Our tubes are designed for maximal strength at minimum positive buoyancy. Although tubes are usually not as efficient as discs, tube diffusers are often the most economical choice of all diffusers, particularly the OD90mm diameter x 1 m because of their relatively large size & high air capacity compared to disc diffusers. They require fewer header pipes, less support stands and less installation time than disc diffusers. The tube membranes are extruded from low extractable oil content EPDM polyurethane, silicone or nitrile. Perforations are available in 1 mm or 2 mm slit lengths and both saddles and nipples are designed to mount to US or Metric dimension pipes.

Membrane Life Time
Up to 10 years in municipal waste water treatment plants, depending on waste water influent and operation condition.

Storage
Scogen recommends care in handling and storage to prevent tearing, puncturing or fouling of the rubber membranes. If units are to be stored before installation, we recommend utilizing the original unopened shipping cartons. Store in a clean, cool location that avoids potential mechanical damage.

Cleaning
Diffusers cleaning methods are available if the aeration tank is not behaving properly. For carbonating problem, formic acid cleaning solutions will be made available on request.

SSI manufacture AFD270 (9") and AFD35D [12"] disc diffusers with compression molded EPDM membranes. These are made with less than 10% extractable oils in the final product. Other companies may claim low extractable oil content, however SSI measures it in the final product where it tends to be higher, rather than in the base compound. Extractable oil content is important because it is a determining factor in membrane shrinkage. The less extractable oil we use to make our membranes, the less they will shrink.

Disc membranes have Die-T test results as per ASTM D624-91 of over 110 pounds/linear inch. This is double that of some competitors. Die-T measures tear propagation, which is the amount required to continue a tear. Since we perforate our diffusers with knives, Die-T is an effective means of determining the force required to tear one of our slits. Our impressive Die-T test results allow us to use more perforations in our membranes than any of our competitors. A higher density of perforations results in a more efficient diffuser.

EPDM, unlike Silicone or Polyurethane, can be compounded m hundreds of different ways, with different fillers, curvatures and percentage concentration of base polymer. SSI. together with our Malcom Baldridge National Quality Award winning membrane factory, conducted many tests and production runs before selecting our premium EPDM compound. The selection was made based on the above factors of tear resistance and oil content, but also with an eye on efficiency, which can be affected by the hydrophilic properties of the material, and on modules, which affects the "memory" of the molded product over time. Our plastic disc components are made of environmental friendly polypropylene, and are designed to seal tightly without leakage. The membrane has an integral O-ring seal which is tightly compressed by our retaining ring which keeps air in and water out. We also make viton disc diffuser for aggressive influent.

Airflex Wide Band diffusers are available in PVC plastic. They feature a clog-free design, with oxygen transfer rates of 0.5 to 0.8% per foot of submergence. They have a reliable alpha value and are designed to economically cover the tank floor. The design of the Airflex Band is longer than the typical Stainless Wide Band in the market, for good reason. It offers better floor coverage at a more economical price.

Air supply is provided by PVC or stainless steel pipes The headers serve as control for the Airflex Wide Band diffuser, removing the need for separate control, which is typical of other types of Wide Band diffusers.

The bubbles produced by this diffuser are considered medium or coarse. This diffuser is most often applied for low oxygen requirement, biological treatment, and for mixing in aerobic digesters, channels, equalization tanks, grit chambers. Diffusers available with maximum length of 800 mm long in ¾'' NPT end connection. Wide band diffusers will handle air flows from 2 m3/hr to 17 m3/hr.

THE SNAP-CAP "PLUS 5" represents a substantial advancement in the art of diffuser design The major improvement is in the snap-n check diaphragm cap which is now manufactured from a new, specially compounded, space-age EPDM based thermoplastic rubber that provides extended life and improved performance.

The Snap-Cap "Plus 5" Diffuser consists of two simple parts, the support base and a flexible snap-on check diaphragm. During aeration, the diaphragm lifts from the base, allowing the air to exit through the orifices in the diaphragm. When air stops, the diaphragm is instantly seated against the base by the pressure head of liquid, preventing back flow and clogging. The novel edge design of the diffuser locks on the removal diaphragm to avoid blow off during unusual pressure surges. Diffusers available with 3/4" NPT Threads in plastic base and stainless steel base models. Snap-Cap diffusers will handle air flows from 5 m3/hr to 17 m3/hr

Hign-Tech Low emission Marathon' burners are available in both Mono Block as well as Duo block/ Industrial designs.

The Mono block designs are available up to 15 Mw heat output loads and based on specific applications, even higher rating can be given as a single burner. The advantage of mono block design is that they are compact, all components are mounted on the burners itself and zero vibration design.

The burners and its accessories are built to suit latest CE standards and shall be capable of meeting all Safety Standards in Europe and elsewhere after DIN- E 676.

In case of dual fuel burners, the change over of either fuel is by a selector switch from the control panel only.

A very special feature of the burner system is that there is no mechanical linkage for the air to fuel ratio control like all the other burners.

Much higher turn down of 1:10 can be easily given in gas firing. Provision of Oxygen trimming / regulation and blower rpm control for reduction of power on continuous basis can be given as a standard feature on all designs/ models. Feasibility of speed regulation as well as economic advantage can be submitted prior to installation at offer stage if the operating parameters and time frame of the operating loads are defined properly.

All Marathon burners including oil cum gas type are available as regular and Low Nox [ARZ Super] version for gas operation. Oil pump with oil heating system assembled in separate compact skid for easy maintenance and trouble free operation. The oil pump offered by us is of HP Technic, Germany make.

Scogen has tied up with Neon Turibo Tech Pvt. Ltd., a leading turbine manufacturer for supply and Marketing of back pressure and extraction cum condensing turbines from 50 KW to 1.5 MW. We conduct detailed study, design, integrate the process steam, power demand, source and supply the energy efficient system with guaranteed pay back and also provide guarantee for the system performance.

Normally a pressure reducing station is used to step down the steam pressure from medium pressure without any energy recovery.. Here a simple back pressure steam Turbine can be Installed in parallel with the pressure reducing station. This combined heat and power scheme produces additional power with little or no extra cost.

We offer steam turbines that are equipped with both throttle valve controls and PLC controlled in-built safety systems, ensure trouble free operation.

Most of the process industries need both steam and power. With increasing power costs and supply shortages, the economically viable option is to go tor extraction cum condensing turbine, whereby both steam and power demand is met by a single source that is cost effective.

Our team of engineers' expertise lies in analyzing industry needs suggesting suitable systems and also implementing them in a specific time bound and cost effective way. Scogen provides consultancy to various industries in affective implementation of the system and also executes projects on total turn key basis.
