Blowers are an indispensable tool for successful wastewater treatment. Thanks to such devices as pressure blowers, it is possible to pump air under appropriate pressure in order to optimize treatment (including aeration – e.g. of sewage and various types of tanks). Blowers allow compression of air and gases in a low-pressure manner. These devices operate both as compressors and vacuum pumps. They are also used to rinse filters in water treatment plants, or in desulphurization.
Increasingly popular are modern blowers designed in a way that not only increases the efficiency of treatment, but also maximizes the safety of the entire process. These types of blowers are characterized by appropriately shaped rotors – these are called rotary blowers. Rotors with profiled gears make the blower extremely effective (thanks to higher speed and at the same time stability in operation) and quieter than traditional models. These types of rotors also make the operation of the blower safer. It is also worth noting the extended service life of this type of equipment and minimal failure rate.
Greater comfort, including quieter operation of modern blowers, is also influenced by the use of appropriate aggregates and sound-absorbing materials (anti-pulsation, with different types of silencers).
Types of blower units
On the market it is possible to find various types of aggregates suitable for blowers. These include: standard, vacuum or under-pressure aggregate. The aggregates are equipped with many additional functions, which allows them to be adapted to various purposes, including more efficient wastewater treatment. The unit can be equipped with additional sensors to control the blower and the motor to optimize its efficiency.
Blowers are highly automated, which makes their operation efficient and much easier. Parts such as belts and filters, which are essential for proper functioning, can be easily replaced on modern blowers. The monitoring system allows timely inspection and subsequent oil changes. Automation also simplifies access to the various blower components.
The monitoring system not only makes the blower operate more efficiently, it also makes the entire equipment more stable. Typically, monitoring will include blower parameters such as speed, pressure in various components, temperature, oil temperature and oil level.
Most wastewater treatment projects can be successfully “serviced” with commercially available model blowers. It is also possible to order blowers individually customized to meet non-standard technical conditions. Therefore, blowers can be equipped with additional systems to meet increased sealing, safety or cooling needs, for example.
These and other parameters can be achieved through the experience and innovation of leading blower manufacturers. We should remember – if we care about the quality of the equipment we purchase – it should always have the required national and EU certificates, such as PZH and ATEX: PZH and ATEX.
