Water and Wastewater Treatment

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.

Water restoration is the process of improving water quality in rivers and other water bodies.

Chlorination, ozonation, and ultraviolet (UV) disinfection are all commonly used methods for disinfecting swimming pool water.

The primary role of a pool filter is to remove dirt, debris, and other suspended particles from the water, contributing to the overall cleanliness and clarity of the pool.

Cartridge filters are commonly used in spas due to their compact size, ease of maintenance, and ability to remove fine particles and contaminants from the water.

The primary purpose of using chlorine in water treatment for recreational applications is to disinfect the water by killing bacteria, viruses, and other microorganisms.

Using chloramines instead of chlorine can help reduce the formation of disinfection byproducts (DBPs) in water treatment, as chloramines are less reactive and produce fewer DBPs.

The primary role of a water park's filtration system is to remove dirt and debris, kill bacteria and viruses, and adjust the pH balance of the water to ensure a safe and enjoyable experience for visitors.

Rapid sand filters are commonly used in water parks due to their high flow rates and ability to handle large volumes of water, making them suitable for large-scale water treatment applications.
