Three simple ways to optimize water consumption

Is it possible to optimize water consumption in industry and agricultural production with simple adjustments? 

Europeans are estimated to use billions of cubic meters of water every year not only for civilian consumption, but also for agriculture, industrial production, heating and cooling, tourism and other service sectors. Agriculture is the sector that exerts the highest pressure on renewable freshwater resources in general, accounting for 59% of total water consumption in Europe.

In Europe, approximately 284 000 million m3 of water are withdrawn each year to meet the needs of the European economy. In 2017, a volume of about 266 billion m 3 of water was withdrawn, of which about 40% was consumed by the economy and 60% was returned to the environment with a certain level of physical or chemical alteration.

In 2017, the manufacturing sector in Europe was responsible for 10.6% of water consumption in the entire economic sector.

Given these figures, it is natural for us to ask what we can do as manufacturers of nozzles, washing heads and atomizers.

3 simple ways to reduce water consumption in industry and agricultural production

1 | USE THE RIGHT TYPE OF NOZZLE FOR A SPECIFIC APPLICATION

Choosing the correct nozzle for an application is very important.
It will allow you to achieve excellent results and to optimize resources, be they water, economic or energy.

A spray nozzle is a device which makes use of the pressure energy of a liquid to increase its speed through an orifice and break it into drops.
Its performances can be identified and described precisely, so that the design engineer can specify exactly the spray nozzle required for a given process.

Several technical characteristics must be taken into consideration to select the correct nozzle for a given application.

2 | IDENTIFY IRREGULARITIES IN THE SPRAY PATTERN AND REPLACE THE NOZZLE IF WORN

A nozzle can gradually deteriorate due to abrasion and, as this occurs over time, the orifice or the internal passage widens. This leads to a greater flow and to a greater consumption of water, causing losses in economic terms for the company but also in environmental terms for the planet. A symptom of deterioration of a nozzle is certainly an irregularity in the spray pattern.

We list below what are the characteristics of regular spray patterns:

3 | USING FILTERS

In a process plant a plugged nozzle can cause all types of issues, from troublesome maintenance problems to severe breakdowns. It can cause damage to the spray and therefore also an increase in the use of water. The protection of your spraying system by means of an adequately selected filter or filtering system should always be considered while designing your production process.

To figure out mesh sizes one has to count the number of openings from the centre of any one wire to the centre of a parallel wire one inch away.
The number of openings in a filter cartridge is the mesh size. We highly recommend to add filters to small capacity nozzles to hold fine particulate matter.

Mesh | number Free passage | mm
30 – 320.6 – 0.58
500.30
600.25
750.20
800.18
1000.15
1500.10
2000.075

The largest filter free passage must be smaller than the nozzle orifice
If the nozzle tip diameter is 0.3 mm, we suggest you to choose a 60 mesh filter or more (free passage 0.25 mm). Please consider that the higher is the number of
mesh, the greater is the filtering power.
