Our EMMI exhaust air scrubber system Exhaust air purification plays a key role in the approval of animal house systems. Investing in an exhaust air scrubber system can make approval procedures much easier. In fact, it is not only an extremely effective means of reducing ammonia, dust and odours but it also increases acceptance in the surrounding area and protects the environment. For many years, SCHULZ Systemtechnik has been dealing with this subject matter and has specialised in highly energy-efficient purification systems. At the same time, we are constantly further developing our...

System construction and control technology > Customised system construction > Container design (waterproof, chemical-resistant, no intermediate consumption on-site) When is it useful to build a multi-phase system? The exhaust air from most emission sources contains not only odour but also other exhaust air substances, such as ammonia and hydrogen sulphide, which must be removed from exhaust air. Multi-phase systems ensure effective and cost-efficient exhaust air purification. In each individual phase, a selective purification process takes place, which always leads to a considerably...

EMMI for poultry farming Our EMMI exhaust air scrubber system is divided into three purification areas (I to III), so that, in each case, only the necessary surface of the filter must be operated. The required purification phases are switched on or off only when emissions and exhaust air volume flows rise. This occurs, for example, on particularly hot days or when the animals have reached the end of the fattening process simultaneously. The fan units used are controlled through frequency converters. In this way, power peaks can be avoided and operating costs significantly reduced. The fact...

EMMI for pig farming The exhaust air arising from pig farming must be free from dust, odour and ammonia, in accordance with current legal requirements. Since the odour-eliminating microbiology is sensitive, we plan and construct exhaust air purification as a chemical/biological purification system. In fact, by using acids, ammonia can be highly effectively bound and thus removed from exhaust air. As a result, the subsequent biological phase can be carried out much more effectively. Furthermore, this configuration works immediately, with no need for long adaptation times. In pig farming, our...

EMMI for the industry Depending on individual requirements, in industrial application, a wide variety of substances must be removed from exhaust air, for example dust, odours or corrosive gases. In industrial plants, for example, a highly loaded process exhaust air flow must therefore be treated differently compared to that used for ambient air suction. This is only possible with multi-phase systems, which are planned and tailored according to customer requirements and adjusted depending on the exhaust air substances to be removed. Hence, exhaust air purification can be designed for almost...
