Wastewater Management & Environmental Effects

       Wastewater Management!

Wastewater management is an important approach to protect water resources and it is defined as the collection, treatment, and reuse of wastewater. In wastewater collection network as one of important infrastructures, undesirable performance can lead to different problems.

There are three main stages of the wastewater analysis process, aptly known as 

1.Primary 

2.Secondary 

3.Tertiary water treatment.

 In some operation, more advanced treatment is required, known as quaternary water treatment.

Each of these stages managed different pollutants, with water becoming cleaner as it  passed through the phases.

Primary wastewater Treatment.

During primary treatment, wastewater is temporarily held in a settling tank where heavier solids sink to the bottom while lighter solids float to the surface.

Once settled, these materials are held back while the remaining liquid is discharged or moved through to the more rigorous secondary process of wastewater treatment.

These large tanks are also often operate with mechanical scrapers that continually drive collected sludge in the base of the tank to a hopper which pumps it to sludge treatment facilities.

Secondary wastewater Treatment.

Secondary treatment of wastewater works on a deeper level than primary and is designed to substantially disintegrate the biological content of the waste through aerobic biological processes.

Completing secondary wastewater treatment allows for safer release into the local environment, reducing common biodegradable contaminants down to safe levels.

It is done in three approaches, 

1. Biofiltration

Biofiltration uses sand filters, contact filters or trickling filters to establish that any additional sediment is mitigate from the wastewater.

2Aeration

Aeration is a lengthy process which increases oxygen assimilation by introducing air to wastewater. Typically, the aeration process can last for up to 30 hours, but it is very persuasive.

3. Oxidation ponds

Typically used in warmer climates, this method exploit natural bodies of water such as lagoons, allowing wastewater to pass through for a set period before being restrain for two to three weeks.

Tertiary Wastewater Treatment.

The prospect of tertiary wastewater treatment is to raise the quality of the water to domestic and industrial standards, or to meet appropriate requirements around the safe desposal of water. In the case of water treated by municipalities, tertiary treatment also involves the removal of pathogens, which ensures that water is safe for drinking purposes.
