Hydromax supplies surface aeration systems engineered to transfer oxygen efficiently into lagoons, oxidation ponds, and open-air wastewater treatment basins. Each unit is selected for basin geometry, required oxygen transfer rate, and local operating conditions.
From floating aerators in remote ponds to paddle wheels in extended aeration plants, our surface aeration solutions deliver consistent dissolved oxygen levels with minimal maintenance.
Submerged diffuser systems that introduce air at depth for high oxygen transfer efficiency in activated sludge, SBR, MBR, and biological nitrification processes.
Membrane disc and tube diffusers that produce bubbles smaller than 3 mm, maximising air-water contact area and achieving standard oxygen transfer efficiencies of 20–35% per metre of submergence.
Hydromax supplies EPDM and PTFE membrane diffusers for activated sludge, MBR, and nitrification tanks, with grid layouts engineered for uniform floor coverage and minimum fouling.
Large-orifice diffusers that produce vigorous mixing action alongside oxygen transfer—well suited for equalisation basins, anaerobic pits, primary tanks, and applications requiring solids suspension.
Their open-pipe and perforated designs resist clogging in high-solids environments, making them the preferred choice for screening channels, primary clarifiers, and thickener aeration.
Jet aeration combines a liquid pump and air blower to inject a high-velocity air-water mixture into the tank, achieving powerful mixing and oxygen transfer in a compact footprint without submerged rotating parts.
Ideal for retrofitting existing tanks where diffuser grid installation is impractical, and for reactors requiring simultaneous intense mixing and aeration such as biological phosphorus removal systems.
Air supply machinery that drives your diffused aeration and process air networks—from efficient turbo blowers for large plants to robust positive displacement units for smaller installations.
Roots-type lobe blowers that deliver constant volumetric flow against varying system pressure—the workhorse of small to medium wastewater treatment plants where reliability and simple maintenance matter most.
Available in belt-drive and direct-drive configurations, Hydromax PD blowers are engineered for continuous 24/7 duty with oil-free air delivery and minimal vibration on steel or concrete bases.
High-speed single-stage centrifugal turbo blowers with magnetic or air bearings that eliminate oil lubrication—delivering 30–50% energy savings over equivalent PD blowers with exceptional part-load efficiency.
Ideal for large municipal STPs and industrial ETPs with variable aeration demand, turbo blowers integrate with DO-based control systems to modulate flow precisely and minimise energy consumption.
Multi-stage centrifugal blowers suited for medium to large flow applications where stable, oil-free air delivery at moderate pressures is required—commonly used in industrial ETP and combined treatment systems.
Hydromax centrifugal blower packages include inlet filters, silencers, check valves, and control panels configured for standalone or PLC-integrated plant operation.
Screw and helical lobe blowers that combine the pressure capability of PD blowers with reduced noise and improved efficiency—a practical choice for plants seeking an upgrade from traditional Roots-type units.
With built-in sound attenuation and internal compression, rotary lobe blowers are well suited for enclosed pump rooms and urban treatment plants where noise limits apply.
Aeration systems configured for the specific biological process—matching oxygen demand, mixing intensity, and basin geometry for each treatment technology.
Time-sequenced aeration for sequencing batch reactors, with precise on/off control coordinated with the fill, react, settle, and decant cycle for biological nitrogen and phosphorus removal.
Dual-purpose aeration for membrane bioreactors—process air for biological treatment combined with scouring air for membrane cleaning—configured to maximise permeate flux and minimise fouling.
Surface and submerged systems for facultative, aerobic, and polishing lagoons—designed to maintain aerobic conditions, reduce BOD, and control odour across large water surface areas.
