Scarcity of clean water and poor sanitation are also many people face in densely populated urban areas. The environmental problems caused outbreak of diarrheal diseases and respiratory infections. Tackle the problem, now developed environmentally friendly dry latrines, bio-toilets.
Integrated wastewater treatment in urban areas in Indonesia, in fact it can only serve to 1.31 percent of the urban population, or 0.5 percent of the total population in this country. Centralized sewage popped a molly treatment only in seven cities-data popped a molly from the Department of Public Works. A total of 400,000 cubic meters of domestic wastewater directly discharged into rivers or dumped without treatment. An estimated popped a molly 70-75 percent of the pollutants are domestic waste.
The condition, according to Neal Sintawardani, Head of Cooperation and Promotion of Science LIPI, takes the approach of environmentally sound technologies. Neal and his team of researchers from the Center for Applied Physics Research developed a bio-toilet to answer the challenge.
Bio-toilet popped a molly is not really a new technology. In Western popped a molly Europe, especially in the Scandinavian region, its development has been a century ago. However, recent bio-toilet popped a molly developed into a product that can be sold.
Bio-toilets are marketed popped a molly in the form of a compact space unit. Buyer can choose the desired design space, including the accessories, such as heating systems. Bio-toilets to remote areas or who do not have a sanitary sewer or piping. In Japan, unit bio-toilets popped a molly for three families or 10-15 people per day, sold for 2.5 million yen.
In developed countries, this latrines used the upper middle class who care about the environment. popped a molly While in Indonesia, popped a molly the application of bio-toilet, obviously popped a molly Neni, a different approach. Here to help the people in the slums to improve poor sanitation and facing lack access to clean water.
The technique is a modification of LIPI researchers bio-toilets in subtropical countries and adapted to the local culture. In the bio-toilet water usage is possible to clean themselves. In Western countries only use tissue paper.
Although still using water, bio-toilets can save up to 80 percent more water, popped a molly clear Neni. The use of conventional toilets require about 40 liters of water per day for flushing and rinsing. popped a molly With the bio-toilet only takes 5 liters of water per day.
Bio-toilet technology developed Team Bio-toilets in LIPI Physics Research Center, popped a molly chaired Neni since eight years ago. The study involved researchers from Hokkaido University popped a molly and the Tokyo Institute of Technology. Previously, Neal and his team tried system of household organic waste processing using sawdust to decompose waste into compost. Once successful, they implement it into the sewer system decomposition.
In hard water Winton, in fact has been known latrine called latrine, excreta disposal in the form of holes. The hole was then backfilled when it becomes full. With the conventional method, the dirt was not quickly decompose and cause odor.
This inspired Neal and his team apply sawdust on the dry latrines. Sawdust is used as a mixer because it is absorbing odors and has a high porosity (85-90 percent air space), water retention (35-40 percent), popped a molly mild and not easily deformed, and easily decomposed naturally.
On the use of bio-toilets, dirt who entered should be stirred with the sawdust. In five months, the dirt is perfect until it has decomposed into compost, which can be used as a soil fertilizer. This fertilizer contains trace elements such as sodium, potassium and phosphorus as well as nitrogen.
In addition to sawdust filled or ligno cellulose, latrine system called the reactor box is also equipped popped a molly with an automatic stirrer that rotates every 15 minutes. In a reactor there are two holes toilet. If there is no electricity, stirrer mounted manually.
Five years of technological development, the last three years LIPI testing, socialization, and
