Waste Water & Storm Water

Watmov Engineering Pvt. Ltd is a technology-driven consultancy with a strong presence across the globe in the field of Waste Water and Storm Water with exceptional service in Sewage treatment plant consulting in India. Watmov™ designed total 150+ MLD Sewerage Treatment Plant.

Sanitary engineering starts at the point where water supply engineering ends. Sanitary engineering starts with the collecting system and ends after the streams or other bodies of receiving water have been returned to the condition of relative purity desired for them.

-Collection works

-Treatment works

-Disposal works

To remove various contaminants present in sewage so as to produce an effluent and sludge which can be disposed off in the environment without causing health hazards or nuisance. The contaminants in the domestic sewage are present in the form of Suspended (settleable, Non-settleable );Colloidal and Dissolved solids.

The objective of the treatment process involving various

(i) Operations/processes or

(ii) Combination of operations and processes ; by which the contaminants are stabilized and removed.

Aerobic Treatment -Treatment process for raw wastewater or further polishing of pretreated wastewater

Aerobic treatment is a biological wastewater treatment process that takes place in the presence of oxygen. Aerobic biomass converts organics in the wastewater into carbon dioxide and new biomass.

Evoqua offers aerobic treatment systems for both municipal and industrial facilities looking to treat raw wastewater and/or polish anaerobically pretreated wastewater. Ultimately, further reducing biochemical oxygen demand (BOD),
total suspended solids (TSS), nitrogen, and phosphorus. Aerobic treatment systems can also be used specifically to
remove nitrogen and phosphorus in the process known as biological nutrient removal (BNR).

Anaerobic Treatment – Energy Efficient solutions for treating wastewater prior to discharge or further polishing

Anaerobic digestion is a biological process in which organic wastes are broken down by microorganisms in the absence of oxygen. An anaerobic system can be used for pretreatment prior to discharging to a municipal wastewater treatment plant or before polishing in an aerobic process.

Anaerobic treatment is typically utilized to treat warm, high-strength industrial wastewater containing high concentrations of biodegradable organic matter. This energy-efficient process reliably removes biochemical oxygen demand (BOD), chemical oxygen demand (COD), and total suspended solids (TSS) from wastewater.

How Sewage Treatment Plant STP Work?

A sewage treatment plant STP cleans wastewater by converting it into cleaner water. The wastewater is filtered through a series of pipes with discs attached. These disks have small holes that allow air to enter the chamber and move the sewage from top to bottom. During the first stage of the process, the sewage passes through an aeration basin. The oxygen in the wastewater causes the bacteria in the sediments to digest organic matter and produce clean water. Secondary treatment removes the remaining sediment and pollutants and makes it safe for direct discharge to a watercourse or a sewer.

Once the wastewater has passed through the aeration basins, it flows into the final compartments of the STP. The final phase is called the activated sludge process. This process breaks down the solids in the wastewater, which is then discharged back into the environment. This process is called a multi-stage system, as it treats the wastewater from many properties simultaneously. Once the sewage is treated, it will be
released into the environment.

The sewage flows into a primary clarifier. Here, the organic solids settle to the bottom and are referred to as primary sludge. This blanket is pumped into the aeration basins. Next, the sludge will undergo a second stage, called the activated sludge process, which will break down the sludge into smaller particles. The sludge will eventually reach the surface and be discharged into the environment.
