Ultrapure water is the water treated to obtain the highest purity levels for use in critical cleaning and process feed applications. Ultrapure water is primarily used in the semiconductor industry, power plants, and the healthcare sector. It is obtained by combining several filtering techniques, including reverse osmosis, ultrafiltration, and ion exchange. The processes for obtaining ultrapure water are monitored by stringent specifications and standards formulated by regulatory bodies.

Shale gas is a type of natural gas that is trapped within shale rock formations deep beneath the Earth's surface. It is a fossil fuel, like conventional natural gas, primarily composed of methane with small amounts of other hydrocarbons and trace impurities.

A heating and cooling system known as an air source heat pump pulls heat from the outside air and transfers it inside a building for space heating or cooling. It functions as an energy-efficient substitute for conventional heating, ventilation, and air conditioning (HVAC) systems by compressing refrigerant gas to absorb and release heat. Owing to their adaptability and suitability for use in commercial, industrial, and residential settings, air source heat pumps help save energy and have a smaller negative environmental impact.
