JOWA OIL-A TRIOSEP
Bilge water separator (OWS) with 15 ppm alarm
JOWA OIL-A TRIOSEP oily bilge water separator (MEPC 60(33)) consisting of three sequential stainless steel tanks: Tank 1 — gravity settler with oil level sensor CT01, Tanks 2 and 3 — coalescing filters with JOWA F200 activated carbon. After Tank 3, part of the flow goes to the 15 ppm alarm: upon exceedance, the pump stops, and the overboard discharge valve V7 closes. PLC control with display. Manual includes: technical data by size, installation, loading and replacement of filter material, operating principle, oil discharge, backwashing, start/stop, faults, maintenance, drawings, diagrams, and spare parts.

Maintenance procedures
Tank backwashing
- Wash before start and after operation, preferably with fresh water. Always start with Tank 3. p. 12
- Tank 3: turn handle V5 towards Tank 3, V11 — down, then open V8. Wash for 3–5 minutes. p. 12
- Tank 2: turn V5 towards Tank 2, V10 — down, then open V8. Wash for 3–5 minutes. p. 12
- Tank 1: turn V9 down, open V8, wash via V1. p. 12If V1 is connected to sludge tank — do not wash longer than necessary
Start after installation or repair
- Load F200 carbon into Tanks 2 and 3. p. 13
- Fill pump with water to prevent dry running. p. 13
- Open all valves from bilge tank to separator and on discharge line. p. 13
- Wash Tanks 2 and 3, ensure carbon dust and particles are removed. p. 13
- Fill Tank 1 with water to cover oil level sensor rod. p. 13
- Turn on power — separator is ready for operation. p. 13
Normal operation
- Open valves as for start; fill tanks with short backwash. p. 13
- During washing, vent residual oil and air via cocks on top of each tank. p. 13
- Turn power switch to position “1”, wait a few minutes. p. 13
- Reset faults with red pushbutton-lamp. p. 13
- Turn S2 to position 1 (auto): display shows >>>run<<<, pump is running. p. 13
Stop after operation
- Turn S2 to position «0». p. 14
- Flush the entire system by filling the tanks with clean fresh water. p. 14
- Close all valves to prevent the separator from draining. p. 14
- Clean the alarm sensor and keep it filled with clean water. p. 14
- Leave the power switch in position «1». p. 14
Replace filter material
- Disconnect power, shut off air and water supply. p. 9
- Open manual valves V12, V13 and drain water from filter tanks. p. 9
- Open top and bottom hatches, remove spent carbon. p. 9
- Thoroughly clean tanks of oil and dirt using a degreaser (e.g. JOWA MP 80). p. 9
- Fill with new carbon through top hatches to 60–70 % of volume (10–15 cm below top grids). p. 9Fill carefully to avoid breaking the grids inside the tanks
- Flush tanks 2 and 3 to remove carbon dust before operation. p. 13
