Abstract
An as fact, 2% of the Palestinian population in the West Bank live in Jordan Valley. This valley has high agricultural value since it produces 50% of the total agricultural production In Palestine. However, this area suffers from a lack of water because of the current political situation. Therefore, the water distribution is being done on a periodic basis and farmers need to store water on site so as to be able to irrigate their field during the anonymous days. This nature of the water pumping process and the limited amounts of available water for irrigation pushed farmers toward constructing artificial ponds in their farms so as to be used at the time where there is no water available from the main source. However, artificial ponds may affect the environment negatively due to the creatures which live in it such as Algae that attracts mosquitos and causes bad smell. Thus, in this paper, a simple and low-cost photovoltaic based pumping system is proposed to inject chemical material in the water of these artificial ponds to get rid of algae. The proposed system is mainly consisted of a pump that is powered by a photovoltaic array and pumps the proposed chemical material which is potash alum in the artificial pond using a rotary nozzle that is fixed on a pipe around the ponds. The system is affordable and reduces the production of the unwanted creatures. As a result, the system reduces chemical Oxygen demand (COD) value from 7200 mg/L to around 95 mg/L, which is considered the main cause of algae blooming. The product is powered by 50W foldable solar panel and it costs about 213 USD.
