Continuous purification allows reuse of up to 95% of water, which significantly reduces the costs of the entire complex. The rotating disc filter does not require any specific maintenance and works in fully auto
Made entirely of stainless steel, the disc screen combines high structural strength, efficiency and simplicity rarely found in other equipment used for this purpose. Filtration of contaminated wastewater from suspended particles by a pair of vertical rotating discs has three important advantages:

  • Continuous self-cleaning of filter panels by accumulating waste.
  • Automatic discharge of waste when it accumulates (with the effect of partial dehydration)
  • Increased filtration effect on the vertical surface of the discs. Suspended particles fall on the filter panels not perpendicularly, but at an angle, due to which the filtration efficiency increases dramatically and can vary depending on the rotation speed of the discs (adjustable from 3 to 18 rpm).

Rotating discs screen has the following advantages:

up to 80%

Сокращает время очистки отстойников и простоя оборудования. Эффективно и быстро удерживает все мелкие и средние взвеси.

up to 95%

Загрязнения автоматически фильтруются на сетке от 0,1 мм.

Непрерывная очистка позволит Вам повторно использовать до 95% воды и существенно снизить издержки всего комплекса.

and mobile

  • Производить забор подлежащих фильтрации сточных вод питающим насосом из буферного резервуара, ёмкость которого составляет не менее 1/20 от суммарного суточного сброса сточных вод.

  • Устанавливать насосы с вихревым рабочим колесом, поскольку они способны поддерживать циркуляцию жидкостей.

Питание гидрофильтра может производиться самотёком
когда подлежащая фильтрации жидкость находится на такой высоте,
которая обеспечивает впуск во входную систему ГФ.

  • Если расход не является постоянным, то рекомендуется устанавливать буферный резервуар для гидравлической регулировки уровня питания гидрофильтра с постоянным расходом.


24 hours operation

High flow rate

The hydro-filter operates 24 hours a day. Solid particles fall on the filter panels not perpendicularly but at an angle so that filtration efficiency increases sharply also it can range due to the disks adjustable rotation speed.

More details

10 times finer filtration compared to traditional mechanical screens

Filter panels trap solids a size of 0.1 mm suspended in liquids depending on the mesh type used in filter. An additional filter layer that enhances the microfiltration ability creates sedimentation on the filter panels.

More details
Load reduction

For all subsequent stages of water treatment

Discharged solid material humidity can be adjusted by the discs rotation speed reducing or increasing – from 3 to 18 revolutions per minute. Solids excess are discharged automatically through the front opening between the discs.

More details
Automatic self-cleaning of discs

Automatic discs cleaning from sludge by a flushing system that consists from pipes equipped with injectors to spraying water supplied under pressure. While the sediment layer increases, the discs self-clean with the same solid sludge material.

More details
Corrosion resistance

Made entirely of AISI 304 stainless steel

The hydro-filter combines high design strength, efficiency and simplicity that finds in other equipment rarely. The filter container is made of stainless steel with thick of 3 mm and equipped with a protective cover.

More details
Compact size

Can be incorporated into any water treatment line, can be quickly reinstalled in a different place

The hydro-filter can be carried with a forklift. It must be installed on a horizontal surface that can bear the weight of the unit during operation including the amount of water contained in it.
