WEBVTT 00:00:00.000 --> 00:00:04.000 Nice and good day, so at the beginning you can introduce yourself. 00:00:04.000 --> 00:00:12.000 My name is Frank Philippzig and I have been working in the waste water industry for many decades. 00:00:12.000 --> 00:00:20.000 In different positions and the last two decades as a manager employee in the municipal area. 00:00:20.000 --> 00:00:32.000 And I was the only employee there and was in charge of the problem of waste water from the sewer to the sewer. 00:00:32.000 --> 00:00:39.000 Where, why and how do you set up the waste water and what are the problems? 00:00:40.000 --> 00:00:51.000 The problem arises from the grease-resistant waste water, which we find very, very often in the municipal area. 00:00:51.000 --> 00:01:00.000 And starting at the pumping station to the pressure pipe, channel network and to the sewer. 00:01:00.000 --> 00:01:08.000 And the focus is here on the grease-resistant waste water in the pump supplies. 00:01:09.000 --> 00:01:22.000 And there, the basin is also used very often to carefully process these grease-resistant waste water or sponge layers. 00:01:22.000 --> 00:01:30.000 Thank you. Which problems are connected to the waste water treatment? 00:01:30.000 --> 00:01:37.000 The problems are very multi-layered, which arise from the grease-resistant waste water. 00:01:37.000 --> 00:01:48.000 At this point, I would also like to focus on the formation of a sewer, especially on the pressure pipe, but also on the supply containers. 00:01:48.000 --> 00:01:57.000 And which then lead to certain flow problems and thus represent the first problem. 00:01:57.000 --> 00:02:03.000 But overall, of course, there are many more problems that arise from the grease-resistant waste water. 00:02:04.000 --> 00:02:17.000 I would also like to focus on the formation of H2S, where we then have problems in the further waste water treatment, a bit for work protection and environmental damage. 00:02:17.000 --> 00:02:24.000 Which problems occur most often through grease-resistant waste water systems? 00:02:25.000 --> 00:02:42.000 The most common problems with H2S are to see that we have an oxygen form here, which leads to corrosion in buildings, in metal-holding armatures. 00:02:42.000 --> 00:02:52.000 And up to the problems in work protection, because H2S is a toxic gas. 00:02:53.000 --> 00:03:01.000 And the formation of H2S must therefore also be stopped or prevented. 00:03:01.000 --> 00:03:09.000 What causes H2S in waste water exactly and what countermeasures can you name? 00:03:10.000 --> 00:03:25.000 So H2S creates a sulfuric acid or sulfuric acid and thus corrosion occurs on the concrete, on the metal parts, on the points. 00:03:25.000 --> 00:03:37.000 This is one criterion that must be prevented, because the life time of the technical systems is reduced, thus causing costs. 00:03:38.000 --> 00:03:44.000 But as I said at the beginning, the working and living conditions are directly affected. 00:03:44.000 --> 00:03:56.000 And the employees here must be prevented from getting in touch with H2S. 00:03:57.000 --> 00:04:15.000 The waste water treatment itself is of course also a priority, where H2S, if H2S is not eliminated in waste water, it is even more difficult to eliminate the ingredients, the parameters, all in the follow-up process, in the clear systems. 00:04:15.000 --> 00:04:22.000 How do I turn Lipasan F on and how does it work? 00:04:23.000 --> 00:04:34.000 Lipasan F is quite simple to use, the manufacturer gives very clear instructions on how Lipasan is used. 00:04:35.000 --> 00:04:54.000 The amounts are different depending on the size of the relevant parts and amounts that are processed there, i.e. amounts of waste water and amounts of fat. Thus, the concentration of Lipasan is measured accordingly. 00:04:55.000 --> 00:05:07.000 The technical effort is very small and also the work time and handling of the employees is really manageable. 00:05:07.000 --> 00:05:20.000 It is a very simple process and you only need a little technical equipment to carry out the process and the effectiveness of Lipasan F successfully. 00:05:21.000 --> 00:05:25.000 What consequences does the use of Lipasan F have? 00:05:25.000 --> 00:05:33.000 The use of Lipasan F has very positive consequences for further waste water treatment. 00:05:34.000 --> 00:05:55.000 Here are the different steps that are called by Lipasan F during the fat division, namely two parts, the fatty acids and the glycerin, which is a valuable and important nutrient supplier as a result of the waste water treatment. 00:05:56.000 --> 00:06:20.000 This leads to further optimized waste water treatment in the entire process and ultimately serves as a carbon source for an ideal nutrient distribution in the biological waste water process and ultimately improves waste water cleaning. 00:06:21.000 --> 00:06:26.000 How and why does H2S occur in waste water systems? 00:06:27.000 --> 00:06:45.000 H2S occurs when fats are present in waste water and the waste process by microorganisms that are contained in waste water, the fats are removed in different parts. 00:06:46.000 --> 00:07:02.000 But conditions for this are anaerobic conditions and therefore the basic requirement is that H2S can occur in the waste process via different parts of this H2S, i.e. waste water. 00:07:02.000 --> 00:07:11.000 This H2S formation is a big obstacle in the further processing, as I mentioned at the beginning. 00:07:12.000 --> 00:07:25.000 And Lipasan is an innovative product that successfully results in the formation of H2S or the dissolution of the fatty products. 00:07:25.000 --> 00:07:30.000 What is the main cause of H2S formation? 00:07:31.000 --> 00:07:48.000 The main cause for H2S formation are the anaerobic conditions in the pump system below the sponge layer, because there can be no more oxygen exchange. 00:07:49.000 --> 00:08:04.000 A special environment has formed in this anaerobic condition and the dissolution of microorganisms occurs via different parts of H2S. 00:08:04.000 --> 00:08:16.000 And this can be prevented by dissolving the sponge layer with Lipasan and producing an air exchange again. 00:08:17.000 --> 00:08:22.000 What are the consequences of H2S in waste water and in waste water systems? 00:08:23.000 --> 00:08:47.000 The consequences are very multi-layered and wide-reaching. H2S leads to the formation of an acid and this acid leads to corrosion in various structures, i.e. concrete structures, metal-holding structures, pressure pipe lines, armatures. 00:08:48.000 --> 00:09:08.000 And the problem continues until the clear layer and due to corrosion in the different parts of the system and materials, the life time of these parts is reduced and the costs are increased considerably. 00:09:08.000 --> 00:09:11.000 Thank you very much for answering our questions. 00:09:11.000 --> 00:09:13.000 My pleasure.
