One of the most popular techniques for reducing pollution of water in India is wastewater treatment. Almost, all water treatment facilities employ a two-stage to three-stage approach and operate identically.
As we all know much about water treatment and its various stages, but are we aware about how efficient water management, can increase the lifespan of wastewater treatment pipes?
Let us go through the blog to have some insights.
Stages of wastewater treatment
Stage 1: Large screens are used in stage one, or primary treatment, to filter out floating objects like sticks and rags that could damage treatment machinery or clog pipes, if allowed to flow further into the system. It comes to an end with a stop in the sedimentation tank after screening, and treatment in the grit chamber.
Wastewater enters a grit chamber after screening. Small stones, sand, and gravel, among other types of debris, fall to the chamber's floor at this point.
Stage 2: Itis often known as secondary treatment, and eliminates about 85% of the remaining organic matter in wastewater, by utilizing bacteria.
A bed of stones that is three to six feet deep makes up the trickling filter. Sewage flows through the stone bed, where bacteria gather and eat the majority of the organic material. The cleaned water is then routed for additional treatment in a sedimentation basin, after trickling out through a system of pipes.
The activated sludge technique is another method of secondary wastewater treatment. In order to speed up the sewage's consumption, this procedure involves putting sewage in close proximity to bacteria and sludge.
Advanced treatment and disinfection of wastewater
Whichever method is employed, the process always ends with membrane treatment using RO Plants, as well as disinfection using chlorine, UV or ozone, and then discharge into receiving waters.
Consumers and companies frequently reuse the water because it has been treated so effectively. But occasionally other chemicals, such as aluminium sulphate, are also added to the water while treatment.
Use of coagulants during water or wastewater treatment
Aluminium sulphate acts as a coagulation agent, causing silt to coagulate and solidify into sludge. Aluminium molecules that are positively charged in their composition draw in the organic and solid waste particles. These impurities grow heavier and sink to the bottom for simpler removal, when the aluminium sulphate molecules interact with them.
But, the question arises! Do these coagulants cause negative effects on water quality?
Aluminium sulphate can produce hydrogen sulphide, a poisonous gas, when oxygen isn't present. This substance transforms into sulphuric acid, a very caustic and poisonous compound, when it comes into contact with oxygen.
In fact, it can reduce the lifespan of concrete water pipes by 90%, since it is so corrosive.By merely utilizing a coagulant that is sulphate-free, pipe life can be increased.
How to water management can increase life of wastewater treatment pipe?
Though it happens occasionally, switching the coagulating agent to a non-sulphate compound is straightforward. This is so, because water supply and water treatment agencies are typically separate in most places.
The least expensive coagulation agent, aluminium sulphate fits very well with the purpose of water treatment, which is to provide residential and commercial customers with drinkable water, at the lowest possible cost.
Despite not having any control over the chemicals used to treat the water, water supply providers are responsible for maintaining the pipes through which treated wastewater runs.
Integrating the two organizations will give them a shared goal and enable them to see that it is worthwhile, to forgo little increases in water treatment expenses to delay the premature deterioration of water supply concrete cement pipes.
