WASTE TO ENERGY INDUSTRY BIOGAS FROM ANAEROBIC WASTE WATER TREATMENT AND WASTE FERMENTATION PLANTS. Due to their technical characteristics and profitability, Lipp tank and system solutions are used in a variety of industrial biogas plants. Two areas of application can be distinguished, which in many cases also follow both objectives. APPROPRIATE PROCESS TECHNOLOGY, SUITABLE CONTAINER TECHNOLOGY AND THE RIGHT DIMENSIONSFirst, the anaerobic treatment of various industrial waste waters, such as in food production, biofuels or similar. The main objective here is the anaerobic pretreatment of highly contaminated but easily degradable waste water to reduce the COD load before it can go to the next stage of aerobic waste water treatment. The challenge is that in spite of the low DM content, a high degree of degradation is achieved by biomass retention or return and at the same time, biogas is produced. Due to the flexibility and variability of the Lipp system in terms of procedures

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.

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

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

Condensate polishing During the production process of basic organic chemicals, very often condensates occur as byproducts, which have to be treated before dumping or recycling into production process. The condensate occurring at the product process of caprolactame contents for example ammonium sulfate and caprolactame. The loss of these products instead of recycling would not only mean a reduction of the process recovery, but also very high costs for waste water treatment. These condensates can be concentrated by a reverse osmosis plant. Because of the high salt retention rate of the reverse osmosis membrane, nearly all contents of the condensate are separated and can be brought back to the production cycle. The filtered permeate can be dumped into the municipal waste water system without hesitation. In some cases, the recirculation of the separated contents is not appropriated. In this context, reverse osmosis helps reducing the volume of the accruing condensate. The remaining conden

MSE stainless steel filter presses comply with the high hygiene and purity standards both in design and processing. With the stainless steel filter press, all components in contact with the product are covered with high-quality stainless steel. This also provides optimum protection against corrosion. FDA-COMPLIANT SOLID-LIQUID SEPARATION WITH THE MSE STAINLESS STEEL FILTER PRESS A large number of materials with different properties are used in the food sector in particular. Here, especially care must be taken to ensure that no ingredients are released into the food. The law stipulates a FDA certification for this. Accordingly, all materials used must be FDA-certified. The FDA certification stands for high purity and durability. Each component such as the filter plates, filter cloths and piping systems complies with the FDA guidelines. This contributes to high hygiene and safety requirements.

The hot filter press combines the standard process steps of a membrane filter press, (filtration, filter cake washing and squeezing), with the additional function of a thermal filter cake drying (TCD). As a result, all process steps are carried out in one plant, the hot filter press. Dewatering and drying of the resulting filter cake is thus done without a downstream drying process. Cost-intensive and time-consuming vacuum contact drying is therefore no longer necessary. FUNCTIONAL PRINCIPLE OF THE HOT FILTER PRESS – WITH THERMAL FILTER CAKE DRYING In contrast to the conventional method, the system consists of membrane filter plates and heat exchanger plates, which are installed alternately in a filter press. For thermal drying, hot steam and/or oil is applied to the working space behind the membrane and the filter cake is thermally dried accordingly. The advantage of this process is that a high dry matter content (DM content) of over 90% is achieved.

Based on the decisive properties of the flexible material, the rubberised filter press is mainly used for the filtration of particularly aggressive suspensions and environments. The aggressive suspensions include, for example, solvents or acids. In this context, the conventional painting of the steel parts is no longer sufficient. THE RUBBERIZED FILTER PRESS OF MSE AS PROTECTIVE MEASURES AGAINST AGGRESSIVE SUSPENSIONS In a complex process, the load-bearing filter press components are coated with a layer of 3mm thick plastic. In the case of the rubberised filter press, the hydraulic stands, feed stand, pressure plate and supporting beams are hard rubberised and the smaller components are made of polypropylene. It is also possible to rubberise only the components in contact with the product, such as the feed stand and the pressure plate. The composition of the rubber coating depends on the special surface requirements of our customers.

