Filtration is a physical treatment technology that separates solid particles from a liquid by passing the mixture through a porous medium, allowing the liquid to pass through while retaining the solids.

Sedimentation relies on gravity to separate solid particles from a liquid. The denser particles settle to the bottom of the settling tank due to gravitational forces.

Incineration is a physical treatment technology that involves the controlled burning of waste materials at high temperatures, resulting in the conversion of organic matter into gases and ash.

A clarifier is a device used in wastewater treatment plants to separate solids from liquids. It allows suspended solids to settle to the bottom of the tank, while the clarified liquid is drawn off from the top.

Centrifugation is a physical treatment technology that utilizes a rotating drum or centrifuge to separate solid particles from a liquid. The centrifugal force generated causes the denser solids to move to the outer edge of the drum, while the liquid remains in the center.

Flotation relies on the principle of buoyancy to separate solid particles from a liquid. Air or gas bubbles are introduced into the mixture, causing the solid particles to attach to the bubbles and rise to the surface, where they can be skimmed off.

Magnetic separation is a physical treatment technology that utilizes a magnetic field to separate magnetic particles from a mixture. The magnetic particles are attracted to the magnetic field and removed from the mixture.

Screening is a physical treatment technology that separates solid particles from a liquid based on their size. A screen with specific openings is used to allow smaller particles to pass through while retaining larger particles.

Reverse osmosis is a physical treatment technology that utilizes a semipermeable membrane to separate dissolved solids from a liquid. The membrane allows water molecules to pass through while retaining dissolved solids.

Distillation is a physical treatment technology that involves the evaporation of a liquid and subsequent condensation of the vapor to separate volatile components from non-volatile components.

Electrostatic precipitation is a physical treatment technology that utilizes an electric field to separate charged particles from a mixture. The charged particles are attracted to oppositely charged electrodes and removed from the mixture.

Adsorption is a physical treatment technology that involves the accumulation of pollutants on the surface of a solid adsorbent material. The pollutants are held in place by chemical bonding forces.

Disc filtration is a physical treatment technology that utilizes a rotating disc covered with a filter medium to separate solid particles from a liquid. The liquid passes through the filter medium, while the solids are retained on the disc.

Ion exchange is a physical treatment technology that involves the exchange of ions between a solid ion exchange resin and a liquid. The ions in the liquid are replaced by ions from the resin, resulting in the removal of pollutants from the liquid.

Gas separation membrane is a physical treatment technology that utilizes a semipermeable membrane to separate gases from a mixture. The membrane allows certain gases to pass through while retaining others.
