Dosing plant engineered for coagulants, flocculants, pH adjusters, disinfectants and speciality chemicals together — with the right materials, segregation and control for every reagent on one coordinated system.
Real treatment trains rarely dose a single chemical. A clarification plant may need coagulant, then polymer, then pH trim and a disinfectant — each with different chemistry, materials compatibility and control needs. A multi-chemical dosing system brings them together safely: correct wetted materials per reagent, strict segregation of incompatible chemicals, and one control philosophy that sequences and trims them in step.
Engineered for Every Reagent
Each reagent imposes its own demands. Ferric is corrosive; hypochlorite gasses and degrades; lime is abrasive and scaling; polymer is shear-sensitive and viscous. We select wetted materials, pump types and storage for each, keep incompatible chemicals physically and procedurally apart, and coordinate the lot from a single panel so coagulant-then-polymer trains and staged neutralisation run as one process.
Materials, pump type and storage selected individually for each chemical’s chemistry.
Incompatible reagents (e.g. acid and hypochlorite) kept apart by layout and interlock.
One reagent at several points, or several reagents in sequence, coordinated from one panel.
Sequencing and cross-loop trim so the whole train holds its targets together.
What Has to Be Got Right
Putting several reagents on one plant multiplies the compatibility, safety and control questions. These are the ones that matter most.
Acid and hypochlorite release chlorine gas if mixed — segregation and bunding are non-negotiable.
Each wetted part must suit its reagent; the wrong elastomer or plastic fails fast.
Coagulant pH shift changes polymer demand — loops must be coordinated, not independent.
How a Multi-Chemical System Is Built
Every chemical, its strength, duty and injection point is scheduled before design.
Incompatible reagents are separated by bund, layout and interlock.
Wetted materials chosen per reagent for pumps, pipework and seals.
Each reagent injected and mixed at the right point with the right energy.
Residual and quality feedback confirm the combined train hits its targets.
Typical pairings on a multi-chemical plant
| Reagent | Behaviour | Wetted material | Pump type |
|---|---|---|---|
| Ferric chloride | Corrosive | PVC / PVDF / PE | Diaphragm |
| Sodium hypochlorite | Gassing, degrades | PVC / PVDF | Peristaltic / diaphragm + degas |
| Lime slurry | Abrasive, scaling | EPDM / hardened | Peristaltic / PC |
| Caustic / acid | Corrosive | PP / PVDF | Diaphragm |
| Polymer solution | Viscous, shear-sensitive | PE / SS | Progressive cavity |
