SYSTEM FOR THE COST EFFECTIVE REFURBISHING OR VOLUME EXPANSION OF CONTAINERS OR TANKS Changing conditions, material wear, a change to the filling medium – these are just a few of the factors that lead to the replacement of containers used in industry or at municipal sewage treatment plants. Quantities change and existing containers become too small – these are also problems that frequently arise. In such cases, the mobile machine technology from Lipp using the LIPP Double Seam System or the LIPP welding technique offers a solution that is as simple as it is cost effective, while being extraordinarily stable. Containers can be installed on site in any size required and can be placed in an existing steel or reinforced concrete basin using a mobile crane. The existing container volume is utilised, eliminating the need for expensive demolition work. Utilisation of the existing container volume High stability, leak tightness and safety Continuous adaptation to existing container

FOR STORING BIOMASS TO BE USED FOR ENERGY PRODUCTION OR ANIMAL FEED The LIPP System is based on a world wide unique and genuinely simple principle of tank production. Steel coils, machines and accessories are transported to the construction site, the production of the tank takes place on site – fast, efficiently and flexibly in height and diameter. In an automated, two stage process, a profile is formed from the steel strip which is joined in a second step – at the same time, the container rotates spirally. The tight and stability supporting connection of the steel band can be effected by the LIPP Double Seam as well as the LIPP Welding Technology. Compact and space saving High functional safety Reduced retention time in the digester Reduced energy losses during storage Low maintenance and durable Automatic feeding Storage losses as a result of oxidation are avoided

The self supporting, lightweight diaphragm construction made of stainless steel – with high mechanical strength and resistance to ageing – enables tanks with diameters of up to 50 m to be spanned. The stainless steel not only provides support but also seals off the tank and can withstand snow loads and high winds. The Lipp stainless steel diaphragm cover is corrosion resistant, gas and vapour diffusion tight and provides reliable protection against UV radiation and mechanical damage. The lightweight design of the diaphragm makes it ideal for covering volatile and explosive substances and prevents components from flying around in the event of an explosion. Prefabrication of the diaphragm at the factory eliminates the need for welding work to be carried out at the construction site.

ON SITE PRODUCTION FLEXIBILITY WITH CONTINUOUSLY VARIABLE DIMENSIONS Special circumstances and requirements often call for containers which cannot be produced using standard solutions. This is where special tanks and silos which can be adjusted to suit prevailing conditions and provide individual solutions are required. The LIPP System offers a variety of possible solutions to a wide range of problems in the form of welded or folded designs. Steplessly adjustable diameters and heights enable tank dimensions to be individually adapted to the prevailing conditions. In addition, on site installation only requires a minimal amount of space, for example enabling containers to be constructed in buildings or other situations where there is limited space available. Tank in tank solutions can also be realised using the LIPP System. Tank in tank solutions Container expansion, e.g. of concrete containers Installation inside buildings Mounting on platforms Mounting on various substructures

LIPP understands that adaptability provides solutions for various applications and requirements – so customers can even specify their own services to lower the total cost of investment.

With such flexibility, the sales team at Lipp can enable any customer to specify exactly what is needed for their installation. From complete, turnkey systems to individual components and accessories – Lipp can support customers whatever their requirements. Consultation is a primary objective for Lipp before any work is undertaken. Lipp provides diagnostic tests, efficiency calculators and flow sheets to visualise a tank system and inform the customer of the performance they can expect. This is especially useful for anaerobic digestion – where Lipp experience supports the efficiency and safety of the system from design through to construction. Particular attention is always paid to the content to be stored within the storage system, which allows Lipp to offer customers the chemically stable materials and accessories to get the most from their storage tanks and digesters. Fundamentally, Lipp’s focus on the customer allows consultation and sales to be perfectly integrated

Lipp systems are modular and can be extended, modified or integrated into existing systems WITH EASE. Biogas plants from Lipp are based on the so called, wet fermentation. Through a 2 stage process, i.e., via regulation by an upstream hydrolysis stage or other substrate pre treatment, input materials are prepared so that the anaerobic process can run optimally in the digester. Since it is the most flexible and the biological processes are best kept controllable Lipp favours the SBR process. This is also particularly suitable for anaerobic wastewater treatment, sludge digestion and is also used in agricultural biogas deposits. This means first that Lipp biogas plants are substrate flexible and allow an intensive use of the available digester area. Secondly, that with low self sustaining energy requirements, a high degradation rate is achieved. It is interesting to note that Lipp’s digester can be operated not just in the SBR process (Sequence Batch Reactor).

