Summary

Polyacrylamide (PAM) effectively removes solids and organic compounds from liquid swine manure. This treatment significantly reduces total suspended solids (TSS), volatile suspended solids (VSS), and chemical oxygen demand (COD) in wastewater.

Water Treatment
Agricultural Waste Management

Background:

Swine manure contains significant organic nutrients (nitrogen, phosphorus) and carbon compounds, primarily in suspended particles.
Separating solids from liquid swine manure is crucial for nutrient removal and waste management.
Flocculation with polyacrylamide (PAM) followed by screening is a promising method for solid-liquid separation.

Purpose of the Study:

To evaluate the efficiency of synthetic polyacrylamide (PAM) in treating liquid swine manure.
To quantify the removal of key pollutants after PAM treatment and screening.

Main Methods:

Liquid swine manure samples were treated with a synthetic polyacrylamide (PAM).
Treated samples underwent screening to separate solid and liquid fractions.

The liquid fraction was analyzed for concentrations of total suspended solids (TSS), volatile suspended solids (VSS), and chemical oxygen demand (COD).

Main Results:

Using 30 mg/L of PAM, the liquid fraction showed concentrations of 2.17 g/L for TSS, 1.93 g/L for VSS, and 16.42 g/L for COD.
These concentrations represent removal percentages of 94% for TSS, 94% for VSS, and 77% for COD from the swine manure.

Conclusions:

Synthetic polyacrylamide (PAM) is highly effective in removing TSS and VSS from liquid swine manure.
PAM treatment significantly reduces COD in swine manure, indicating its potential for wastewater treatment.
The combination of PAM flocculation and screening offers an efficient method for managing swine manure and its associated pollutants.
