Well-head arsenic removal unit
Find out about our case studies:
On a clear, sunny day a small-sized PVP system with an installed solar module of 12 Wp (LJ1012) will pump approximately 300 liters water per day to a height of 6 meters. It would supply drinking/cooking water for up to 30 people. Young and healthy villagers could, depending on water quality, drink this water, but also elderly people and children could obtain their drinking water from this source after it has been filtered through an additional process.
Small and decentralized usable pumps are ideal for developing countries with electricity problems. The cost of drilling a deep borehole demands a huge investment; a mistake means a significant loss of time and money. With LIUJIA Solar pumps LJ3012, LJ2012, LJ1012 one is able to drill many simple and especially de-central located boreholes next to rivers or lakes, where underground water lies fairly close to the surface. If many small wells are built, it doesn’t influence groundwater resources negatively. Additionally the pump is perfectly suitable to deliver rainwater from underground containers in dry periods. Decentralization is advantageous for families in remote areas: a little well in the backyard supplies a few families with enough water and saves them the long way to the public pump station. Therefore costly distribution of water, water loss during transportation and energy used during transportation can be saved. The created efficiency and energy can be usefully spent on improving living conditions in the area.
If people don’t need to move into cities or villages for better living conditions, ground and other natural resources can be shared more equally in the future. This solution is not only cost effective, but it is also realizable by people without any technical knowledge.
