Saving water and energy has never been more important for flower growers. Faced with rising costs and limited natural resources, efficient water management is essential for every production business, as well as for the environment and the community.
This study tour saw first-hand Sustainable Production Technologies for the Cut Flower Industry. Israel, Spain and the Netherlands were visited to assess specific areas of interest. – Design and application of new water efficient technologies (inground and hydroponic) – Identification and … Continued
As with all machinery, pumping systems will decline in efficiency over time, either due to abnormal operating conditions, or through normal wear and tear. To keep the system functioning at peak efficiency it’s important to monitor pumping performance on a regular basis, but it … Continued
Most flower growers are time poor but Andrew now appreciates the importance of making time to monitor the system regularly to ensure that benchmarks of pressure, flow rate and energy consumption are being met as a simple means to keep input costs down and maximise … Continued
Information about reducing the costs of water useage
The first step in the assessment process was to determine the efficiency of the pump. This was achieved by conducting a pump assessment where operating pressure, flow rates and electricity consumption were measured. During this assessment, recirculation cavitation noise was apparent, and from the … Continued
During the design and assessment of pumping systems, one of the factors that must be taken into account is the effect of cavitation on pump efficiency. Cavitation is a phenomenon where, under certain conditions, vacuum bubbles are created within the pump, leading to increased pump … Continued
The RADS program had a strong technology focus and information generated aimed to: • Identify and test component tools and technology that improve water management strategies. • Assess the effect of precision irrigation on crop response and system performance. • Introduce … Continued
Case Study Highlights: Irrigation Pump Annual Energy Cost Reduction: 83% Irrigation Pump Energy Efficiency Improvement: 47% Estimated Payback Period: 21 days
It seems that the higher irrigation frequency improved the biomass production but did not affect the quality of harvested flowers and consequently increased the greenhouse water use efficiency.
