SFA enviro - wastewater treatment

Manufactures floating and fixed aerators, decanters and mixers for sale or hire. Aerators work on the basis that liquid is aspirated via the suction cone and is pumped axially up through the cylindrical volute, after which its flow is bent from axial to radial, ensuring that maximum kinetic energy is transferred to the water surface. Also offers a

Manufactures floating surface mixers and submersible mixers for the industrial and municipal wastewater markets. The floating mixers use a helical-type centrifugal impeller to ensure high turbulence beneath the water surface, producing intensive mixing. With one model, the motor is totally enclosed by the float, allowing the mixer to be located

Manufactures mechanical intake screens designed to protect pumps, pipelines and downstream treatment equipment from debris and suspended solids. The range includes fine and coarse screening solutions suitable for river, canal, reservoir and seawater intakes. The screening systems operate continuously to capture floating and suspended material

Manufactures grit and silt removal systems designed to efficiently separate and extract abrasive inorganic materials from wastewater streams. The equipment range includes grit classifiers, grit separators and handling systems that protect downstream processes and reduce equipment wear. These systems operate by settling and separating heavier

Manufactures, amongst other products, devices that handle scum and floatable matter from the top layer of liquid in different types of tanks in WWTPs. One device is used to evacuate floatables to another tank, while another re-entrains the floatables into the mixed liquor. The devices are most often used in aeration tanks, but are also suitable
