For highly polluted waters ALTA GROUP 111 et al .

Mechanical cleaning container blocks are modular devices of full factory readiness for ground installation, insulated and having their own heating system. Designed for preliminary mechanical treatment of wastewater from the increased content of large suspended solids. The composition of the mechanical cleaning container unit includes two drum gratings and a pH neutralization module.

Averaging tanks are designed to average the uneven intake of heavily polluted wastewater during the day and to average the composition of wastewater. Sand traps are used to remove the increased content of fine suspended solids. To ensure the supply of wastewater from the averaging tank further for cleaning, a pumping pair is installed in the averaging tank with an installation on an automatic pipe coupling with guides (for convenient maintenance of pumps), as well as control automation. To prevent rotting and ensure mixing of wastewater, a pre-aeration system and equipment for collecting and removing sediment are installed in the averaging tank. Structural elements and parts of the averaging tanks in contact with wastewater are made of corrosion-resistant material — polypropylene. The service life is 50 years.

Denitrifiers are designed to restore nitrites and nitrates in highly polluted runoff to the state of free nitrogen, which is released into the atmosphere. Denitrifiers are modular devices of full factory readiness for underground installation, a controlled aeration system, sludge collection and removal equipment and an automatic agitator for mixing wastewater are installed inside. Structural elements and parts of denitrifiers in contact with wastewater are made of corrosion—resistant material - polypropylene. The service life is 50 years.

Alta bioreactor M nitrifiers are designed for the oxidation of ammonium nitrogen with oxygen to the state of nitrites and nitrates. The patented Alta Bioload bio-loading, sludge collection and removal equipment, reagent dosing system and controlled aeration system are installed inside. Structural elements and parts in contact with wastewater are made of corrosion—resistant material - polypropylene. The service life is 50 years.

Alta Laminar M thin-layer settling tanks are designed to separate mineral impurities, detached biomass particles and remove suspended solids. Thin-layer settling tanks include a thin-layer laminar module and a sediment accumulation zone (cone-shaped pit). Structural elements and parts are made of corrosion—resistant material - polypropylene. The service life is 50 years.

Block containers of the Alta Solid Trap dewatering system are designed for mechanical dewatering of sewage treatment plants sludge in order to reduce the volume of precipitation generated and reduce costs for their subsequent disposal. Dewatering units allow you to get a sediment with a humidity of 80% or less at the outlet. The composition of the dewatering system includes: a screw dehydrator, a flocculant preparation unit, a container for sediment accumulation.
