As a sewer plant treats raw wastewater, a byproduct is created called biosolids. Biosolids, otherwise known as sludge, settle to the bottom of the treatment plant chambers and accumulate, taking up valuable design treatment capacity of the system. As the biosolids build up, the effectiveness of the treatment unit is compromised. The sludge has to be removed periodically to allow for proper continuing operations. Failure to remove the biosolids from the treatment plant can cause an effluent discharge that doesn't meet its authorized permitted values, which is a violation of environmental regulations. WWT construction and services can provide assessment and oversight of your biosolids management program. We are fully equipped with a trained staff and efficient equipment to properly remove and dispose of accumulated sludge.
There are times that the treatment bio-cycle is underfed with raw wastewater (ex. New plant just beginning operations, slow growing subdivision development, etc). We have the ability to take sludge from an efficiently operating treatment plant and introduce it into the underfed unit. This is known as biosolids reseeding and will assist the underfed unit to improve its ability to produce quality treated wastewater.
