AERATION FOR TREATMENT FACILITIES
Aeration is an integral device that ensures the successful treatment of wastewater. It allows for the delivery of air at the appropriate pressure to optimize the treatment process, including aeration in various types of tanks.
Industrial aerators are capable of compressing air at low pressure. They function as compressors and vacuum pumps and are also used for backwashing filters at water treatment plants.
Modern aerators are designed with a focus on increasing treatment efficiency and ensuring maximum process safety, making them increasingly popular.
Rotary Air Blowers
Working wheels equipped with profiled gears provide:
Attention is also drawn to the increased service life of this type of device and the minimal frequency of failures.

Gratings for capturing coarse impurities
Застосування решіток допомагає знизити ризик забруднення обладнання на очисних спорудах, таких як насоси, аератори і т.д. Вони мають широкий спектр застосувань і використовуються на різних типах споруд, таких як рибні, м’ясні, фарбувальні, паперові, текстильні, молочні, насосні станції і т.д.
Розміри решіток вибираються відповідно до фактичних потоків і умов, що існують на конкретному об’єкті. Вони можуть бути встановлені в каналах різних розмірів, забезпечуючи ефективне утримання твердих часток і недопущення їх проникнення до обладнання. Решітки є важливим елементом для забезпечення безперебійної роботи систем очищення та збереження їх функціональності.

Installation for dewatering excess activated sludge
A screw press is a device used for compressing and dewatering sludge. It can operate automatically with minimal maintenance requirements.
For dewatering excess activated sludge at wastewater treatment plants, especially when processing 100 m3/day or more, it is recommended to install dewatering presses. This is particularly useful when there are no sludge lagoons available. “UKRBIOTAL” company can supply screw presses of Czech production as additional equipment.
The equipment for screw presses includes the press itself with a screw, a pump for feeding sludge from the sludge tank to the press chamber, as well as a flocculant dosing pump.
