Environmental Vacuum Applications
Biogas Production
A thorough mixing of the sludge in the sludge tanks increases the gas yield and reduces its retention time in the reactor. During the process, the gas is withdrawn from the upper part of the digestion tower, compressed and reintroduced through the nozzles at the bottom.
Compressed Air in Wastewater Treatment Plants
A thorough mixing of sludge with oxygen increases the gas yield and reduces its retention time in the tank.
Digester Gas Compression
The pump‘s operating liquid cools the digester gas by absorbing the heat of compression, thus providing an almost isothermal mode of operation. The cooling function of the operating liquid simultaneously acts as a flame arrester and reduces expenditures for explosion protection. The contaminated raw gas is cleaned, partially dried, oxygenated and returned to the wastewater treatment process.
Fish and Prawn Pond Aeration
In order to increase the water’s oxygen content, air is drawn from the atmosphere and forced through an inlet into the tube aerator. It is then diffused into the water through tiny openings and then rises in fine bubbles.
Suction Vehicles for Wastewater Cleaning
The suction pressure necessary for removing wastewater and cleaning sewer networks is provided by vacuum pumps.
Wastewater Disposal
Using central vacuum systems wastewater can be collected, drained and disposed of in complete housing areas at the same time.
Wastewater Purification/Oxygenation of Activated Sludge Tanks
Compressors supply the pressure required for maximum oxygen yield.
