Reverse Osmosis

Computer Systems & Laptops

A computer is a machine that can be programmed to automatically carry out sequences of arithmetic or logical operations. Modern digital electronic computers can perform generic sets of operations known as programs. These programs enable computers to perform a wide range of tasks.

A laptop is a personal computer that can be easily moved and used in a variety of locations. Most laptops are designed to have all of the functionality of a desktop computer, which means they can generally run the same software and open the same types of files.

Computer Components and Hardwares

Basic hardware components of a personal computer, including a monitor, a motherboard, a CPU, a RAM, two expansion cards, a power supply, an optical disc drive, a hard disk drive, a keyboard and a mouse Inside a custom-built computer: power supply at the bottom has its own cooling fan.

Accessories such as a keyboard and mouse may be essential in order to operate your computer. Others - such as headphones, cameras, graphics tablets and barcode readers - may be useful for specialist tasks or the facilitate certain ways of working.

The CPU runs everything. The Power Supply Unit powers everything. The hard drives and SSDs provide long terms memory storage. The RAM provides short term storage while running a program.

Reverse Osmosis

Reverse osmosis is a water purification process that uses a semi-permeable membrane to separate water molecules from other substances. RO applies pressure to overcome osmotic pressure that favors even distributions.

water filtration, reverse osmosis is considered one of the most all-around effective ways of eliminating water contaminants. Even residential-grade reverse osmosis filters can remove up to 99% of lead, asbestos and 82 other additional contaminants.

When pressure is added, to the higher level side, that is greater than the current osmotic pressure the flow will be reversed. This reversal allows the contaminant solution to be further concentrated and produces purified water. The adding of pressure to enact the reversal is called Reverse Osmosis or RO

Sewage Treatment Plants

Sewage treatment is a type of wastewater treatment which aims to remove contaminants from sewage to produce an effluent that is suitable to discharge to the surrounding environment or an intended reuse application, thereby preventing water pollution from raw sewage discharges

Sewage treatment plants collect, treat, and discharge wastewater, providing a service essential to environmental and public health. Without adequate treatment, sewage will leach into the environment and contaminate ecosystems.

Domestic sewage treatment plants typically comprise of one or two chambers and utilise aeration to break down solids. After aeration, the remaining solids, including microorganisms, settle to the bottom of the tank to treat the next batch of wastewater.
