Pilot Plant Services Available

The pilot plant was configured to simulate as closely as possible the process train selection of a full-scale system. The pilot plant was designed for a maximum nominal throughput of 500 litres per day. The treatment offered by the pilot plant was to take place over a maximum of 4 steps, namely;

  1. Inlet Pre-filtration
  2. Ozone Reactor Vessel
  3. Multi-Media Filter
  4. Carbon Fiter

The frame holding these vessels was constructed of 2 wrap around 100 x 50mm stainless steel box section. Centrally placed in the frame was a bedplate to mount the Forward Feed Pump, Backwash Pump and Air-Scour Blower. Externally mounted on the frame was the Ozone Generator, The Control Panel / distribution panel and the system fascia / mimic.

The system was configured to be operated manually with respect to all filtering and washing sequences. However certain safeguards were incorporated such as low flow protection and overload cut outs on electrical loads. Flow through the system was controlled via a manually adjusted needle valve downstream and a variable area (Rotameter type) flowmeter on the inlet, this flowmeter was also fitted with a reed switch and magnetized float to give a low flow alarm contact. Refer to Figure 2 for details of the plant fascia mimic.

TK1 was configured to be backwashed using a combined air scour and backwash regime and consisted of a mono media sand of 0.7 to 1.4mm size. TK3 was configured for separate air and water backwashing with a high water upflow of the order of 30m/hr. media was sand identical to TK1 with a top layer of coarse filter anthracite. TK4 was configured for a water only wash, however a scour connection was provided as some types and grades of carbon will withstand and require air scouring.
