Application:
Rotary screen is designed to separate coarse mechanic impurities from liquid. It is used rather conveniently as first stage of mechanic pretreating (preliminary clarification) within municipal or industrial waste water treatment plants (CPI - Corrugated Plate Interceptor) and anywhere where solid phase is required to become separated from the liquid one with minimal solid particle size of 5 mm.  |
 |
Function Description:
A liquid containing solid materials flows due to the gravity into the rotary screen via a supply nozzle (neck). While being treated the liquid flows over the screen perforation complete with undissolved materials (herein UMs only) smaller than 5 mm. UMs separated by means of the screen are then raked in a controlled manner by means of the raking arms, and pass right into the hopper of the hydraulic press’ operating chamber. Once inside the operating chamber the rackings get dewatered, pressed and sent to the container via conveyance piping. |

Specifications: Rotary screen is electric motor-driven using hydrostatic transmission. Motor power output installed equals to 0,37 kW. Hydro unit’s operating pressure is 16 MPa. There is fully automatic control with independent time adjustments for raking and pressing of rackings. There is either left-side or right-side supply of water to the rotary screen as required. Standard connection to the drainline uses sewer coupling of respective opening. If required flange connection or any other method are suitable to be made. Conveyance piping with pressed rackings is led at 45° or 90° angles. Maximal conveyance height of pressed rackings is 5 m (overhead the supply line axis). |

 |
Supply Specification:
The supply comprises rotary screen complete with hydraulic press designed for rackings, electric switchboard, control system and conveyance piping for rackings and terminated with flange DN 200, PN 6 of total length equal to 200 mm overhead D1 diameter. The basic version provides for anchoring rotary screen by means of frame to the supporting structure with anchore bolts spacing A x B. If required, please specify beforehand any other requirements concerning the anchoring and connection to the influent conduit. |

Terms:
Offer developed within 2 - 3 days. Equipment deliveries within ca 3 months.
Warranty and Service:
The equipment warranty is 24 months. After-guarantee service performance
is expected within two weeks after receipt of such order.
Advantage:
- Separation of undissolved materials along with their pressing and conveying are contained within one single unit.
- By pressing the rackings you minimalize their quantity and you constrain their odour to generate and propagate when water evaporates from non-compressed rackings and their decaying.
- Install your equipment right within the refill stations to enable for not installing disintegration pump that has higher electric power consumption, but instead use normal sludge pump.
- Hydrostatic transmission protects electric drive motor in a very efficient way against any damage caused by its overload.
- If required, the equipment can be fitted with the waterproof bottom and outfluent conduit full of pretreated water. Thus no precondition exists to carry out mechanic pretreatment with no need to build concrete channel, e.g. right within the screw pump discharge.
- Material version along with simple and robust stainless steel structure
ensures high lifetime.
The hydraulic drive chosen provides for incomparably lower demands in terms of maintenance, services and operation, when compared with drive rotary systems.
