dewatered sludge

He said the county had not decided where the dewatered sludge would be taken.

Dewatered sludge has been managed in a number of ways since the plant opened.

At present the plant produces approximately 25 tonnes of dewatered sludge a day.

It also generates dewatered sludge which is transferred for off-site processing.

The transfer stream results from production of dewatered sludge, which is transferred off-site for processing.

The resulting dewatered sludge (or cake) dry solids concentration typically falls in the range of 12-50%.

The leachate or filtrate from the dewatered sludge, is further treated to ensure that it meets all requirements for industrial trade waste.

Dewatered sludge may be incinerated or transported offsite for disposal in a landfill or use as an agricultural soil amendment.

This allowed for more appropriate dewatering than the old open air lagooning with its associated odours, as well as providing a sustainable dewatered sludge disposal option.

Based on the above assumptions, the amount of phenol in the dewatered sludge is calculated based on the water in the sludge:

Gurabo WTP in co-operation with the City of Gurabo has made the dewatered sludge available to farmers.

On the solid residue dewatering side, our site-specific pretreatment investigations have identified additives which hold potential to significantly increase dewatered sludge cake consistency, and decrease chemical use.

Mr. Benjamin, the Tully spokesman, said the dewatered sludge was mixed with lime, wood ash, cement kiln dust and other ingredients to raise the pH level.

These fine screens capture small plastics and other rubbish which previously passed through into the final dewatered sludge (one reason for restricting possible use as compost), and this also assists downstream biological processes.

Under that plan, dewatered sludge would be trucked from the Yonkers plant to a new county-owned incinerator next to the existing solid-waste incinerator at Charles Point and the resulting ash would be trucked to a landfill.

From an initial concept of comminution and discharge to a long marine outfall, the design of the CVWPCC rapidly evolved to include primary and secondary treatment with aerated static pile composting of dewatered sludge.

Incineration or Conversion About 10 trucks a day, or a barge every two or three weeks, would remove the dewatered sludge to sites for incineration or for conversion into fertilizer or fuel pellets, Mr. Zabinksi said.

As the name suggests thermal sludge drying is a process where the dewatered sludge from a wastewater treatment plant is dried using external heat to produce a Class A sludge in accordance with USA EPA Rule 503.

No Clear Preference Nearly all of the 120 speakers at a recent public hearing in White Plains favored that third proposal: trucking the dewatered sludge to a rural, 45-acre site in Putnam Valley where it would be converted to an agricultural liming agent.
