Abstract:

This paper investigates the capacity of Nutrient Film Technique (NFT) to control effluent's heavy metals discharge. A commercial hydroponic system was adapted to irrigate lettuces with primary treated wastewater for studying the potential heavy metals removal. A second commercial hydroponic system was used to irrigate the same type of lettuces with nutrient solution and this system was used as a control. Results showed that lettuces grew well when irrigated with primary treated effluent in the commercial hydroponic system. The NFT-plant system heavy metals removal efficiency varied amongst the

Abstract:

The development of aquaculture with a hydroponic system is now more and more chosen by the community because of the increasingly limited land, but also comparable to the increasing demand for water. Hydroponics with the Nutrient Film Technique (NFT) system can be used as a solution to the water needs needed in the cultivation of hydroponics plants. This study aims to design the hydroponic installation of the NFT system and grow plants in the NFT system. The study was conducted with the stages of making the hut, making the installation, seeding, making nutritional solutions and transferring see

Abstract:

Hydroponics is a cultivation technique without soil. There are several modalities for the system and among them is the Nutrient Film Technique (NFT), which consists of using channels to circulate a nutrient solution intermittently. Due to the existence of risks of soil and water contamination in metropolitan areas, hydroponics is a potential alternative to conventional production. Therefore, the present work sought to verify the current study of knowledge of the NFT hydroponic system in the international literature and the performance of the countries on it. For this, a bibliographic survey wa

Abstract:

Nutrient film technique (NFT) is a hydroponic technique, whereby a very shallow stream of water containing all the dissolved nutrients required for plant growth is re-circulated past the bare roots of plants in a watertight gully, also known as channels. Problems commonly associated with NFT hydroponic system such as water temperature, can easily increase under direct sunlight in the tropics region, especially in the roof top garden, that can affect the quality of fertiliser used to cultivate the crop. Therefore, a study to develop a cooling system for NFT hydroponic technique is significant t

Abstract:

The human population significantly increases in crowded urban areas. It causes a reduction of available farming land. Therefore, a landless planting method is needed to supply the food for society. Hydroponics is one of the solutions for gardening methods without using soil. It uses nutrient-enriched mineral water as a nutrition solution for plant growth. Traditionally, hydroponic farming is conducted manually by monitoring the nutrition such as acidity or basicity (pH), the value of Total Dissolved Solids (TDS), Electrical Conductivity (EC), and nutrient temperature. In this research, the res
