Sludge Pits
During biological wastewater treatment processing, the precipitate, which mostly consists of sludge, is formed. Sludge pits are used to store this product.
In Bioks by Bioxica, the sediment is transferred to the sludge pit by the air-lift pump installations.
After compaction of sewage sludge, the liquid drifts to the head of the treatment facility while sediment is removed or fed to the dehydration unit.
At present, Bioxica uses the following sludge pits in Bioks:
- Metal sludge pits
- Fiberglass sludge pit
- Concrete sludge pits
Manufacture and supply of sludge pits
Bioxica develops and manufactures any additional equipment for treatment plants with a nonstandard approach, combining different technical capabilities.
The sludge pits are used for the disposal of excess active sewage sludge.
Bioxica designs, manufactures and supplies the sludge pits for treatment plants taking into account the wishes of the client in required sizes and materials.
Read MoreMetal sludge pits are steel containers of various sizes and configurations, usually recessed into the ground and equipped with two mouths for ventilation and auditing. For this purpose, there is a ladder in one of the mouths. The container is made of carbon steel, protected against corrosion by coating on both sides with anticorrosive materials.
The sludge pit is installed on a prepared reinforced concrete foundation.
Fiberglass sludge pits are durable, resistant, and perfect for any complex service conditions.
They do not corrode and do not require waterproofing, have a long service life, and are resistant to temperature and chemical wear. They are easy to transport and install.
Fiberglass sludge pit HELYX
The tank is installed in the foundation pit. Due to its light weight, tie belts made of synthetic non-elastic materials are set. This prevents displacement during backfilling and under the influence of surfacing groundwater
Tie belts are installed by fixing the sludge pit tank through special lugs, situated on the pre-erected reinforced concrete plate. This plate is usually made of monolithic concrete.
Concrete sludge pits are built on-site.
During production, the entire construction must be waterproofed.
In the case of uneven subsidence of structures or external influences, there is a risk of cracking, tightness, and sealing of the entire structure, which leads to additional costs.
Currently, reinforced concrete sludge pits are rarely used due to the relative labor intensity and significant construction time compared with plastic and metal sludge pits. These latter are delivered to the site, usually fully prefabricated.
