Choose the most economical plant design for your sewage treatment plant


Sewage treatment plants are used for removing harmful bacteria and parasites from waste material .The layout and process streams are designed in such a way that plant operates with minimum shutoff. It is the best way to improve the structural stability of the soil. We should choose sewage plant design according to our needs and requirements.

What is sewage treatment?
Sewage treatment is a method by which we can remove contaminants from water. Sewage is basically a combination of industrial and domestic wastes. It contains harmful bacteria, suspended solid and ions.
The untreated sewage negatively affects the environment as well as human health, so it is very crucial to focus on waste management through various sewage treatment plants. The sewage can be treated in septic tanks and bio filters. Sewage treatment is also known as wastewater treatment. It is of two types-On-site System and Effluent system.

How does sewage treatment plant works?
The working of sewage treatment is similar to the septic tank. Mechanical components are used to break the solid particles for producing clear liquid. Wastewater and sewage are fed into primary settlement tank in order to separate solid and liquid particles. Then pump aerates the waste for breaking and purifying the organic matter and after that it leaves from humus chamber and that time the effluent is almost 95% clean and ready for its disposal into water bodies and drainage systems.

Why do we need to treat sewage?
Environmental reasons
Sewage contains phosphorous and when it is discharged into water it causes excessive aquatic plant growth that leads to water degradation.

Recycling purpose
Sewage can be recycled for different purposes like cooling, toilet flushing, car wash and many more.

Public health
Untreated sewage contains bacteria and parasites and exposure to such waste can cause severe illness and diseases. So it is very important to treat waste before releasing it into water.

Phases of Sewage Treatment
Pre-treatment
In this phase of sewage treatment, large solids and grits are removed by the process of screening and it is then disposed in landfills.

Primary treatment
After pretreatment, the solid particles come to bottom and oil and grease comes upwards. The solid particles then scrapped off and scum is removed and these substances combine to form sludge.

Secondary treatment
In this phase sludge is treatment is treated in a sludge digester and sludge is converted into biogas which is a mixture of CH4 and CO2 gases and this gas is used for generating electricity for the plant. The liquid is then treated by the bacteria which break the remaining organic matter .After that it is sent to the oxidation ponds where heterotrophic bacteria again break down the organic material and then solar UV light destroys the harmful bacteria.

Conclusion
Sewage treatment plants are used for effective waste management. It is important to treat waste in order to make our environment pollution free. Land is very expensive these days, so companies should choose the right designs so that sewage treatment plants can be installed anywhere.

Importance of Frequent Septic Tank Maintenance


A septic system functions as a mini sewage treatment system mostly constructed on homes situated in areas wherein access to native sewage system is fairly difficult. While most of them are built to last for a lifetime, inappropriate septic tank maintenance could lead to harm and early breakdown of the septic system. Thus essential points have to be remembered in order to retain an operational septic tank system.

Septic Tank Maintenance

Controlling water input

Water input might seem to have no influence in everyday usage, however wastefully water going down the tank might cause a lot of problems. Overburdening the tank with water can slow down the anaerobic consumption process within the system. Excesses on the drain field or seepage field can also happen that includes floating scum except the liquids inside the container that might further root health and environmental problems.

Chemicals Should Not Be Flushed or Pour Down the Drain

Bleach used in washing the kitchen sink and bathroom is being drained to the tank and can be pretty detrimental to the system. However, it may seem harmless; it in point of fact hinders the natural biotic decomposition procedure inside. Usage of more recent oxygen based bleach for housework is suggested. Bleaches and other highly intense chemicals as well as diluents, paints, grease and other inert chemicals such as insecticides can cause harm to the tanks components.

Natural Bacterial Septic Tank Extracts

Contrary to standard belief, chemicals like bleach must not be used. Right care consists of adding natural microorganisms into the tank. It upturns its effectiveness in breaking down the discarded material. By growing the natural biological movement in the tank it can inverse a failing system into a better waste management system.

Septic Tank Maintenance
Regular septic tank inspection

While this might only be necessary a few times in a year, it is vital nevertheless to escape abrupt problems happening to the system. Subject to the capacity of the tank, time to time maintenance procedures should include inspection of the general septic tank system. It should also include checking levels of stored solids, floating scum along with the water being ejection by the system to the gutter field.

Understanding the above things as well as applying them in daily use can lead to more active septic tank. Appropriate septic tank maintenance might not seem crucial to most of the home owners since its jobs are well hidden within the household, nonetheless if intentionally neglected could lead the owner to face costly repairs, along with health and environmental issues.
