Water treatment equipment is a term that refers to all equipment that treats water.
The history of water treatment is long, dating back to BC. In the Mesopotamian civilization, sewage systems were already in place to detoxify water by allowing it to percolate underground. Until modern times, when combined septic tanks were used to render sewage harmless, various methods were used to treat sewage and contribute to public health.
The history of water treatment is mainly documented from the 19th century. In modern times, water treatment plants have been installed throughout the world.
Water treatment equipment is an integral part of our daily lives, yet it is rarely visible in the market; rather, it serves as essential infrastructure.
A typical example is a water purification plant. The water treatment plants owned by each municipality are huge water treatment equipment. They mainly submerge and filter drinking water, add chlorine to make it suitable for drinking, and then deliver it to homes and commercial facilities.
When it comes to wastewater treatment, sewage treatment plants form an integral part of the infrastructure that supports our daily lives. They are responsible for detoxifying sewage from the sewage system and safely discharging it into the ocean.
Water treatment equipment is classified into two main categories: feedwater treatment and wastewater treatment. Feedwater treatment is divided into desalination and purification. Wastewater treatment is divided into sewage treatment and industrial wastewater treatment.
Desalination treatment now uses a component called a reverse osmosis membrane. Reverse osmosis membranes are membranes that do not allow electrolyte ions such as chlorine to pass through. When seawater is filtered under pressure through a reverse osmosis membrane, only pure water is discharged to the filtrate side. In areas where there is no rainfall, seawater is sometimes desalinated and used as drinking water.
Water purification processes are installed throughout Japan. After sediment is submerged at dams and other facilities, chemicals are added to adjust the PH and submerged filtration is repeated. Finally, chlorine is added to sterilize the water, which is then sent to various locations.
In general, a combined septic tank is used for sewage treatment. Anaerobic microorganisms are used to treat the sewage into relatively harmless wastewater, which is then discharged into the ocean.
Industrial wastewater treatment shares a similar structure to water purification, with the key distinction being that the wastewater is ultimately discharged into the ocean. Due to the nature of the wastewater, PH treatment is performed by adding additives. The treated sludge is separated and filtered before being transported to a disposal site or other facility. The filtrate is discharged into the ocean after being treated as treated water in accordance with the agreement with the government and other authorities.
