| CPTDC provides flocculants, scale inhibitors, corrosion inhibitors and bactericides, etc, to clarify wastewater, inhibit corrosion and scale and kill bacteria. These chemicals can protect formation from plugging and reduce down time. 
Flocculant (XN)
XN is a yellow inorganic macromolecular compound. Both solid and liquid products are available. Its water solution shows faintly acidity. XN can be fed easily without using other additives. The water treated by XN is clear and its pH remains unchanged throughout the treatment. It can be applicable to a wide range of water temperature from 0 ℃ to 100 ℃ and the speed of floc forming is high (30-60 seconds).
● Specification| Test parameters | Properties | | Oil removal efficiency | ≥90% | | Membrane filtration coefficient | ≥20 | | Suspended solids removal efficiency | ≥ 85% |
● Application
XN is applied in treating waste water in rivers, oilfields, oil processing plants and paper mills.
● Package
Packed in plastic pails (25 kg for each)
● Safety
Avoid contact with the eyes, skin and clothes. HFI Series Flocculant
HFI flocculants are mainly made from alumina powder, belonging to inorganic macromolecule water purification agents. They have powerful bridging, absorption capabilities, along with characteristics of swift reaction speed, large floccule, fast moulding, and high fitration efficiency. ● Specification| Test parameters | Properties | | HFI (liquid) | HFI (solid) | | Apparence | Amber or brown Liquid | Amber or brown power | | Specific density (20 ℃) | 1.10-1.30 | － | | Alumina content | ≥9% | ≥27% | | Water insoluble content | ≤1 | ≤3 | | pH (1% aq. solution) | 3.0-5.0 | 3.0-5.0 | | Basicity | 45%-85% | 45%-85% |
● Application
HFI flocculants can be used in the treatment of industrial wastewater, oilfield wasterwater and injected water, etc. They are effective to remove suspended solids, COD, BOD, chromaticity, oil dissolved in water, etc. The dosage is usually 50-100 mg/L, and should be decided on the results of the laboratory and field tests.
● Package
HFL (liquid) flocculant should be packed in plastic pails (25 kg for each). HFL (solid) flocculant should be packed in multiwall sacks (25 kg or 50 kg for each), with PE film lining inside.
● Safety
Store in a dry place. HSI Series Scale Inhibitor
HSI series scale inhibitors are formulated mainly with organic polybasic phosphoric acid, and supplemented with other types of auxiliary agents. They are mainly used to inhibit carbonate scale and are perfectly stable at high pH value, and can form stable complex compound with metals such as iron, copper, zinc, aluminium, etc.
● Specification| Test parameters | Properties | | HSI (ordinary) | HSI (concentrated) | | Apparence | Colorless or amber liquid | Colorless or amber liquid | | Specific gravity (20 ℃) | 1.200-1.350 | 1.300-1.500 | | Solubility (1% aq. solution) | Homogeneous liquid | Homogeneous liquid | | Effectiveness content | ≥35.0 | ≥50.0 | | pH (1% solution) | 1.0-4.5 | 6.5-8.0 | | Freezing point, ℃ | ≤-5 | ≤-10 | | Anti-scale efficiency (10mg/L) | ≥75.0% | ≥90.0% |
● Application
HSI scale inhibitors are suitable for anti-scale of circulation cooling water, industrial water, oilfield wastewater and injected water. They can also be used for anti-scale of gathering pipes of high water content cruck oil. The dosage is 5-10 mg/L. HIS (ordinary) scale inhibitor is required to be injected at upstream before the pressure and temperature are changed. HIS scale inhibitor (comcentrated) is required to be injected in either one of two liquids before they are mixed.
● Package
Packed in plastic pails (25 kg for each) or metallic drums (200 L for each) or ISO drums (1000 L for each)
● Safety
Low toxicity; store in a dry and ventilated place Deflocculant & Sequestrant (HS-323)
HS-323 is a Na salt made from polycarboxylate, low molecular weight polyacrylic acids and their corresponding sodium salts. It contains no phosphorous and can inhibit the deposition of calcium carbonate, calcium sulfate, barium sulfate and other low solubility salts .It has good activity over a wide pH range, water hardness, temperature conditions and has excellent stability in the presence of hypochlorite.
● Specification | Test parameters | Properties | | Appearance | Colorless to pale yellow clear solution | | Active Content | 39.0%-41.0% | | pH (1% solution, 25 ℃) | 2.1-2.5 | | Specific gravity (20 ℃) | 1.16-1.26 |
