HR Blowers UK Ltd in the backwashing process

Referring to pumping water backwards through the filter media incorporating intermittent use of air during the process. The bubble effect agitates the solids, helping to release those solids making the process more efficient. Backwashing is a form of preventive maintenance so that the filter media can be reused. In water treatment plants, backwashing can be an automated process that is run by local programmable logic controllers (PLCs). The backwash cycle is triggered after a set time interval, when the filter effluent turbidity is greater than a treatment guideline or when the differential pressure (head loss) across the filter exceeds a set value.

They pump inert gas for fuel tank blanketing in tanker ships, and power emergency steering and braking systems on ships. Roots type blowers are used to load and unload dry bulk material ships and barges with pneumatic conveying systems. Cruise ships and military craft with large numbers of passengers or crew operating on board have the aeration process within wastewater treatment systems powered by roots type blowers. Marinas, locks and harbours use roots blowers to drive air bubbler systems to ensure equipment will operate at sub-zero temperatures.

HR Blowers UK Ltd in the mining industry.

Roots type positive displacement blowers are extensively used in the mining of most minerals, including copper, nickel, gold and diamonds. They are used to pneumatic convey dry bulk materials and provide air for oxidation processes and other refining applications. Roots type blowers are used to filter and dry slurry and power high capacity vacuum pumps. Many mines have large wastewater treatment facilities to allow for the decontamination of processed water, a process requiring roots type blowers for aeration.

HR Blowers UK Ltd in the waste water treatment works.

Roots type positive displacement blowers are used to aerate raw sewage and industrial organic waste. The aeration drives the digestion of the waste by microorganisms. Roots blowers are also used for grit tank cleaning, filter flushing, backwashing and the recovery of gases. Oil-free roots blowers are used for deep cell aeration.
Many treatment systems rely on the use of bacteria to digest and break down waste material during its processing. The suspended bacteria require a constant supply of oxygen in order to carry out their job efficiently. Positive displacement blowers solve this issue by continuously infusing oxygen into the system and facilitating the bacterial breakdown of waste. One of the benefits achieved by this kind of aeration is the reduction of odours produced during sewage processing.

HR Blowers UK Ltd and water aeration.

Aeration is a key process within wastewater treatment plants, forming the secondary treatment stage after solids have been removed. Roots type positive displacement blowers play an important part in this process because it provides the air supply that metabolises organic compounds in the wastewater and removes carbon dioxide.

During the aeration process Dissolved Oxygen (DO) probes monitor the levels of DO. That data is used to control the output of the roots type positive displacement blower to provide less or more air hence oxygen for the system.

HR Blowers UK Ltd in vehicle application.

Dry bulk transportation is the transportation process of dry materials. Most frequently these dry materials come in large quantities, and that is the main reason why many manufacturers are choosing this type of load transportation. Dry bulk transportation is used for transporting finely granulated, dry, as well as other pourable goods. Roots type positive displacement blowers are used to pneumatically convey the product to load and unload the vehicle trailer. The blowers can be mounted on the tractor unit, incorporated within the trailer or as part of a stand-alone on-site source of air for the pneumatic conveying.
