Sludges - Import export

SYSTEM SOLUTIONS FOR SEWAGE SLUDGE DIGESTION In the municipal sector, the focus is on the production of biogas from sewage sludge. The aim is to make the energy potential of the primary and secondary sludge from anaerobic sludge digestion usable. On the one hand heat and electrical power is obtained for operation of the sewage plant. On the other hand, the sludge is conditioned so that the other aerobic process stages can run more efficiently and thus more cost effectively. The Lipp KomBio reactor has established itself as an ideal solution in the municipal sector due to its construction and long service life and has been successfully installed in hundreds of plants at home and abroad. Thanks to the application of the SBR process in our digesters, and the tank geometry and construction, it is possible to make optimum use of the low energy potential of the sewage sludge and operate sewage sludge digestion economically.

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.

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.

MSE Filterpressen® offers a wide range of filter presses with sidebar technology suitable for both standard and medium duty and for heavy-duty performance levels. Maximum flexibility is provided by choosing between simple manual to fully automated MSE filter press designs. MSE chamber filter presses are upgradable in terms of modules and features and can be customized to your specific needs and requirements. HIGH PERFORMANCE AND HIGH DEGREE OF CONFIGURATION FOR YOUR CHAMBER FILTER PRESS The chamber filter press can be configured as required depending on the series. Taking different influencing factors into account, chamber filter presses achieve a solids content in the filter cake from 30 to over 50 percent. The intelligent filtration principle leads to immense cost savings in the waste water sector, for example. The operation of the chamber filter press is designed for a feed pressure of up to 15 bar in order to successfully filter even the finest particles.

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.

Membrane filter presses have a great influence on the dryness of the solid by using membrane technology in the filter plates. Compared to conventional filtration processes, it achieves the lowest residual moisture values in the filter cake. This makes the membrane filter press a powerful and the most widely used system. IF TIME AND DEGREE OF DEWATERING ARE CRUCIAL Depending on the degree of dewatering, different dry matter contents ( – percentage by weight of dry material in filter cake) can be achieved in the filter cake by squeezing with membrane plates. The range of achievable dry matter contents extends from 30 to over 80 percent. Membrane filter presses not only offer the advantage of an extremely high degree of dewatering; they also reduce the filtration cycle time by more than 50 percent on average, depending on the suspension. This results in faster cycle and turnaround times, which lead to an increase in productivity.

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.

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).

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.

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.
