Re: Reply: Introducing x-runner mobile system

Hi Jessixr,

Just answering to the extract of your mail quoted below…

“SANITATION IN PERU
10 million people in Peru, one third of the population, do not have access to proper sanitation. Lima is the 2nd driest capital in the world. As the city is running out of water, it struggles to provide water and water-based sewer connections for all its inhabitants: in Lima, about 3 million people (600,000 families) lack access to sanitation facilities. Due to the city’s water shortage, the public sewage company Sedapal has began to reach out to new solutions in the alternative sanitation sector this year (among others; x-runner) with the aim to reach the 3 million people that they will never be able to provide with water-based sanitation.
x-runner works in Villa El Salvador, the oldest slum of Lima. Villa El Salvador, just as all the other shantytowns in Lima, has been built on top of sand dunes and instable grounds of Lima’s desert. For the past decades it has been growing without any great deal of urban planning on sanitation or water infrastructure. In Villa el Salvador and other shantytowns, family members of all ages usually live under one roof. They have basic education, they might own items such as televisions or a fridge, but they do not have a proper toilet. They use buckets or pit latrines – two methods that have been proven unhygienic and inconvenient: they cause foul odour, provide breeding grounds for insects and diseases and they contaminate the grounds and the ground waters of entire neighborhoods. Families struggle with chronic stomach diseases, and children with diarrhea.”


This sounds like common problems of many big cities grown in coastal areas and lacking fresh water and working sanitation systems. Why don’t you try to use saltwater from the nearby ocean to wash the sludge from collector points down to a treatment station, let it decompose (anaerobic and aerobic bacteria exist in saltwater as well), dry it (using heat generated –see your desert climate- from solar collectors) and then burn the remaining dry sludge using high temperature combustion to generate electrical power? The basic technology needed exists and doesn’t need new developments, the result would be cinder full of minerals that do no harm and conveniently scaled combustion power plants should be affordable (I know the main issue is collecting the feces from households and bring them to collecting points, but that’s the same issue with any other method, too). Particularly great cities as Lima do have a need for additional power sources, and combustion plants could be used, too, for burning environmentally-neutral plastic garbage etc.

Best regards,

Re: Introducing x-runner mobile system

Celia, gracias por la introducion. Por favs puedes explicar un poquito mas que es nuestro proceso de hacer compost? Como puedes ver, la traducion funciona mas o menos.

Dear Massimo, thank you for getting in touch! We would be very much interested to talk to Agua y Riles.
In the meantime we will read more on your website and write you again!

To Jürgen: thank you for your suggestions. Do you have any documents on the process that you propose? We are currently producing compost since gas and electricity is widely available in Lima, but soil is not. Lima is built on sand as it is in the middle of the desert - so there are almost no natural greenzones and there is a high demand for good soil here. Still, we are definitely looking in all possibilities and would be interested to further understand yours.

Re: Introducing x-runner mobile system (piloting in Lima, Peru)

Hi, Les comento un poco de lo que hacemos, aunque Jessica lo menciono anteriormente, aproximadamente recogemos de 43 familias las heces mezcladas con el material secante (aserrín) recolectados durante una semana, luego hacemos un proceso de compostaje, este inicia con el vaciado de los recipiente y le incorporamos hojas semi secas, para que no haya mucha proliferación de moscas. El tratamiento consiste en humedecer las pilas que requieren del agua, nosotros nos damos cuenta de ello mediante el método del puño, asimismo tomamos temperaturas diarias y en eso nos basamos para realizar el volteo (aireación). Actualmente se esta llevando a cabo un seguimiento del proceso del compostaje con respecto a la erradicación de los patógenos, llegamos a temperaturas elevadas 65 a 70ºc pero de todas maneras se necesita adicionar otro paso dentro de nuestro procedimiento para alcanzar temperaturas más altas que serán beneficiosas para la erradicación total de patógenos. Estamos considerando la importancia de obtener un producto Compost inocuo y que vaya con las exigencias de calidad, garantía y que contribuya en el desarrollo de una vida sostenible de las personas.

Hi , I commented a bit of what we do , but Jessica mentioned above, approximately 43 families collect feces mixed with drying material (sawdust) collected during a week, then make a composting process that begins with the emptying of incorporate the container and semi dry leaves , so that there is not a lot of fly breeding. Treatment consists of wet batteries require water , we realize it by fist method also take daily temperatures and that we rely for the turning ( aeration ). It is currently being followed up the composting process with regard to the eradication of pathogens , we arrived at elevated temperatures 65-70 º c but anyway you need to add another step in our procedure to higher temperatures that will be beneficial to total eradication of pathogens. We are considering the importance of obtaining a Compost product safe and go with the requirements of quality, reliability and contribute to the development of sustainable living people.

