Water treatment plants treat water from several sources like lakes and rivers. Water from these sources needs to be processed to eliminate floating objects such as sticks and other solids of bigger dimensions, finer particulate matters, color, odor, pollutants, and harmful germs and microbes.
The water entering the treatment plant moves through intake screens to eliminate floating objects and bigger insoluble materials. Back-flushing of the display with air is done occasionally to clear the display and take care of the power of the screen.
Coagulants are added to the water to ease the following sedimentation procedure. Water containing the remaining impurities is taken to a sedimentation tank comprising sand filters to remove suspended solids. Sand is then recovered and cleaned so it can be reused.
‘Small size wastewater treatment tank’ (which is also known as ‘ถังบำบัดน้ำเสียสำเร็จรูปขนาดเล็ก‘ in the Thai language) are utilized to purify and lower the COD levels in the water. Various procedures are used in these plants including precipitation, coagulation, ion exchange and reverse osmosis. These plants are commonly used for separating suspended solids from lake and river water.
The following process is that the bacterial disinfection and degradation of the organic compounds by treatment with ozone gas. Ozone, being unstable, is produced onsite by using oxygen in an electric discharge unit. The ozone thus produced is bubbled through water. Residual ozone is then converted into oxygen gas and vented to the air.
Science and technology have given birth to a lot of procedures and methodologies that are beneficial in the conversation of the water. Amongst different, reverse osmosis (RO) is a filtration system which easily removes several kinds of large molecules and ions from the solutions.
In the reverse osmosis systems, the solvent naturally moves from an area having low solute concentration through tissue into the area having high solute concentration. This system is a most frequent process that’s used for purification of the drinking water and also salt and other materials are removed from the seawater.
There are lots of types of waste, municipal waste (household waste) a fluid is one of those environmental issues which very well interfere with the present watercourse. It’s due to some content in the waste, such as biological and chemical rubbish. These residues can in principle be divided up by itself in nature, but it is going to have quite a while for neutering.
