Gas storage systems by Lipp have been successfully installed in more than 300 projects in Germany and worldwide. The gas storage capacity extends from 30 to 5,000 m³. The gas resistant PVC gas holder is protected by a galvanised steel cylinder. The self supporting roof is made of 1.4301 high grade stainless steel. The Lipp gas holder is offered as a complete system, including sensors and built in parts as well as steel construction, and can be easily integrated into an existing system. The main area of application of the Lipp gas holder is municipal waste water treatment plants and landfills which want to balance out fluctuations in gas production and at the same time need a buffer store for possible downtimes. A further gas holder may also be of interest for direct marketing of biogas, where feed in at certain times is necessary. The Lipp gas holder is especially attractive when considering the fact that electricity cannot be stored. But (bio) gas, which is used for power generation

SYSTEM SOLUTIONS FOR GAS STORAGE With the Lipp gas holder Lipp offers a tried and tested system solution which is complete in itself, for unpressurised storage of biogas, sewage gas and landfill gas. This solution is chiefly used for municipal waste water treatment plants and landfills. Due to its design, as well as high functional and operational safety, it also ensures low maintenance costs over a very long service life. This is mainly because the sensitive gas holder is protected against UV radiation and other environmental influences by a steel container manufactured with the Lipp dual seam system. Furthermore, this construction method allows an exact leak test and highly accurate metrological monitoring of the gas fill level. Both aspects are essential for safe and efficient plant operation. With certification according to § 19 WHG for Lipp GmbH and DVGW approval of the gas storage tank, further conditions are met for use in municipal waste water treatment plants.

ATMOSPHERIC PRESSURE, MAINTENANCE FREE AND PROTECTED AGAINST EXTERNAL EFFECTS The pressureless gas storage system of Lipp is used for the storage of gas produced on landfill sites, waste water treatment plants and also as external storage on biogas plants. The system is determined by its robust and technical advanced construction where the gas balloon is protected by a galvanized steel tank. This protects the balloon against UV light and also other external factors. The system is mostly utilized at landfill sites or WWTP to buffer the gas before its further processing. The experience gained during the past decades has improved the complete system and the single components and makes it a perfect choice for end users and general contractors.

Landfill leachate treatment Landfill leachate must not be leaded to the canalization or the recipient untreated. According to the guidelines of environmental protection, waste water hast to fulfill limit values of introduction and reusable water has to be cleaned and separated to be used as process water or maybe as drinking water. So, also landfill leachate – as many other industrial waste waters, too – has to be treated in a way, that introduction into a downstream sewage plant or recipient is according to the law. The multitude of ingredients of the landfill leachate has to be concentrated as much as possible, so that they can be bailed compact and without negative results for the environment. For the treatment of landfill leachate we offer the following processes of conditioning: Treatment of the leachate to reach recipient quality and concentration of the remaining ingredients in a way, that they can be leaded back to the landfill considering the water balance.
