Towards the use of activated charcoal filters in waster treatment plants, with the charcoal being produced from waste produced in the treatment plant.

家庭能源回收装置（HERU）显示出很大的希望，特别是在全球贫困地区。世界上16%的人口没有电，许多人在撒哈拉以南非洲和亚洲的偏远农村地区（能源获取数据库，2017年）。这些社区往往难以到达，因此很难为他们建立电网；由于电力线中的电阻，能量会损失，因此电力线可能不是理想的解决方案。世界上38%的人口使用生物质燃料做饭，通常是在明火/炉灶中效率低下，主要是在撒哈拉以南非洲和亚洲（生物质数据库，2017年）。HERU利用这些废物生产生物炭，其中含有较小比例的沼气和生物油，可以用作发电的燃料。这意味着电力是在使用点产生的。收集废物供HERU使用也可提高卫生水平。许多没有电力供应的地区无法获得清洁的饮用水。全球有7.83亿人无法获得清洁和安全的水，撒哈拉以南非洲地区有3.19亿人无法获得经改善的可靠饮用水源（The water Project, 2016）。这就是这项研究的目的，这项研究的目的是评估和开发HERU的使用，以解决清洁水危机，特别是在偏远的农村地区。实现这一目标的方法将是通过使用HERU生产不同的炭。可能在不同温度下产生生物炭；已经发现，与在较低温度下产生的木炭相比，在气化炉中在较高温度下产生的木炭作为过滤器使用更有效（水溶液，2010年）。这项研究的目的是进一步评估HERU中使用的不同类型的废物除了在不同温度下产生木炭外，如何影响生物炭从水中去除杂质的能力。不同类型的废物评估将包括：植物物质，如未使用的蔬菜可能是动物粪便。塑料。皮革。纺织品。合成。自然。动物粪便。

The Home Energy Recovery Unit (HERU) shows a lot of promise, especially in impoverished parts of the globe. 16% of the world's population are without electricity, many in remote rural areas of sub-Saharan Africa, and Asia (Energy Access Database, 2017). These communities are often hard to reach so building power networks to them is difficult; energy is lost due to resistance in power lines so power lines may not be an ideal solution. 38% of the world's population use biomass fuel for cooking, often inefficiently in open fires/stoves, again mainly in sub-Saharan Africa and Asia (Biomass database, 2017). The HERU uses this waste to produce biochar, with smaller fractions of biogas and bio-oil which can be used as fuel for producing electricity. This means electricity is produced at the use point. Collecting the waste for use in the HERU may also increases sanitation levels.Many areas with no access to electricity do not have access to clean drinking water. 783 million people do not have access to clean and safe water worldwide, with 319 million people in Sub-Saharan Africa without access to improved reliable drinking water sources (The Water Project, 2016). This is where this research will come in, the aim of this research is to assess and develop a use of the HERU to solve the clean water crisis, particularly in remote, rural areas. The way this will be achieved will be through using HERU to produce different chars. Potentially producing biochar at different temperatures; It has been found that char produced at greater temperatures in a gasifier is more effective in use as a filter when compared to char produced at lower temperatures (Aqueous Solutions, 2010). This research will aim to go further and assess how different types of waste used in the HERU effect the capability of the biochar to remove impurities from water in addition to producing char at different temperatures. Different types of waste assessed will include: Meats. Plant matter such as unused vegetables. Potentially animal waste. Plastics. Leather. Textiles. Synthetic. Natural. Animal Manure.
