    1. Aeration System

    This manual gives a detailed description of installation and operating of the tube diffuser JetFlex TD 63 /2 with the perforation lengths 1000 mm, 750 mm and 500 mm (39.4, 29.5, 19.7).

    2. General

    Jger Umwelt-Technik GmbH & Co. KG Aeration Components delivers aerating systems for applications in aeration basins in communal and industrial waste water treatment plants. The aerating systems are intended for fine-bubble compressed air ventilation of activated sludge in biological waste water treatment. With membranes made of EPDM-rubber an intermittent operation is possible due to the long-term elasticity of the membrane material.For applications in industrial waste water treatment plants and/or in communal plants along with more than 10% industry share please consult Gummi-Jaeger regarding suitability of membrane materials. Quality properties of materials, perforation and bubble size/uniformity are controlled and recorded generally. The aeration systems are delivered completely assembled. Jger Umwelt-Technik GmbH & Co. KG Aeration Components recommends a careful treatment of storage, transport and installation, to avoid damage of the membranes. The Jger Umwelt-Technik GmbH & Co. KG General Conditions of Sale are valid in their new version, respectively.

    3. Shipment

    We ship diffusers in cardboard boxes. See individual data sheets for packaging details.

    4. Incoming Inspection

    Upon delivery check packages, equipment and products for structural damage during shipment, par-ticularly the rubber membranes and stainless steel clamps. Any damages of packages, equipment and products must be reported to Gummi-Jaeger Aeration Components and shipping agent within 5 work days of delivery. Jger Umwelt-Technik GmbH & Co. KG reserves the right for damage inspection. Warranty takes place only for original and unharmed packaging.

    5. Storage of Equipment

    Store equipment and diffuser as well as all accessories in their original packaging in a dry and aerated room regarding to DIN 7716. Prevent from frost, excessive heat, direct sunlight, dust, mineral oils and hydrocarbons. Avoid works which can lead for the damage of the aerators and their packaging. Do not store outdoors! Storage time of rubber parts up to the installation / starting operation should not exceed 1 year. At on-site delivery, all rubber and plastics parts must be stored in their original packaging. Crates exposed to direct sunlight must be covered with tarpaulin to protect against UV-radia- tion. Do not use packaging material containing plasticizers.

    6. Assembly

    6.1 Preparations

    Prior to assembly of the aeration systems pipings and basins have to be cleaned of all pollutions like stones, wood pieces, etc. As lateral should be used high-grade stainless steel square tubes with dimensions of 80 x 80 mm or 100 x 100 mm. Using standard PVC (Schedule 40 or 80) or stainless steel pipes DN 100 (114.3 mm / 4.5) as laterals special round tube adapters are necessary . Air distribution through JetFlex TD 63/2 tube diffuser is a function of individual diffuser elevation. For proper system operation all lateral pipes must be levelled within a tolerance of 0,6 cm / 1/4. The use of 1 double nipples requires a lateral piping with predrilled and tapped outlets with a diameter of 34 mm / 1.34 aligning on horizontal axis with a tolerance of 0.5 mm / 0.02. The use of 3/4 double nipples requires predrilled and tapped outlets with a diameter of 27 mm / 1.06 aligning on horizontal axis with a tolerance of 0.5 mm / 0.02. Outlet holes may not lie in the weld area. Contractor is to confirm the cleanliness of the air piping. Corrosion damages (rust) are to be eliminated. Air purge or water flush cleaning is recommended prior to diffuser installation to remove any internal debris and tailings that may have accumulated in the header piping.

    6.2 Diffuser Alignment

    Align the main flow directions of waste water along the diffuser longitudinal axis. Particularly for the JetFlex TD 63/2100 D this leads to a reduction of the oscillation load. Choose a minimum distance of accelerators to diffusers and a maximum velocity of flow around the diffusers does not exceed 0,5 m/s.

    6.3 Diffuser Installation

    1. For easy installation the EPDM flat-gaskets can be moistened with a lubricant. 2. A commercial grade water-based soap (concentration 5% - 10%) is recommended as lubricant. Lubricants containing mineral oils or hydrocarbons are not allowed.3. Thread the stainless steel double nipple into the diffuser and put on the flat-gasket (or the special round tube adapters).4. Place the free end of the double nipple through the outlets of the lateral pipe and put on the second flat-gasket (or adapter). Thread the second diffuser onto the double nipple.5. Hand tighten both diffusers by rotating clockwise. Tighten both units an additional 1/2 to 3/4 turn with 2 fork wrenches contacting at the across flats. DO NOT OVERTIGHT- EN. Adjust the across flats horizontal for both diffusers with a tolerance of 10 (see sketch). Now the perforated area
