How to reduce the impact of water jet cutting system on the environment

There is no solution. Operating the water jet cutting system requires a lot of water. If you use an abrasive water jet system, you are mixing water and abrasive - a process that produces wastewater by-products. Dealing with these by-products has aroused the environmental concern of many users of water jet systems, but what measures can you take? As it turns out, there are many things you can do to alleviate these concerns.
You can add many different methods and equipment to the water spray system, which will greatly reduce its impact on the environment. Some of these include:
cooling-water machine
Closed loop filtering system

Abrasive removal system

Let's explore some of the available system add ons and how they can reduce the impact on the system.
cooling-water machine
The ONEJET waterjet chiller can be used in two ways as a way to reduce the water consumption of the sprinkler system.
The closed loop cooler can be used with your pump, eliminating the need for any cooling water in the pump's hydraulic circuit. For example, this can save a water spray system equipped with a 50 horsepower pump, which uses about 4 gallons of water per minute for the cooling circuit. Then, the only waste water comes from the water used in the actual cutting process.

The online cooler is used in combination with the closed loop water filtration system to remove waste heat from the water in the whole system circulation. This includes cutting water and cooling water. After the water in the loop passes through the filter system, the compressor cools the water in the cooler. The filtered cold water is then returned to the loop for reuse. The in-line chiller greatly extends the maintenance interval of the pump and keeps it at the highest level during the long cutting process.

A simple way to greatly reduce the impact of the water jet cutting system is to configure it as a closed loop. The closed loop system prevents wastewater from draining directly into the drainage system - this is particularly problematic when using an abrasive system that mixes garnet with water to produce wastewater. In addition, the closed loop system enables the water to be recycled in the loop, thus greatly reducing the water consumption in the cutting process.

In the closed loop system, the workbench of the water jet cutter overflows into the weir groove, where the abrasive precipitates. Then, the water is filtered out through a series of filters, and then the purified water is sent to the cooler, and then sent back through the circuit. If your plant layout does not have a drain to discharge wastewater, you must use a closed loop system. By keeping the circulating water clean and meeting OEM specifications, these systems improve pump performance and reduce wear on machine parts. This will have a significant impact on the maintenance intervals of the entire system.

If you are using an abrasive water jet cutting system and want to reduce the impact of using abrasive on the environment during the cutting process, the abrasive removal system is an ideal accessory. An abrasive removal system designed to remove abrasive from the tank eliminates the need to manually remove waste garnet from the tank. Hoppers in these systems receive wastewater (also called sludge) so that the purified water can be returned to the header tank.

The cleaner assembly at the bottom of the tank is an indispensable nozzle, which can keep the abrasive suspended in water, so that the antiwear agent system can pump the sled to the tank for separation. This greatly reduces the downtime of the cutting system and increases the maintenance interval of the collecting tank.
