A filter press is a solid-liquid separation device used to dewater sludge, separate solids from liquids, and filter materials in various industries, including wastewater treatment, chemical, pharmaceutical, and food processing. The primary purpose of a filter press is to efficiently remove liquid from a mixture and produce a dry cake material. The device comprises a series of filter plates with recessed chambers and a filter cloth or other filter media between each plate. The plates are typically made from materials such as polypropylene, stainless steel, or cast iron. The filter plates are assembled together, forming a stack with an opening in the centre for the feed to enter the chambers.

Pall rings are a type of random packing used in chemical processing and various gas and liquid treatment applications. These rings are typically made of materials like metals, plastics, or ceramics and are characterized by their cylindrical shape with several internal and external structural features. The key design elements of pall rings include a series of internal and external structural elements—inner crossbars or struts and outer cylindrical walls—that provide a high surface area within a relatively small volume. This configuration ensures efficient contact between gas or liquid and the packing material, facilitating processes like gas absorption, distillation, and chemical reactions.

A rotameter, also known as a variable area flow meter, is a device used to measure the flow rate of a fluid in a closed conduit. It operates based on the principle of a variable area, where the area of flow passage changes in response to the flow rate of the fluid passing through it. The typical design of a rotameter includes a tapered tube, often made of glass or plastic, with a smaller diameter at the bottom and a larger diameter at the top. Within this tube is a float—a spherical or cylindrical object—positioned in the path of the flowing fluid. As the fluid flows through the tube, the float rises, indicating the flow rate.

Tube settler media is a structured plastic component used in water treatment processes, particularly in sedimentation tanks or clarifiers. Its design resembles a series of inclined tubes or channels that facilitate the separation of solids from water within these tanks. Made from high-quality materials like polypropylene or PVC, tube settler media consists of multiple parallel tubes or channels arranged at an angle within the clarifier. These tubes are structured to increase the surface area available for particles to settle and accumulate.

Coarse bubble diffusers are a type of aeration device used in water treatment processes, particularly in wastewater treatment plants. They're designed to introduce large bubbles into water or liquid, aiding in the transfer of oxygen and mixing within the water body. These diffusers typically consist of larger apertures or openings through which air is released into the water. The bubbles produced are comparatively larger in size compared to fine bubble diffusers, which allows for more rapid ascent through the water column. This ascent facilitates mixing and helps in the aeration process by bringing oxygen from the air into contact with the water.
