The consultation concerns the provision of pumping and treatment of raw sludge
from the treatment of leachates produced by the rouzde technical landfill and transport of dewatered sludge to the non-hazardous waste storage facility in sainte-svre.
The characteristics of raw sludge
shown in Table 1 below and analyzed according to APHA Standard .
The DTF include a mechanical wastewater treatment plant; a biological treatment plant; a chlorination plant; a blowing station; a raw sludge
and excess activated sludge processing plant; a plant for dewatering sand and stabilized sludge in natural conditions; a storage pond; a household drinking water borehole facility.
The customer's previous macerator had been experiencing increasingly frequent blockages due to the 8-12% dried solids and fibre content of the raw sludge
it was handling.
Biogas production from sludge dosed with iron salts (Partly adapted from Smith, Carliell-Marquet 2009) Reference Type of analysis and Biogas production * sludge used Dentel, BT and SC, raw sludge
Gosset dosed in lab with Fe 21-32% less biogas (1982) and Al Mamais et al.
is loaded into stainless steel vessels where steam is injected and the sludge is held at high temperature and high pressure to kill bacteria.
Transferring raw sludge
from clarifiers to digester or from digester to sludge disposal facilities presents problems of removing too much water with the sludge.
Invitation to tender: Supply, installation and commissioning of three centrifuges for mechanical thickening of raw sludge
Minimum cytotoxicity was observed in roots treated with 10% sludge while maximum effect was obtained in roots treated with raw sludge
Tenders are invited for Renovation/ Overhauling of 150 mm dia Sluice Valve of Raw Sludge
Pump House at 45 MGD STP Okhla.
is loaded into stainless steel vessels, steam is injected and the sludge is then held at high temperature and pressure of 165C and six Bar.
The odor from raw sludge
, on the other hand, is a different problem, not only for the workers who are in close proximity to the odor, but also for those residents adjacent to the facility.
