Reed Elsevier Environmental Challenge Winners Announced
, One of the poorest regions in the country. In partnership with the Program for Appropriate Technology in Health, the school-based pilot involves a prototype chlorine generator using salt, water, and battery power to generate chlorine for water disinfection. On a single battery charge, the device can run for 200 cycles, generating 40,000 litres of clean water.The Reed Elsevier Environmental Challenge was open between July and .
Projects were evaluated on the degree to which they were replicable, scalable, sustainable, and innovative; emphasised solutions with practical applicability; addressed non-discrimination/equality of access from a scientific, legal or other basis; and involved a range of stakeholders and local communities.
According to the World Health Organisation, lack of water to meet daily needs is a reality for one in three people around the world. Poor access to safe water contributes to health crises in many developing countries, and increasingly leads to violent conflict. The Reed Elsevier Environmental Challenge contributes to the Water for Life Decade, established by the UN General Assembly, running between 2005 and 2015, in support of the Millennium Development Goal to reduce by half the number of people without access to safe drinking water and to stop unsustainable exploitation of water resources.
Dr. , Director of Corporate Responsibility at Reed Elsevier said, "The two winning projects fulfill the aim of the Reed Elsevier Environmental Challenge to provide clean and sustainable water to communities in need and, because they are scalable, the benefits can be widely dispersed. The Reed Elsevier Environmental Challenge is a tangible example of how we aim to use our networks and expertise to facilitate the exchange and dissemination of information to benefit society."
The two winning projects will be featured in the Reed Elsevier journal Water Research, and will be celebrated at a reception on 24 August in use water contaminated with arsenic at concentrations typically over 20 times the safe limit prescribed by the World Health Organization. The project involves an arsenic groundwater removal system using locally available chemical compounds and reusable sand filters. Ground water is pumped into an overhead tank, chemically stabilised, filtered using reusable arsenic-selective adsorbents, and converted into stable sludge/solids for safe long-term storage. Twelve community-level arsenic removal units are to be installed in remote villages and schools in .
Salt Chlorine Generator - News
In partnership with the Program for Appropriate Technology in Health, the school-based pilot involves a prototype chlorine generator using salt, water, and battery power to generate chlorine for water disinfection. On a single battery charge,
Pippin says the two most important high-tech elements are an in-floor filtration system and a salt-based chlorine generator. In-floor filtration, which traps multiple layers of debris, does not involve any sort of robot arm or snake-like object on the
chlorine generator (ECG) to help extend cell life. Pristiva Activator, added at start-up and throughout the season, is used to establish and maintain salinity levels. It replaces commodity pool salt and avoids problems caused by salt impurities.
Autopilot DIG220 Fried Board • Salt Water Chlorine Generators (SWG ...
This is a great site and this thread is PERFECT for the problem I have. I have those 4 capacitors domed and one blew out pretty badly and got so hot that it desoldered itself, so I am not sure of the polarity if I decide to replace all 4 caps. I need to call autopilot tomorrow morning to see how I am going to proceed, this is the beginning of our 3rd season with this unit, and I am hoping its under warranty. From my reading, I understand I can: 1) send this unit back to autopilot for them to repair the board, 2) replace the caps myself, 3) buy a new board or 4) go to another chlorine generator. The SWG should be grounded to the electrical system and bonded to the pool bonding system. The ground wire will be green and run along with the power supply wires. The bonding wire will be solid #8 bare copper and be connected to the pump as well as the pool frame or rebar in the pool shell. The SWG has separate connection points where each of these are supposed to connect. I just ordered a new Pool Pilot V4.4 for $581 delivered. After its warranty is over I plan to replace those 4 capacitors with better units from Digikey. I also plan to keep an eye on the caps for doming. Do you guys see any issues with me swapping out those 4 caps as a preventative measure with longer life higher voltage units of the same value?
