Products for oily emulsions, hydrocarbons, refractory organics, nitrogen, foam and membrane reuse.
Petrochemical wastewater may contain free and emulsified oil, hydrocarbons, aromatic compounds, ammonia, salts and process chemicals. Effective source control and oil separation are required before biological and membrane treatment.
GZXZEP supplies emulsion breakers, specialized microbial cultures, external carbon sources, defoamers, industrial odor products and RO chemicals for selected applications.
| Treatment challenge | Treatment approach | Relevant GZXZEP products | Application point |
| Stable oily emulsions | Screen OWT grades by jar testing before flotation or settling. | OWT Series Emulsion Breaker | Physicochemical pretreatment |
| Hydrocarbon or aromatic COD | Improve oil removal and evaluate specialized cultures. | XZ8851; XZ8831; XZ8811 | Biological treatment |
| Ammonia and nitrate instability | Review nitrification, denitrification and carbon separately. | XZ8821; XZ8822; NBC-70W/NBC-44WS | Aerobic and anoxic stages |
| Wastewater foam | Select by foam test and compatibility review. | XZ8605 | Foaming zone |
| Industrial exhaust odor | Use as polishing in compatible wet scrubbers. | NPD3010 | Scrubber recirculation water |
| RO reuse | Select membrane chemicals from feedwater and foulant data. | XZ9901/XZ9902/XZ9903/XZ9905/XZ9906 | RO feed and CIP |
The OWT Series supports emulsion breaking before flotation or settling. XZ8851 targets hydrocarbon-affected systems, XZ8831 targets aromatic compounds and XZ8811 supports broader COD degradation after upstream oil control.

XZ8821 supports aerobic nitrification, XZ8822 supports anoxic denitrification and NBC-70W or NBC-44WS supplies external carbon where required. XZ8605 may control wastewater foam after compatibility testing.

NPD3010 may polish industrial odor in a compatible wet scrubber but does not replace primary hazardous-air-pollutant control. RO chemicals must follow membrane limits and feedwater analysis.

GZXZEP provides product selection, laboratory evaluation and application support. Final performance depends on wastewater characteristics, process conditions, equipment and site operation.
XZ8851 is the listed hydrocarbon-degrading microbial consortium. Free oil should be removed before the biological trial.
XZ8831 is intended for wastewater containing persistent aromatic organic compounds.
No. It is an odor-polishing product for compatible wet-contact systems and does not replace required VOC or hazardous-air-pollutant controls.
Provide the wastewater source, flow, recent analysis, current treatment process, chemicals now in use and the required discharge or reuse target. A sample may be requested after the initial review.
Share the oil profile, organic compounds, nitrogen data, treatment process and reuse target for product screening.
