Waste Water Management

IM Analytics key drivers for wastewater treatment

To protect the sea shore
To protect marine life
Protection of public life
To prevent groundwater pollution
It's a matter of caring for our environment and for our own health.
Solving social problem caused by the accumulation of wastewater.
To reuse the treated effluent, for agriculture, for groundwater recharge, for industrial recycle
If wastewater is not properly treated, then the environment and human health can be negatively impacted.

We have a team of experts who carry out sewage treatment according to four major stages as follows

1

Pre-treatment

2

Primary Treatment

3

Secondary Treatment

4

Tertiary Treatment

The first stage is the Pre-treatment.

Any sewage may invariably contain trash, tree limbs, leaves and hard raw substances. They may be large in sizes and shapes and also denser to move. In this stage itself, these are to be removed first, other-wise, they may affect the other subsequent processes.

The second stage is the Primary treatment stage.

This stage consists of temporarily holding the sewage in a quiescent basin where heavy solids can settle first at the bottom of the basin. And at the same time, oil, grease and lighter solids may float to the surface of the basin. These settled and floating materials are removed in this stage. The remaining liquid may be discharged or subjected to the next stage of treatment.

The third stage is the Secondary treatment.

In this stage steps are taken to remove the dissolved and suspended biological matter. The processes are performed by indigenous, water-borne micro-organisms in a managed habitat. Secondary treatment may require a separation process to remove the micro-organisms from the treated water prior to the discharge for subsequent treatments.

The fourth stage is the Tertiary treatment.

In this stage, the treated effluent is allowed into a highly sensitive or fragile ecosystem like an estuary, low-flow rivers, coral reefs, lakes and ponds. The treated water is also disinfected chemically or physically prior to the discharge into a stream, river, bay, lagoon or wetlands. This water can be used for the irrigation of a grass-land, meadows, golf course, green ways or parks. If it is sufficiently clean, it can also be used for groundwater recharge or agricultural purposes. 5 Each stage has its own sequence of processes to be completed in sewage treatment. It is also necessary to fully comprehend and execute the essential steps involved for a better delivery
