| General Description: The Biwater rotating bar interceptor is convenient to use in pump chambers and sewage works inlets to protect pumps or fine screen mechanisms from damage by large, solid objects. The equipment comprises a series of rotating bars to form a grill with clear spaces set at 75mm, 100mm or 150mm dependent upon the limitations of solids size capable of being passed through the pumps. The tubular bars of large diameter rotate at a peripheral velocity approximately similar to the velocity of flow thereby presenting a moving surface. Rags and soft solids are encouraged to pass through by frequent clockwise and anti-clockwise rotation, a movement which also unwraps tailings and string-like materials which would otherwise tend to build up on the bars causing a blockage. A scraper mechanism is thus rendered superfluous. The passage of larger objects is prevented and only infrequent visual checking and removal is required by site operatives. Each bar’s rotation is achieved by independent hydraulic units which are capable of being submerged without damage. The power pack and timer control panel, which determines the rotation and duration of movement of the bars, can be located in a remote position away from the unpleasant and corrosive environment of the interceptor mechanism itself.  Installation is quick and simple usually requiring no site fixings whilst normal maintenance is minimal. The rotating bar interceptor will fill applications in new as well as existing channels for the protection of valuable down-stream equipment. |

Control Panel: The electrical control panel, fitted with an anti-condensation heater to be mounted adjacent to the hydraulic power pack contains the direct-on-line pump rotor starter, overloads, adjustable time switches, relays etc. controlling the bar operation. The Panel has a lockable handle on the front access door which operates the interlocked isolation switch, a remote/off/auto/selector switch, an ammeter, hours counter, front replacement indicating lamps to show overload tripped, bar staled, oil fitter blocked, high oil temperature and low oil pressure/flow. In addition to the time switches which give controlled reversal of the bars, there is an 8-180 minute initiation timer and an 8-180 second running timer. |
| Hydraulic Power Pack: The self contained hydraulic power pack is arranged for local or remote mounting and comprises a fabricated mild steel oil reservoir tank, side mounted combined oil tank gauge/thermometer and built in drip tray. The gear type oil pump is directly driven by a squirrel cage motor and the control valves connected into an integrated circuit allowing time controlled operation of the interceptor bars. Should one or more bars stall, due to overload, the remaining bars will continue in normal operation. |
