| For aeration and mixing activated sludge, incorporates an open non-clogging impeller. The unique design eliminates rag build up that can result unbalanced operation. To assure a long life of trouble-free operation each aerator is fabricated on a special jig fixture and is dynamically balanced prior to shipment. The aerator can be mounted on a bridge, platform or floats. As it rotates, liquid is drawn up along the blades and then flung outwards in a low trajectory with a minimum loss of energy. Air is drawn in behind the blades and mixes with the liquid in the region of greatest turbulence. The blades disperse the liquid over a large surface area, thus entraining more air. The action coupled with the displacement of the liquid creates a powerful vortex-like motion that causes more liquid to rise from the bottom of the tank, thus creating a continual aeration cycle involving the entire tank volume. It is a reliable machine providing aeration and mixing in numerous applications: | |

The company is capable of turnkey design, construct, install and commissions of oxidation ditch activated sludge treatment system operated in extended aeration mode; is a single stage nitrification biological treatment system. Oxygen is transferred from the atmosphere to the mixed liquor using vertically mounted slow speed aerators to achieve oxidation, nitrification and phosphorous uptake. The aerator is positioned at the turn of the racetrack and is aligned with the center wall between the channels, operating at a speed to assure adequate channel velocities are maintained within the ditch. The slow speed vertical aerator is capable of oxygen transfer efficiency at 2.1 kg O2 input / kWh. The turnkey project from concept to complete construction and commissioning of the Treatment Plants; includes the operation, renovation and maintenance of the main pumping stations. The Company employ professional project managers, engineers, superintendents, foremen and key personnel. This ensures that every project is staffed with experienced competent people and is meticulous in allocating experienced and qualified personnel to each of its Contracts. |  |

Submersible Mixer / Aerator These are self-aspirating submersible mixers / aerators, with motors from 1.1 to 18.5 kW and a specially designed venturi system. It is very a simple and effective system for mixing and aeration of wastewater and other liquids in deep tanks. Application possibilities are mixing / aeration of wastewater, drinking water, fish ponds. Air injection and mixing of chemicals in equalisation tanks. |  |

This has significant improvement over the conventional DAF systems. It has special air induction system that uses the multistage Centrifugal pump to pressurize and let the air dissolved into the liquid. It does not use air compressor, pressure dissolve tank, ejector and static mixer that makes the system small in size and competitive in price. This system is up to 10 times more efficient in producing the right size micro-bubbles for flotation, and is simple to operate and maintain. Solids formed during the coagulation process are removed by the micro bubbles floating the solids to the surface, and are skimmed away by mechanical scrapper. It removes completely both suspended and precipitated matter in raw waste liquids, produces effluents that need no further clarification and the floated sludge need no further dewatering. The resulting clarified effluent is free of suspended solids. Dissolved air flotation is an excellent treatment solution for water having high levels of algae and other low-density particles that cannot be removed efficiently and effectively with sedimentation. The DAF system is suitable for many applications, including low turbidity (<100 NTU), textile wastewater with high color and TOC, filters backwash applications and includes: |   |

A high-rate treatment plant in a single basin that employs the principle of internal slurry recirculation provides effective clarification in municipal or industrial water and wastewater applications.

High-rate solids contact clarifier combines optimized flocculation, internal and external sludge recirculation, to achieve very high hydraulic loading and treatment efficiencies. It is effective for lime softening of ground or surface waters, tertiary treatment of wastewater, and precipitation of metal hydroxides from waste streams. It can accommodate a wide range of flow rates and solids variations.
