SFA ENVIRO - Equipment for the pre-treatment and treatment of municipal and industrial wastewater

Totally independent Aerator and Mixer. Air Provided by Blower with Variable Frequency Drive which can regulate oxygen supply from zero to maximum capacity; whilst retaining full mixing and oxygen dispersion capability therefore the units are ideal for SBR ASP & MBR applications.

As a floor mounted submersible aerator with intensive mixing action, it is ideal for deep tanks, existing pocket ASPs with moderate to high sludge concentrations and will re-suspend of settled sludge

Specifically designed for fixed or Float mounting which allow impeller immersion to vary in accordance with flow levels and associated oxygen demand. Ideal for Oxidation Ditches and Pocket ASP’s. 1.5 – 30kw Drive Motors 2 + 4-Pole + Dual Speed, Direct Drives Submersible Motor – IP 68 protection AISI 304 / 316 or special SS

Discharges the volume of clean water without disturbing the sludge blanket or floatable materials on the surface. Ideal for the SBR Process, Sludge Settling Tanks, Sludge Thickeners plus the general decanting process. Comprises of a Stainless-Steel float Circular Type – 10 to 150 m3/h Capacity Rectangular Type – 150 to 3,000 m3/h Capacity Custom manufactured AISI 304/316 or special Materials Can also be equipped with a pump which allows to transfer the water from the sbr to a basin located at a higher level Minimal sludge blanket disruption Adjustable flow rate Avoids discharge of floatable materials Straightforward design + installation

To assist bio-digestion FB aspirates and breaks high volumes of foam forming on the surface of some biological and thermophilic reactors. Foam is drawn into the volute where the degassing tube allows air to vent to atmosphere and liquid to re-entrain. Nothing is discharged from the basin. Applicable in high foam treating biological reactors, high foaming influent, thermophilic reactors, biological treatment of animal waste.

Radial Aspiration and Mixing floatable material with downdraft flow and dual action impeller. The homogenization phase allows re-entrainment with the biological process. FRED units prevent settlement and crust formation as well as mixing the entire basin. Nothing is discharged from the basin. Applicable for Viscous + sludge bulking applications and grease trap systems upstream of biological reactor SBR. 1.1 – 22KW Motors 4 – 6 Pole Speed, Direct Drive 2 + 3 Float Options AISI 304/316 or special SS Special dual action impeller Excellent mixing performance Reliable + non-clogging design Easy installation + removal

The FRMD is used to remove the upper layer of foam, oil or fats. The natural flow within the basin, together with the suction of the pump, attracts the surface of the water towards the center of the FRMD. An adaptable floating weir allows the upper layer to enter the pump and be removed from the basin. The weir and the submersible pump are mounted on a robust floating structure held in place by cables and springs or guiding tubes. Depending on the application and the geometry of the basin, the FRMD can be mounted together with a MIX SL (directional submersible mixer) or MIX-AS (floating downdraft mixer) to help the flow towards the weir. Applicable for removal of oil, fats, bulking + aging sludge, recycling of scum in sludge stabilisation + biogas, SBR and ASP tanks.

Open, two-bladed helical impeller providing intensive radial, sub-surface mixing pattern with minimal surface disturbance and extremely low power to volume performance Turbulent 3D radial mixing pattern 1.5 – 55kW Motor Range 4 + 6-Pole Speeds, Direct Drive Motor AISI 304/316 or other SS General-purpose mixer adaptable to most tank configurations plus applications and easily positioned for various process requirements Simple, robust, and reliable Non-clogging, no sheering action impeller Virtually zero surface turbulence and no aerosols No o2 transfer and easy to install and remove

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

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
