Harlequin 18,400 Litre Hydroclear waste water system

The Hydroclear HC50 is ideal for the domestic market, and has been tested to EN 12566-3 and has a CE marking

With its unprecedented 24-month service period and enhanced capacities the HydroClear can dramatically reduce long term operating costs.

The HC50 model can easily be installed using a 2.5-tonne mini digger resulting in simple, cost effective installation with minimal damage to the surrounding area.

The model has a power failure default meaning that even if the power fails the HydroClear will continue performing as a septic tank to ensure continued environmental protection.

This system operates virtually silently, as this range of Hydroclear waste water system uses high performance diaphragm blowers.

Odours are minimised as the HydroClear is hermetically sealed and market leading performance means it effectively combats odour production.

The HydroClear HC50 offers a highly flexible solution to space-limited sites. With a pollutant removal level of 97%, and a de-sludging recommendation of 6 months, this model is efficient to run.