Re: Introducing x-runner mobile system (piloting in Lima, Peru)

Me olvidaba, los resultados físico químicos de nuestro compost, se encuentran en rangos que van dentro de los parámetros químicos, (Norma austriaca O-NORM S2023)

Re: Introducing x-runner mobile system (piloting in Lima, Peru)

A quick translation of Celia's reply:

Hi, I commented a bit of what we do and as Jessica mentioned above, from approximately 43 families we collect feces mixed with drying material (sawdust) once a week. Then we start a composting process that begins with the emptying of the full container and then mix it with semi dry leaves, so that there is not a lot of fly breeding. We treat our material in humid piles that we regularly irrigate, we know it is still a partly controlled method, but we do measure daily temperatures and that we rely for the turning (aeration). Currently our composting process is analyzed and evaluated regarding the eradication of pathogens (we arrived at elevated temperatures 65-70 º c) but we need further development in our procedure to achieve higher temperatures that will be beneficial to total eradication of pathogens. We highly emphasize the importance of obtaining a safe Compost product and we pay attention to be aligned with international requirements of quality, reliability in order zo contribute to the development of sustainable living situation for our customers.

Re: Introducing x-runner mobile system (piloting in Lima, Peru)

Primero que todo, felicidades por este proyecto tan lindo y ojalá todo les funcione bien. Mi pregunta es respecto a la adición de aserrín: ¿Aserrín de qué madera es? Leí que el aserrín en general no es muy recomendado, y el peor es el de pino por su acidez. Pueden verificar eso en algunas publicaciones que prueban tratamiento comparando aditivos. Lo principal es: ¿Están consiguiendo niveles de parásitos o microorganismos bajos, es decir, que cumplan alguna norma peruana o intercacional? ¿De veras les funcionó la infiltración de la orina? En varis unidades aquí en Chile, la infiltración tuvo complicaciones debido a la escasa permeabilidad de la tierra. Saludos!

First of all, congratulations on this project so cute and hopefully everything will work well. My question is regarding the addition of sawdust: wood sawdust what is? I read that sawdust is not generally recommended, and the worst is pine for its acidity. They can verify that in some publications that test comparing treatment additives. The main thing is: Are they getting parasites or micro levels low, ie satisfying any Peruvian or international standard? Really it worked infiltration of urine? In various units here in Chile, the infiltration had complications due to low soil permeability. Greetings!

Re: Introducing x-runner mobile system (piloting in Lima, Peru)

Buenos días, con respecto a tus preguntas, nosotros usamos aserrín de maderas duras, como es el caso de copaiba, capirona, Huayruro, Pumakiro y Cachimbo.

Con respecto a la infiltración de la orina, esta resultando muy bien, puesto que el lugar donde estamos trabajando tiene un suelo arenoso, aunque tenemos varias inquietudes con respecto a la infiltración en la nueva comunidad, puesto que su suelo es rocoso. Estamos investigando en ello.

Asimismo, estamos haciendo un seguimiento por fase al proceso de compostaje, son análisis microbiológicos para realmente saber si las temperaturas y el proceso está erradicando a los patógenos.

Saludos, Celia

Good morning, regarding your questions, we use hardwood sawdust, such as copaiba, capirona Huayruro, Pumakiro and Cachimbo.

With regard to the infiltration of urine, this being very good, because the place where we are working with has a sandy soil, although we have several concerns about the infiltration of the new community in which the soil is rocky. We are investigating it.

Also, we are following the process for composting phase are microbiological analysis to really know if the temperatures and the process is eradicating pathogens.

Re: Introducing x-runner mobile system (piloting in Lima, Peru)

Actualmente no tenemos ninguna norma peruana con respecto al compost, pero si queremos llegar a los estándares que presenta la OMS.

Re: Introducing x-runner mobile system (piloting in Lima, Peru)

Les puede servir de referencia la norma chilena 2880 del año 2004 del compost, tiene requisitos de maduración, metales pesados (en fecas son practicamente despreciables), niveles de E.coli, Salmonellas y ovas helminticas.

También les podría servir el reglamento de manejo de lodos en Chile: Decreto n°4 del año 2010. De ahí destaco las dosis recomendadas de lodos para aplicar por metro cuadrado, criterio de maduración de sólidos volátiles (que las fecas tienen bastante).

Definitivamente guiarse por los parámetro s de la OMS es lo más apropiado, pero estas normas pueden ser un referente técnico muy útil como fue para nosotros en BIS Chile. Saludos y mucho éxito!

They can serve as reference standard 2880 2004 Chilean compost has matured requirements, heavy metals (in feces are practically negligible) levels of E.coli, Salmonella and helminth eggs.

They also could serve sludge management regulations in Chile: Decree No. 4 of 2010. Hence feature recommended doses of sludge to be applied per square meter maturation criterion volatile solids (feces that have enough).

