1 Liquids purification by MECHANICAL PARTICLE SEPARATION 1

2 Making the world a little cleaner Läckeby Water Group is committed to helping society and industry provide a healthy and sustainable environment. We build plants and equipment to purify drinking water, waste water and industrial process water. We construct plants to extract and upgrade biogas from all types of compostable waste and we effectively use the excess heat from our processes. Quite simply, we make sure that the biproducts of human activity are taken care of in a responsible manner. Läckeby Products Läckeby Products develops and manufactures high quality products for mechanical particle separation. Our range of drum screens, classifiers and decanters are state-of-the-art and designed to reliably mechanically separate particles from liquids. We specialise in the first stage of the cleaning process. The robust designs and unique technical solutions ensure that sludge and particles are effectively and cost efficiently separated. Further down the cleaning process, valuable and sensitive membrane equipment is effectively protected from abrasive particles. The result? Greatly improved water quality. Experience and know-how Since 1965 Läckeby Products has designed, built and installed thousands of high quality mechanical separation products in a wide variety of industries and applications. Today, we draw on this vast experience to continue developing the most effective pieces of equipment for your needs.

3 Mechanical particle separation Our products for effective liquids purification are found in demanding applications such as water purification plants, waste water treatment plants and in a wide variety of industries around the world. Liquids/solids separation There are no limits to where our mechanical liquids/solids separation products can be of benefit to you. The obvious applications are potable water and waste water treatment works. Other applications are mostly found in the food processing industry where we help clean process water in restaurants, slaughter houses, fish processing plants, breweries etc. Important applications are also found in industrial processes such as textile mills, chemical plants and in the pulp and paper industry. Potential for large savings Today, there is increasing pressure on industry to pay a high price for processing waste water. Consequently there is potential for cost savings in managing process water on site. Custom designed drum screens, classifiers and decanters from Läckeby products effectively clean process water and allow it to be recycled into the process again. This results in large long-term cost savings. 3

4 World beating water purification products Why should you choose water purification equipment from Läckeby Products? Because they are robust, service proven in the toughest of environments, and because they can be custom designed to your specific needs. Drum screens Our Roto-Sieve drum screen is principally built up of a rotating perforated drum with an internally mounted screw that transports the separated solids out of the drum. The drum screens come in five different sizes to allow for different flow requirements. The capacity depends on drum dimension, drum speed, hole size, flow speed, degree of pollution and type of polluting agent. Approximately custom designed drum screens are installed at industrial plants and public works throughout the world. When reliability counts Läckeby Products liquids/solids separation system are built to last. Robust construction and low maintenance requirements provide extended availability and excellent production economies. Classifiers Classifiers from Läckeby Products are designed to separate sand and other types of sedimentary particles. The robust, stainless steel classifiers are built for maximised dewatering and minimised maintenance. More than 100 classifiers are installed at industrial and municipal plants.

5 Decanter Decanters Virtually maintenance free, the decanters from Läckeby Products are designed to float in waste water settlement tanks. Cleaner top water flows into the decanter through evenly distributed holes, just below the surface, and is then discharged to the next phase of the treatment cycle. This unique solution is based on gravity and pressure differentials, eliminating the need for traditional pumps and valves. Decanters from Läckeby Products are installed in a wide variety of industrial and municipal water treatment plants. Infrastructure Läckeby Products manufactures and installs all necessary infrastructure to make your liquids purification plant as efficient as possible. We offer a complete range of shaftless transportation spirals, transportation screws, shaftless screw presses and storage bays. This is a complete solution from one responsible supplier.

Installation and service Naturally, Läckeby Products ensures efficient installation and commissioning of each mechanical particle separation product. In addition we offer a comprehensive service programme including monitoring, technical support and upgrading. Stainless steel, shaftless transportation spiral 5

6 Cleaning and recycling Almost everything man does creates waste. The purpose of our products is to purify to allow recycling and reuse. Waste water treatment The entire Läckeby Products product portfolio can be effectively used in waste water treatment plants. Depending on the content and volume of the waste, we help optimise complete solutions to cost efficiently and reliably improve water quality. Don t forget that we also offer total service and maintenance packages to ensure high quality operation. Industrial process water treatment For many process industries good water quality is a key production factor. Interestingly it is possible for process water to be cleaned and reused over and over again. These closed-loop systems are very cost effective long term solutions. Please contact Läckeby Products for custom designed water treatment products that will help your sustainability credentials. Industrial liquids purification For industries such as slaughter houses, food processing, fish processing and breweries it is often commercially advantageous to perform primary treatment on site. The cleaner the water discharged into the municipal waste water network the lower the treatment cost will be. And don t forget, our products can be used to purify liquids such as oils, lubricants and cooling agents. We help you design purification solutions that suit your exact requirements. Raw intake water Even the best raw ground water needs purification. The drum screens from Läckeby Products ensure that the larger sand particles and impurities are removed. 6
