New Rendac wastewater treatment plant produces energy
Technology news Filtration+Separation July/August 2012
High flow filter removes New Rendac wastewater treatment oil in corrosive plant produces energy environments and its metallic parts meet NACE Standard MR-01-75, resisting sulphide stress cracking and discolouration in well-head and other corrosive environments. The half-inch ported F22H is designed with a large convoluted filter element, creating a large surface area to deliver high flow with minimal pressure drop. The filter is equipped with a stainless steel manual drain. It is also available with an automatic drain that opens when a specified liquid level is attained, making it especially well suited for unmanned satellite platforms. Users report production gains due to better filtration and reduced contamination.
The new stainless steel coalescing filter from Norgren for use in corrosive environments.
Norgren has introduced a new stainless steel coalescing filter for use in corrosive environments, such as offshore oilrigs, refineries and chemical plants. The high flow filter has been developed to protect sensitive equipment and remove oil from compressed hydrocarbon gas or compressed air used to power operations in these applications. The F22H from Norgren is constructed of 316 stainless steel
The maintenance cycle of the F22H coalescing filter is extended when used as part of Norgren’s three-stage filtration system. Two general purpose filters placed upstream remove water and particles of 25 microns and then 5 microns before they can contaminate the coalescing oil removal element. The three-stage system comes with brackets for panel mounting to fit into a compact footprint. Both the stand-alone filter and the three-stage system are available with a stainless steel and nylon service life indicator that shows when the filter element is contaminated. www.norgren.com
Rendac Son, part of VION Ingredients, and the Dutch water technology company Paques have agreed on the construction of a new wastewater treatment plant that will produce green energy. Rendac Son collects and processes all animal residual material (such as animal carcasses and slaughterhouse waste) of the Netherlands. In the factory in Son (in the southern part of the Netherlands), the major part of the animal waste is converted into biofuel, mainly used by power plants. This process produces a large amount of wastewater which now is treated in a conventional wastewater treatment plant. This takes a relatively large amount of energy. In the new plant, anaerobic treatment (which converts organic wastes into biogas) will be combined with the ANAMMOX® process (in which nitrogen is efficiently removed). In a combined heat and power plant (CHP), the produced biogas will be converted into both electricity and heat. The amount of electricity produced and the savings compared to the current WWTP is an equivalent of the energy consumption of approximately 3,000 households. “Within VION Ingredients, innovation and sustainability of existing processes are important issues, and therefore anaerobic treatment is not unknown to
us. However, the nitrogen in the wastewater was a bottleneck for successful application of this treatment in the Rendac process. It is very difficult to remove nitrogen with traditional processes. The ANAMMOX® process has proven itself over the last decade. In cooperation with Paques, the feasibility of the combination of these techniques in our specific case was shown.” said Roel van den Borne, project leader on behalf of VION Ingredients. “In our industry we are the first company to realise such a combination of technologies. The new installation will also be used for the wastewater of the existing energy park Ecoson and is suitable for processing the wastewater from the future bio-phosphate project. This project contributes to the further optimisation and sustainability of the energy consumption of Rendac as well as of the adjacent Ecoson. Also, the new facility enables a yearly reduction of 1,600 ton in CO2 emissions.” The future wastewater treatment plant has, according to the common standards for this type of effluent, a very small footprint. The biogas produced is biologically desulphurised with the THIOPAQ® process. www.paques.nl www.vionfoodgroup.com
