3 -2-1. SHIPMENT, STORAGE, AND HANDLING 1.1. Shipment Description Lantec media are usually shipped to location by contract motor freight trucks. Standard shipping containers are corrugated cardboard boxes containing 6 cubic feet of HD Q-PAC each. Boxes are generally checked for damage by warehouse personnel prior to shipment. It is imperative that customers check delivered goods upon arrival, as damage during shipment should be noted on the bill of lading at the time of receipt Storage and Handling Plastic media are shipped in cardboard boxes which are not designed for outside storage. Care should be taken when handling to prevent boxes from tearing open or corners from being crushed Inside Storage of Standard Boxes 1. Stack boxes on wooden pallets or on level floor so that there is no danger of water damage. Make sure the entire bottom surface of each box is fully supported. 2. Do not stack boxes more than three high or tape boxes together as a group. If the media is to be stored in a climate with high humidity (90% or more) for an extended period of time, then reduce the stacked height to two boxes. 3. Do not put any load on top of stacked boxes. Never allow any person to climb on or store other equipment on top of any of the boxes Outside Storage of Standard Boxes 1. Outside storage of standard boxes is not recommended; however, if not other alternative is available, follow recommended stacking of two boxes high max. 2. Completely cover boxes with weatherproof canvas or plastic. It is important that air can circulate among the boxes so that condensation does not form on the inside of the cover. 3. Boxes of media stored outdoors will not support any load. Make sure that rain water, ice, or snow do not build up on the top of the covered boxes.

4 2. INSTALLATION INSTRUCTIONS General Information HD Q-PAC is delivered in blocks of 12 x 12 x 12. For some vessels, HD Q-PAC may have to be inserted through manways. Such manways must be large enough to pass a full 1-cubic-foot block. Extreme caution must be taken when workers are present in the vessel installing the media make sure that the media support can withstand the combined load of the media and the workers. When its grids are oriented vertically (see below), HD Q-PAC is rigid enough to be walked on, and can be traversed as a platform for installing the next level of blocks, so long as the support plate can withstand the force mentioned previously. It may be helpful to lay plywood on top of the HD Q-PAC media as a platform; this will prevent dirt and debris from being lodged in the media openings when workers are walking on it. Finish all welding or other work that produces sparks prior to installation of any plastic media. 2.2 Installation Procedures 1. HD Q-PAC is designed to be installed in a structured, block-byblock manner. Each block occupies a 1 ft 1 ft cross section. In cold weather (below 45 F), care should be taken when handling and installing plastic media, since the plastic material will be more brittle when cold. 2. For installation in vessels that are not rectangular (e.g., round or oval), HD Q-PAC blocks can be cut to size. Plywood jigs can be cut to the shape of the vessel at hand, then pieces of HD Q-PAC can be sandwiched between the jigs and cut to size with a largethroated band saw. Vessel layouts are available upon request. 3. When it is desired to maximize the liquid holdup on the media, HD Q-PAC should be installed with the grids oriented horizontally and the short rods pointing downward. It is best to support the media on thin bars that fit between the short rods, so that the plastic grid rests directly on the media support. If the HD Q-PAC is supported on a few of the plastic rods, it will be more susceptible to tilting during and after installation. Rods facing downward

5 -4- If it is desired to maximize the flow capacity of air and water through the media, HD Q-PAC should be installed with the short rods pointing sideways. If multiple layers of HD Q-PAC are stacked one atop another, alternating layers should be rotated 90 with respect to each other. For example, if the first layer is installed with the rods pointing north, the second layer should have rods pointing east or west, the third layer should have rods pointing north or south, and so on. HD Q-PAC blocks should fit snuggly together, but need not be attached or connected to each other. 4. Check the position of any sensors that may extend into the media. Be careful not to bump sensitive process measurement devices with the HD Q-PAC blocks. 5. The HD Q-PAC blocks, if properly installed, should appear level upon completion. 6. Before completing the media installation, consult the installation procedures for bed limiters, liquid distributors, and other internal components to see if partial installation is required before media installation is completed. 7. Take care not to leave any foreign matter in the packed bed section of the vessel. Make sure all boxes and bags are removed. 8. If procedures are not clearly understood by the personnel installing the media, they should call the media manufacturer for additional information. 3. OPERATION AND MAINTENANCE 3.1. Operation Operation of the vessel should be in accordance with the procedures outlined by the vessel manufacturer and according to the design specifications Maintenance and Cleaning The media should be inspected on a regularly scheduled basis. Past experience indicates a minimum inspection period of six (6) months to check for excess fouling. The optimum inspection time will vary from area to area depending on the type and rate of for-

6 -5- mation of deposits from your water source. The best media cleaning procedure will depend on the type and amount of fouling (collected deposits such as iron compounds, carbonates, and bacteria) that has accumulated on the media. The media can usually be cleaned in place if fouling is not allowed to become excessive. 4.
