Discussion Understanding Sanitary Landfill Sanitary Landfill

Discussion Understanding Sanitary Landfill Sanitary Landfill can be seen in the post below :
Sanitary Landfill Ad / : A way to the place where the garbage disposal is low and covered with soil to meet the requirements - sanitary requirements . Garbage is transported and disposed of to a place that is far away from settlements with backfilled soil layer after layer , after the first litter and the soil compacted .
Important aspects in the operation of the sanitary landfill
1 . The election of factors that should be considered :

    The land area required ( Age Sanitary Landfill , Total Trash ) .
    distance haulage
    The state of the ground
    climate
    Ground water
    geology and hydrology .
    Environmental conditions
    End use after completion of the Sanitary Landfill ( parking lot , Golf Course , warehouse etc. )
2 . The reaction that occurs in SL who have perfect
3 . Various methods of sanitary landfills
4 . Gas and leachate from landfills
Technical requirements of the sanitary landfill

    Compacting garbage every day ( Daily Cell of refuse )
    Landfill every day as thick as ± 15 CM after compacted ( Daily earth cover )
    After reaching a certain height , it is the final cover of soil about 70 cm when compressed ( top earth cover )
    Requires ventilation ( perforated pipe - hole ) for chemical processes , biological and physical decay during and stabilizing .
Equipment and facilities for Sanitary Landfill

    Tractor equipped Bucket and Shovel . 1 piece for a max of 50,000 inhabitants , and each additional 50,000 residents require the addition of a tractor .
    Place u / rest and where u / store equipment , as well as a complete office with wc and water supplies .
    fire brigade
    Water trucks and water pumps
    Traffic signs
    Insects and insecticide spraying equipment
    Fencing to prevent trash strewn .
    Equipment weighing vehicles and garbage .
Failure sanitary landfill
In general sanitary landfill is influenced by :
1 . season
2 . Frekueni garbage collection ( scavengers )
3 . Lack of tools and fire costs , accidents and t4 biological vector
Advantages & Disadvantages of Discussion Sanitary Landfill
1 . profit

    When the available land is very economical method ( sanitasix )
    Once completed it can be used as lpngn parking , airport etc.
    Lower initial capital investment compared with other methods
    The gas produced from the decomposition process if managed properly can be utilized as energy .
2 . loss

    Land that is not available in areas of high population density
    A decrease in the surface , so it requires regular maintenance
    Should be closed every day that require power .
    Combustible methane gas and other gaseous decomposition results may pose danger

Psychological Requirements healthy home

Psychological Requirements healthy home
Psychological requirements
Healthy home should have a good division of space , the arrangement of furniture is neat , not over cowding , and so on . Psychological requirements over cowding cause negative effects on physical health , mental , and moral . The spread of communicable diseases are rapidly occurring solid occupants . In addition , areas like this , the bustle and noise will increase , which will cause disturbance to tranquility , whether individuals , families , and entire communities around it . In addition , tranquility and confidentiality (privacy ) of each individual will be protected and will result in decreased morale accesses . Housing legislation in some developed countries authorize the government to menaggualangi problems like this . Home or residence revealed over cowding when the number of people who slept at home that shows the following .
1 ) Two individuals of different sexes , and the age of ten years and not bersetatus as husband and wife , slept in one room .
2 ) The number of persons in the household than the floor area exceeds the specified provisions . Healthy home is a house that is not over crowding the tranquility and comfort of a person could be disrupted if the residence or house belonged to the over- crowding

Biogas Formation Process

Biogas Formation Process
Biogas is produced from the decay process in the field of raw materials in the digester tank . Biogas is a byproduct HSIL than the decay of organic matter . Decay process can be aerobic or anaerobic . In the process of aerobic decomposition , aerobic bacteria use oxygen and produce ammonia , anaerobic bacteria remodel organic material into biogas , dirt , and organic fertilizer
liquid . The process of decomposition of organic matter is carried out by microorganisms in the fermentation process . Work processes rather than the bacteria can be divided into three stages , namely polymer breakdown stage ( Stage 1 ) , organic acids pembentuka phase ( Phase 2 ) and methane production phase ( Phase 3 ) .
Phase 1 ( Solving polymer )
At this stage a group of microorganisms to decompose organic substrates . This decomposition is done by various types of bacteria . The bacteria that play a role , among others, have cellulolytic enzymes , lipolytic and proteolytic . The resulting enzyme hydrolysis accelerates the polymer becomes soluble monomers which is a substrate for microorganisms second stage . Cellulolytic bacteria play a role in this stage . The optimum working temperature is 50-60 ° C ( bacteria thermophilik ) and temperature 30
- 40 ° C ( bacteria mesophilik ) . Both groups cellulolytic working in a pH range of six to seven . In this process the possibility of a decrease in pH can occur due to the formation of organic acids . This needs to be stabilized by the addition of lime solution . If the bacteria stage 2 and stage 3 have been working and equilibrium reactions in the pH range from seven systems . Working synergistically always occur among the various kinds of bacteria in the breakdown of the polymer becomes soluble monomers . One study showed that the rate of breakdown of the polymer was higher in medium containing a mixture of cellulolytic bacteria and nonselulolitik than in medium containing pure cultures of cellulolytic bacteria . The monomer formation stage is the stage of decomposition of the waste time in controlling this . It is caused by bacteria fermenter working very slow compared with the bacteria working stage 2 and stage 3 . The decomposition rate depends on temperature , type of substrate and pH of the system .
Phase 2 ( Formation of Organic Acids )
Bacteria at this stage produces organic acids are formed from soluble monomer compounds . The results of this greatest of bacteria asetogenik is acetic acid , propionic acid and laktet . Methanogenic bacteria largely utilized acetic acid . Several species of methanogenic bacteria can produce methane from hydrogen gas
and carbon dioxide , which is where this material be produced during the decomposition of carbohydrates . Besides methane can also be produced by reduction of methanol or other byproducts during the breakdown of carbohydrates . Microbiology in ditahap process is not yet clear . Some species of bacteria work in this stage , and the proportion of acid , hydrogen gas , carbon dioxide and alcohol produced depends on the existing fra and environmental conditions .
Phase 3 ( Methane Production )
Methanogenic bacteria are very sensitive to the environment . This is because the bacteria must be in a state of the anaerobic , then a small amount of oxygen can hinder pertumbuhanny . Not only that , these bacteria are also conserved to a compound that has a high oxidation state such as nitrite and nitrate . These bacteria are also sensitive to changes in pH . The optimal pH range for the production of methane is 7.0 to 7.2 , but the gas is still reproduced in the range of 6.6 to 7.6 . if the pH is below 6.6 will be a limiting factor for bacteria and pH below 6.2 will eliminate the ability of methanogenic bacteria . In such circumstances asetogenik bacteria remain active until pH 4,5 - 5.0, so that the necessary buffer to neutralize the pH . Some compounds are toxic to the bacteria . The compounds include ammonia ( over 1500 -3000 mg / l ) , total ammonia nitrogen at pH above 7.4 , ammonium ions ( more than 3000 mg / l of total ammonia nitrogen at pH sedmbarang ) , dissolved sulfide ( more than 50-100 mg / l ) and salt solution of some metals such as copper , zinc and nickel .
