Gas and air scrubbers
Gas scrubbers are mainly used in industrial processes to rid the air (gas) of certain substances. A scrubber uses absorption. The purpose of a gas washer is to neutralize one or more pollutants in an (industrial) air or waste gas flow. The operation is based on bringing the waste stream into contact with a liquid (scrubber liquid). The scrubber liquid absorbs part of the (harmful) gas flow through absorption.
An air scrubber is used in intensive livestock farming to reduce the emission of hazardous substances and / or substances that harm the environment. There are two different types of air washers; namely chemical air washers and biological air washers. There are also combi air washers, first a chemical part and then a biological part. Chemical air washers work with the help of water with sulfuric acid, biological air washers with the help of bacteria. Chemical air washers only reduce ammonia and a large part of the dust, while biological air washers also reduce odors other than those of ammonia.
