Bad news for air quality over World Trade Center

However, current air quality in the area is now no longer affected by the disaster.

The TOVEKO® range of gravity sand filters
The TOVEKO® range of gravity sand filters wash the filter bed continuously while in service. Being only 2.3m high, they normally accept gravity flow. The sand washer is particularly effective at removing sticky & stubborn solids, keeping the bed clean at all times. The automatic head-loss detection system stops & starts filter operation, and adjusts the rate of sand washing according to the needs of the filter. It therefore needs very little attention, making it ideal for remote sites, and those where the inlet solids load fluctuates.