Definitely parameter s guided by the WHO is the most appropriate, but these rules can be a useful technical reference as it was for us in BIS Chile. Greetings and good luck!

Re: Introducing x-runner mobile system (piloting in Lima, Peru)

Hola Rodrigo ... cuéntanos un poco de tu proyecto BIS, de que trata, que es lo que utilizan como material secante, que tratamiento utilizan para las heces, como logran erradicar los patógenos, entre otros.

Re: Introducing x-runner mobile system (piloting in Lima, Peru)

De lo que haya disponible, BIS ha instalado baños en zonas rurales y algunos pocos en campamentos (no sé como le dicen en Perú, pero son terrenos a veces del estado, o a veces tomados donde la gente pobre construye sus casas y no hay urbanización, siendo la falta de saenamiento una constante).
De los aditivos preferidos se ha usado ceniza de hornos de barro en zonas rurales, compost, hojas, tierra seca y aserrín, siendo este último el más usado en campamentos. Hemos hecho algunas mediciones de patógenos directamente del tambor de tratamiento antes de la disposición final, con resultados satisfactorios. Acá el aserrín es principalmente de pino y eucalipto, siendo el aserrín el que menos funciona en la práctica. Como el público objetivo acá es altamente disperso, es inviable hacer una colecta centralizada como ustedes, que consiguen liberar al usuario de la responsabilidad sanitaria. Hasta la fecha se han construido 68 baños, pero ahora en BIS estamos en fase de desarrollo técnico del producto BIS, donde hemos hecho estudio exhaustivo de todo, desde genética parasitaria, epidemiología, ciencias del suelo y el agua, en donde la parte sanitaria y la interfaz producto-usuario son clave.
Esto desembocará finalmente en el diseño final y definitivo del baño, ya que hasta ahora se han probado diferentes diseños cada uno con sus ventajas y desventajas.
A mi juicio, el parámetro clave del tratamiento in-situ yo lo llamaría 'esponjosidad'. Por muy absurdo que suene, resume la humedad, la aireación y la razón C/N en un sólo parámetro fácil de controlar. Se logra con materia orgánica seca de baja densidad: fibra de coco, paja, pasto seco. La idea es dejar aire atrapado en la pila de fecas, bajarle la humedad, y aumentar el contenido de carbono, siendo todos parámetros clave para un compostaje apropiado. Poniendo esto en práctica, el material fecal recibido por ustedes en su centro de compostaje, estará mucho mejor condicionado para un proceso de compostaje de alta temperatura (aunque por lo que veo ya lo están logrando). Te invito a gustar nuestra página en facebook y te posteo un artículo que se hizo en el extranjero sobre BIS, tiene un poco de historia del origen y videos:

startupbuzz.la/en/the-reward-of-the-unsexy/

Como referencia, somos un equipo de ingenieros y algunos estudiantes de último año de ingeniería, principalmente de la Universidad Técnica Federico Santa María en Valparaíso. Yo ahora me encuentro en último semestre de ingeniería ambiental. Saludos!

From what is available , BIS has installed toilets in rural areas and a few camps (do not know as they say in Peru , but are sometimes the state land , or sometimes taken where poor people build their houses and no complex , saenamiento be the lack of a constant) .

Preferred additives ash has been used clay ovens in rural areas, compost , leaves, sawdust , dry land , the latter being the most used in camps. We made some measurements of pathogens directly from treatment drum before final disposal , with satisfactory results. Here sawdust is mainly pine and eucalyptus sawdust being the least work in practice .

As the target audience here is highly dispersed , it is not feasible to collect money centrally like you, who get free you of the responsibility care. To date we have built 68 toilets, but now we are BIS under BIS Product technical development , where we have made thorough study of everything from parasite genetics , epidemiology , soil science and water , where the health and user interface are key producers .

This will ultimately lead to the final and definitive design of the bathroom, and so far have tried different designs each with its advantages and disadvantages.

In my view, the key parameter in- situ treatment I would call ' fluffiness ' . As absurd as it sounds, summarizes moisture , aeration, and the ratio C / N in one easy to control parameter . Organic matter is achieved with low-density dry : coconut fiber, straw, dry grass . The idea is to let air trapped in the pile of feces , lower the humidity , and carbon content increases , with all key parameters for proper composting . Putting this into practice , fecal material received by you in your compost center will be much better conditioned to a process of high temperature composting (although I see they are already achieving ) . I invite you to like our facebook page and posting an article I was abroad on BIS , has a little history of the origin and videos:

startupbuzz.la/en/the-reward-of-the-unsexy/

For reference, we are a team of engineers and some senior students of engineering , mainly from the Technical University Federico Santa Maria in Valparaiso. I am now in final semester environmental engineering . Greetings !
