1. Company Profile

Henan Secco Environmental Protection Technology Co., Ltd. is a professional manufacturer and supplier of water treatment chemicals, specializing in polyacrylamide (cationic, anionic, non-ionic), polyaluminum chloride (PAC), and polyferric sulfate (PFS). To address the challenges of ceramic wastewater treatment, we offer proven chemical selection and process solutions to help customers achieve discharge compliance and water reuse.

2. Characteristics of Ceramic Wastewater

Ceramic production generat large volumes of wastewater from raw material grinding, glaze preparation, polishing and cleaning operations. Key characteristics include:

• Extremely high suspended solids (SS), typically thousands to tens of thousands mg/L, mainly clay, quartz, feldspar, and other inorganic particles.

• Particularum superficies negativa charged, causing mutual repulsion and very slow natural settling.

• Neutral to slightly alkaline pH(7.5–8.5) et temperatura ambiente.

• Contents, cum COD generis minimis; The treatment focus is solid-liquid separation.

3. Recommendationes de seleccione PAM

Pro superiora caracteribuspolyacrylamide anionis (APAM) pro sedimentatio coagulation is recommenditurquia:

• PAM animantica portat grupos negativo cargae qui particulas colloidales positivi cargae neutralizant (in praeceptu particulas potent cargas positivas portare a causa adsorbata calices) et per calicem molecularum longum possidet actionem bridgae fortem ad particulas inorganicas rapide aggregare in flos magnas densas.

• Parametri recommendati:

  • Molecular weight≥ 16 million (higher MW for larger flocs)

  • Hydrolysis degree20%–30%

  • Preparation concentration0.1%–0.3% (in aqua pura tinta dissolveta)

Fordewatering pulcherrima,polyacrylamide cationic (CPAM)is recommended at a preparation concentration of 0.15%–0.25% for efficient filter press operation.

4. Procedus recommendatus: PAC + PAM Enhanced Coagulation

While PAM alone is effective, combined dosing with inorganic coagulantpolyaluminium chloridum (PAC)Perfectionem significantem meliora facit et totam costum chemicalum minimat. The synergistic mechanism:

1. PAC velociter negativas charges in particibus neutralizet, duplicum layer electricam compress, et microfloque format.

2. PAM tunc haec microflocs in maiores, celeriores aggregatos pont.

Parametri procedentis (Valores referentiae)

In praecepto, adjust dosages according to actual influent quality; - It is strongly recommended to conduct jar tests to determine the optimal ratio.

5. Operational Guidelines and Precautions

1. Dissolution: PAM pulvere in aqua pura in temperatura inter 5°C et 60°C dissolvere debet. Praecipe pulverem similiter super superficiem aquae turbatum ut non efficiat formationem lumbos.

2. Conductionem miscans: Stirring speed during dissolution should be maintained at 100–300 rpm; excessive cauda catenas polymeros dissolvere potest et efficabilitatem reducere potest.

3. Sequentia Dosing:Add PAC first, then PAM. Rapid mix PAC for 1–3 min, then slow mix PAM for 5–15 min.

4. Storage: PAM solution should be used promptly; In loco frigido, sicco pulvere deposita est.

5. Nullus treatment: Sludge from the sedimentation tank should be conditioned with cationic PAM before dewatering in a filter press, achieving libi moisture content below 70%.

6. Expected Treatment Performance

Under optimized conditions, ceramic wastewater treated with the PAC+PAM combination can achieve:

• Effluent turbidity< paper size(removal rate > 99%)

• Suspendata solida (SS)below detection limit

The clear effluent can be fully recycled for floor washing, equipment cooling, or raw material spraying, enabling near‑zero discharge, saving water resources, and reducing environmental compliance costs.

7. Conclusion

Polyacrylamide est flocculans magnitudinis magnitudinis ceramic wastewater treatment. Selectione produktorum recta (typus anionis principis fluminis), co-dosing rational PAC, et operatio standardizata sunt claves effectionis et economicis trationis.
