Rõhufiltrites

Rõhufiltrites refers to the Estonian term for pressure filters. These are a type of industrial filtration equipment designed to separate solids from liquids or gases under pressure. Unlike vacuum filters, where the pressure difference is created by a vacuum on the filtrate side, pressure filters utilize a higher pressure on the feed side to drive the fluid through the filter medium.

The primary function of a rõhufilter is to remove suspended impurities, particles, or contaminants from a fluid stream. This is crucial in various industrial processes to protect downstream equipment, improve product quality, or recover valuable solids. The design of a pressure filter typically involves a sealed vessel containing the filter medium. The fluid to be filtered is introduced into this vessel under pressure, forcing it through the medium. The solid particles are retained on the surface or within the pores of the filter medium, while the clean fluid passes through.

Rõhufiltrites are employed across a wide range of industries, including chemical processing, pharmaceuticals, water treatment, food and beverage, and oil and gas. Different types of pressure filters exist, such as plate-and-frame pressure filters, leaf filters, and cartridge filters, each suited for specific applications and filtration requirements. The choice of filter medium is also critical and depends on factors like particle size, fluid properties, and desired separation efficiency. Regular maintenance, including cleaning or replacement of the filter medium, is necessary to ensure optimal performance and longevity of the rõhufilter.
