The circulating water has a lot of sludge and high turbidity; I seek advice from experts
Thread Content
1. The circulating water system uses fresh water as make-up water. 2. Electrode descaling equipment and bypass filtration equipment are installed in the cooling tower tanks to maintain the mass concentration of calcium ions in the circulating water at 160–260 mg/L. 3. No corrosion and scale inhibitors nor non-oxidizing biocides were added, and regular wastewater discharge was not carried out. 4. On-site inspection revealed severe growth of fungi and algae on the walls of the cooling tower and the recirculation pool, as well as along the edges of these structures and on their columns. There were adhering substances on the packing material, and black, lump-shaped fungi and algae appeared on the surface of the side filtration collection tank. 5. When cleaning the tube bundle of the water cooler, severe scaling occurs inside the tube bundle due to the heat exchange medium, making cleaning difficult and reducing the heat exchange efficiency. 6. Oil bubbles are floating on the surface of the circulating water. 7. Turbidity: 99. 8. The current situation needs to be changed; I seek advice from those with more experience
We used to have problems with river water as well; it took three months to clean the heat exchangers through pickling, which disrupted production. Things improved a lot after switching to ultra-filtered water for the cooling towers
Our factory has two tanks; one of them is in good condition and basically doesn’t require water changes. One that gets covered in algae almost within a month and needs to be drained and cleaned. It is maintained by the same water treatment manufacturer; the temperature of the water in Zhangzao tends to be higher
Does \"using ultrafiltrated water in cooling towers\" mean that the water used in the circulation system is treated through an ultrafiltration unit?
We use water from the Yellow River; its quality is very poor, and it has never been cleaned or treated with a protective film. Discharge is basically not allowed. Does using ultrafiltrated water in your cooling towers increase costs?
Could you advise on how it is maintained on a regular basis?
Scale inhibitors and bactericides need to be added. For those that require continuous wastewater discharge, an additional bypass filtration system is also needed.
Our pool is small and uses tap water. It is the manufacturers outside who come regularly to add chemicals. Even so, the manufacturer comes to drain and clean that pool once a month
Strict environmental regulations apply; discharge is not allowed, and there is a side filtration system
We are a large petrochemical company; draining and cleaning can only be done during shutdowns
In that case, it is necessary to seek qualified and capable manufacturers in the circulating water maintenance industry to carry out the assessment and maintenance work