BIOGAS FOR INDUSTRY, MUNICIPALITIES AND AGRICULTURE In addition to tank construction, LIPP built the first biogas plant in Germany in the 70’s. Furthermore, LIPP was one of the first companies to develop and sell small biogas plants in the early 80’s. By steady advancements in production technology and the materials used, as well as extensive experience in process engineering LIPP has installed in collaboration with its partners, hundreds of biogas plants in Germany and worldwide. The majority of these projects are still in operation and ensure proof of the high quality and the technical and economic performance of Lipp’s system solutions. LIPP provide system solutions for biogas production in the following areas APPLICATIONS anaerobic wastewater treatment plants waste fermentation plants sewage sludge digestion agricultural biogas plants

SYSTEM SOLUTIONS FOR THE STORAGE OF CEREAL PASTE AND SUGAR BEET Lipp plans and sells storage systems for biomass such as cereal paste or sugar beet under the brand names LIGAVATOR and BETAVATOR. These systems are generally gas tight and both roof and container base (optional) are made of solid stainless steel, since the stored media can give rise to very aggressive juices and gases. With this type of storage the substances are preserved and can be used over a very long period. Automatic withdrawal and substrate delivery can also be installed in the following systems by an appropriate control system. APPLICATION EXAMPLES AND REFERENCES In addition to pure crop storage, the Lipp LIGAVATOR / BETAVATOR systems are mainly used as substrate storage for agricultural or industrial biogas plants, and are installed before the fermenter for appropriate substrate supply. They allow largely automated control of a biogas plant, as there is no need for a regular manual substrate supply.

OVER 45 YEARS’ EXPERIENCE IN AGRICULTURAL BIOGAS PLANTS When deciding on a biogas plant, the manufacturer’s experience should be prioritised. It is not just a question of economic viability, but essentially of optimal design. Lipp GmbH has over 45 years’ experience in this area and is continually developing the technology. The biogas plants manufactured by Lipp are based on a rounded plant concept in terms of consulting, development, manufacture and assembly. With its comprehensive expertise and the use of proven technologies such as the Lipp dual seam system, the material Verinox, and high quality accessories, the highest level of quality is achieved with optimum economic efficiency.

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.

Lipp tank and system solutions for municipal waste water treatment have been realised in close cooperation with well known design companies and end customers since the 1980s. In addition to municipal waste water treatment plants in Germany, Austria, Switzerland, France and other European countries, the Lipp system has already been successfully installed in many Asiatic projects. Lipp waste water tanks are offered in variable sizes and with individually adapted features (material, covers, additional equipment). Our success lies in professional management and close cooperation with all stakeholders over the entire project period. Reliable tank solutions, timely installation and numerous reference plants both in Germany and worldwide make Lipp an important partner in municipal waste water treatment.

As well as the high quality, end customers and engineering offices alike appreciate Lipp’s process expertise and close, professional working methods. In addition to individual planning and timely installation, the service package is also rounded off by extensive tank inspections. Depending on customer requirements, Lipp offers its partners support in the preparation of necessary planning criteria such as design, heat and energy calculations etc. Lipp’s objective is to be the most reliable partner for municipal sewage treatment plants and for engineers for municipal waste water treatment and sludge digestion. To achieve this, in addition to the product quality, the professional, timely and economical completion of projects is constantly being improved. In order to work with end users and engineering offices as effectively as possible, the technical process expertise is also being constantly expanded by the ongoing qualification of employees and high investments in research.

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.
