In order to prevent obstruction, physical harm, and erosion of downstream water and wastewater systems like membrane filtration or discharge into sewer systems, coarse filtration serve the purpose of eliminating suspended large solids from wastewater.

Below methods are all part of the coarse filtration process:

• The Hydrocyclone system is an ingenious apparatus that utilizes centrifugal force to effectively separate liquids from high-density solids, specifically targeting substances like sand.
• The Shaker Screen possesses the ability to effectively purify a wide array of substances in large quantities. It can adapt to different levels of throughput while proficiently segregating particles of both small and large sizes.
• The primary purpose of a Stationary Wedge Wire Screen is to effectively divide and extract sizeable suspended particles from wastewater.
• The ingenious design of the Rotating Wedge Wire Screen ensures highly efficient separation of liquid and solid components in the processing of red meat, pork, poultry, seafood, and vegetables.
• Bag filters are used for the clarification/filtration of fluids that have a relatively small loading of particles to be removed. The particle suspension passes through and the particles settle in the bag.
• A cartridge filter is a piece of tubular filtration equipment that can be used across various industries for an array of filtration requirements. A cartridge is encased within a housing or a casing and used to remove unwanted particles, pollutants, and chemicals from liquids.
• A media filter is a type of filter that uses a bed of sand, peat, shredded tires, foam, crushed glass, geo-textile fabric, anthracite, crushed granite or other material to filter water for drinking, swimming pools, aquaculture, irrigation, oil and gas operations, and other applications.
• The Auto Backwashing Filter is a revolutionary system that effectively eliminates solid particles from various types of water and low viscosity liquids. This compact and highly efficient filter boasts an extensive flow rate, providing an unparalleled level of performance.
