Some common methods employed: Some techniques or methods usually employed are- landfill in which they fill the waste in the land and cover it.
In the process of incineration the management uses the method of combustion to convert the waste into the gaseous form.
The most important is the recycling of the waste.
Along with these the biological recovery and energy recovery are also useful.
What are treatment plants? Treatment plants are useful to protect the environment in which the experts or engineers work in the different fields.
The protection of the environment through the different treatment plants are sewage treatment plant in which the BOD I is the main factor which is reduced by the process of removing the colloidal along with some solid suspended part which can easily be removed.
The other way is in which reducing of the BOD depends on the biological way of consumption of the objects.
The water treatment with the help of ultraviolet, reverse osmosis, ozone treatments are useful to get the clean water for reusing.
It also makes hard water easy to use by softening the water.
Engineering services that are environment friendly There are many different engineering services for the environment which are beneficial to the people and industries in varied aspects.
The different services are provided to ensure the environment is not harmed, in which waste management is quite essential.

• The municipal solid waste management is one of the perfect services for the residential and commercial areas.
  
• The other service is the use of treatment plants which is also useful for reducing the suspended part in various processes.
  
• The service of collection conveyance system is useful for the reusing and saving of water supply distribution and storm water disposal in various areas.
  

Laboratory services Laboratory services are used to analyze different object and for that a laboratory must have the required equipments and the well trained staff as the professional's chemist, microbiologists and other talented staff for wet analysis and the conventional analysis.
The various analytical activities are required for the different tests.
These are physical tests, chemical tests, biological tests, and many other test treatments for finding out the perfect solution to save the environment from every aspect.
The various process is done to get the knowledge about the matters and also useful to decide the way of reducing it.
Summary: Explaining what treatment plants are and how they are needed in different areas, the article highlights the importance of engineering services that are environment -friendly.
The various types of laboratory tests are also employed in industries to check for the most apt methods.
The people should always appreciate and contribute the necessary help to those organizations which are ready to help the environment.
