DecodingComo——A case study of a plastic products company in Ningbo

A certain plastic products company in Ningbo is a leading enterprise primarily engaged in the production of plastic products such as electric meter boxes and enclosures。

The company has over 100 injection moulding production lines. The cooling water is cooled by cooling towers and then pumped to each production line and systems like air compressors for cooling. Before the summer of 2015, an average of 5-6 injection moulds would fail daily due to scale buildup. When product issues arose, production had to be halted to clean the moulds, which not only delayed production schedules but also resulted in a high scrap rate. To mitigate the impact of scale, the company resorted to shutting。

In 2015, the business Installed the Como electronic water treatment system， The schematic diagram of the cooling system is as follows：

More than two years have passed. How is the production line of this company doing? We revisited the company in December 2017 and brought back water samples for testing。

The water quality data report is as follows：

Calculating the values of the circulating water detection, its Langlier saturation index shows a clear corrosion trend, but the iron ion content in the test results is very low, indicating that corrosion is well suppressed。

The CL- concentration in the water around the Jiangsu and Zhejiang regions is generally around 30, which suggests that the concentration factor of the cooling circulating water is over 10 times. The concentration factors of total hardness and alkalinity in this water body are within 4 times, because the Como electronic water conditioner promotes the formation of calcium carbonate, reducing the concentration factors of total hardness and alkalinity. Additionally, the concentration factors of conductivity and TDS in this water body are around 4 times, because the Como electronic water processor acts as a flocculant for the water body。

The customer introduced: For the past two years, the company's circulating water has not had any chemicals added, and there have been no more instances of the injection moulding production line being forced to shut down for cleaning。 This year, we only performed a maintenance inspection in October, during which we completely drained the cooling water tank. We found the tank to be very clean. Daily wastewater discharge is done through side filtration, with a small amount of water discharged during back washing every few days. The customer has been very satisfied with the operating condition over the past two years and has recognized the effectiveness of the Como water treatment system!

This is the capability of the Como water processor.：Concentration ratio More than 10 times, it inhibits corrosion， physically flocculates， and prevents scaling。 It not only ensures the production of enterprises but also meets current high environmental protection requirements, creating substantial wealth for enterprises and gaining customer recognition, which is not surprising. The Como water processor has a lifespan of over 10 years。

The Como electronic water treatment system is a single device that can be used in various systems, combining multiple functions such as algae elimination and sterilization, anti-scaling and descaling, and physical flocculation. It saves 5-30% energy and 75% water。

No need to contact water, no reliance on water flow, no restrictions from piping, no change in chemical composition, no need for shutdowns or production halts, no daily maintenance required, no interference with other electronic devices, consumes very little electricity, anti-scaling and descaling, physical flocculation, algae elimination and sterilization。
