Every single day people go online, punch " landfill leachate" into an online search engine window. It is routine, and most searchers are looking for a solution to a leachate problem, which with the right knowledge beforehand, could have been avoided. So. let's examine the three main reasons, points, mistakes or actions which a person may like to avoid here. Only for background understanding, let me say that you'll need to know that free landfill leachate which appears at the base of a landfill must be managed carefully, or if it escapes into the environment around a landfill it will cause pollution. Leachate is produced by all Municipal Solid Waste (MSW) landfill sites other than those in desert regions. Even there, leachate may be produced in the very wettest years. Additionally, specifically, you should know that landfill leachate is one of the most highly organically contaminated liquids commonly encountered from any process, with the possible exception of leachate from active commercial compost heaps or "piles". Specifically what things should we avoid? And just why would anyone hope to prevent them? When you are working with landfill leachate, then you'll need to treat it with caution, and respect its high strength and ability to cause significant polluting effects (impacts) from only quite small quantities. Let's take a look then, at the 3 very most important points to avoid: First of all, fresh young acetogenic leachate is the most obnoxious and should be (if permitted and wherever possible) recirculated into the waste cells from which it trickles out, and the landfill operator must avoid it giving out unpleasant odors. This really is of major significance since this type of leachate contains many VFAs (Volatile Fatty Acids - fatty acids with a carbon chain of six carbons or fewer) and mercaptans which make it very smelly, which could cause many complaints, from people living locally, about landfill odors. It is hard to know when you have taken enough action to be enough to avoid landfill leachate problems as the weather/rainfall over the period will have a big an unpredictable effect. So, the landfill operator should plan ahead for suitable leachate extraction equipment to be available when needed. The second is, that the landfill operator must avoid leachate extraction equipment failures. As, odors will be accentuated if the ability to remove leachate from the base of the waste fails due to poor selection of landfill extraction pumping equipment. Always take expert advice from and experienced landfill extraction pump supplier. Suppliers new
to landfill leachate may ask what the pH of the liquid to be pumped is, however, corrosion is experienced to be more acute in most MSW landfill leachate due to the range of chemicals present, and pH alone will not guarantee a suitably corrosion protected leachate extraction pump is supplied. And lastly, never use aluminium components in a leachate extraction pump where the aluminium will be in contact with leachate. leachate corrodes aluminium rapidly and sooner than usually predicted by suppliers. And exactly how can we determine when this has been avoided adequately? The proof will be seen in the reliability of the landfill leachate management, and in the prevention of (for example) all odor nuisance to those living around the landfill. By avoiding these three things you are going to have avoided the majority of the problems. This should help you enormously to avoid what should really be avoided.