With its structural protection measures and its specific requirements the ATEX filter press complies with the ATEX directives. As a result, these types of filter presses are designed for a high level of safety and explosion protection. ATEX „ATMOSPHÈRES EXPLOSIBLES„ ATEX derives its name from the French term „ATmosphères EXplosibles”. It consists of two EU directives governing explosion protection and thus the equipment and working environment in an environment with an explosive atmosphere. ATEX filter presses are especially used in filtration processes in the chemical, petrochemical, oil and gas extraction, mining, food and waste water sectors. With their design, as well as the selected materials, they comply with all the requirements of the ATEX certification in potentially explosive areas.

Especially in rapidly changing markets, it is all the more important to rely on a partner with many years of market and expert knowledge. With semi-mobile container plants – similar to mobile filter presses – we support you in defying the rapid changes on the market in order not to jeopardise your core business. Semi-mobile filter presses can be used flexibly and are also quickly ready for operation. Furthermore, the semi-mobile filter press is fully equipped and immediately ready for operation after connecting to sludge, water and power supply. MSE Filterpressen® engineers and manufactures the plants for individual customer requirements. In this way, the best possible result can be achieved for every task. The semi-mobile filter press from MSE is available in various designs. The sizes of the semi-mobile filter presses are available up to a maximum size of 1500 format. This corresponds to about 100 chambers, i.e. about three cubic meters of chamber volume.

CellTRON® FOR MAXIMUM FILTRATION REQUIREMENTS The basis of this plant is a membrane filter press. The new product series is equipped with an innovative filter press emptying system with lifetime error message, an automated filter cloth washing system with implemented CIP cleaning function as well as an automatically opening and vacuum-proof housing. In contrast to conventional filter presses, this new development guarantees an almost gastight encapsulation of the filter press. The filter press thus meets the specific requirements for dewatering special (metal) sludges. In addition to standard configurations for battery cell production, this technology series is also suitable for demanding applications that require the highest safety and efficiency standards. These include volatile, dust explosive products as well as substances with toxic and radioactive properties but also pharma food products and hot suspensions (≥130°C).

Semi-automatic filter presses represent a simplified and cost effective solution for the reliable operation with respect to operation and safety measures. This type of filter press is distinguished by a special, a rail-mounted two-hand control panel. The filter press with two-hand control is used in particular when the space on site is limited or a higher degree of automation is not required. Accordingly, a conventional version of the protective device is no longer effective. REDUCED PROCUREMENT COSTS AND SIMPLE OPERATION – THE SEMI-AUTOMATIC FILTER PRESS WITH TWO-HAND CONTROL FROM MSE Based on the safety technology requirements, an intelligent two-hand control is implemented, for example, for moving the filter plates by means of automated plate shifter. This functional principle thus prevents the operator from reaching into the working area. Complicated mechanical designs including further safety measures are not necessary.

Fully automatic filter presses are specifically designed for applications in which a continuous operation and fast cycle times are essential and therefore crucial. MSE fully automatic filter presses provide a high degree of automation while providing uninterrupted operation at the same time. FULLY AUTOMATIC FILTER PRESSES FROM MSE INCREASE PRODUCTIVITY AT THE SAME TIME REDUCING PERSONNEL COSTS The operating time of a fully automatic filter press is 24/7. The option of the simultaneous filter plate opening system, for example, helps to realise a particularly fast cake release reducing the cycle time to a minimum. The result is a high-speed filter press that allows increased production per unit area of filter. For this reason, these machines are used in applications with highly filterable products where high filtration speeds are required. These include, e.g. mining concentrates and residues.

Mobile filter presses are particularly suitable for dewatering sludge from several plants at regular intervals or for compensating capacity peaks and bottlenecks. The fact that mobile filter presses are not subject to approval obligation and are therefore quickly and unbureaucratically available is particularly interesting. MSE mobile filter presses are fully equipped and immediately ready for operation after connection of the sludge, water and power supply. In this way, the best possible result can be achieved for every task. Mobile filter press plants can be implemented in many different designs. The sizes of the mobile filter presses are available up to a maximum size of 1200. This corresponds to about 100 chambers and about three cubic meters of chamber volume. The plants are equipped with suction and pressure-side inline mixers. The PLC plant controls the conditioning parameters in proportion to pressure and/or volume.
