Some possible reasons are – low liquid level, deposition of iron chips, etc. The above could lead to poor fluidity and cause an increase in contact area of cutting fluid and air which results in foaming.
Add cutting fluid on frequent basis. Please note the angle of the nozzle when applying it and avoid direct flushing at the right angles. This can reduce the chance of foaming.
The primary cause of odor is the large amount of bacteria in cutting fluid. We would suggest using clean water to blend with lubricants. This will prevent the bacteria from breeding and will increase the lubricity.
The bacteria will be inhibited when the PH value is in between 8.5 and 9.5. Thus, it is recommended to add new lubricants to maintain the right PH value. Apart from this, to extending the life of cutting fluid, we would suggest the use of centrifugal water-oil separator or chip removal machine to remove tramp oil and sludge.
Our specialists would be pleased to visit the site and evaluate for remedy if needed. If the issues remained unsolved, the cutting fluid in the sink will need to be replaced.
It is recommended to wear gloves and working suit during the operation process to avoid direct contact with cutting fluid. In addition, keep an eye on the PH value and add new lubricants as needed to prevent bacteria from breeding.
Such waste water contains numerous chemical substances and many potential contaminants which may harm the public health and safety, thus, the sewage is usually sent to waste-water treatment plant for treatment and purification.
To achieve green industry, we have introduced a concentrator specializing in wastewater treatment. It separates the cutting wastewater into water and concentration, which greatly reduces the treatment cost of wastewater.
