简体中文
1. Low-phosphorus biodegradable eco-friendly formula; wastewater can reach national secondary discharge standard (total phosphorus ≤1.0 mg/L) without additional phosphorus removal treatment.
2. Dual-function integrated formula, simultaneously inhibiting mineral scaling and forming compact anti-corrosion film on carbon steel pipelines and heat exchangers.
3. Maintains stable performance under harsh working conditions: high water hardness, high alkalinity, high concentration multiple and long hydraulic retention time.
4. Contains polymer dispersants to disperse iron oxide, silt and suspended solids, reducing heat transfer efficiency loss caused by surface deposits.
5. Low-foam liquid design prevents cooling tower foam overflow and will not block water circulation pipelines.
6. Wide compatibility with conventional oxidizing and non-oxidizing biocides; low effective dosage reduces long-term chemical consumption cost.
FAQ
Question | Answer |
What industrial systems is SGR0804 suitable for? | It applies to open circulating cooling water systems of chemical plants, power plants and petrochemical factories with strict phosphorus emission limits. |
What is its core environmental advantage? | Ultra-low phosphorus content greatly lowers total phosphorus discharge, helping factories meet increasingly strict environmental protection regulations. |
What is the standard dosage range? | Normal dosage: 20–60 ppm; adjust according to raw water hardness, alkalinity and system concentration multiple. |
Can it work for high concentration multiple operation? | Yes, it stably controls scaling and corrosion under high concentration cycles to reduce water blowdown volume. |
Can it be mixed with biocides directly? | Compatible with most common biocides; a small compatibility test is recommended before large-scale mixing. |
How to store the product properly? | Keep original barrels tightly sealed, store in cool, ventilated warehouses, avoid direct sunlight and freezing environments. |

Performance Characteristics:
(1)It is a green water treatment formulation, featuring both biodegradability and low phosphorus content. The discharge water can meet the National Secondary Standard for Environmental Sewage Discharge (Total Phosphorus ≤1.0 mg/L) without requiring special treatment.
(2) Compared to other all-organic alkaline treatment formulas, it is more suitable for operating conditions with high hardness, high cycles of concentration, as well as high temperature and long residence times. This agent uses the latest efficient dispersants and corrosion inhibitors to effectively control metal (carbon steel, copper alloy, stainless steel, etc.) corrosion and heat exchanger scaling.
(3) Utilizes our company's modified PESA high-performance scale inhibitor and dispersant product, providing excellent prevention against scaling and suspended solids deposition. This technology is one of the latest in water treatment. Using this product can prevent scaling in recirculating water systems that traditional programs cannot handle. It also offers very good dispersing performance under conditions of high water temperature and low flow velocity, reducing the formation of iron, phosphate, and foulant deposits.
(4) Employs an AA/AMPS/HPS dispersant product, which effectively prevents scaling and suspended solids deposition. When combined with appropriate microbial control, it effectively prevents foulant deposition, thereby avoiding under-deposit corrosion which is prone to occur when chloride and sulfate concentrations are high in recirculating water.
Application:
As a scale and corrosion inhibitor, it exhibits excellent ability to inhibit carbonate scale in water with high Ca²⁺and high alkalinity, and has good dispersing properties. It is suitable for recirculating cooling water systems with high cycles of concentration and high pH values.
Usage Method:
Dosage varies depending on the water quality indicators and process parameters of the application system. Generally, based on the makeup water volume, the dosage concentration should be controlled between 20~50 mg/L. Suitable for pH range 7.0 – 9.5.
Packaging, Storage & Transportation:
Packed in 25 kg, 200 kg, or 1000 kg plastic drums. Store in a cool, dry place. Shelf life is twelve months. Handle with care during transportation to prevent impact.
