Diatomite Sludge Dewatering Aid CAS 68855‑54‑9 for Municipal Sewage Treatment
Diatomite Sludge Dewatering Aid CAS 68855‑54‑9 is industrial‑grade flux‑calcined diatomite specially used as sludge conditioning and dewatering aid for municipal sewage treatment. Its rigid porous particle structure can form stable permeable filter‑cake skeleton after mixing with sludge. It effectively destroys sludge colloid structure, improves filter‑cake permeability, lowers moisture content of dewatered sludge, and prevents filter cloth blockage. Chemically inert, it adapts to complex sewage
Product Overview
Diatomite Sludge Dewatering Aid CAS 68855‑54‑9 for Municipal Sewage TreatmentMunicipal biochemical sludge features high organic content, high viscosity and poor permeability, which easily causes filter cloth clogging, high cake moisture and low press efficiency during filter‑press dewatering. This diatomite dewatering aid is added for sludge conditioning. It constructs rigid skeleton inside sludge layer, opens up water‑passage channels, greatly improves dewatering efficiency and reduces final sludge cake moisture for subsequent transportation and incineration disposal.
Key Features
- CAS Number: 68855‑54‑9, Diatomite Sludge Dewatering Aid for Municipal Sewage
- Rigid particle skeleton, forms stable permeable filter‑cake structure
- Destroy viscous sludge colloids, reduce filter cloth blinding risk
- Significantly lower moisture content of filter‑pressed sludge cake
- Improve working efficiency of plate‑frame filter press and chamber filter press
- Good chemical inertness, adapt to variable pH conditions of municipal sludge
- Controlled particle‑size distribution, stable conditioning effect batch‑to‑batch
- Easy mixing with sludge, compatible with existing municipal sewage treatment process
Main Applications
‑ Sludge conditioning and dewatering aid for municipal sewage treatment plant‑ Auxiliary treatment for high‑viscosity biochemical excess sludge‑ Improve filter‑press performance of industrial combined sewage sludge‑ Pre‑treatment aid before sludge incineration, landfill and resource utilization
Usage Guidance
Mix evenly into sludge before filter pressing. Adjust dosage according to sludge concentration, viscosity and organic content. Conduct small‑scale dewatering test to confirm optimal addition proportion. Keep diatomite powder dry to prevent agglomeration. Wear dust mask during powder handling.
Storage & Package
Seal packages tightly. Store in dry ventilated warehouse, avoid moisture ingress. Standard package: 25kg woven bag with PE inner liner. Shelf life: 24 months under dry sealed storage.
Service Support
