1 Introduction Congratulations on choosing CERAFILTEC’s ceramic membrane module. The CERAFILTEC system is a highly sophisticated product. We strongly recommend using only trained and experienced technicians for assembly, installation and troubleshooting. To locate the closest authorized service technician or to request an assembly training please contact your CERAFILTEC representative or visit website at http://www.cerafiltec.com/team/. If you decide to install the equipment yourself, please follow this assembling manual. For installation assistance, contact your CERAFILTEC representative. You will ensure a successful installation as well as reliable operation by carefully reading this manual and following the operational guidelines. Convince yourself about the easy assembling. Under the following links we show you demonstration videos of assembling and operation references: http://www.cerafiltec.com/how-to-assemble/ http://www.cerafiltec.com/videos-processes-references/ This document contains general guidelines. Depending on the application and project specific installation requirements, e.g. how many modules per tower to be assembled, construction of accessories inside the filtration tank, like position holders, aeration and sprinkler sets, hose connections of tower, main filtered water header, and other need to be considered. Please follow these additional instructions, listed in the project design and execution documents. If you do not have the project design or execution documents, please contact your CERAFILTEC representative. Please contact your CERAFILTEC representative or check on website http://www.cerafiltec.com for any further manual updates to insure correct and safe assembly and installation. 2 Technology and Product Introduction 2.1 Filtration classification, applications and removal targets CERAFILTEC’s filtration module is a chemical and temperature resistant Ultra-Filtration (UF) ceramic membrane filter for solid-liquid separation. It can be used in various sources of contaminated water. The technology is well used in the following applications: ▪ Drinking water from ground- and surface water sources ▪ Brackish water and seawater reverse osmosis pre-filtration ▪ Municipal and industrial wastewater treatment ▪ Mining wastewater treatment ▪ Oily wastewater treatment ▪ Produced water treatment ▪ Scrubber wastewater for marine scrubbers ▪ Recovery of backwash wastewater from sand filters ▪ Sludge thickening of activated sludge ▪ Hot water filtration ▪ Others challenging industrial waters With an average filter pore size of 0.1 micron the UF membrane acts as a physical barrier to removal any suspended solids from the water, like: ▪ Sand particles, silt and colloidal silica ▪ Metal oxides, like iron and manganese oxides ▪ Pollen, Germs and bacteria ▪ Algae ▪ Oil and grease ▪ Colloidal fractions ▪ Chlorinated diphenyl ▪ TEP (Transparent Exopolymer Particles) ▪ EPS (Extra polymeric Substances) ▪ Others Ultra-filtration technologies with a pore size of 0.1 µm are commonly understood as filtration solution to remove suspended solids such as clay and silt, pollen, algae, precipitated metal oxides as well as fractions of colloids. They are also a physical barrier for germs and bacteria and are classified as disinfection solution with typical log removal value (LRV) above 5.

CERAFILTEC’s ceramic flat sheet membrane solution is more than just a common ultra-filtration. In conjunction with developed pre-treatment processes, e.g. active cake layer filtration for a selective removal of dissolved ions, CERAFILTEC provides a superior filtration solution. Therewith, only CERAFILTEC achieves unprecedented filtered water quality, and consequently being the best prefiltration solution for all NF and RO applications. The technology is typically used as pre-filtration for desalting technologies, like Nano-Filtration and Reverse Osmosis. CERAFILTEC’s filtration module is highly seawater resistant and corrosive free. http://www.cerafiltec.com/classification/ 3 Ceramic Flat Sheet Materials The CERAFILTEC module housing can be used with a wide variety of ceramic flat membranes. The module housing of CERAFILTEC is the standard and the different ceramic membranes can be used specifically according to the application. The ceramic plates marketed by CERAFILTEC have different properties depending on their choice. Please refer to the manufacturer's instructions for the membranes. 3.1 Ceramic Membrane properties The high resistance of ceramic materials and the resulting cleaning possibilities generate a unique highperformance system. Depending on the medium and the operating conditions, mechanical, thermal, and chemical cleaning strategies it can be combined individually to achieve a stable and low maintenance long-term operation. 4 CERAFILTEC´s Ceramic Membrane Module One module is a single, modular and expandable filtration unit consisting of a glass fiber reinforced plastic housing and the flat sheet ceramic plates. The module housing was developed to tightly transport the liquid medium in internal channels, while at the same time withstanding high mechanical forces. Our 3rd generation module is flow optimized to achieve the maximum performance of the ceramic membranes. The four large internal filtered water channels allow for flux rates up to 1,500 LMH (equal to 9 m³/hr) with one single module at minimal pressure losses. The entire housing, as well as all accessories are free of any metals and therefore usable in the harshest applications and at the same time achieving a very long lifespan. Additionally, no surrounding frames or hose connections between the modules are required.

Benefits: ▪ Less filter area needed due to high flux operation – high CAPEX savings ▪ Suitable for seawater and other challenging applications without any risks of corrosion problems ▪ Operation at hot temperature up to boiling water ▪ Fully modular due to no surrounding frame – option to change number of modules per tower at any time either to optimize project costs or to increase the plant capacity in future ▪ Most compact design – towers can be installed in close distance to each other as no hoses are needed 4.1 Module 6.0 S The Module 6.0 S is our standard for most applications. ▪ Filtration module with ceramic flat sheet membranes suitable for submerged applications ▪ Multi ceramic plate configuration with exchangeable single ceramic plates ▪ Internal filtered water piping ▪ Module housing fully made of glass fiber reinforced resin – free of any steel parts ▪ Suitable for harsh applications like groundwater, seawater, surface water, MBR, TSE and other challenging industrial waters ▪ High flux operation up to 1,500 LMH Specifications
