Automated Polymer Unit POLYPACK® Preparation Systems Automated system for the liquid or powder polymer preparation, designed for homogeneity in flocculant concentration Optimized design to ensure the polymer goes through the maturation process using the smallest footprint The POLYPACK®, Polymer Dosing System is a compact unit that automatically feeds the process, as needed, using a regulated ultrasonic level switch. Baffles allow the circulation of the polymer preparation through a series of compartments. This ensures the optimum reaction time in each compartment and, a continuous concentration level, thereby avoiding any preferential route between the preparation compartment and the final dosing solution compartment. The POLYPACK® system is automated by the control panel connected to the ultrasonic level detector located above the dosing solution compartment. As soon as the solution in the dosing compartment reaches “low level”, the detector activates the opening of the water feed electrovalve and the start-up of the dry feeder. The water meter controls the flow continuously. As soon as the “high level” is reached, the process cycle stops, although the mixers (one, two or three according the model) continue to operate. The POLYPACK® unit provides automatic and continuous preparation of the polymer solution using a constant and uniform quality, resulting from: - One two-impeller mixer located in the preparation compartment (single impeller in the maturation compartment), - Optimized maturation cycles. By fitting with an optional dilution unit, the main solution can then be diluted. Benefits: - Avoid the need for manual operations – Prevent dosing errors, operation stops. - Standardization of the obtained polymer – Concentration, maturation time, homogeneity. - High efficiency mixers – Provide a low flow mixing for a homogeneous flocculant polymerisation without mechanical deterioration. - Optimised process – Visual access to the process and alarms, fieldbus distributed control (optional) provides informative and easy to access equipment and status application updates, controlled costs. Intelligent system that feeds the process when needed, regulated by an ultrasonic level switch. - Reliability and Robustness in Any Environment. - Option DUAL – Two-in-one solution, to prepare powder or liquid polymers. Ideal solution for wastewater plants located in areas subject to population changes, such as tourist areas, or locations subject to rainy season that have to adapt their process according to the population equivalent or the season. - Compact design – For easy transport and relocation. Specifications: - Tanks available in HDPE, 316L S.S. and 304L S.S. Two or three-compartment tanks according to model. - APX for powder or powder/emulsion: 12 volumes in standard : from 132 to 3,170 gallons (500 to 12,000 litres). - ALX for emulsion: 7 volumes in standard, from 132 to 1,057 gallons (500 to 4,000 litres). - Extraction/dosing flow from 105 to 6,340 GPH (400 to 24 000 l/h) - Concentration for make-up solution preparation up to 0.5% (5 g/l) - Control panel: PLC controller programmed by Milton Roy for automatic operation.

Deflagration Flame Arrester, short time burning-proof, End-of-Line weather hood with protection screen protects the PROTEGO® flame arrester unit against environmental impact, such as nesting animals and weather conditions available for DN 50/2“- bis DN 800/32“- pipes trouble-free maintenance advanced design for higher operating temperatures provides protection against atmospheric deflagrations and short-time burning low operating and lifecycle costs cost-effective flame arrester cost-effective spare parts Function and Description The PROTEGO® LH/AD-T end-of-line deflagration flame arrester provides protection against flame transmission through atmospheric deflagration and short time burning on the flame arrester element. The device is typically installed on vent lines of vessels and plant equipment which are not pressurized. The device is equipped with a temperature sensor which immediately detects a flame on the FLAMEFILTER® surface. After the flame is detected, a secondary measure, such as inerting or closing of a shut-off valve to block the vapor flow to the device, should activate within 60 seconds and extinguish the flame so that the system can operate safely. The device prevents flame transmission from short time burning and atmospheric deflagration into the vessel or plant. The PROTEGO® LH/AD-T consists of the housing (1), a weather hood (2), and the PROTEGO® flame arrester unit (3). The device is equipped with a metal weather hood. The FLAMEFILTER® (4) gap size depends on the device’s intended use. Specifying the operating conditions, such as the temperature, explosion group, and the composition of the fluid, enables PROTEGO® to select the best end-of-line deflagration flame arrester for your application. The PROTEGO® LH/AD-T series end-of-line deflagration flame arrester is available for substances from explosion groups IIA to IIC (NEC groups D to B). The standard design can be used with an operating temperature of up to +60°C / 140°F. Devices with special approval for higher temperatures are available upon request. Type-approved in accordance with the current ATEX Directive and EN ISO 16852, as well as other international standards.

Pressure Relief Valve deflagration- and endurance burning-proof 10% technology for minimum pressure increase up to full lift due to 10% technology, set pressure is close to opening pressure for optimum pressure maintenance in the system as compared to conventional 40% or 100% technology set pressure close to opening pressure for optimum pressure maintenance in the system valve opens later and closes earlier than conventional valves valve pallet is guided inside the housing to protect against harsh weather conditions can be used as a protective system in areas with potentially explosive atmospheres in accordance with ATEX PROTEGO® flame arrester unit provides protection against atmospheric deflagrations and endurance burning integrated PROTEGO® flame arrester unit saves space and weight and reduces costs PROTEGO® flame arrester unit is protected from clogging and sticky substances caused by product vapors minimum pressure loss of the PROTEGO® flame arrester unit flameproof condensate drain maintenance-friendly design modular design enables replacement of individual FLAMEFILTER® discs and valve pallet Function and Description The deflagration-proof and endurance burning-proof D-SVL-EB type PROTEGO® valve is a highly developed pressure relief valve for large flows with an integrated flame arrester PROTEGO® EB. It is primarily used as a device for flame transmission-proof out-breathing on tanks, containers, and process equipment. The valve offers reliable protection against excess pressure and prevents product losses almost up to the set pressure; while at the same time protecting against atmospheric deflagration and endurance burning if stabilized burning occurs. The PROTEGO® flame arrester unit is designed to achieve minimum pressure drop with maximum safety. PROTEGO® D-SVL-EB valves are available for substances for substances of explosion group IIA (NEC group D MESG > 0.9 mm). When the set pressure is reached, the valve starts to open and reaches full lift within 10% overpressure. This unique 10% technology enables a set pressure that is only 10% below the maximum allowable working pressure (MAWP) of the tank. After years of development, this typical opening characteristic of a safety relief valve is now also available for the low pressure range. The tank pressure is maintained up to the set pressure with a tightness that is above the conventional standards due to our state-of-the-art manufacturing technology. This feature is ensured by the valve seats made of high quality stainless steel and with individually lapped valve pallets (1), or with an air cushion seal (2), in conjunction with a high quality FEP diaphragm. The valve pallets are also available with a PTFE seal to prevent the valve pallets from sticking when sticky substances are used and to enable the use in corrosive fluids. After the overpressure is released, the valve re-seats and provides a tight seal. If the set pressure is exceeded, explosive gas/product vapor/air mixtures are released into the atmosphere. If this mixture ignites, the integrated flame arrester PROTEGO® EB (3) prevents flame transmission into the tank. If additional mixture continues to flow and stabilized burning occurs, the integrated flame arrester unit prevents flashback as a result of endurance burning. The valve is protected and also fulfils its function under these severe conditions. The spring-loaded weather hood opens as soon as the melting element (4) melts. The valve can be used up to an operating temperature of up to +60°C / 140°F and meets the requirements of European tank design standard EN 14015 – Appendix L and ISO 28300 (API 2000). Type-approved in accordance with the current ATEX Directive and EN ISO 16852 as well as other international standards.
