How can you remove platnium from a car converter?
there is no practical way to "do it yourself" they are recycled in a lengthy chemical dilution and reclimation prosses
How is city water treated?
Domestic sewage from washrooms and toilets is taken to sewage treatment facilities which can range in size and complexity from septic tanks to tertiary treatment systems.The simplest of municipal treatment systems is simply a series of sewage lagoons which hold the total volume of sewage allowing lumps tp settle and the organics to be removed by natural oxidation and bacterial processes. After holding for about a year the sewage is released, generally at the time of high spring flows, to a local watercourse. There are often two lagoons in a system one fills while the other sits idle and dry. The full lagoon is taken off line when full, the second lagoon fills while the first ages. The full lagoon is emptied. When empty, the flow is once more diverted to it while the (now full lagoon ages until it discharged, restarting the cycle.The steps in the processes at larger treatment plants are:Primary Treatment (De Lumping)The incoming sewage is comminuted (blended) to reduce large lumps.The fine particles are put in a separator where floating material is skimmed off for alternate disposal, settleable material is removed for alternate disposal. The water in the middle is either discharged or sent to Secondary TreatmentSecondary Treatment (Removing fine particulates and dissolved organics)The fluid from the Primary system is put into an aerated basin where the sewage is mixed with air. Microbes in the sewage eat the dissolved organics.The mixture of uneaten particles and microbes is transferred to a seperator where the microbes settle and are collected. They are divided. Part of them are sent back to eat more sewage, part are sent to disposal This sludge is transferred to a separation tank whereA portion of the sludge's are removed for disposal in anaerobic digesters.Anaerobic digesters which convert the microbe bodies and particulate to methane gas to power the treatment processes.The solid free liquid from the separator is discharge to the environment or sent to Tertiary treatment.An option at this stage is to adjust the bacteria colony for nitrogen removal.Tertiary Treatment (A final polishing)To remove traces of organics, odours, viruses and very fine particulates some sewage treatment plants provide another stage of treatment. This can include chlorination, filtration or even reverse osmosis.
What flora and fauna are native to England?
Trees: Oak, Elm, Ash, and Beech are the most common trees of England Flowers: Some wild flowers you can find in England are wild rose, honeysuckle, and sea lavender Plants: Varied vegetation of grasses and flowering plants. Wild vegetation consists of the natural flora of woods, fens, marshes, cliffs, chalk downs, and mountain slopes. The widespread being heather, grasses, gorse, and bracken of moorlands. Mammals: Wolf, Bear, Reindeer are extinct(englands larger mammals) but red and roedeer are protected for sport. Common smaller animals are, foxes, hares hedgehogs, rabbits, weasels, stoats, shrews, rats, mice, otters(found in many rivers) and seals(seen frequently along the coast). There are few reptiles and amphibians. Birds: Roughly 230 species of birds reside in England and another 200 are migratory. The most bemourous are chaffin, blackbird, sparrow, and starling. The number of large birds is declining except for pheasant, partridge, and red grouse which are protected for sport. With reclimation of marshlands Waterfowl are moving into bird sanctuaries. Insects: 21,847 bugs inhabit England the most common is the Caddisfly. Fish: The rivers and lakes abound in salmon, trout, perch, pike, roach, dace, and grayling.
