Submerged turbine operating at low speeds combined with an air blower for oxygen input. The Sofie® Submersible Aerator/Agitator is a mixing unit for extremely challenging applications. The units minimise blocking or clogging, the Sofie® can be used as an aerator or an agitator for wastewater treatment. Sofie® is designed to be installed at the base of tanks and to operate either in aeration or in a mixing mode. Sofie® is a good alternative to mechanical fine bubble aerators and is suitable for ponds with oxygen or mixing requirements.

Multi-purpose, multi-directional, submerged mixer ideal for general mixing and flow generation; adaptable to many tank configurations. Open, dual helical impeller providing intensive; directional sub-surface mixing pattern with minimal surface disturbance and low power to volume performance 1.5 – 22KW Drive Motors 4 + 6-Pole Speeds, Direct Drive AISI 304/316 or other SS Submersible motor – ip 68 protection High quality, low maintenance motor Robust + compact design – minimal vibration Easy installation + removal Directional mixing + flow generation plus general mixing of lagoons Basins + tanks activated sludge processes vey large surface area reservoirs Denitrification + sbr + asp

Diffusers designed for aeration of activated sludge basins and tanks in Municipal and Industrial wastewater treatment plants. Quick and easy to assemble by Rotating Diffusers clockwise into Screwed connection. Designed to give optimum performance. DIFFUSER BODY The manufacture of this component in Glass Reinforced Polypropylene gives it excellent resistance to abrasion, most chemicals with significant mechanical strength. EPDM MEMBRANE The EPDM Membrane prevents the penetration of water into the distribution pipework when the air is stopped. CLAMPING TYPE AQUADISC® 250-305: Clamps are manufactured in stainless steel or polypropylene and secures the membrane to the diuser body; AQUADISC® 320: Clamp made of glass fibre reinforced polypropylene. THREAD 3/4’’ CONICAL GAS TYPE FITTING Allows Aquadisc® difusers are mounted by simple turning clockwise

Exceptional mixing performance for both low and high solids concentration solutions. Intensive, low-energy, 360 - degree mixing pattern and totally non-clogging impeller. 1.1 – 30KW Drive Motors 10-42 rpm Geared Drive AISI 304/316 or special SS Fixed Bridge + Floor Mounted High efficiency mixing of basins + tanks Activated-sludge processes Denitrification + sbr Also ideal for deep tanks + high mlss Intensive low energy to volume mixing Totally non-clogging design Minimal noise output Robust design – low maintenance
