Best Effluent Treatment Plant in bangladesh

Effluent treatment plants efficiently clean industrial effluents and contaminated water from outlet pipes, reservoirs, rivers, and lakes, among other places, and reclaim the water resource for use in a variety of ways. ETP is commonly used in industries such as textile manufacturing, pharmaceutical manufacturing, leather manufacturing, and chemical manufacturing. The best effluent treatment plant in Bangladesh can be found at Green Dot Limited. These are both highly effective and inexpensive!

What are Effluent Treatment Plants

An effluent treatment plant (ETP) is a wastewater treatment process (WWTP) that treats wastewater. It's mostly used in industries like pharmaceuticals, textiles, and chemicals where there's a risk of extreme water contamination. Effluent Treatment Plants are important in the treatment of both industrial wastewater and domestic sewage. Organic matter, inorganic matter, heavy metals, oil and grease, suspended particles, and other contaminants are all treated in an ETP plant's wastewater treatment process. Wastewater treatment plants are classified into chemical treatment, biological treatment, a combination of chemical and biological treatment, and thermal treatment.

How Does an Effluent Treatment Plant Work?

The treatment's conceptual approach includes the removal of suspended particles, dissolved organic matter, and the handling of sludge for disposal. The following processes are involved:

The purpose of the equalization tank is to balance the raw effluent from various processing units. The wastewater is collected in an existing mixed effluent tank before being pumped to an existing aeration tank that also serves as an equalization tank. The floating aerator homogenizes the effluent before pumping it to the neutralization tank for treatment.

Ph Control

The pH of effluent should be between 5.5 and 9.0. (BIS). pH neutralization is a technique for modifying the pH of the wastewater. Acidic waste (low pH): Bases are used to change the pH of a solution. Acids are used to modify the pH of a solution in the case of alkali waste (high pH).


Coagulation is a technique that involves mixing untreated water with liquid aluminum sulfate. After mixing, the tiny dirt particles stick together. This collection of particles combines to form larger, heavier particles that can be easily removed via settling and filtration.


Because water moves slowly in this process, the heavy particles settle at the bottom. The particles that collect at the bottom of a container are referred to as sludge.


Filtration is the process of removing particulates from water by passing them through a filter. The filters are made of layers of sand and gravel. Backwashing is required regularly to clean these filters.


Water is disinfected before it enters the distribution system. Water is disinfected and decontaminated using chlorine.

Sludge Drying

Sedimentation collects and settles solids before transporting them to drying beds. When the sludge thickness reaches around 300 mm, the charging should be stopped and the bed separated to allow natural evaporation to dry it off. This process takes about ten days.

Importance of Effluent Treatment Plants in Bangladesh

  • ETP is a wastewater treatment process that treats contaminants such as organic matter, inorganic matter, heavy metals, oil and grease, suspended solids, and so on. ETP methodology can be either batch process or continuous flow process.
  • This type of Effluent Treatment Plant ensures that contaminated and polluted water from industries is treated and made reusable before being released back into the environment. Without this treatment, humans will be unable to obtain clean, usable water for household chores.
  • These effluent treatment plants save energy, economically remove pollution effluent, and meet government standards.
  • Reduces the cost of off-site treatment. Unnecessary water consumption during the processing is avoided. Makes your industry self-sufficient.
  • Aids in the reduction of contamination of natural water bodies and the preservation of the environment for future generations. The most cost-effective and environmentally friendly method is an effluent treatment plant.

Where to Find the Best Effluent Treatment Plant in Bangladesh

We live in a world where pollution is a major concern for the entire society. It can be of any type, including air, water, and others. As our society and industry expand on a large scale, water pollution increases by a factor of ten. As a result, industries must generate waste before discharging it into nature.

The role of ETP Plants in this process is critical. Effluent Treatment Plants (ETPs) are a type of wastewater treatment method that is specifically designed to purify industrial wastewater for reuse, to release safe water to the environment that is free of the harmful effects of effluent.
