Diffuser cover made of reinforced polypropylene Diffuser cover made of reinforced polypropylene Polypropylene mounting collar with A4 screw fixing Silicone gasket within the assembly Mounting on stainless steel pipe in DN40 or PVC 5 Mountings with smooth orifice/smooth air sleeve in polypropylene 30% glass fibre Mountings with tapped orifice/Air sleeve for tapped outlet in polypropylene 30% glass fibre Shark fin shape diffuser design limit the adhesion of solid and fibrous residues. Self-cleaning orifices whose profile privides the formation of homogeneous bubbles and avoids coalescence or breakdown The geometry of the self cleaning diffuser outlets guarantees the formation of homogeneous bubbles regardless of the air flow rates within the operating range. Compatibility with high temperatures up to 110°c

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

The Aquafen® is a high-speed floating aerator for the aeration and mixing of industrial effluent and wastewater prevents stagnation in lagoons. Provided the supply and distribution of oxygen for the treatment of wastewater. Allows the wastewater to be mixed to maintain the solid particles in suspension and ensure effective treatment of the solution in the lagoons. Designed for simple installation and can be in situ above the water surface without draining the lagoon. This aerator is used for many various applications including bioreactors, activated sludge reactors, SBRs and fixed and variable level treatment lagoons.

Fine bubble aeration system for lagoons & large surface area ponds. HDPE Floating Feed pipe sized to provide the required air flow Air supply pipe to difusers Aquatube 70 type Tubular Diffusers Stainless Steel Diffuser Feed Section Concrete ballast to stabilise the diffuser assembly Cost-effective solution Low maintenance Specific modular system Adaptable to any lagoon or large pond Low maintenance requirements Very reliable system easy to install and operate Very competitive design and scope of supply Significant mixing of the total volume within the lagoon The active biomass is aerated effectively and efficiently.

Designed for aeration of Activated Sludge Basins in Municipal and Industrial Wastewater Treatment plants. The AQUATUBE® specific design prevents sedimentation and Optimises Mixing and Oxygen Transfer. The AQUATUBE® 90 is designed to be installed on DN100 stainless steel pipe or DN110 PVC using simple fastening system. The AQUATUBE® 70 can be installed on square stainess-steel manifolds or on polypropylene manifolds. DIFFUSER BODY The manufacture of this component in glassfibre reinforced polypropylene gives it excellent resistance to abrasion, high chemical resistance, and substantial mechanical strength. EPDM MEMBRANE The Membrane prevents water from penetrating into the feeders when air is stopped. EPDM MEMBRANE The Membrane prevents water from penetrating into the feeders when air is stopped. POLYPROPYLENE FIXING BRACKETS Allows simple and easy installation on circular manifold (only for Aqua tube® 90)

Creates a mixing zone for the separation of grease and other materials. COMPONENTS Surface scrapers complete with motor gearbox IP55 – Suitable Enclosure – Painted Cast Steel Our degreaser is manufactured in stainless steel. Screen system with integrated mechanical torque limiter Integrated mechanical torque limiter Scraper arm Squeegee Stainless steel hopper for the removal of scum and other floatable materials

The EUROMIX® vertical shaft floating agitator is designed for all mixing applications and operates at 1000 rpm. The liquid rises to the surface of the tank and discharged at the base. The EUROMIX® flow-guide pipe allows the fluid to be directed to the base of the tank and can be used for deep tanks. The specific flow created ensures the mixing of the liquid. The general basis of the mixing being vertical, the water is directed at very high-speed causing a laminar flow by the agitation unit at the tank base. The EUROMIX® thus prevent the formation of dead zones in the tanks. It prevents sedimentation and rapid settling in holding and mixing tanks.
