essential to prevent problems rather than address issues when treatment facilities malfunction.

There are several solutions, such as increasing wastewater temperature and reducing waste loading, but these are not economical or efficient in the long run.

To overcome the mentioned challenges in the winter season, innovative solutions can be used to boost the performance of wastewater treatment facilities.

The biological degradation of waste can be enhanced by utilizing a specialized microbial community.

Organica Biotech is a leading company offering an extensive range of wastewater treatment solutions.

Cleanmaxx Aero is a specialized heterogenous concentrated consortium of uniquely functional bacteria that is active over a wide range of temperatures and pH.

It thrives in high TDS and low dissolved oxygen conditions, aiding in faster MLSS development during the winter season.

Moreover, it promotes rapid biomass generation capacity.

It can be used for all suspended and attached growth processes, including the Activated Sludge Process (ASP), Sequence Bed Reactor (SBR), Lagoon process, Moving Bed Bioreactor (MBBR), Membrane Bioreactor (MBR), Rotating Biological Contactor (RBC), and Fluidized Air Bed Reactor.

Using Cleanmaxx in the biological treatment process is one of the best methods to enhance and maintain the performance of wastewater treatment plants during winter.
