General-purpose treatment chemicals are often designed as one-product-fits-many solutions, but their performance can be limited in difficult water matrices. Products relying mainly on charge neutralization may not overcome steric stabilization in wastewater with high organic loading, while those relying on polymer bridging can be weakened by charge screening in high-salinity systems. Under high-salt, high-oil or high-solids conditions, this often results in excessive dosage, weak flocs, slow settling and increased secondary sludge.
Effective treatment therefore depends less on simply increasing dosage and more on matching the chemical program to the water chemistry and colloidal system. Coagulants destabilize colloids by compressing the electrical double layer and neutralizing surface charge. Flocculants then bring the destabilized particles together through adsorption, bridging, enmeshment and sweep flocculation, creating dense, settleable flocs. Working together, they complete the full sequence of destabilization, flocculation, settling and separation. A single chemical generally addresses only one stage, which is why tailored blends deliver greater value.
Based on this treatment approach, GN New Chem develops customized wastewater chemical programs, supported by integrated R&D, manufacturing, sales and technical services.
In-House Formulation Development
For each industry and treatment objective, we formulate tailored coagulation, flocculation and dewatering programs. Multiple mechanisms work together to improve adaptability and process stability under complex operating conditions.
One-Stop Product Portfolio
Our portfolio supports the critical stages of flocculation and settling, colloid destabilization, sludge dewatering, COD reduction and solid-liquid separation. Customers benefit from complete product coverage, reliable supply and a balanced focus on performance and total treatment cost.
On-Site Technical Support
We provide end-to-end technical support through a structured process: site sampling and analysis → laboratory screening → formulation optimization and field trials → on-site application guidance. Treatment results are monitored continuously to ensure stable implementation.
GN New Chem is an emerging technology-driven company focused on demanding, application-specific conditions.
