Wastewater — Process Challenge

Coagulantes y floculantes para remoción de turbidez

El agua cruda o de proceso y la alimentación del clarificador arrastran turbidez coloidal que no sedimenta. El diseño desestabiliza los coloides con coagulantes de sal metálica o poliamina (neutralización de carga) y luego los une en flóculos sedimentables con polímero de alto peso molecular

RawSource supplies the base chemicals that go into these programs. We can help with product selection, grade matching, and sourcing from multiple origins for supply security.

Typical Treatment Workflow
1
Water & System Assessment
Characterize the water and the system — hardness, alkalinity, pH, TDS/conductivity, microbial load, and the metallurgy and temperatures of the equipment being protected.
2
Program & Chemistry Selection
Match coagulants, flocculants, scale and corrosion inhibitors, biocides, or pH adjusters to the water profile and discharge limits, factoring compatibility with any existing program.
3
Jar Testing & Dosing
Confirm coagulant and flocculant dose and feed point by jar test, set inhibitor and biocide treat rates, and size packaging (drums, totes, bulk) to consumption.
4
Monitoring & Control
Track residuals, turbidity, ORP, corrosion coupons, and effluent compliance, adjusting chemistry and dose as feedwater and load change.
Recommended Chemistries (6)
Aluminium Sulfate
CAS 10043-01-3
Ácidos y Sales
Coagulante estándar de alumbre
3264 (ALUMINUM SULFATE, SOLUTION) · Class
Alum hydrolyzes to Al(OH)3, neutralizing the negative charge on colloids and sweep-flocculating turbidity; the classic primary coagulant. (Role is coagulation, not pH adjustment.)
Punto de fusión:-16 °C   Punto de ebullición:101 °C at 760 mmHg   Densidad:2.71 at 20 °C 1.7 at 20 °C

Ferric Chloride
CAS 7705-08-0
Ácidos y Sales
High-performance coagulant
1773 (FERRIC CHLORIDE) · Class
Fe(III) hydrolyzes to dense Fe(OH)3 flocs effective over a wide pH and for phosphate/colour removal; stronger sweep coagulation than alum. (Role is coagulation.)
Punto de fusión:306 °C   Punto de ebullición:315 °C at 760 mmHg (Decomposes)   Densidad:2.8 at 20 °C (anhydrous solid)

Poly Aluminum Chloride (PAC)
CAS 1327-41-9
Aditivos Especiales
Quelación / Secuestro
Pre-hydrolyzed aluminum coagulant that works across a broad pH with less alkalinity consumption and lower sludge than alum. (Role is coagulation.)

Polyferric Sulphate (PFS)
CAS 10028-22-5
Ácidos y Sales
Iron-based coagulant
Pre-hydrolyzed iron coagulant giving fast, dense flocs and good colour/turbidity removal. (Spine mis-tags this Moisture Control; chemistry is iron coagulation.)
Punto de fusión:The Anhydrous form decomposes (480ºC)   Punto de ebullición:The Anhydrous form decomposes (480ºC)   Densidad:3.1 at 20 °C

PolyDADMAC
CAS 26062-79-3
Aditivos Especiales
Polímero coagulante catiónico
Cationic organic coagulant that neutralizes colloid charge without adding metal sludge; often used to cut metal-salt dose. (Role is coagulation.)
